honestly love the way you talk about this "the people who discovered how the climate naturally changes over time are climate scientists, the same group of people who discovered the climate change we're currently facing is human caused." is kind of a connection that should be obvious but it really hits different when spoken out loud. kind of a fun realization seeing how the reason the example comment at the start of the video knows about it in the first place are the same people he's trying to use that argument against.
This is actually a mistake in the video. Exxon found out about climate change more than 40 years ago. Climate scientist later on simply researched further into it.

@@kmoses582 Did you even watch the video? The argument is that the climate scientists, being the ones who discovered the natural cycles in the first place, already took them into account when coming to the conclusion that the current climate change crisis is man-made.
I've not got an issue with is it us or isn't it. I have an issue with us being told we need to be more "Carbon neutral" BUT the politicians don't actually do anything about it, they just take more money and MOVE the carbon footprint to another country to then say that we are doing out bit.
that is a very valid concern. we need governments to take this disaster seriously and make real efforts to restore our planet and prevent the further destruction of it. we must make them change
I get what you mean. I think that we definitly do have responsibility and should all try to reduce carbon since significant change can only happen if most people participate. It obviously is frustrating to see governments and companies to continue as before though, or also seeing rich people blast a bunch of CO2 into the athmosphere for a 10 minute trip with their private jets. Those are really significant factors that need to change, too, not just the general population. But the sad reality is that if you are wealthy and got power in this system, you will suffer less than many others that are less privileged and for example will have to leave their homes and countries or die as a result of climate change if we don't act now. Great, recent example which has angered a lot of people in germany: Just last month, a german company called RWE demolished a village called Lützerath in order to dig for estimated 280 million tons of carbon beneath it. They persuaded the people living there into selling their homes to them, and even though they got compensated, many felt pressured into that decision and aren't happy with it now. Lützerath also stopped getting supported by things like good public transport, kindergardens or supermarkets in order to make living there even less attractive. The government of northrhine-westphalia (the german state which Lützerath belonged to) allowed the demolishion after making deals with RWE. After harsh criticism, they started telling the population that we would need that carbon because of the energy crisis in correlation to the war in Ukraine, which is opposed by scientific institutes. Germsny actually managed to stop being dependent on russian oil, carbon and gas and stopped buying those in the beginning of 2023. We have enough reserves, too. Furthermore, the government acts like it's okay to demolish Lützerath because RWE has to leave the other villages in that area alone, like that's a fair compromise. Lützerath is even treated as a symbol for climate protection, which ignores the fact that it's more than that and that the decision has an actual impact. Our planet doesn't care about such compromises and symbols though, and even if we only use the carbon below Lützerath, germany still won't be able to meet the goals of the paris agreement on climate goals from 2015. Protesters occupied the village over multiple years but got evacuated by the police this january as a order of the government, so RWE can get to work. During the evacuation, 35.000 people also went there to protest. Police violence took place and the single officers didn't have individual numbers to be identifiable but instead only had group numbers, which makes it even harder to sue an officer for violence (besides the fact that it's already extremely hard to get justice when you literally have to go to the police for that). Companies such as RWE really try to profit as much off of carbon until they finally _have_ to stop in 2030, instead of taking responsibility asap and actually starting to reduce the use of carbon and extendimg climate friendly, renewable energy sources as much as possible. And our government protects these companies instead the future of humanity. We all need to start working together to solve this problem, or at least reduce the consequences as much we still can in order to protect this planet, but sadly it doesn't look too good.
@@astradose I think if ALL Governments around the world stopped using private jets for their meetings and just used the internet, that alone would be a saving worth more than millions of people turning off a light or TV or doing 1 less trip in the car. If they want us to start, they need to start showing some real concern at the top, because what they're saying doesn't match with anything they're doing. Like buying up all the cheap properties by the sea where they have scared off the residents. Doesn't seem quite right that after saying we'll be under water in 12 years. They're either lying to us or know something we don't. And for someone like Obama to buy that property for millions is a kick in the teeth.
@@astradose Do you actually believe that adding to a wisp of a trace gas, by a hundred parts per _million_ or so will cause a climate catastrophe? If so... Your Indoctrination is Complete. Carry on.
The science is clear: Man made climate change is a fact. The only uncertainly left in the science is how bad the effect will be. But the science is also says we can't take the risk to wait for the science to become more precise. Anyone that says we should do nothing is deliberate ignoring all the science for the sake of short term convenience. And what we actually do about it is inherently political.

The biggest problem that many people just comment whatever is in their heads without thinking for a second whenever it's really true. It often takes just 10 seconds to Google to find an answer, but many simply skipping that step...
Break the connection between Climate change, money, and power. Wait five years and see if there is still interest in climate change or if we shift our focus onto the next money or power grab. Humans have very short memories. Can humans do in a year (non-nuclear) what a single volcano can do to make a year without a summer?

In Hungary, our government just started forcing cutting out trees in a never before seen rate, and our way of handling natural values has never been good either. It's so sad.
Greetings from Germany, where we also have a growing populist and right wing part of our population. Mostly countryside, religious and not too well educated. It makes me sad to see what is becoming of hungary, the country that kind of started the opening of the iron curtain. Why are people voting for their own disadvantage? I speak with colleagues from Poland and Czech Republic and they also don't get why people vote for these authoritarian governments.
@@andreaswagner8356 Because nationalism and the fostering of a persecution complex towards the outside world is a great way to control the populace and keep them mad at those outside their borders rather than their leaders within them. After all, it's not the fault of Hungary's government policies for why you are poor, no, your problems all stem from our external enemies, like a foreign, Hungarian, Jewish billionaire!
Even if you take the debate out of climate change, what could be the harm in trying to clean up the environment we all live in, other than it might effect some billionaires profit margin, but what good is wealth without clean water to drink, fresh clean air to breathe, healthy natural food to eat and wildlife to appreciate and possibly learn from? Just because one arrogant neighbor chooses to live like an ignorant slob and doesn’t maintain their property, throws garbage, and other junk, in their yard, but still thinks they “know everything” about any subject (from looking at tiktok,), should everyone else just lower their standards and give up trying to take care of their own? Like it or not, High Tide Is Coming, isn’t it better to at least try our best to slow it down for the sake of future generations? Where is the harm in trying?
In the name of climate, they are promoting their agenda as if they are control our food, farming, property and no job in future, basically we will become useless eaters in the name of climate SORRY FOR MY BAD ENGLISH
That is never the debate. Everyone wants clean water, better planet. These jag offs want to spend trillions to SOLVE NOTHING. climate changes. And anyone who says it’s our fault and we can fix it is criminal and evil. Please research how much co2 levels were in the Jurassic period. And how well plants, insects and dinosaurs experienced their greatest growth.
the harm in trying comes from politicians. unfortunately your argument falters at the "what could be the harm" for that exact reason. left-leaning politicians are now forcing us to be more "carbon neutral" to reduce the amount of it even if it's doing virtually nothing. vehicles that use gas produce so little co2 compared to natural events such as volcanos. your whole arrogant snob neighbor thing is a different ordeal altogether, and i don't disagree that people should take common sense precautions such as using a trash bin, not littering out of pure laziness and having a recycle bin.
Where are all these "environmentalists" when it comes to actual pollution? like the slave labor and horrendous pollution in cobalt mining? Green Tech is NO WHERE near GREEN
Are you going to tell china , usa , India to lower their emissions..?? They make up 50% of the whole global emissions!! So unless you can tell them you ain't solving "climate change" . It does not matter what you do or say it will not solve a GLOBAL issue so say if a country Like canada has a total of 1 % of global emission . Say they start cutting their emissions by 50% lol that is only .5 of the global emissions.. ??? Like do the math ..
This is not simple. I've taken courses in meteorology, planetology and planetary science and everything here is included. More detail can be given on all of these which are based on physics included spectroscopy, atomic physics and quantum field theory. One thing left out is the feedback process of the melting of polar ice. Ice reflects 75 percent of the sunlight while water only 4 to 40 percent depending on the angle of sunlight. Water absorbs more light so the more than the north polar ice cap melts, the warmer it gets in that region due to more surface area of water and less ice. It is important to know that it's not just science, but physics. Meteorology and Climatology are based on physics, chemistry, geology, geochemistry which is chemistry and geology, oceanography, spectroscopy which is based on atomic physics and quantum field theory, astrophysics and astronomy. This video does have the correct physics.

I had my pager that day and thought nothing of it, but all the rest of the doctors in the hospital were blissfully unaware that the Emergency Room lit up and the nurses were screaming "Where are all the doctors? I've paged EVERYBODY!"
Now, imagine if we went through a Carrington-level event. This was a *MASSIVE* solar flare that affected telegraph equipment in 1859, caused Aurora Borealis displays as far south as San Diego, sparks and fires at battery installations at telegraph stations. People were reported to even be able to use telegraphs without any power connected at all during the flare. If a Carrington-level event were to happen today, chaos would result. It'd cause blackouts, damage the power-grid, and our satellite networks.

I was taught in school that the Earth has gone through multiple ice age cycles. The last one having just ended, though not sure what caused the previous ice-age events.
I was taught in school that the Earth has gone through multiple ice age cycles. The last one having just ended, though not sure what caused the previous ice-age events. Wayne Patterson --- You are mistaken, because the Late Cenozoic Ice Age extending from about 34 million years ago to the Present day and the Quaternary Glaciation 2.5 million years ago to the Present Day have not "just ended." What "just ended was the Last Glacial Maximum ~20,000 years ago to ~6,000 years ago when we entered the Holocene Climatic Optimum and interglacial period which will end with the next Glacial Maximum Period in the ongoing Late Cenozoic Ice Age. The causes are a combination of events with the continuing reductions of Atmospheric mass from greater than 100 atmospheres to less than 1 atmosphere in the future due to natural biological sequestration of Carbon dioxide being one of the key factors.
Per definition we are still in a deep ice age. It's defined by at least one pole being glaciered and currently both are. Plus we are just getting close to the roman climate optimum. Climate change is real, but it's in no way proven it's man-made. Also if you care so much about climate, stop the CO2 nonesense and start caring about the seas! Simply because of the curvature of earth, we would reflect way more than would stay inside, if CO2 really had such an effect. Or did the earth heated up last time a volcano erupted?
Humans ofcourse!They are the ones who do this,aint it so??No,the ones who are calling to lessen the CO 2 to prefent climate change are the ones who dont know nothing!!Years and years they are calling that the sea rise is steadily higher and the global temperature is steadily rising!And guess what ?The temperature globally isnt rising!The rising off sea level is still the same as it was for centuries!When there was no rising off CO 2!!
The last Ice age ended around 10,000 years ago. Ice core studies have shown it basically goes 100,000 years ice age/10,000 year warm period/100k Ice age/10k warm...repeated over and over as far as they have records for. So id say we are getting closer to another ice age. So what we need is MORE carbon dioxide. As the planet is actually cooling down. What happened to all the Acid rain? That was some genuine BS!

I think you have to mention that is not all of us guilty of global warming. It is mainly the rischest 10% of the people who consume most of the energy and emit most of the CO2 too. The poorest 50% of the people hardly emit any carbon. This is why economic inequality also has a big impact in our climate, scientists say...
I appreciate the vid and the explanation. But why do you use a graph at 3.00 min, where the distance down to -1.5% is equal to the distance up of 0.5%? According to the graph, the temperature dropped 1.5% from 1880 to 1910. From the 1940s to the 1970s it seems to have returned to the temperature of 1880. Then the temperature goes up approximately 0.8%, however the distance going up in the graph is three time that of the distance going down per 1%. As a result, the temperature going up from the 1970s seems visually much more than the shift down from 1880 to 1910, but the real temperature shift, according to your graph, has been 0.8% up compared to 1.5% down. Why did you make this skewd comparison?
To trick you into thinking that the temperature has dramatically increased in the last 40 to 50 years when the truth is it hasn't increased anymore than the models show the standard increase due to the fact that we are coming out of an Ice Age still the whole thing is about funneling money into corporations and large interest groups and transfer wealth from poor middle class people in the world to the wealthy
co-friendly building practices, integrating energy-efficient designs and materials, contribute substantially to reducing the carbon footprint of construction, heralding a shift toward more sustainable infrastructure.
It's okay. We are not in the extreme heat time. There has been warmer warming periods than this thousands of years ago, and they didn't have cars and stuff. It's fugazi, they planned this to spray the air with chemicals (they are protecting us ;)
Humans are part of the climate equation. The big question is can we move the needle more than non-human climate forces and whether those moves are detrimental to humanity. Do we think we can stop the next ice age?
Well, we are already in an ice age but I know what you mean. We probably can't stop long-term climate change, but we can certainly stop accelerating it from what should be a few million years to a couple hundred.

Except in North America co2 increases in Winter. Then drops quickly in spring all the way to end of Autumn at the 45th parallel. So does co2 circulate from China, Russia, Europe and the US? Probably. Or does it go to Southern hemisphere for a summer vacation? NASA does record it and it does happen every year in the northern hemisphere. Why is co2 added to a greenhouse environment?

The most important fact I learned in this video: it actually is called a "bald-faced lie!!!" I've been saying "bold-faced" for something like 40 years without any clue how wrong I was!
well if you havent figured out by now that mainstream lies constantly on just about everything for profits, then theres no hope for you. you could take all the greenhouse gases away and the climate will still change because this big sphere we are on is rotating on its axis and true north is migrating at the rate of 50 miles per year towards siberia, and the earth is only 8500 miles in circumference, whats 8500 divided by 50? since we have learned about pole shifts in the last 50 years how long do you think we have been slowly rotating on our axis? it doesnt mean we are going to get destroyed or anything, we have been goin nice and slow so far, and if it keeps up we will be fine, but eventually cold areas will move into warm ones and warm areas will move in to cold ones, like maine will end up were florida for an example, so ya the climate is going to change no matter what, scientist were talking about this 40 years ago, do even realize that 2/3 ds of the land in the world is empty. now i dont know if you follow elon musk, but he claims that the 7.9 billion we have now could fit in the size of new york, so the world is really under populated, not to mention that only 4 countries or so that have a less then 1% birth rate, the other 150+ countries have more deaths then births, so we arent really getting bigger, that is coming to an end, we will actually start going down in numbers. i dare you to check for yourself, a scientist that has studied the weather for over 70 years says the average temp hasnt increased or decreased more then 6 degrees in the last 100 years, hardly sounds like much global warming to me, i personally know the guy, i think ill take his word over some brainwashed twat that just repeating what the marxists have been crying about since the 70's. slow pole shift, expect it, its happening now!

This -18 degrees Celsius without a greenhouse effect would be the case assuming the Earth albedo would be identical to the current one. In reality it would be way lower due to the ice and snow, as would be the temperature. In fact during the periods of a snowball Earth, the poles were so cold that the condensation of CO2 was occuring there
@@johndennis5233 I know this derivation and the assumptions used in it. This -18 deg. C mean global temperature is obtained by inserting a current value of the Earth's albedo into that formula derived from the energy balance, with the outgoing energy given by Stefan-Boltzmann law and assuming that the Earth is a perfect blackbody in the longwave regime, but not taking the greenhouse effect into the account in this derivation. But of course one can expect that on such colder Earth a value of its albedo can be be greater (as one could anticipate a snowball Earth-like state). It would decrease the absorbed energy flux, thus resulting in a temperature lower that that -18 deg. C
@@johndennis5233 Seems OK with this value of an albedo :) Although honestly I cannot say what will be the exact Bond albedo of such a planet, it requires some complicated calculations to determine. But this value would also be my rough guess, though it is of course to be taken with a grain of salt
The argument I hear alot is not a denial of change or even denial that it's caused by humans, but that the rate of change is alarmist and that the earth will be able to absorb any change we throw at it and we will all be fine. I do not agree.

@@2KOOLURATOOLGaming I think it is a little more fundamental than people just being greedy. Capitalism is a teetering house of cards that requires continued growth to not fall apart entirely. Businesses need investment to keep the doors open and we are in a situation where profit margins are generally paper thin. Investment is how economic planning happens for the most part and investment will completely dry up in a system where nobody expects any return on investment and wealthy investors don't exist. And if that happens you will have a system that is incapable of innovation and providing for people's basic needs. I think the denialism is partly because some people have thought through the consequences of addressing climate change and realized it's incompatible with the continuation of capitalism and/or requires a huge intervention by the government, which they also don't like. They turn towards a kind of conspiracy that this is all made up by the left because they don't really have a solid market-based solution.
It's also about political leaning and religious beliefs, let's be honest. Deniers are listening to politicians who share their views on various topics, if that politician is wrong about this, they would have to acknowledge they could also be wrong about the other stuff they agree with. And that political side is likely not actively doing anything to combat climate change. So they can either acknowledge climate change is real and therefore acknowledge that they aren't doing anything to fix it to deny it's real. Denying it is a real problem justifies inaction.
The only difference it would make if the climate changes we're observing were natural is that the problem would be much harder to solve and we would need to act quicker and more aggressively.
The greatest known natural forcings on the climate are the Milankovitch Cycles and changes in solar irradiance, which on their own are in a cooling phase, but instead we see global warming. There is no reason to expect the forcings of solar irradiance and Milankovitch cycles, which are in a cooling phase, can overcome anthropogenic greenhouse gases. The last glaciation of the Pleistocene will be the last until CO2 goes back down, if ever.
Even if it were completely natural, that doesn't change the fact that it will be devastating for us if we don't do something about it now. We're the first species that's been able to understand it or that has the ability to control the climate. For the sake of our species, we should deal with it, regardless of the cause.
Control it is probably a bit strong but maybe influence the climate to be less extreme? Yours is the first sensible comment I've come across. Every body else seems to be politically motivated to move the blame to someone else. Imagine if the dinosaurs argued over who is going to fix the asteroid problem because it's 'not their fault'. Looks like we are still a long way away from actually implementing a possible solution.
@user-yy5or8lu8v Who says that humans have to be destructive to influence climate? Housing and buildings influence climate all around the world? It's only a case of 'all or nothing' if politics tells you that those are the only two choices. Moderation is usually a decent compromise for those who are actually looking for a working solution. For example an 8W light bulb uses one seventh of the power(energy use impact) of an equivalent 60W light bulb. You still have an impact, just a much smaller impact; but it does mean that you can still have lighting. Telling people to use low power consumption light bulbs is much more doable than scaremongering people to believe that they need to not have any lighting whatsoever in order to avert 'a total disaster'. But then it is easier to watch others not have lighting from your well lit home because you choose to blame them.
@user-yy5or8lu8v We can and do change the local climate with our non-insanely drastic actions. eg dams will change the local water cycle, or the excessive burning fossil fuels in Britain resulted in Scandinavian countries having more acidic rain. The key is to have a balance that allows for a decent quality of life. We can strive to be less wasteful in the way we do things, but we don't need the hypocritical finger pointing. Making products have a longer useful life is the 'LED lightbulb' upgrade for consumer products; but for political reasons it has little backing as companies don't want to meet consumer demand by producing less.
The big elephant in the room that is COMPLETELY remiss in this video is that humans have only released 1.4 parts CO2 to 10,000 parts atmosphere. To claim that this TINY amount of CO2 is altering Earth's climate is like trying to turn a molehill into a mountain.
@@tww7822 I've been alive for 6 decades and the approach of human caused climate catastrophe looks to me to be right on time. Depends if you get your "predictions" from the tabloids and other dumbed down and sensationalist sources, or not.
What I think is the biggest cause that is at the root of our current climate problem: we are with far too many people on this planet. For some reason "we" seem to believe that how well we are doing, is measured in progress. Progress is measured in technical prowess and the size of our economy, hoe much new stuff we produce and sell. "We" also seem to relentlessly want more of everything, consume more of everything. And at the same time our numbers are growing. But our resources are finite, as is the habitable space on the surface of our home.

Persistent westerly winds have also dragged the current in one direction for over 20 years, increasing the speed and size of the clockwise current and preventing the fresh water from leaving the Arctic Ocean. This decades-long western wind is unusual for the region, where previously, the winds changed direction every five to seven years. Scientists have been keeping an eye on the Beaufort Gyre in case the wind changes direction again. If the direction were to change, the wind would reverse the current, pulling it counterclockwise and releasing the water it has accumulated all at once. “If the Beaufort Gyre were to release the excess fresh water into the Atlantic Ocean, it could potentially slow down its circulation. And that would have hemisphere-wide implications for the climate, especially in Western Europe,” said Tom Armitage, lead author of the study and polar scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California. Fresh water released from the Arctic Ocean to the North Atlantic can change the density of surface waters. Normally, water from the Arctic loses heat and moisture to the atmosphere and sinks to the bottom of the ocean, where it drives water from the north Atlantic Ocean down to the tropics like a conveyor belt. This important current is called the Atlantic Meridional Overturning Circulation and helps regulate the planet’s climate by carrying heat from the tropically-warmed water to northern latitudes like Europe and North America. If slowed enough, it could negatively impact marine life and the communities that depend on it. “We don’t expect a shutting down of the Gulf Stream, but we do expect impacts. That’s why we’re monitoring the Beaufort Gyre so closely,” said Alek Petty, a co-author on the paper and polar scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The study also found that, although the Beaufort Gyre is out of balance because of the added energy from the wind, the current expels that excess energy by forming small, circular eddies of water. While the increased turbulence has helped keep the system balanced, it has the potential to lead to further ice melt because it mixes layers of cold, fresh water with relatively warm, salt water below. The melting ice could, in turn, lead to changes in how nutrients and organic material in the ocean are mixed, significantly affecting the food chain and wildlife in the Arctic. The results reveal a delicate balance between wind and ocean as the sea ice pack recedes under climate change. “What this study is showing is that the loss of sea ice has really important impacts on our climate system that we’re only just discovering,” said Petty.

Spammer. I've studied the history extensively. Vulcanic activity cause about 100times less CO2 than humans. Solar activity has been decreasing for decades. All of this is adressed in the video - why don't you actually watch it?
On the topic of volcanoes, the January volcano in Tonga is said to have spewed an extraordinary amount of seawater into the atmosphere due to its caldera being water, rather than the usual predominantly sulfurous magma, so this explosion has actually increased temperatures globally, rather than reducing them as Mt. St. Helens or Mt. Pinatubo did. Does this particular greenhouse effect of additional water molecules in the stratosphere potentially lead to yet another acceleration of warming, or is it another of the relatively minor effects that diminish over time as you discussed? Thank you for your wonderful explanations!
Water can’t increase to the same degree as others, because it induces rain much faster than these other slower balancing processes :) the main risk comes from extra heat increasing the water retention of air, rather than the emission of water itself.

I have a problem with massive multi-billion dollar companies wanting to keep providing extra carbon while blaming your car and your cheeseburger, trying to take both away from you while they buy "carbon credits" to keep polluting. also false or misleading advertising which fails to point out that you make a much bigger carbon footprint getting a new electric vehicle if you don't keep that one for over 6 years of driving. Or politicians who refuse to work on upgrading the power grid, tell us NOT to charge EVs, but tell us that we HAVE TO buy one, when they are still full of TOXIC lithium batteries while Humans have SUCH a spotless record when it comes to waste management (see pacific garbage patch). Lithium Apocalypse everyone ?
Bartist, you probably haven't heard of the salt battery didn't you? It's more efficient and you don't have to mine it, I mean its just concentrated salt and metals. That can be fully discharged unlike lithium batteries.
@@nushia7192 I have not heard of the salt battery, I have heard of the molten sodium solar mirror power plants and carbon batteries which they are still struggling to construct.
The carbon break-even point depends on how your electricity is generated which depends on where you live. If you live somewhere that still relies on coal powerplants, getting an EV isn't the planet-saving power move it would be if you lived somewhere using wind, solar, geothermal, or hydro. In the US, the break-even point is about 25k miles which is roughly 2.2 years of driving (Scientific American, March 2024).
@@nuynobi Thank you for putting in more effort than I did, providing improved precision and nuance over my vague generalization. I was more worried about my bacon cheeseburger future. Priorities.
Totally. EVs are such a scam. Lithium batteries are incredibly dangerous, you still have to charge your car with fossil fuels unless you wanna wait a few months and you need to mine them. The future of transport is public! Railway networks are absolutely amazing and incredibly efficient. You don’t need batteries for them (I think) and even if you did they carry so many people it’s ok, as well as that you waste very little energy because it’s steel on steel so there is very little friction. Driverless cars, busses and other solutions are not the future. Especially not driverless cars! Cities should also try and safely incorporate tram systems for efficient city trace and metros for large cities. Governments need to be investing on nuclear reactors because it’s much safer than traditional power plants and nuclear plants and the energy levels are INSANELY efficient. While not renewable they are zero emission and are probably the only power source capable of saving the planet because renewable energy is not advanced enough yet. In the future nuclear waste MAY be able to be sent to the moon to keep the planet safe and then later after we have all this spare nuclear power we can try setting up solar farms on planets closer to the sun and maybe one day a ‘Dyson swarm’ though that’s pretty far in the future. Edit: According to my grandfather who has worked (and still does) in the car industry for many years the protocol at a dealership if a lithium battery sets on fire is evacuate the building and wait. There is currently no way to put out a lithium fire other than waiting.

what is the optimal temperature for earth?

No one knows the absolute average Temp of Earth. Our ancestors failed us by not keeping record of such things. All we can do now is make a best guess from the data that is collected from Ice Cores in the northern and southern poles and a few other methods. As you can see, we have no accurate way of determining ancient past average temperatures on a global scale. It's all slight of hand.
@@brandonsheffield9873 The only measurement that can provide an average temperature is the satellite system operated by the U.S. gov't. The satellites are in polar orbits that take them around the Earth ≈14X every 24 hours. They cover every square meter of the planet every day, and their platinum resistence thermocouple (PRT) sensors are calibrated to a primary physical standard. The measurements are availble publicly, and if there was the slightest rise in global warming it would have been measured. In fact, the gov't satellites satellites show a slight _cooling_ trend began around 2014. As you wrote, there is no "average" earth temperature. The planet has been in a gradual cooling trend since the Holocene took it out of the last Ice Age. That cooling trend continues. Furthermore, CO2 has _no measurable effect_ on global temperatures. If it did the satellite data would have shown it, after the recent 50%+ rise in atmospheric CO2.

The phrase 'we were all ignorant once' isn't about insulting or calling people uneducated-it's a reminder that we all start somewhere. Climate science can be complex, and there's a lot of misinformation out there. The goal is to encourage learning and understanding, not to demean anyone. The more we learn about the science, the better equipped we are to address the challenges ahead.
In one day Al Gore has a carbon footprint that absolutely dwarfs anything to do with my carbon footprint in my lifetime. When Al Gore gets worried and cuts back to a level closer to me or less maybe I'll be motivated as well. Good luck with that you'll need it.
How did President Reagan put it? “It isn't so much that liberals are ignorant. It's just that they know so many things that aren't so.” This correlates to the progressive lefts religion of believing 100% in man made Climate Change because it is imbedded in their ideology (no proof required), even though true scientific evidence proves the opposite. The truth is that an increase in ocean temperature has to come first (500 - 800 years to heat up our deep oceans) before CO2 starts to increase, not the other away around. Ice core analysis clearly shows this fact, which contradicts Al Gore's Inconvenient Lie movie.
It’s really frustrating that people are still questioning this when this year alone we’ve seen the devastating effects of natural catastrophes intensified by climat change. And if you don’t « buy » the reality of climate change, biodiversity decline on its own should terrify us.

The UK used to be warmer for the Romans. When the Romans ruled Britain, known as the Roman Warm Period or Roman Climatic Optimum, is characterized by evidence of warmer conditions. This period, approximately from 250 BC to AD 400, was marked by unusually warm weather in Europe and the North Atlantic. During this time, there are indications that the climate was mild enough to allow for the cultivation of grapevines in regions such as northern England, which would typically be too cool for such crops today. The warmth of the Roman period is supported by various types of evidence, including tree ring data, which suggest that the climate was warmer than previously thought, potentially making the cultivation of certain crops like grapes in northern England feasible.
"The UK used to be warmer for the Romans" Even if true (I've never seen a source for this) - so what?? Local climate is influence by *loads* of factores, this tells us nothing about the rest of the world. "was marked by unusually warm weather in Europe and the North Atlantic." Indeed. But not globally. See Neukom et al (2019) 'No evidence for globally coherent warm and cold periods over the preindustrial Common Era'

20'000 years ago, Europe had the "Weichselian glaciation". The continent was covered by a 2000 by 3000 kilometer ice sheet that was up to 3 kilometers thick. The sea levels were 120 meters lower than they are today. No one knows for sure why this cold age ended. What we do know for sure is, that humans couldn't possibly have been the reason. Resonable climate change sceptics won't deny that humans influence the climate, they just say that human influence is tiny when compared to natural events.
Heat is always temporary, night time is always cooling, winter is always freezing and wild fires melt glaciers. 23.44 degree tilt determines/gaurantees that nothing can change unless we see a Volcano or Forest fire.
" they just say that human influence is tiny when compared to natural events" Which is.... nonsense. Globally averaged, change in temperature 20 000 to 10 000 years ago was about 4 °C. *Our* influence could cause a change by 4 °C in less than 200 years!

I’m confused about the graph you used there at 3:04. 3 steps for positive temperature changes, but only 1 step for the negative changes.. this looks like a trick to make it look like the temperature changes more in one specific direction.. plus it all started at 1880 which is funny in itself.
The labelling is indeed wrong. He blundered. If one looks up this, it's easy to see that it should be '-0.5 °C' instead. "this looks like a trick" Ever heard about 'honest mistakes' ??
"plus it all started at 1880 which is funny in itself." Since CO2 emissions were insignificant before 1880, why not?? If one looks at larger timescales, the point becomes even more apparent: a sudden steep rise in temperature.
@enderwiggin1113 That is not when CO2 picked up. In fact his statement about the chart was wrong as well. The industrial revolution started i1740 and more or less had concluded in 1880 so was CO2 taking a break for 100 years ?

an important question for all viewers of this regardless of what side you believe is “what piece of data or evidence would cause you to change your mind?”
A single piece? Certainly not. Science does not work this way. A good start would be a climate model which reproduces the observations *that* well like the ones with have, but without human factors.
over the last few years i have flipped back and forth several times as i come across different evidence and perspectives that cause me to rethink my stance. at the moment i’m undecided, focusing on building myself and my business first. maybe one day ill put forth the effort to form a sagacious opinion. as of now, it’s not that big of a deal for me atm
one thing i would be very interested in though is how the temperature measurements are being taken, by whom, where, when. that’s probably what i’d look into first
I did the math with figures from 7:40 graphic, and if ALL of the energy were deposited in the atmosphere, and none in the soil or oceans, the air would have increased its temperature by 18 degrees celcius every decade. Thanks to high heat capacity of water for not letting that happen i guess...
By ALL of the energy i mean all of those extra net 0.6 Wm^-2 absorbed by earth, after the atmosphere and earth radiated so much of the suns heat away as they could.
whoops, update after reaching 20:24 Turns out Joe got 60 degrees and not 18... Well imma have to get back into the calculations tomorrow to see if I can spot any mistake in my calculations...
All (99.999...%) of the incident solar radiation is re-radiated. There is an energy balance. If it accumulates even a little, you would have far, far more of a temperature rise than what you calculate.
Constant embarrasments for and from the scientific community will forever stay in conversations as examples of incompetance. Climate regulation cannot be changed.
Unfortunately it is hard to reason with people who believe. Great video, but not until we get several record high/low in the next few years that kills farmland and really messes things up, the remaining half of people won't buy the idea.
"people who believe" are those that believe this Global warming... Those that dont believe are the ones that can see that the Earth is greening (meaning has a higher carbon carrying capacity over time), and that the Earth is already reacting and handling the increase in CO2... This moron doesnt even cover that.
Our system would not be regulated without freezing and freezing is something that cannot be stopped, that's how California had record braking snow two years in a row.
Listening to this video made me realize that why the planet is warming is irrelevant. It is warming and much to fast for the ecosystems to adjust. We face mass extinctions and if humans want to continue to live, we should do something about it (even if we would not have been responsible). The fact that we are causing climate change means we are also able to get us out of that mess
Your comment makes no sense, you say that why the planet is warming is irrelevant. Then you say that we are causing it and means that we are able to get out of the mess. Then why is the source irrelevant? If it's mostly natural we have zero control.
@@kmoses582 (English is not my first language, maybe I am not good at explaining my thoughts) What I am trying to say is: whatever the source of the warming is, it is warming and there is dangerous consequences to it and we have to do something if we want to survive. Even if it were natural, we should try to get out of this mess. The only thing knowing we are the cause do, is giving us (me at least) some hope that we have power over it. Much more than if we were not.
@@sourisdebibliotheque The reason why I think understanding past climate is relevant is that it shows the changes we are going through now is not new or unprecedented. This helps us understand that human and wildlife alive today survived in the past and we will do just fine. Yes human activity is warming the world, but we must put it into perspective. I don't think we have any real control over our climate though, we are along for the ride.
A few questions I am seeing in skeptic discussions, maybe you could help clear them out: - What is the climate sensitivity for co2 or how much does earth warms upon a doubling of the co2 concentration in the atmosphere? What is this function? Is it a constant or it diminishes or increases depending the proportion of co2? - What is the average time it takes for a full cycle of a photon depositing energy from the sun onto the surface and returning back to space as radiation given co2 at 0ppm vs higher concentrations like 500ppm?
1) they dont know 2) they dont know What we do know is that the Earth is greening (more plants) as a result of the higher C02 levels, and we also know that plants are carbon capture mechanisms...
@@chrismcaulay7805 yes, that's a very good side effect of the co2 increasing. I think polution-wise co2 might be one the least problematic gases humans/animals emit given Earth's ecosystem.
@@chrismcaulay7805 what you are neglecting to take into account is that once co2 is in circulation it is in circulation until it is sequestered. The plants that may flourish under new conditions will eventually die and be eaten by bacteria and fungi that will release that carbon back to the athmosphere. Fossil fuels were created at a time when the athmosphere was toxic to species like ours AND when no organism was able to digest cellulose. This is no longer the case. All the carbon we free up is here to cycle through indefinitely.
The exact sensitivity to CO2 doubling isn't well pinned-down yet; it's usually quoted as 1.5-4.5oC or something like that. It's a big range, and a lot of people are trying to narrow it down. However, because of its narrow definition of "temperature increase at equilibrium due to doubling only CO2", there are circles in the community who don't find it super useful. There are many other GHGs besides CO2, and we certainly aren't emitting just CO2, and different regions will have their own sensitivity. Plus, as I think you're curious about, the sensitivity is definitely not constant over time. There are big arguments in the community over just how informative past climates might be in informing how future climates evolve. As a very simple example, an Earth that has massive ice caps will warm at a different rate than an Earth that doesn't have ice caps even if those two Earths absorb the same amount of energy. So it definitely changes, and it depends less on the amount of CO2 currently in the air and more on how much water is solid vs liquid, whether the most sunlight is falling on land vs ocean, things like that. You second question isn't known, and it's not a well-defined question itself, though I think I know more what you're getting at. Since it's nearly impossible to trace any single quanta of energy through the Earth system to figure out exactly when that Joule "enters" or "leaves", it's much easier to discuss the rates at which energy is entering or leaving the system. Think of it like water entering a lake from a river and then later evaporating - it's almost impossible (though definitely easier than for energy quanta) to track a single water molecule as it enters and leaves, and the actual times you'll get will range from "almost immediately" for surface water that evaporates almost immediately to "almost never" if that water makes it way to the bottom of the lake and stays there. However, by comparing the rate that the river feeds the lake against the rate of evaporation, we can figure out whether the lake is growing o drying out. Same thing with energy - we can see right now that there's an imbalance of (I believe) roughly 1 W/m2 at the top of the atmosphere, which is contributing to warming. Back when our atmosphere was closer to 280ppm CO2 instead of the 400+ it was now, there was basically no imbalance at all. If we were to somehow drop to 0ppm CO2, we'd definitely get an imbalance the other way toward cooling.
@Chris McAulay Yes, Earth is greening as a response to rising CO2. But as long as Earth is greening, that means that CO2 is rising faster than the plants are capturing it. As someone else already pointed out, plants aren't a permanent solution anyway, plus as the Earth continues to warm, temperature and water stress will outweigh the CO2 fertilization effect. Basically, the "greening" is a natural response to anthropogenic effects, and as the video already discussed, natural effects are a drop int he bucket versus the anthropogenic ones.

Must pur on my climate scientist har for a moment. I saw the thumbnail. Climate change is natural. What isn't natural is the rate of change. The rate is unprecenteded. In the past, climate swings took thousands of years. We have managed to completely shift the climate in just a few hundred. The last big climate swing we caused was due to agriculture and even that took over 1000 years. That is why we are all worried. It is hard to understand how species can adapt to climate shifts when every other change they have endured took eons to occur.
You are wrong, in this video he also made the point that climate change is not new but the rate of change is not. Then he went on to show nothing to back up that claim. It looks like the 1.1 C rise over 142 years looks fairly common when compared to many ice core samples. I think that is why he never showed that our recent change is unnatural, because its not.

Sadly, ignorance is a cornerstone of certain value and political groups. It’s no longer an information issue; it’s become a matter of fundamental “values”, and a matter of faith for certain people.
If someone says "climate change is natural" to me, I just reply "so is extinction, do you want that". Even if it was all natural, the fact is that we don't want change. We have built all of our infrastructure where it is now, over hundreds of years. If we allow climate change to happen, most of it will be lost at enormous cost. Not to mention all the food production that will also be lost. People complain about the costs of changing away from fossil fuels. But we are losing more from increased frequency of "natural" disasters, hurricanes, cyclones, flooding etc. It is also costing us in more costly food production. All of this denial is put about by fossil industry megalomaniacs who are only interested in their short term gains from the damage they cause.
Almost everything is reliant on fossil fuels. Even the IPCC in their report states there are no signals humans cause bad weather. Models predicting more bad weather is not any more factual than a 10 day weather forecast.
Why should you care about global food security, human suffering, increased mortality from weather events, increased severity from weather events, declining ocean fertility for major food sources, increased flooding events, increased drought events, climate migration from lower latitudes and elevations causing strife and war, etc etc etc.
I'm very curious about the volcanoes under the ice and the phreatic eruptions. As well as the tundra melting, is also getting washed into the arctic ocean and if the uptick in sea levels may cause the inland sea in the Praries in Canada would ahhh... become a thing again?
Gosh I hope not, that's where we grow all our food. The north part that's thawing is mostly what's known as "The Canadian Shield" and its basically a huge sheet of bedrock scraped clear by ancient glaciers that has a scattering of trees over it. Not exactly prime agricultural land, even if it warms up enough to be habitable to more than a few thousand people. I'm at the "gateway of the North" in Manitoba in The Pas and even here the winters hitting -40c for months and the numerous rocks and swamps make it a difficult place to grow stuff. At least long days in summer help but it's still damn depressing in winter.
@@danielled8665 I hear ya, I'm in Ontario! The tundra melting is way up in Nunavut on the arctic islands, NW territories n the Yukon. The footage is wicked, as it's melting its exposing old habitations but falling into the ocean so quickly that they can't survey or even collect archival materials from them. The inuit have a genome that enables them to thrive in incredibly cold climates bc their ancestors lived through the last iceage, followed the caribou over the Baring straight ice Bridge approx 30 000 years ago!
I watched an Artic Ice extent timelaps for the past 45 years and the Ice goes to the same extent every single winter, thats a really stable and regulated climate.
Very pertinent point. We've seen Greta Thunberg's anger and the numbness of shock that most folk experience when they first understand the extent of what's coming. Then there's denial. Alas, a lot of denial is bolstered by misinformation from greedy folk wanting to continue to pollute. That keeps overwhelmed people stuck in denial.
That same argument works to explain why we've been hearing nothing but extreme doom and gloom predictions for four decades that haven't come true. None of them. Your beachfront property is still your beachfront property, the world is actually getting greener, I know world is not consistently getting warmer, which is why they went from global warming to climate change.
Humans have only added 1.4 parts CO2 to 10,000 parts atmosphere. If you still believe that this TINY amount of CO2 is causing the climate to change, then that is denial. I want to sell you the Brooklyn Bridge if you think CO2 climate change is real.
We hear about "trigger points" all the time now a days. Since the last ice age, the glacial front has receded about 20 miles per year. As these glacial recede, they reveal darker masses underneath them. These darker masses absorb more heat than would have been reflected by the ice sheets. So, as more and more of these dark masses where revealed, did we hit a "trigger point" that accelerated the melting and allowed for more temperature absorption?
SittingInDetroit --- So, as more and more of these dark masses where revealed, did we hit a "trigger point" that accelerated the melting and allowed for more temperature absorption? Wayne Patterson --- No. The Solar thermal energy resident within the Atmosphere is somewhere on the order of only about 17 percent of the Earth's gain in Solar energy. The vast majority of the Solar thermal gain is resident in the Hydrosphere and Cryosphere. Consequently, the currently small percentage change in the land surface albedo in the absence of the Cryosphere is relatively insignificant for the Earth as a whole.
SID: Tipping points (or trigger points as you call them) refer to situations where some kind of discontinuity is passed. The reduction in albedo due to loss of snow/ice cover (whether on land or sea) is certainly a positive feedback to warming, as you suggest, due to the reduction in the amount of incoming solar radiation that is reflected (harmlessly) back into space. (Wayne's comment doesn't make sense). Trouble is we don't know with any great certainty when we might cross the various possible tipping points. This article in Nature also has a number of references: Nature "Climate tipping points - too risky to bet against" 27 November 2019
@@Tengooda Something that is seldom talked about is the worlds temperature rise number is made up of 100s/1000s of measurements. The trend is that the colder areas are changing at a higher rate while the warmer areas are not changing or very little. This leads me to wonder about the increased land mass theory.
@@waynepatterson5843 So, you believe that the whole "tipping point" is not true. The "tipping point" theory says that a very small change can be the last bit that causes massive and accelerated change.

I've not got an issue with is it us or isn't it. I have an issue with us being told we need to be more "Carbon neutral" BUT the politicians don't actually do anything about it, they just take more money and MOVE the carbon footprint to another country to then say that we are doing out bit.
that is a very valid concern. we need governments to take this disaster seriously and make real efforts to restore our planet and prevent the further destruction of it. we must make them change
I get what you mean. I think that we definitly do have responsibility and should all try to reduce carbon since significant change can only happen if most people participate. It obviously is frustrating to see governments and companies to continue as before though, or also seeing rich people blast a bunch of CO2 into the athmosphere for a 10 minute trip with their private jets.
Those are really significant factors that need to change, too, not just the general population.
But the sad reality is that if you are wealthy and got power in this system, you will suffer less than many others that are less privileged and for example will have to leave their homes and countries or die as a result of climate change if we don't act now.
Great, recent example which has angered a lot of people in germany:
Just last month, a german company called RWE demolished a village called Lützerath in order to dig for estimated 280 million tons of carbon beneath it.
They persuaded the people living there into selling their homes to them, and even though they got compensated, many felt pressured into that decision and aren't happy with it now. Lützerath also stopped getting supported by things like good public transport, kindergardens or supermarkets in order to make living there even less attractive.
The government of northrhine-westphalia (the german state which Lützerath belonged to) allowed the demolishion after making deals with RWE.
After harsh criticism, they started telling the population that we would need that carbon because of the energy crisis in correlation to the war in Ukraine, which is opposed by scientific institutes. Germsny actually managed to stop being dependent on russian oil, carbon and gas and stopped buying those in the beginning of 2023. We have enough reserves, too.
Furthermore, the government acts like it's okay to demolish Lützerath because RWE has to leave the other villages in that area alone, like that's a fair compromise. Lützerath is even treated as a symbol for climate protection, which ignores the fact that it's more than that and that the decision has an actual impact. Our planet doesn't care about such compromises and symbols though, and even if we only use the carbon below Lützerath, germany still won't be able to meet the goals of the paris agreement on climate goals from 2015.
Protesters occupied the village over multiple years but got evacuated by the police this january as a order of the government, so RWE can get to work. During the evacuation, 35.000 people also went there to protest. Police violence took place and the single officers didn't have individual numbers to be identifiable but instead only had group numbers, which makes it even harder to sue an officer for violence (besides the fact that it's already extremely hard to get justice when you literally have to go to the police for that).
Companies such as RWE really try to profit as much off of carbon until they finally _have_ to stop in 2030, instead of taking responsibility asap and actually starting to reduce the use of carbon and extendimg climate friendly, renewable energy sources as much as possible.
And our government protects these companies instead the future of humanity.
We all need to start working together to solve this problem, or at least reduce the consequences as much we still can in order to protect this planet, but sadly it doesn't look too good.
@@astradose I think if ALL Governments around the world stopped using private jets for their meetings and just used the internet, that alone would be a saving worth more than millions of people turning off a light or TV or doing 1 less trip in the car. If they want us to start, they need to start showing some real concern at the top, because what they're saying doesn't match with anything they're doing. Like buying up all the cheap properties by the sea where they have scared off the residents. Doesn't seem quite right that after saying we'll be under water in 12 years. They're either lying to us or know something we don't. And for someone like Obama to buy that property for millions is a kick in the teeth.

This is not simple. I've taken courses in meteorology, planetology and planetary science and everything here is included. More detail can be given on all of these which are based on physics included spectroscopy, atomic physics and quantum field theory. One thing left out is the feedback process of the melting of polar ice. Ice reflects 75 percent of the sunlight while water only 4 to 40 percent depending on the angle of sunlight. Water absorbs more light so the more than the north polar ice cap melts, the warmer it gets in that region due to more surface area of water and less ice. It is important to know that it's not just science, but physics. Meteorology and Climatology are based on physics, chemistry, geology, geochemistry which is chemistry and geology, oceanography, spectroscopy which is based on atomic physics and quantum field theory, astrophysics and astronomy.

I was taught in school that the Earth has gone through multiple ice age cycles. The last one having just ended, though not sure what caused the previous ice-age events.
Wayne Patterson --- You are mistaken, because the Late Cenozoic Ice Age extending from about 34 million years ago to the Present day and the Quaternary Glaciation 2.5 million years ago to the Present Day have not "just ended." What "just ended was the Last Glacial Maximum ~20,000 years ago to ~6,000 years ago when we entered the Holocene Climatic Optimum and interglacial period which will end with the next Glacial Maximum Period in the ongoing Late Cenozoic Ice Age. The causes are a combination of events with the continuing reductions of Atmospheric mass from greater than 100 atmospheres to less than 1 atmosphere in the future due to natural biological sequestration of Carbon dioxide being one of the key factors.
Per definition we are still in a deep ice age. It's defined by at least one pole being glaciered and currently both are.
Plus we are just getting close to the roman climate optimum.
Climate change is real, but it's in no way proven it's man-made.
Also if you care so much about climate, stop the CO2 nonesense and start caring about the seas!
Simply because of the curvature of earth, we would reflect way more than would stay inside, if CO2 really had such an effect.
Or did the earth heated up last time a volcano erupted?
Humans ofcourse!They are the ones who do this,aint it so??No,the ones who are calling to lessen the CO 2 to prefent climate change are the ones who dont know nothing!!Years and years they are calling that the sea rise is steadily higher and the global temperature is steadily rising!And guess what ?The temperature globally isnt rising!The rising off sea level is still the same as it was for centuries!When there was no rising off CO 2!!

The last Ice age ended around 10,000 years ago. Ice core studies have shown it basically goes 100,000 years ice age/10,000 year warm period/100k Ice age/10k warm...repeated over and over as far as they have records for.

FUN FACT: CO2 levels have only gone up 1.3 parts per 10,000 since 1880. Too tiny to have moved the thermometer by any measurable amount.
I appreciate the vid and the explanation. But why do you use a graph at 3.00 min, where the distance down to -1.5% is equal to the distance up of 0.5%? According to the graph, the temperature dropped 1.5% from 1880 to 1910. From the 1940s to the 1970s it seems to have returned to the temperature of 1880. Then the temperature goes up approximately 0.8%, however the distance going up in the graph is three time that of the distance going down per 1%. As a result, the temperature going up from the 1970s seems visually much more than the shift down from 1880 to 1910, but the real temperature shift, according to your graph, has been 0.8% up compared to 1.5% down. Why did you make this skewd comparison?
All of this climate data is skewed.
To trick you into thinking that the temperature has dramatically increased in the last 40 to 50 years when the truth is it hasn't increased anymore than the models show the standard increase due to the fact that we are coming out of an Ice Age still the whole thing is about funneling money into corporations and large interest groups and transfer wealth from poor middle class people in the world to the wealthy

So does co2 circulate from China, Russia, Europe and the US? Probably. Or does it go to Southern hemisphere for a summer vacation?
NASA does record it and it does happen every year in the northern hemisphere. Why is co2 added to a greenhouse environment?

well if you havent figured out by now that mainstream lies constantly on just about everything for profits, then theres no hope for you. you could take all the greenhouse gases away and the climate will still change because this big sphere we are on is rotating on its axis and true north is migrating at the rate of 50 miles per year towards siberia, and the earth is only 8500 miles in circumference, whats 8500 divided by 50? since we have learned about pole shifts in the last 50 years how long do you think we have been slowly rotating on our axis? it doesnt mean we are going to get destroyed or anything, we have been goin nice and slow so far, and if it keeps up we will be fine, but eventually cold areas will move into warm ones and warm areas will move in to cold ones, like maine will end up were florida for an example, so ya the climate is going to change no matter what, scientist were talking about this 40 years ago, do even realize that 2/3 ds of the land in the world is empty. now i dont know if you follow elon musk, but he claims that the 7.9 billion we have now could fit in the size of new york, so the world is really under populated, not to mention that only 4 countries or so that have a less then 1% birth rate, the other 150+ countries have more deaths then births, so we arent really getting bigger, that is coming to an end, we will actually start going down in numbers. i dare you to check for yourself, a scientist that has studied the weather for over 70 years says the average temp hasnt increased or decreased more then 6 degrees in the last 100 years, hardly sounds like much global warming to me, i personally know the guy, i think ill take his word over some brainwashed twat that just repeating what the marxists have been crying about since the 70's. slow pole shift, expect it, its happening now!

This -18 degrees Celsius without a greenhouse effect would be the case assuming the Earth albedo would be identical to the current one. In reality it would be way lower due to the ice and snow, as would be the temperature. In fact during the periods of a snowball Earth, the poles were so cold that the condensation of CO2 was occuring there
@@johndennis5233 I know this derivation and the assumptions used in it. This -18 deg. C mean global temperature is obtained by inserting a current value of the Earth's albedo into that formula derived from the energy balance, with the outgoing energy given by Stefan-Boltzmann law and assuming that the Earth is a perfect blackbody in the longwave regime, but not taking the greenhouse effect into the account in this derivation. But of course one can expect that on such colder Earth a value of its albedo can be be greater (as one could anticipate a snowball Earth-like state). It would decrease the absorbed energy flux, thus resulting in a temperature lower that that -18 deg. C
@@johndennis5233 Seems OK with this value of an albedo :) Although honestly I cannot say what will be the exact Bond albedo of such a planet, it requires some complicated calculations to determine. But this value would also be my rough guess, though it is of course to be taken with a grain of salt
Thanks for actually engaging with this argument.

I always feel like the narrative that says that climate change is not our fault, is fueled by a desire to keep living our lives the same way we are doing now. Continue buying stuff, producing stuff, driving cars everywhere. This denial of the facts seems also fueled by our general innate resistance to change and our desire for continued short term economic profit 🤷♀️ If everyone changed their ways all at once, how are these climate change causing industries continue to make money? Naw, better to say it is not your fault so please keep consuming as you’ve been consuming for the past decades instead of changing 🤷♀️😑
Maintaining the planet actually helps that in favor of capitalism, how? if we maintain the planet to be habitable, there'd be more people buying stuff. Less habitable planet means less people buying.
@@nushia7192 But people and executives run corporations, the same people who are selfish and want higher profits and income are the same people who only care about their lives. Therefore it is not in their interest to help future executives so why would they take a hit to the business by changing people's lifestyles when it will only help other people. They'll be dead before things get bad enough that their money can't keep them comfortable.
Basically, although we often think of Capitalism as an entity, any idea of preparing the world for the same status quo disappears if people aren't there to benefit from it.
Edit: damnit this descended into a ramble.
I am just saying that, no it isn't necessarily in the interest of capitalism to keep people alive and comfortable in a hellish future because people are selfish and eventually they will be dead and won't benefit. What matters to them is people buying now and the best way to do that is keep them living and buying exactly the same way we are now.
@@2KOOLURATOOLGaming I think it is a little more fundamental than people just being greedy. Capitalism is a teetering house of cards that requires continued growth to not fall apart entirely. Businesses need investment to keep the doors open and we are in a situation where profit margins are generally paper thin. Investment is how economic planning happens for the most part and investment will completely dry up in a system where nobody expects any return on investment and wealthy investors don't exist. And if that happens you will have a system that is incapable of innovation and providing for people's basic needs. I think the denialism is partly because some people have thought through the consequences of addressing climate change and realized it's incompatible with the continuation of capitalism and/or requires a huge intervention by the government, which they also don't like. They turn towards a kind of conspiracy that this is all made up by the left because they don't really have a solid market-based solution.
@@nushia7192 Rave on.
It's also about political leaning and religious beliefs, let's be honest. Deniers are listening to politicians who share their views on various topics, if that politician is wrong about this, they would have to acknowledge they could also be wrong about the other stuff they agree with. And that political side is likely not actively doing anything to combat climate change. So they can either acknowledge climate change is real and therefore acknowledge that they aren't doing anything to fix it to deny it's real. Denying it is a real problem justifies inaction.
The only difference it would make if the climate changes we're observing were natural is that the problem would be much harder to solve and we would need to act quicker and more aggressively.
The greatest known natural forcings on the climate are the Milankovitch Cycles and changes in solar irradiance, which on their own are in a cooling phase, but instead we see global warming. There is no reason to expect the forcings of solar irradiance and Milankovitch cycles, which are in a cooling phase, can overcome anthropogenic greenhouse gases. The last glaciation of the Pleistocene will be the last until CO2 goes back down, if ever.
@@rps1689forest fires melt glaciers.
LITERALLY!!! Even if it isn’t caused by us, we still have a giant ass problem to solve.
Even if it were completely natural, that doesn't change the fact that it will be devastating for us if we don't do something about it now. We're the first species that's been able to understand it or that has the ability to control the climate. For the sake of our species, we should deal with it, regardless of the cause.
This is true.
I don't think we can do much about the natural part of climate change. But that part isn't noticeable over decades like the human induced part is.
Control it is probably a bit strong but maybe influence the climate to be less extreme? Yours is the first sensible comment I've come across. Every body else seems to be politically motivated to move the blame to someone else. Imagine if the dinosaurs argued over who is going to fix the asteroid problem because it's 'not their fault'. Looks like we are still a long way away from actually implementing a possible solution.
@user-yy5or8lu8v Who says that humans have to be destructive to influence climate? Housing and buildings influence climate all around the world? It's only a case of 'all or nothing' if politics tells you that those are the only two choices. Moderation is usually a decent compromise for those who are actually looking for a working solution.
For example an 8W light bulb uses one seventh of the power(energy use impact) of an equivalent 60W light bulb. You still have an impact, just a much smaller impact; but it does mean that you can still have lighting. Telling people to use low power consumption light bulbs is much more doable than scaremongering people to believe that they need to not have any lighting whatsoever in order to avert 'a total disaster'. But then it is easier to watch others not have lighting from your well lit home because you choose to blame them.
@user-yy5or8lu8v We can and do change the local climate with our non-insanely drastic actions. eg dams will change the local water cycle, or the excessive burning fossil fuels in Britain resulted in Scandinavian countries having more acidic rain. The key is to have a balance that allows for a decent quality of life. We can strive to be less wasteful in the way we do things, but we don't need the hypocritical finger pointing. Making products have a longer useful life is the 'LED lightbulb' upgrade for consumer products; but for political reasons it has little backing as companies don't want to meet consumer demand by producing less.

What I think is the biggest cause that is at the root of our current climate problem: we are with far too many people on this planet.
For some reason "we" seem to believe that how well we are doing, is measured in progress. Progress is measured in technical prowess and the size of our economy, hoe much new stuff we produce and sell. "We" also seem to relentlessly want more of everything, consume more of everything. And at the same time our numbers are growing. But our resources are finite, as is the habitable space on the surface of our home. The surface that is not habited, is either uninhabitable, or used for growing our food - which we need more and more of. The balance is off way in the wrong direction. Technology isn't going to solve this.
Vermont students claim insects were found 2 miles under the Ice in Greenland confirming a recent Ice Age. They claim humans will cause the same effects that occured 1000s of years ago, how convienent this explantion is.
Persistent westerly winds have also dragged the current in one direction for over 20 years, increasing the speed and size of the clockwise current and preventing the fresh water from leaving the Arctic Ocean. This decades-long western wind is unusual for the region, where previously, the winds changed direction every five to seven years.
Scientists have been keeping an eye on the Beaufort Gyre in case the wind changes direction again. If the direction were to change, the wind would reverse the current, pulling it counterclockwise and releasing the water it has accumulated all at once.
“If the Beaufort Gyre were to release the excess fresh water into the Atlantic Ocean, it could potentially slow down its circulation. And that would have hemisphere-wide implications for the climate, especially in Western Europe,” said Tom Armitage, lead author of the study and polar scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California.
Fresh water released from the Arctic Ocean to the North Atlantic can change the density of surface waters. Normally, water from the Arctic loses heat and moisture to the atmosphere and sinks to the bottom of the ocean, where it drives water from the north Atlantic Ocean down to the tropics like a conveyor belt.
This important current is called the Atlantic Meridional Overturning Circulation and helps regulate the planet’s climate by carrying heat from the tropically-warmed water to northern latitudes like Europe and North America. If slowed enough, it could negatively impact marine life and the communities that depend on it.
“We don’t expect a shutting down of the Gulf Stream, but we do expect impacts. That’s why we’re monitoring the Beaufort Gyre so closely,” said Alek Petty, a co-author on the paper and polar scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
The study also found that, although the Beaufort Gyre is out of balance because of the added energy from the wind, the current expels that excess energy by forming small, circular eddies of water. While the increased turbulence has helped keep the system balanced, it has the potential to lead to further ice melt because it mixes layers of cold, fresh water with relatively warm, salt water below. The melting ice could, in turn, lead to changes in how nutrients and organic material in the ocean are mixed, significantly affecting the food chain and wildlife in the Arctic. The results reveal a delicate balance between wind and ocean as the sea ice pack recedes under climate change.
“What this study is showing is that the loss of sea ice has really important impacts on our climate system that we’re only just discovering,” said Petty.

All of this is adressed in the video - why don't you actually watch it?
On the topic of volcanoes, the January volcano in Tonga is said to have spewed an extraordinary amount of seawater into the atmosphere due to its caldera being water, rather than the usual predominantly sulfurous magma, so this explosion has actually increased temperatures globally, rather than reducing them as Mt. St. Helens or Mt. Pinatubo did. Does this particular greenhouse effect of additional water molecules in the stratosphere potentially lead to yet another acceleration of warming, or is it another of the relatively minor effects that diminish over time as you discussed? Thank you for your wonderful explanations!
Water can’t increase to the same degree as others, because it induces rain much faster than these other slower balancing processes :) the main risk comes from extra heat increasing the water retention of air, rather than the emission of water itself.

Totally. EVs are such a scam. Lithium batteries are incredibly dangerous, you still have to charge your car with fossil fuels unless you wanna wait a few months and you need to mine them.
The future of transport is public! Railway networks are absolutely amazing and incredibly efficient. You don’t need batteries for them (I think) and even if you did they carry so many people it’s ok, as well as that you waste very little energy because it’s steel on steel so there is very little friction.
Driverless cars, busses and other solutions are not the future. Especially not driverless cars!
Cities should also try and safely incorporate tram systems for efficient city trace and metros for large cities.
Governments need to be investing on nuclear reactors because it’s much safer than traditional power plants and nuclear plants and the energy levels are INSANELY efficient. While not renewable they are zero emission and are probably the only power source capable of saving the planet because renewable energy is not advanced enough yet.
In the future nuclear waste MAY be able to be sent to the moon to keep the planet safe and then later after we have all this spare nuclear power we can try setting up solar farms on planets closer to the sun and maybe one day a ‘Dyson swarm’ though that’s pretty far in the future.
Edit: According to my grandfather who has worked (and still does) in the car industry for many years the protocol at a dealership if a lithium battery sets on fire is evacuate the building and wait. There is currently no way to put out a lithium fire other than waiting.

This correlates to the progressive lefts religion of believing 100% in man made Climate Change because it is imbedded in their ideology (no proof required), even though true scientific evidence proves the opposite. The truth is that an increase in ocean temperature has to come first (500 - 800 years to heat up our deep oceans) before CO2 starts to increase, not the other away around.

The UK used to be warmer for the Romans. When the Romans ruled Britain, known as the Roman Warm Period or Roman Climatic Optimum, is characterized by evidence of warmer conditions. This period, approximately from 250 BC to AD 400, was marked by unusually warm weather in Europe and the North Atlantic.
During this time, there are indications that the climate was mild enough to allow for the cultivation of grapevines in regions such as northern England, which would typically be too cool for such crops today. The warmth of the Roman period is supported by various types of evidence, including tree ring data, which suggest that the climate was warmer than previously thought, potentially making the cultivation of certain crops like grapes in northern England feasible.

Climate change is natural.
20'000 years ago, Europe had the "Weichselian glaciation".
The continent was covered by a 2000 by 3000 kilometer ice sheet that was up to 3 kilometers thick.
The sea levels were 120 meters lower than they are today.
No one knows for sure why this cold age ended. What we do know for sure is, that humans couldn't possibly have been the reason.
Resonable climate change sceptics won't deny that humans influence the climate, they just say that human influence is tiny when compared to natural events.
Heat is always temporary, night time is always cooling, winter is always freezing and wild fires melt glaciers. 23.44 degree tilt determines/gaurantees that nothing can change unless we see a Volcano or Forest fire.
"No one knows for sure why this cold age ended."
*OF COURSE* we know! It's even in the video: Milancovitch cycles.
" they just say that human influence is tiny when compared to natural events"

one thing i would be very interested in though is how the temperature measurements are being taken, by whom, where, when. that’s probably what i’d look into first
@@GrowWithConrad Well, just look at the websites of the metereological services. They explain this in great detail.
I did the math with figures from 7:40 graphic, and if ALL of the energy were deposited in the atmosphere, and none in the soil or oceans, the air would have increased its temperature by 18 degrees celcius every decade. Thanks to high heat capacity of water for not letting that happen i guess...
By ALL of the energy i mean all of those extra net 0.6 Wm^-2 absorbed by earth, after the atmosphere and earth radiated so much of the suns heat away as they could.
whoops, update after reaching 20:24
Turns out Joe got 60 degrees and not 18... Well imma have to get back into the calculations tomorrow to see if I can spot any mistake in my calculations...
You did it by decade, and I believe his was "over all" so your numbers may not be that far off.
All (99.999...%) of the incident solar radiation is re-radiated. There is an energy balance. If it accumulates even a little, you would have far, far more of a temperature rise than what you calculate.

It's like saying I love you on the first date vs letting it naturally happen over a time of weeks and months.
Our system would not be regulated without freezing and freezing is something that cannot be stopped, that's how California had record braking snow two years in a row.
Listening to this video made me realize that why the planet is warming is irrelevant. It is warming and much to fast for the ecosystems to adjust. We face mass extinctions and if humans want to continue to live, we should do something about it (even if we would not have been responsible).
The fact that we are causing climate change means we are also able to get us out of that mess
Your comment makes no sense, you say that why the planet is warming is irrelevant. Then you say that we are causing it and means that we are able to get out of the mess. Then why is the source irrelevant? If it's mostly natural we have zero control.

What I am trying to say is: whatever the source of the warming is, it is warming and there is dangerous consequences to it and we have to do something if we want to survive. Even if it were natural, we should try to get out of this mess. The only thing knowing we are the cause do, is giving us (me at least) some hope that we have power over it. Much more than if we were not.
@@sourisdebibliotheque The reason why I think understanding past climate is relevant is that it shows the changes we are going through now is not new or unprecedented.

I don't think we have any real control over our climate though, we are along for the ride.

A few questions I am seeing in skeptic discussions, maybe you could help clear them out:
- What is the climate sensitivity for co2 or how much does earth warms upon a doubling of the co2 concentration in the atmosphere? What is this function? Is it a constant or it diminishes or increases depending the proportion of co2?
- What is the average time it takes for a full cycle of a photon depositing energy from the sun onto the surface and returning back to space as radiation given co2 at 0ppm vs higher concentrations like 500ppm?
1) they dont know
2) they dont know
What we do know is that the Earth is greening (more plants) as a result of the higher C02 levels, and we also know that plants are carbon capture mechanisms...
@@chrismcaulay7805 yes, that's a very good side effect of the co2 increasing. I think polution-wise co2 might be one the least problematic gases humans/animals emit given Earth's ecosystem.
@@chrismcaulay7805 what you are neglecting to take into account is that once co2 is in circulation it is in circulation until it is sequestered. The plants that may flourish under new conditions will eventually die and be eaten by bacteria and fungi that will release that carbon back to the athmosphere. Fossil fuels were created at a time when the athmosphere was toxic to species like ours AND when no organism was able to digest cellulose. This is no longer the case. All the carbon we free up is here to cycle through indefinitely.
The exact sensitivity to CO2 doubling isn't well pinned-down yet; it's usually quoted as 1.5-4.5oC or something like that. It's a big range, and a lot of people are trying to narrow it down. However, because of its narrow definition of "temperature increase at equilibrium due to doubling only CO2", there are circles in the community who don't find it super useful. There are many other GHGs besides CO2, and we certainly aren't emitting just CO2, and different regions will have their own sensitivity. Plus, as I think you're curious about, the sensitivity is definitely not constant over time. There are big arguments in the community over just how informative past climates might be in informing how future climates evolve. As a very simple example, an Earth that has massive ice caps will warm at a different rate than an Earth that doesn't have ice caps even if those two Earths absorb the same amount of energy. So it definitely changes, and it depends less on the amount of CO2 currently in the air and more on how much water is solid vs liquid, whether the most sunlight is falling on land vs ocean, things like that.
You second question isn't known, and it's not a well-defined question itself, though I think I know more what you're getting at. Since it's nearly impossible to trace any single quanta of energy through the Earth system to figure out exactly when that Joule "enters" or "leaves", it's much easier to discuss the rates at which energy is entering or leaving the system. Think of it like water entering a lake from a river and then later evaporating - it's almost impossible (though definitely easier than for energy quanta) to track a single water molecule as it enters and leaves, and the actual times you'll get will range from "almost immediately" for surface water that evaporates almost immediately to "almost never" if that water makes it way to the bottom of the lake and stays there. However, by comparing the rate that the river feeds the lake against the rate of evaporation, we can figure out whether the lake is growing o drying out. Same thing with energy - we can see right now that there's an imbalance of (I believe) roughly 1 W/m2 at the top of the atmosphere, which is contributing to warming. Back when our atmosphere was closer to 280ppm CO2 instead of the 400+ it was now, there was basically no imbalance at all. If we were to somehow drop to 0ppm CO2, we'd definitely get an imbalance the other way toward cooling.
@Chris McAulay Yes, Earth is greening as a response to rising CO2. But as long as Earth is greening, that means that CO2 is rising faster than the plants are capturing it. As someone else already pointed out, plants aren't a permanent solution anyway, plus as the Earth continues to warm, temperature and water stress will outweigh the CO2 fertilization effect. Basically, the "greening" is a natural response to anthropogenic effects, and as the video already discussed, natural effects are a drop int he bucket versus the anthropogenic ones.

Must pur on my climate scientist har for a moment. I saw the thumbnail. Climate change is natural. What isn't natural is the rate of change. The rate is unprecenteded. In the past, climate swings took thousands of years. We have managed to completely shift the climate in just a few hundred. The last big climate swing we caused was due to agriculture and even that took over 1000 years. That is why we are all worried. It is hard to understand how species can adapt to climate shifts when every other change they have endured took eons to occur.

We hear about "trigger points" all the time now a days. Since the last ice age, the glacial front has receded about 20 miles per year. As these glacial recede, they reveal darker masses underneath them. These darker masses absorb more heat than would have been reflected by the ice sheets. So, as more and more of these dark masses where revealed, did we hit a "trigger point" that accelerated the melting and allowed for more temperature absorption?
SittingInDetroit --- So, as more and more of these dark masses where revealed, did we hit a "trigger point" that accelerated the melting and allowed for more temperature absorption?
Wayne Patterson --- No. The Solar thermal energy resident within the Atmosphere is somewhere on the order of only about 17 percent of the Earth's gain in Solar energy. The vast majority of the Solar thermal gain is resident in the Hydrosphere and Cryosphere. Consequently, the currently small percentage change in the land surface albedo in the absence of the Cryosphere is relatively insignificant for the Earth as a whole.
SID: Tipping points (or trigger points as you call them) refer to situations where some kind of discontinuity is passed. The reduction in albedo due to loss of snow/ice cover (whether on land or sea) is certainly a positive feedback to warming, as you suggest, due to the reduction in the amount of incoming solar radiation that is reflected (harmlessly) back into space. (Wayne's comment doesn't make sense).
Trouble is we don't know with any great certainty when we might cross the various possible tipping points.
