My favorite way to go to sleep, gently lullabied by his lilting voice telling us of our future horrors. Yet it’s not nightmare fuel. That’s talent. He’s like the Bob Ross of science.
You will love PBS space time then. Dr. Matt’s voice is like molasses
Bob Ross made different and unique art. Not regurgitated information
All science is regurgitated information
@avo616 I believe the comparison has to deal with the mood , vibe that they both give out and put the audience in.
I find it terrible for sleep, cause it's too interesting. I need to watch these multiples times for them to become proper lullabies later on.
Are you serious? I was just browsing for a video to watch along my meal, refresh and what do I see? An almost 2 hour Astrum video posted a minute ago. Thanks man!
Edit: What exactly in my comment makes disappointingly many people assume that I eat for 2 hours straight? You people do comprehend, that a video can be continued being watched after one has finished eating, no?
Right? The timing is perfect!
Having a late breakfast. 🥰
Same here except 26 minutes ago.
Be thankful it's not the like 24 hours video he posted last month. Heh...
Eat up.
I don't think I've ever learned more about weather in 2 hrs. If not for the all mighty astrum I'd have zoned out. Truly fascinating
This is the best summarization of the climate I've seen. It's rare I see the solar cycle discussed to the point of nucleation sites. I wish you had discussed the long-term brightening of our sun (models vary, but scientists estimate the sun was 30% dimmer during the time of the dinosaurs than today), as well as vulcanism.
Regardless, this is the most comprehensive video I've seen and I wish more people would see it. I know I'll be sharing it with people.
Thank you for the kind words and for supporting the channel!
Weren't there also really old stories that suggested at one point the earth was in perpetual twilight, and that something happened at some point in the distant past, that made the sun way brighter and hotter? I can't recall WHERE I heard that story, just that it had something to do with "the mystery schools" and some knowledge passed down within. Very interesting though - and something I find entirely plausible.
For some reason the censors won`t allow me to type this number, but it`s FIVE-THIRTY-SIX, the year, and it was the beginning of a terrible period of suffering due to vulcanism. Sulphur compound spikes are present in ice at both poles. Today it would be far worse since we`re completely unprepared which is hard to believe. This relatively stable temperature period for the past 5000 years will abruptly end one day. Our corn, wheat, rice, beans and fruits won`t be able to be produced and livestock won`t be fed. And no preparations are in place to ease the fall. That isn`t very smart and it`s baffling.
@@baneverything5580 536, did it work?
@@baneverything5580wouldn't the sulfur indicate massive volcanic eruptions?
1816 The global "Year without summer (big freeze)" 3°C temperature drop and crop failures. April 1815, volcano Mount Tambora began to violently erupt. Millions of tons of ash, dust, and sulfur dioxide were released into the atmosphere, casting a temporary chill across the planet as it Blocked out the Sunlight for months on end. Documented around the world in literature.
What goes up must come down!
Our atmospheric filtration system is one of the best around!
This narrator is so good at speach and oration, "I" actually look forward to learning.
Dear Astrum team
I want to congratulate you on this beautiful production of almost two hours on the discussion of global warming.
The extensive scientific research that you addressed and delved into is simply brilliant.
Bravo !!!
I am a Geologist and yes, climate change is scary, but through this documentary, you manage to bring the true and essential substrate necessary for us to understand the relevance and responsibility of our role as human beings within this complex cycle that has governed our planet for more than 4 billion years.
Continue to improve knowledge of astronomy and science in general with your videos.
Once again, congratulations to everyone on the team and especially to you, Alex McColgan, for the wonderful work leading your Astrum.
It's not that scary
@@tetrasphere8165 yeah it is. This last week has been unbelievable. It’s so frightening so many people have died so many people lost their homes. If you don’t think that’s frightening then you might be a sociopath.
@@Jude74 I've worked for 4+ environmental groups but the fear is ridiculous. Being afraid of car farts and cow farts is silly. Respect the earth regardless and just keep in mind that on the day we get our so called footprint down to near zero, is the day a volcano blots out the sun. Also our technology will catch up before we have to start shitting our pants.
I would bet my doctrate that you are not the sharpest pick in the case.
Our planet was formed 4 billion years ago according to the new scientists carbon dated. But it took almost 3 billion to transform from big ball field with ocean of magma, slowly cooled down due to excessive CO², Sulphur Dioxide, emitted through the empty space filled with vacuum and push it while creating our atmosphere millions of average meteorite continue to bombard the earth from far solar system due to new created solar that introduce new gravitational energy. Our earth after covered with gases emitted from lava ball covered the earth surfaces and reduce the solar heat then our earth started cooling leaving behind solid compact but delicate mineral while the chemical reaction that gives the sun it's energy continue to burn and melting irons plate and leave stone behind to form the different types of solid spread crust. and the process never stopped till today. The earth have experience 3 ice age in 4 billion. Our earth still have another 2 billion years of enjoying life as it cycling around the sun.

Crafted by AI ?
this video feels very natural and quite well written, plus this channel has been producing videos on a similar quality for years, so despite the growth of AI in the past year, i really doubt it
@@Skyymon don't bother, conspiracy nuts will conspiracy.
No thank you ( as a blanket solution). We need some transparency as to what is already being manipulated, by who and why. No the real why!
Let me help you to look at it differently. One volcano eruption is equal to all human influences for one year. So if the solar magnetic energy is being absorbed in the earths core that causes more volcanic activity and we get 4-5 more per year one can understand the co2 rise. Imho climate change is real but humanity isn’t as big as a factor as the globalist claim. The globalist have used cc to give them authority. They have plans to control every aspect of your life. 15 minute cities, control food supply, digital money that can be controlled. Eventually they will require you join the system or die. They will require you to worship them. A global money, a global government, a global religion. And eventually a chip underneath your skin that can control your money, your health, and eventually your thoughts. Transhumanism. They have told us the future and most on here will call me a conspiracy theorist. Most ignore the facts that de population has already begun. Put your trust in the creator. Read more. Find the truth. Cc is real but the globalist are using it to bring in globalism. I suggest following a UA-cam channel called suspicious observers. He reports on cc and many studies that don’t get public attention. Peace to all and love each other.
@@Gotprivacy-noyoudontwhy do people believe someone very powerful can alter and manipulate the nature? The only power so powerful that can alter the natural process of our earth is the same force that commanded all the energy to act together colliding on each other to cause friction to ignite highly explosive energy that left debris burning Ashes and gases into the space and everything works precisely to form what we see today. Only that power can command the same forces not to work again. The biggest thing we human can build to life on earth is nuclear and hydrogen bombs. 😂😂😂
Watching from Rajasthan

Dude!!!! Do you have underground lifestyles? Wild
What's extra frightening is that such a huge proportion of the world's population, and still growing, is living right in the path of that temperature increase.
@@justinjones5281 "Just turn on the air conditioning!"
The idiot response I used to get from architects back in the '70s in response to clearly badly designed major buildings.
@@peterbreis5407 "... huge proportion of the world's population, and still growing, is living right in the path of that temperature increase."
That should tell you that humans like the warmth and not the cold.
@@pulsar22Not the kind of warmth that kills you though which is what's happening in india & asia right now & it's come early too
Solar cycles also affect the polar vortex. Solar maximums put more energy into the atmosphere causing increases in the variability of the polar vortexes. At solar minimums the polar vortexes are basically circular.
Solar cycles have also been linked to the magnetic connections between the earth and saturn.
Magnetic connections between the sun and planets is at least as important as the gravitaional connections.
Also affecting the heliosphere is the cyclical connections with galactic influences.
Good job. Well put together discusion.
Some would say gravity & magnetism are one in the same.
Amazing video! Had to watch it in parts because it is so long, but did'nt want to miss anything. Thank you for researching all the facts for us and let us know cleary what is assumption and opinion, and what is not. Favorite part was 'Context is important'!
“It won’t likely be something that ends human civilization all together” those odds don’t give me much comfort 😅
So in 10 or so years a spring tide with an onshore storm surge will deffo break records in loads of places .
Thank you once again, Alex. Your documentaries are excellent and so instructive. They always bring us good information.
Amazing job! One of your best videos yet!!! Thank you!!!
The is figging excellent. Thank you Alex. I have learned so much about each of these cycles and how they interplay. Some stuff I knew, some I thought I knew. But this has been truly educational.
Great video, thank you!
I knew about the existence of many of these cycles, but it is nice to see them all compiled in one work and also described in such depth.
I was thinking the same thing. I knew about literally everything in the video, but he goes into so much more detail... the devil is in the details... :) This was done quite well! I was going to post the same thing you did.. lol but you beat me to it :)
I just love how Astrum pronounces ”earth”. It’s like ”örth”, the sound that the Swedish letter ö makes, if a bit more nasal.
It's a south Welsh vowel sound I believe
Sometime I hear accents so pronounced they sound like a foreign language. No such problem here, I can understand nearly every accent originating from the British isles.
So he pronounces wrong then
No he pronounces it correctly for his part of Britain.
@@jimwilson946 He has a very annoyingly affected accent. I've never quite worked out what kind of accent he is trying to suppress. I thought he was Irish but does sound it.
Love the vid! These long ones really get me chilled out. I wondered if you'd do a video about the giant solar flairs we've recently had, showing the arura. Seeing one from the UK was pretty amazing. I would love to understand what the solar flairs are, what they mean and the effects they have on us and space around us.
Really nicely done!
I live in Rio Grande do Sul, Brazil, we are experiencing an extreme Flood even bigger than the one in Peru like you showed, and it was partially because of the El Niño as well, the power of the elements in our earth are insurmoutable, we can't really predict or overcome them right now, and yet we influence it so much
Things that make you go hmmmmmm
É terrível o que estamos vivendo aqui. Sem precedentes na história e, mesmo assim, nem mesmo outros brasileiros parecem entender a dimensão do desastre.
The cosmic rays coming through the souther anomaly could be creating more rain, I have read that cosmic rays couse cloud nucleation; not sure how stronge the evidence is though.
Grass is taking over the earth. These days it seems like I have to mow every single week, if not twice sometimes. I'm consumed by my ideology of the rise of grass.
Do we influence is so much though? Man covers almost none of the Earth. Our Energy usage and output is not even near even that of a mid size storm yet our Egos leave us to believe its all our fault. Its literally Tea leaves for modern man. Looking for meaning in any place we can for that we cant control or understand.
The more I've learned about our power grid & our climate, the more i realize that modern nuclear energy is our best option. LFTRs, Thorium Reactors, molten salt reactors, etc. Utilizing our advanced technology, Improved engineering & material science. Utilizing our greater understanding of safety & well made designs. We have so much more advanced computer technology & robotics that can be used. It feels like even tho tons of advancement has occurred with engineering designs, safety measures, etc. It still doesn't matter to most people. It's like most people are ingrained with a natural negative response when talking about nuclear energy. It's a bummer because i truly believe that our best option for our future is to start utilizing Modern advanced nuclear energy options in our electrical grid. It's just proving to be challenging to get politicians to get on board.
It will really allow places to be much more energy independent. Less reliant on fossil fuels. They'll have efficient, stable electrical grids and the rest of the grid could experiment with alternative power sources, power desalination plants, etc.
We need to heal from the trauma of our past. See & learn that those things only happened solely from Us not understanding what we were doing when it came to nuclear energy at the time. We didn't have advanced enough technology, material science, engineering, safety measures, understanding of how to go about everything, etc. This source of energy will greatly help the world improve towards the future and lowering emissions. More than anything else could, while also providing a very stable electrical grid system. Currently we have alternative energy options but the majority of our grid is powered off of fossil fuels and emission producing sources of energy. We will be so much better going forward commiting to modern advanced nuclear energy options.
It's been very irritating that our society has taken this "Change is up to you" approach. It just takes advantage of people's emotions. This climate issue is so much bigger than any one individual. This needs to be an across the board kind of thing. That's the only way we might make the Slightest difference. We've already waited too long. Everyday is a day wasted. A day where we haven't committed to modern nuclear energy options. Where we haven't even started building it. It should be utilized in collaboration with other alternative energy sources all over the place. This power source is the best option to improve our environment & will really help lower our emissions. The only thing holding us back is legislation, fear mongering & past trauma that's affected us from our past failures (which is understandable but I know we can do better now. We've learned so much sense then. We gotta give it a shot. It's such a beneficial energy source when done right)
Did they outlaw electricity, oil, natural gas or coal when things went wrong in the early days of those fields? No! They kept going and understood things usually are bumpy and difficult in the beginning and kept going even tho those sources negatively impacted our environment. A huge issue is our government is BLOCKING any sort of progression from happening. Will be lucky to see the slightest projects approved or finished with-in the next 100 years.. It's very annoying to see how much we have gotten in our own way when it comes to improving or advancing certain things. Instead we let fear, money, man made "required legal processes" Stop us from doing anything other than wind, solar, oil, natural gas, damming our rivers, mining for minerals... It's very frustrating because we should be able to use all these options in collaboration. If we actually wanted to improve anything. That's what we need to do and stop letting so much potential get blocked from ever occurring in the first place.. It's really irritating. I wish certain people didn't make this so "complicated and difficult" Why would any reasonable person want to block progression?
Because they are making billions selling oil...
There are some good thoughts in here. Something for you to consider: What parts of this are driven by your own emotions, and what emotions are they?
Over time science and business have come up with ever-increasing ways of being stupid and greedy. We have had: lead pigmented paint, leaded gasoline, dioxin from imperfect manufacturing, phthalate in plastic, asbestos, etc etc Microplastics may be killing us all. Without regulations we'd all be dead by now and most birds would be extinct
@@TheBcoolGuy are you implying his initial point that we should utilize nuclear is moot because the rest of his post is full of idealism and the realization of how fucked the world is? Strip the discussion of emotions, and look at it pragmatically, and nuclear is the much better option. ANd im not talking about those reactors built in the 50's. Im talking current designs like OP mentioned. Breeder reactors are undeniably one of the best ways to generate energy, with minimal human input, and tiny carbon footprint. Its about as automated as you can get with energy generation, hence why nuclear is so damn cheap. Not to mention, the literal only waste is STEAM. Coal is also more radioactive than even current nuclear reactors, which is WILD to me, considering the biggest argument against nuclear is the radiation.
Please keep comments to one or two sentences. Geez.
Alex your videos are always top notch and this one is right up there with the best of them!
Dude! Next level content, so so good. Thanks man.👌🏽✨🌌

You're like me. BUT, read ths : When I described on a social platform what do I do to relex, (I'd say learn the world around me) the answer I got was kind of "Gesus Christ, what would you be watching if you were worried"

@@Kelnx I found out in last 50y of my life that people think it has to do something with intelligence, but I think bullying people or disrespecting them without deeper thinking of its consequences does have something to do with intelligence tho , or maybe just little bit
im disappointed the opener didnt say that all of the data is based on a sample size of 1. Still waiting on another water laden planet with a moon in the goldey locks zone with no more than a 2% mass variance and similar star age. for it to be a control sample it would have to have 0 technological development.

Awesome documentary, riveting from start to end.
Thank you for going into deep detail to explain this to people. Hopefully they'll start listening now that they've got a more complete rundown of the science.
If a nuclear war starts tomorrow, the climate debate is meaningless. According to Milankovitch, the atmosphere is very gentle and sensitive to many influences and it needed a long time to support life. Greetings from Serbia.

What an incredible and comprehensive video to explain how our climate works and how we are affecting it. Thank you for this gift. This is a real gem. BRAVO!
At first I've clicked without looking at the length of the video, thinking it would be like 20 min or so. I usually look at your videos during my breakfast 😁 (thank God it's Saturday, though 😅) . When I've reached the Polar Vortex chapter, I've thought to look at the length, thinking this is way over 20 min ... and, boy, was I surprised! 🙂 Thanks a lot for your video! Impressive work! I've really enjoyed it! 👌
Great work :) Thank you!
Excellent presentation, thank you..
The approximate 50 actively erupting volcanoes spewing CO2 and SO2 into the air certainly helps with greenhouse gases. Tonga's volcano sent steam amounting to 63000 olympic size pools int the Stratosphere. I wonder how our footprint measures up.
Well, the "scientists" are now saying volcanoes have no effect at all...regardless of size or number. Amazing, eh? History is being erased at a record pace.
I'd like to know this too
It's not even measurable... There's actually been a downward trend over the last several hundred years of CO2 concentration in the atmosphere... It's currently at 0.04%... plant life dies entirely at 0.02%... once it drops below 0.03%, certain types of photosynthesis cease to exist.
Climate change exists, but the entire idea that humanity caused it, is nothing more than a fraud to wring money out of people... And have them willingly support it!
Our footprint doesn't even begin to touch volcanoes...... One single volcano eruption like Tonga can release 100 years worth of CO2 if it was created by humans. And as you've noted there are always MANY volcanoes spewing CO2 into the atmosphere every single day of the year.
That's why the entire thing is a scam. It is nothing but a ploy for power, money, and control. We can all literally end our lives as we know them and start living a truly CO2 NetZero life for every single human on the planet and it wouldn't make a difference if one single supervolcano goes off in the next 10,000 years....... And that's not even including all of the regular volcano activity.....
Brilliant video. This needs to be shared with EVERYBODY.
fantastic, really enjoyed this!
Wow, what a comprehensive review of all relevant cycles influencing our climate. Excellent work
I’m super happy Astrum put out this 1hr almost 2 video thanks for that I am like many others intrigued by your content as I find it to be informative and calming I learn a lot about space from you and other channels kinda similar like Fraser Kane, PBS Space Time and others for more education thanks again bro!!!
Excellent, I am glad someone has best use of their intelligence to pit all aspects into a more profound way of describing where everyone else is afraid to go.
Will come back for the rest. 29 minutes in and very good ! 😊
it would be nice to talk a bit also about pollution and not just about CO2...great video anyway thanks!
It would be nice if he talk much about the massive deforestation of our designated rainforest for timbers and land clearance to accommodate industrial grazing ranches. And what is the impact of this action and the chain of reaction of tempering with massive ecosystem? Could our life survive the imbalances of ecosystem. Amazon is now cleared to create ranches and boost Brazil economy. I hope the new government is now regulating and recovered the lands grabbed and illegal acquired by the former president elites.
How about the last two years of solar x-flares (some of the biggest on record) and the increased volcanic activities?
Lolz that is the funny thing about this guy
Zero info or data or explanation of why we have such insane rapid warming. He just kind of glosses over that and says that this is some more advanced thing and right in the beginning he basically tells everyone watching that you're a moron and you should delete whatever you know so that his subsequent 1.9 hours of time completely installs into your brain and replaces whatever you thought before.
@@mansoormannix1753
Yes indeed deforestation, however not so sure if our species' impact on Earth's land has been any more devastating than the oceans, or our atmosphere? if you consider the size of things.
Australian here
The delay or otherwise of our monsoon has zero to do with our bushfires. These can happen on any and all years but are
u s u a l l y worse on el nino years as the south of the continent experiences temperatures in the high 40's to low 50's in these weather patterns receives little or no rain in summer except the wettest la nina year (when the monsoons come 2,000km further south). We even get bushfires in dry southern winters but they are far mor easily contained. Discounting the la nina years (about 1 in 20) where the monsoons come far south our summer rainfaill is consistently very low except the east coast. In el nino years our winters become unusually dry and this coupled with extreme summer heat from constant high pressure cells causes our most massive bushfires.
Edit. 2020 was the tailend of a three year elnino. I know the the northern hemisphere claims the el nino occurs in their summer, but it occurs around christmas - the Australian summer. By our winter the el nino had passed as had the bushfires...
Many of our fires are fire bugs unfortunately
Absolutely awesome video.
Thank you.🙏
Nice that you said 'nearly' but a refresh was nice. thanks
Now I know what "The winter is coming" really means
6:40 FYI at this part(so far in your video) is incorrect. Paradoxically Earth is warmer when it is farther from the Sun. This is due to the seasonal effect of the uneven distribution of land and water between the northern and southern hemispheres.
July, when Earth is at its most distant, is also summer for the northern hemisphere. The north has more land which heats faster than water. January, when Earth is closest to the Sun, is summer for the southern hemisphere dominated by oceans which respond more slowly to the increase in the Sun’s energy.
The tilt in Earth’s axis produces almost 20 times the effect of the changing distance from the Sun, and the difference in local geography is 2 to 3 times more important than the changing distance.
We make our closest approach to the Sun (147.5 million km) in January, that's called perihelion, and we're farthest from the Sun (152.6 million km) in July, that's aphelion.
"Averaged over the globe, sunlight falling on Earth in July (aphelion) is indeed about 7% less intense than it is in January (perihelion)." That's the good news. The bad news is it's still hot. "In fact the average temperature of Earth at aphelion is about 4° F (2.3° C) higher than it is at perihelion." Earth is actually warmer when we're farther from the Sun!
How can that be? It's because our planet is --in a sense-- lopsided. Continents and oceans aren't distributed evenly around the globe. There's more land in the northern hemisphere and more water in the south. During the month of July --near the start of northern summer-- the land-crowded northern half of our planet is tilted toward the Sun. "Earth's temperature (averaged over the entire globe) is slightly higher in July because the Sun is shining down on all that land, which heats up rather easily," says Spencer.
Solar heating raises the temperature of continents more than water because the heat capacity of land is lower. Bill Patzert, an oceanographer at NASA's Jet Propulsion Laboratory explains: "The temperature of land changes easily, which is what we mean by low heat capacity. Consider the desert: At night the desert is cold, perhaps only 60° F. When the Sun rises in the morning the temperature might jump to 100° F or more." Such mercurial behavior is characteristic of materials like rocks and soil with little thermal inertia. It doesn't take much sunlight to substantially elevate their temperature.
"On the other hand," says Patzert, "oceans have a tremendous heat capacity. They tend to keep [the energy] they capture and are very stingy about giving it back." This quality moderates the temperature swings of ocean environments. "Let's say you went sailing off Malibu Beach at noon," says Patzert. "The offshore temperature might be 75° F -- pretty pleasant!" What happens after sunset? "The temperature drops, but only a few degrees because the thermal inertia of the ocean is so high."
All this explains why July is our planet's warmest month: Northern continents baked by the aphelion Sun elevate the average temperature of the entire globe. Six months later, in January, the situation is reversed as our planet presents its water-dominated hemisphere to the Sun. "We're closer to the Sun in January," says Spencer, "but the extra sunlight gets spread throughout the oceans." Southern summer in January (perihelion) is therefore cooler than northern summer in July (aphelion). Strange but true!
Another notable difference between summers in the two hemispheres is their duration," adds Lebo. According to Kepler's 2nd Law, planets move more slowly at aphelion than they do at perihelion. As a result, Northern summer on Earth is 2 to 3 days longer than southern summer -- which gives the Sun even more time to bake the northern continents.[1]
The fact that people living in the northern hemisphere are warmer when near aphelion is primarily due to the seasons, which are caused by the tilt of our axis. The fact that the Earth as a whole is also warmer when near aphelion is due to the difference in geography between the two hemispheres (mostly water in southern hemisphere, water and land in the northern hemisphere). In numerical terms, the tilt of our axis produces almost 20 times the effect of our changing distance from the Sun, and the difference in local geography is 2 to 3 times more important than the changing distance.
TL;DR: Earth's land is not evenly distributed and the thermal inertia and heat capacity of the Oceans is different than that of land, plus a bunch of other factors. Basically we're out of phase with what you'd expect based on the distance alone.
Your analysis is correct but so is the presenter's - he doesn't contest the actual overall temperature effect on the earth, and correctly shows that it is changing. Northern hemisphere gets milder summers compared to southern - that's fact.

Correct me if I'm wrong, but with regard to the alleged sudden relatively large increase in temperature since 1850, attributed to human activity... is it not true that climate heralds have adjusted temperature records downwards for the intervening period in order to give the impression of a significantly and steadily increasing average temperature?
In reality, when considering the unadulterated data, the overall increase has not been around 1 degree, but only a fraction of that AND this comes with a margin of error that could even nullify any apparent increase (or conversely double it, but still below a whole degree).
In addition to this, we have the phenomenon of encroachment of development upon weather station sites - we all know about urban heat islands (where towns and cities tend to be warmer than the surrounding countryside). This then causes affected weather stations to register an increase of average temperature over time. The distribution of weather stations is increasingly urbanised, so temperature records are going to appear to increase.
The role of CO2 as a greenhouse gas is seriously overstated - the contribution of this trace gas is in the order of hundredths of a degree, in contrast to the effect of atmospheric water vapour, which raises Earth's average surface temperature by 15 degrees. Even if all of the atmospheric CO2 increase in the last couple of hundred years were to be attributed to human activity, mankind's contribution to the warming effect would still only be hundredths of a degree.
As for rising sea levels, I only have to think of Al Gore's predictions to see the mockery. Very low-lying parts of the world were supposed to have disappeared beneath the waves by now, but the Inconvenient Truth is that they haven't done so. Unquestionably sea levels do rise and fall, typically over fairly long periods of time (during glaciations and interglacial periods) and certainly slowly enough for people to barely notice over the span of a lifetime. I wouldn't worry. Similarly, I wouldn't worry about an approaching glaciation which is likely to occur over the next several thousand years - mankind (and life on earth) will probably adapt to whatever happens.
Some sources will report the temperature anomaly vs. pre-industrial levels, while others will report it versus a more recent baseline (e.g. 1950-1980). That's why some of the temperature increases might seem smaller and some of the historical levels might seem adjusted downwards on some plots. However, if you look at the delta between any two years on any of these plots, you're going to get about the same result. As the video correctly states, we know the average global temperature with a high degree of accuracy and have for most of the industrial age. There is consensus among scientists that the planet is warming quickly, and that this warming is primarily being caused by humans burning fossil fuels. This is not an urban heat island effect. It's not like scientists have only been taking time series with raw thermometer readings from the planet's cities. We can get temperature via satellite nowadays. And besides, it's just not reasonable to attribute global warming, which there is scientific consensus on, to incompetence in data collection and processing.
The temperature anomalies that have been recorded aren't even close to falling within the margin of error. Error bars are in the neighborhood of 0.03 to 0.04 degrees C depending on the data set you're referencing. The anomalies are on the order of 1.3 degrees C versus pre-industrial levels. Please do go look up the data yourself, or just skip to 1:48:34 for a montage; they present the data in a few useful ways.
I don't know where you're getting your information about CO2, but you're misinformed. Over the past several hundred thousand years, average global temperature and atmospheric CO2 concentration have been tightly coupled. Prior to the industrial revolution, atmospheric CO2 had bounced between about 180 and 280 ppm, with 280 representing a mild period and 180 representing an ice age. We're over 420 ppm now, and going up by close to 3 ppm every year. Water vapor is technically a stronger greenhouse gas than CO2, but it doesn't stay in the atmosphere nearly as long. So, while atmosphere water vapor is certainly a positive feedback on global warming (warmer planet -> more atmospheric water vapor -> warmer planet), that isn't the reason for global warming. The cause is primarily carbon emissions, which is why reducing carbon emissions is the primary focus when trying to address the problem. Its impact is demonstrably much higher than hundredths of a degree, as it is responsible for the majority of the ~1.3 degree C increase we've seen vs. pre-industrial levels, and its tight coupling with temperature farther back in Earth's history. Refer as well to the video, which cited the evolution of plants and cyanobacteria, both of which exchange atmospheric CO2 for O2, as potential causes of massive historical drops in global temperatures.
Sea level rise is on the order of 20 cm versus pre-industrial levels. However, the net effect is more pronounced in many coastal cities, as they tend to be sinking, in part due to groundwater pumping and the weight of the buildings. The warmer atmosphere also results in stronger storms, which causes enhanced coastal erosion and worsened flooding. The rate of sea level rise is increasing as well, in part because it's a positive feedback loop (warming oceans -> ice melt -> less energy reflected back into space -> more ice melt), and in part because human CO2 emissions have never been higher (all of our efforts thus far have only slowed the rate of increase; emissions are still growing steadily higher). All of these factors have combined to hammer coastal communities, as predicted. I don't know who was claiming Florida would literally be underwater by now, but that was never a realistic expectation. However, if all land-based ice were to melt, global sea levels would rise on the order of 100 meters (see 1:48:58), and global warming is much more intense in polar regions (see again, 1:48:34; look at the anomalies around the poles that have built up in recent years).
Just saving this comment to read later
Excellent summation. Thank you.
Unfortunately everything eventually gets politicised and funding is the only reliable barometer
The so-called consensus among scientists is nonsense - it is a consensus of mostly people who don't understand properly and are along for the activist ride, plus people like Gore who simply wanted to make a fortune out of fleecing people with scary messages. The activist voice is very prominent and this threatens academic funding for those who speak up in favour of objectivity, so some voices are silenced and people forced to tow the activist line to keep their funding. As for rising sea levels, check out the Maldives and also ask why so many wealthy people choose to live right at the water's edge. Do they know something the activists don't? By the by, when ice caps melt, the land beneath often springs up as the weight comes off and sea ice melting has zero sea level effect. The Antarctic maximum seasonal sea ice extent has been at record levels in recent years, according to NASA satellite monitoring (since 1971).

The world seems to constantly get deeper the closer you look. Even in the most simple areas of life. So I beleive if I dont pursue being an expert in it I should just give "my" current stance to the most nuanced and detailed explaination Ive heard. They have shown the most evidence for the deepest knowledge on the topic.
Thank you for making this. Im sure, as with everything, even more nuance exists... there always is... even in the most simple seeming areas of life.
Well yeah, we live in a universe that's almost infinite, and each one of us has our own small universe inside our skulls....
Nothing is simple
An infinite Mandelbrot set of knowledge and detail. We can just keep zooming in.. or zooming out.
I really like this content and video specifically, I found it very informative. One minor note, when reffering and showing the current magnetic poles you show and talk about the north magnetic pole and the geographical north of the earth. Currently the south magnetic pole is in the northern geographic hemisphere. The red north of a compass is attracted to the earth's south magnetic pole.
I can't get over it gets colder the closer earth gets to the sun, that just makes no sense, for it to be winter then. Crazy world
Hey Alex, are you writing all this, editing the video etc just by yourself? Impressive work ❤
When you start speaking about CO2 at around 12:30, why are you showing nuclear cooling towers which emit no CO2? We need more nuclear power, not less, so please do not associate that with carbon emissions.
Because this channel propagates the climate change myth
@@Punished_Trump We still need more nuclear power, not less. But irrational climate wackos don't like nuclear either I suppose.
@@Punished_Trumpit’s not a myth, it’s happening, what’s debatable is just how much we effect it and what the actual issues are that arise from it.
@@Punished_Trump hurrrr durr
@@KelticTimclimate change is always happening, but climate change in daily parlance is referring to the Anthropogenic Global Warming hypothesis. That is 100% debatable, especially the "solutions" we see put forth to a problem that can't be proven.
All I see is poverty forced on people for a problem that only exists in computer models.
Thank you for your considerable effort.
A fascinating read is Dave Lowe's 'The Alarmist' and his work with Charles Keeling (of the 'Keeling Curve'). Dave worked out how to measure the chemical composition of the atmosphere (more difficult than it sounds) and from there they were able to confirm the human contribution to the rising greenhouse gas levels - 50 years ago!
I like a lot. Thank you for your hard effort to make this Masterpiece.

He went along with man made CO2 causing global warming which is totally untrue & is just one gigantic hoax.
I hoped for the same and ended up being really disappointed by the end of a 2 hrs long video. He repeated 100% mainstream narrative. Which I would be fine with, but what was cunning was the clickbaity title pulling in people to watch 2 hrs of exactly 0 controversy.
I've see lots of info about how in the 70s the climate change people were warning about an ice age.
My theory is that they created things that would purposely warm the planet and it worked a little too well and now we're dealing with those consequences.
I'm sure if we had enough mirrored surfaces deployed strategicly across our lands, we could reflect enough sunlight to reverse the climate mess that these people possibly created.
But that would be too simple.
@@old_gaffer The "mainstream narrative" is based on the scientific data described in the video. These facts have been known to scientists for decades before it became mainstream knowledge.
@@ermpson5799 and no one here is arguing that. I pointed out the fact that the original title of the video was "my most controversial video on YT...." and there was no controversy whatsoever in it. so don't get triggered for no reason.
