no the answer is we don't know if we are already above 1.5c. It takes years to bend the Trend line up. So by the time it shows.. we are above 1.5 c. We will likely have been above it for years, and probably headed towards 2c
No doubt, there will be dumb responses from reality deniers quoting geophysicist Peter Ridd. He is not a coral expert or even an ocean ecologist. He is a shameless contrarian funded by billionaire Gina Rinehart and is not an ecologist. He frequently points to coral cover measurements as if they tell you everything about coral health and ecology. Terry Hughes and other coral scientists are a far more reliable source of information.
I’ve heard some people say they want to go on holiday to see the coral reefs before they’re gone. They rarely see the irony that they’re further adding to the cause of the corals’ demise in doing so (not that it matters too much at this stage, the writing’s on the wall).
as sad as it may be they are not wrong though. the reefs, esp. the natural ones we have will not survive. There is no indication that we will manage to limit the warming to 1,5 and even 2 degrees seem optimistic... the reefs will be gone be4 the ned of this century.
NASA’s predicting 2050 *or* *sooner.* It’s a running joke that all of this type of prediction are coming ‘sooner than expected.’ Personally, considering the rapid intensification of ocean warming in the last few years, i reckon reefs will be lucky to survive until 2035.
I haven't watched your videos for a while because, honestly, I'm finding ongoing climate change too depressing to even think about. It seems to me that while the environmentalists have good reason to despair, everyone else is becoming so very much more divided politically. Environmental concerns for the near future have become no more than 'minor annoyances' - while they have been given far more important things to think about. An old friend of mine is now enduring temperatures of 40 Celsius for the second time this year. Another fled her home for the coast when wildfires encroached last year (they missed, thank goodness, but it was close). And this is the thing, so msny more of us are either getting caught up in extreme weather events, or personally know other people who have...and 'still' nowhere near enough is being done. It's almost like our politicians are trying to distract us from pressuring them to act by throwing even more immediate problems at us. Usually, I buy in a load of trees to plant over the Winter season. Have done every year for decades. Can't afford it this year. Everything's just far too expensive. Earlier this week, I looked over my little bit of land at partly finished planting projects and I wondered if it is worth carrying on any more.
I understand those feelings Debbie - the topic can be so overwhelming. what's important to remember is that there are so many shades of gray. while things like coral reefs are incredibly vulnerable, many aspects of the climate system (like insects - as I mentioned) get worse and worse as we continue heating. but the flip side is every bit of heating, every bit of warming we can avoid makes things better and is worth us doing. so as scary as things are, please don't give up making this world a more beautiful, safer place. p.s. I found making this video particularly depressing, and I'm going to make a particularly positive one next to offset it. stay tuned!
Deep-water corals exist in colder regions, for example, near the coast of Norway, the UK, France, and Portugal. They suffer from deep-water trawling (30-50% of reefs in Norway). And thanks for another wonderful video, Adam
A work around could be preserving coral reefs in tanks until we can restore them in the future. I hope it doesn't come to this, but if we preserve them now in tanks the option will be available in the future.
Electric Reefs seem to be very useful In my country (sorry, but if you want to know more, Indonesia also does them) it was used to preserve huge parts of our coral Reefs which we subsist on
I looked into doing this because I have an aquarium but the electricity cost to run UV lamps was extremely expensive. Also corals need very stable water parameters so you need to use a lot of water changes to maintain the minerals. You could still test your water regularly using a lab testing subscription that should save the water changes. Another issue I’ve seen happen to some reef UA-camrs was that their coral died during power cuts. Either from the heat, the cold or the lack of oxygen!
@@jbmurphy4 Truth... Long term Coral preservation in tanks is exceedingly problematic. We're just not on any realistic pace to save even part of this phyla or the 30% of species that rely upon it.
I can't remember the details, but there is a project based out of the IUI (I think it was the IUI) in Eilat, Israel that has been specifically working to identify heat tolerant coral species from reefs in the Gulf of Aqaba, which as a region has naturally endured big temperature swings, being an enclosed, effectively tideless bay locked in by extreme desert environments. The coral species there were found to be exceptionally tough, and there is an idea of using these corals as pioneer species on degraded reefs around the world to help kick-start their recovery. It's controversial and I must admit I'm personally very much in two hearts about it. I'm from Aus, and the plight of the GBR absolutely tears my heart to shreds, but I just don't feel deliberately introducing an invasive species specifically selected for it's survival ability is a good idea. It could very easily displace our own native coral species that it is meant to help restore, and we wind up with a denuded monocultural reef unable to host the complex symbiosis our reef is based on as the source of it's vitality and abundance. Instead, I feel we should be doing this work outselves in Australia, finding potential pioneers that already exists here on our reefs that we know can integrate well into a wider Pacific reef ecosystem. The reefs of our northern coast around Darwin are poorly studied, but are well adapted to extreme heat variations, as well as stressors such as big swings in salinity, depth, turbidity and nutrient loading from being in a mega-tidal environment, with strong moonsoonal influences suddenly dumping huge amounts of fresh, nutrient rich, sediment heavy waters from the rivers onto the reefs. These northern reefs need to be understood, as to some extent they are already living in the dystopian future we are trying to hard to bring about for ourselves.
In cretaceous time reef existed under much hotter sea wather. they were biologically different at least in part and their adaptability to such high temperature is simply due to the fact that they edapted trough millions of years not a century!. We continue to live and consume as everithing was normal, we continue to think 1.5 c can still be reached while we have surpassed it and going for the double, we still be greenwashing about net zero, carbon credit and CCS etc. In tuscany in the meantime a buoy in open sea is measuring surface temp around 30 c....
Coral reefs can't move north or south if ports are in the way, they can't survive in turbulent waters....we get in the way, we love to build near the sea, so we block off viable areas.
Slow groving corals can take decades to even begin to cover their losses. 400 years of growth can be killed in a single bleaching event. 50% or more has been already lost, not only in Great barrier reef, but from all warm water corals. Few yeara between bleaching events means corals have no time to recover or even spawn new coral animals. Often repeated 2C warming treshold is currently high likely crossed while trend is even higher 3-5C. 2.4C in the pipeline with current emissions and we keep on adding more (Hansen). These rapid temperature shifts, that we are causing, will kill all corals. 500 million are directly dependant from coral reefs as their food source. Indirectly number grows to 1-2 billion. These people will need food, so after reefs are gone, they will consume land based foods. This will ramp up prices and make hunger more likely across the world. Fossil burning is not only rising temperatures, but also making seas more acidic. This affects the calsium bodies that makes the reefs making situation even worse. Ocean ph has dropped rapidly in recent decades. In my books reefs are already dead. Living dead.
They might move to colder waters leaving the dead white riffs behind. No not the corals on the reefs. they might start a new reef from eggs somewhere else. There are deepwater reefs too. We will see big changes though.
It is a greater threat than a world war event but we can't get the world to pull in one direction because the enemy is us and our way of life. Too many are unwilling to compromise or give up their luxuries.
In last 3 million years temperatures has not breached 2C before. That timeline is when Earth is somewhat the same as today (continents, mountains, chemistry, climate...). (See what Rockström says) We are accelerating out from predictable future with extreme warming rates that human made emissions creates.

"We should have had been doing..." They are soooo beautiful - and provides fish for 2 Billion ppl. You'll have war - if coral reefs die out. Sugar talk doesn't help?
Another great video Adam... but. I think you're opening and message will resonant keenly with those who already have some understanding of the changing climate and are looking to understand more. Presumably, for example, ships are routed through the GBR because it is cheaper (or maybe its because the more direct route will reduce emissions?). Even if only cheaper in the short term or because external costs aren't factored in, this left me wondering if a narrative that focused more on the human impact of losing corrals could better motivate change?
@@christianrobertdemassy900 The high sea temperatures in 2023 pretty much wiped out the corals in Florida. I am ashamed that these beautiful habitats will not be viewed by future generations. I fell in love with reefs since they are life in 3D. You can be totally surrounded by schools of fish and amazing diversity.
@@TimpanistMoth_AyKayEllthe rate of change is based off temp data that was manufactured, not natural. There's been real temp chang during last 13 thousand years, but it's certainly not happening now. They trick people the same way stock market scammers do
We will lose essentially all coral. But we'll keep samples alive and eventually.... 1.5 is here. We could quibble about the next El Nino and right-now's base temp, but would you take a bet that the next 20 years will average under 1.5? Yesterday doesn't matter. In fact, past performance sucks at predicting future results if trajectory isn't part of the visual. We mere humans need a visual about the immediate future climate and by conventional rule of thumb "climate" is 20 years. Besides, knowing yesterday's weather is as helpful as knowing yesterday's winning lottery numbers. Thumbs up
I'm not a huge fan of geoengineering for the climate, but how about geoengineering to save ecosystems, for example giant pumps (using offshore wind energy) to pump cooler seawater from the open ocean over coral reefs to keep them cool (in conjunction with the currents) or cooling ocean seawater on land and pumping it over the corals (using clean energy). In "closed" seas (eg Red Sea) this may be more challenging as deeper cooler ocean seawater is further away
@@DrSmooth2000 For MCB to work there must be clouds present. Pumping cool water over a reef during marine heatwaves (or something similar) wouldn't rely on anything else being present.
At this point, growing awareness is a great thing to do. Hopefully, people will realise the impact of our choices and steer away from the crisis we're causing.
What survives climate change are those species that either have a very wide variability or out reproduce the speed of change. Do the polyps of the coral reefs fit either?
I first heard about climate crisis killing tropical coral reefs at 1C maybe a couple decades ago. Looks like we decided 'who cares about reefs', the quip at the British conference of that time.
The _overall_ warming - if defined as the average over an ENSO cycle - hasn't reached 1.5°C quite yet, but will likely do so within the end of this decade.
We have already lost over 50% of knsect biomass... And that does not end to the insects, but we have lost around 50% of the very life from Earth. (84% is plants, so we have lost mostly trees...)
Yeah, I just watched a video by Kyle Hill about the insect extinction. It had not dawned on me but when he mentioned road trips and your cars used to be plastered with bugs it gave me pause. I had just driven from Phoenix to Denver and back and it is true.
thank you, it will change soon, there are other source of energy that with international cooperation in coastline, we can reduce global warming, sea is huge source of energy, further more we can prevent these phenomena like cyclone and flood and wildfire by using this hot seasonal atmospheric condition, recent years in summer, geothermal energy happens in surface of coastline, there are many countries in coastline with seasonal hot weather and water condition, in sum-up, by using this energy not only is economical but also reduce global warming in countries like Japan, China, India, Mediterranean countries, Iran, Mexico, Us, Canada, (Africa and Arabian countries....) . I invented new method base on air pressure rules and quantum physics ionization sea water minerals in strong dynamic magnet and electrical field and electric chemical reactions as part of fuel for producing electricity and fresh water and fertilizer. 7 zero pollution methods for reducing global warming I mentioned in my profile.
Perhaps you can understand when I say the oceans are lost to us, as it is not just global warming doing it. It isn't ocean acidification either. Acidification would do it, but the thing that kills the oceans is our hunger for protein sources. We will fish out the oceans by 2035. Industrial fishing will be over. It will be hard to find areas not affected by deoxygenation or acidification at that point. Traditional fisheries will have collapsed. I think total collapse of sea food resources was set for 2048. So, first we must find a way to replace the amount of protein we extract yearly with something grown. We have to solve the issues of excess nitrogen and phosphorus leaching into waterways. Find ways to reverse ocean acidification. And I don't think we have the first clue on how to do any of those things. I would live to be wrong! Please tell my I am wrong! If I am correct, or even off by a bit, the point is... the oceans are done. It can be a powerful thing to accept reality. It informs you on what things are possible. If the oceans can not be saved, then we can go all "mad chemist" and find ways to use the oceans to fight global warming. We really need to get our heads screwed on straight. We need traction on the temperature gauge. Just restraining the continual slow warming is not enough. We will have to pull it back a ways too. We need the oceans...
Nuance at every level can't say for sure how fish are because no one knows or it is classified Lot of money if knew where and when and what species to catch 》 Nitrogen and phosphorus are needed but need to be spread out. River delta dead zones are not climate dependent except longer algae growing season Mixed data on ocean greening as more plankton fill the seas 🧜♀️
@DrSmooth2000 one of those nuances would be cycles of flooding that erodes waterways exposing toxins that are buried along waterways, including farm run off. I have heard that we are trying to apply smaller amounts of fertilizers instead of overdoing it as we are now. However, more pressure to produce plant proteins exposes more land to fertilizer use. If we are to reduce livestock consumption, we have to replace that too. As atmospheric CO2 rises, our produce grows bigger, but nutritional value goes down. Protein values go down with higher CO2 values as well. The oceans become over populated by plankton and jellyfish the further out we look. There is lots of alge growth going on in fresh water lakes now, that will continue to increase as waters warm up. The warning was to keep global temperatures from going over +1.5°C for those reasons.
@@monkeyfist.348 comment won't fully open so just reply to runoff. ▪︎ yah, runoff sux. Manure or synthetic fertilizer wasted and irreplaceable top soil is going. Big fan of hydro dams but unfeasible on the biggest rivers. Nutrient and soil is caught for possible future reclamation from heavy metals PFOAS pseudoestrogens microplastic (emits methane.

On ocean side... Marine geoengineering looks like a bust but theory & demos has potential for Eco-engineering. Some time lag but Could learn to manipulate currents and get that sediment to surface Great for plankton and sea protein... bad for Climate. Carbon back up to air interface
Need to do a video on OTEC tech. Very clever, Jules Verne idea originally. Has dangers. Wait and Sea, as it were 🦭, stand back and stand by. Arctic Ocean is going nuts with productivity already with little warmer and more runoff... each area is unique in some ways. Wrt protein itself... never thought about it. Nitrogen is fixed on land via lightning... not be the same?
Perhaps a good course of study for people who are frightened would be the Geology of Reef Systems or the Geology of Carbonate Systems (or any similarly named course). You'll find that coral reefs, coral atolls, and coral islands are built on top of a few thousand meters of dead coral. If they didn't die, these structures wouldn't exist. On top of that, they're not invincible. They have a lifespan just like every other creature. And it's not just the coral polyp, but the algae, the bacteria and the other organisms inside the coral biome. None of them are invincible. They die at some point. On top of all that, coral reefs like the Great Barrier reef are constantly getting showered by copper sulfate and zinc sulfate from seafloor volcanic activity to the east. Both are none too healthy for corals. ( Zinc oxide isn't healthy either.) And, as anyone who's studied the subject knows, sea water is always saturated or supersaturated with sulfates. But this is the environment they live in. And this is going to ruffle some feathers, but contrary to current mythology, the climate actually changed many many times prior to 1870. Most of the time quite rapidly. We have proof of it.
It's not the end of Reefs. They will just become weaker and more susceptible to damage and certain species of Coral will likely die off. There have been Coral Reefs for 160 million years. This includes periods of much higher ocean temperatures and acidification You can do coral reef studies from long ago by examining the fossil records.
The problem isn't (just) the temperature. It's how fast the temperature is changing, and we're seeing it's hugely out pacing the rate at which corals can adapt or reefs can shift.
@@ClimateAdam Perhaps a good read for you would be Sudden Climate Transitions During the Quaternary. I don't agree with its assessment on greenhouse gases, but there's way too much evidence in the geologic record that indicates climate moves rapidly as a general rule. As for GHGs, the physics that one runs into commonly are all wrong. Most GHGs at current levels only MAINTAIN some energy in the atmosphere. They're limited out, so adding a higher percentage of them does nothing. That's not to say we should continue to pour them into the atmosphere, we should remove what we put in. However, the Doom and Gloom and Fear narratives are anti-productive.
@@ClimateAdam to some extent, but not entirely true. What is happening is one species of coral symbiont algae is slowly replacing a less heat tolerant one but it will take a very long time for the more heat tolerant algae species to cause the area to recover because it reproduces and grows at a much slower rate than the current dominate variety of less thermal tolerant algae
@@JimmyD806did occur to me a while back that it fits if CO2 retains heat 🛡and methane rapid cycle is what 🤺 jabs up. Vegetative forcing creeps up to solidify gains over ice.
and when I say very long time I mean multiple human life times and lots of species of fish and crustaceans will also go extinct in during this transition.
So reefs are like clothing, you should avoid hot water and bleaching to keep the colors. Well with the cost of living nowadays, can't afford to raise the environment bill too!

@@DrSmooth2000 For MCB to work there must be clouds present. Pumping cool water over a reef during marine heatwaves (or something similar) wouldn't rely on anything else being present.
@@CitiesForTheFuture2030 also less problematic as precursors to SAI
However the energy to pump water is massive.

Love your videos! Very informative. Thank you!
well thank you for watching and commenting Jennifer!
0:11 guess you meant to say an end to the vitally important things they do for the natural and human world. Otherwise GREAT video
Great reporting as ever. Adam, any chance you could do a piece on the latest AMOC collapse scientific papers?
It's a topic I'd like to return to for sure, but honestly it's not that long since my last amoc vid!
@@ClimateAdampapers were pretty weak and one entirely mathematical
Rebel faction at Potsdam did a paper denouncing tipping points if want drama 🍿
Hi Dr. Adam!
hello!
No way
That was you?
At this point, growing awareness is a great thing to do. Hopefully, people will realise the impact of our choices and steer away from the crisis we're causing.
Welcome Climates!!!
CliMates to the rescue!
What survives climate change are those species that either have a very wide variability or out reproduce the speed of change.
Do the polyps of the coral reefs fit either?
Are those 'soft corals'?
how much time is left for our extinction in your opinion?
It's funny. These doom prophets used to preach from crates in the town square. Now they're monetized on UA-cam. Hahaha!!
Human extinction? Probably not within ten thousand years in all but the most outlandishly catastrophic climate scenarios.
@@General12thunder 150ppm in next glaciation could do it
Coral reefs are amazing.
I first heard about climate crisis killing tropical coral reefs at 1C maybe a couple decades ago. Looks like we decided 'who cares about reefs', the quip at the British conference of that time.
Glad mentioned breeding and seeding them. Once we stabilize GW, the Red Sea strains hsve Hot genetics 🧜♀️
Rebuild then
I'm interested in understanding how David Ridd comes up with an opinion that seems at odds to the information you provide.
We need to develop more coalitions of the willing - collaboration climate-change warriors, collaboration.
Hi Adam, I hope you get some house plants soon. ❤
I've got a couple - but my current flat layout doesn't make sense to film in front of them... yet!

Time to start a plant based diet
We’ve been at 1.5 for the last 13 months.
100% - but that's not how the limit is defined. watch the vid linked to at the end!
The _overall_ warming - if defined as the average over an ENSO cycle - hasn't reached 1.5°C quite yet, but will likely do so within the end of this decade.
I would love to think that coral reefs will be here for my grandchildren
but unless we stop CO2 emissions, they will not.
it's such a horrible thought..
We have already lost over 50% of knsect biomass...
And that does not end to the insects, but we have lost around 50% of the very life from Earth. (84% is plants, so we have lost mostly trees...)
Yeah, I just watched a video by Kyle Hill about the insect extinction. It had not dawned on me but when he mentioned road trips and your cars used to be plastered with bugs it gave me pause. I had just driven from Phoenix to Denver and back and it is true.
It's the end of everything.
No. Bank’em.

thank you, it will change soon, there are other source of energy that with international cooperation in coastline, we can reduce global warming, sea is huge source of energy, further more we can prevent these phenomena like cyclone and flood and wildfire by using this hot seasonal atmospheric condition, recent years in summer, geothermal energy happens in surface of coastline, there are many countries in coastline with seasonal hot weather and water condition, in sum-up, by using this energy not only is economical but also reduce global warming in countries like Japan, China, India, Mediterranean countries, Iran, Mexico, Us, Canada, (Africa and Arabian countries....) . I invented new method base on air pressure rules and quantum physics ionization sea water minerals in strong dynamic magnet and electrical field and electric chemical reactions as part of fuel for producing electricity and fresh water and fertilizer. 7 zero pollution methods for reducing global warming I mentioned in my profile.
Perhaps you can understand when I say the oceans are lost to us, as it is not just global warming doing it. It isn't ocean acidification either. Acidification would do it, but the thing that kills the oceans is our hunger for protein sources. We will fish out the oceans by 2035. Industrial fishing will be over. It will be hard to find areas not affected by deoxygenation or acidification at that point. Traditional fisheries will have collapsed. I think total collapse of sea food resources was set for 2048.
So, first we must find a way to replace the amount of protein we extract yearly with something grown. We have to solve the issues of excess nitrogen and phosphorus leaching into waterways. Find ways to reverse ocean acidification. And I don't think we have the first clue on how to do any of those things.
I would live to be wrong!
Please tell my I am wrong!
If I am correct, or even off by a bit, the point is... the oceans are done. It can be a powerful thing to accept reality. It informs you on what things are possible. If the oceans can not be saved, then we can go all "mad chemist" and find ways to use the oceans to fight global warming.
We really need to get our heads screwed on straight. We need traction on the temperature gauge. Just restraining the continual slow warming is not enough. We will have to pull it back a ways too. We need the oceans...
Nuance at every level
can't say for sure how fish are because no one knows or it is classified
Lot of money if knew where and when and what species to catch
》
Nitrogen and phosphorus are needed but need to be spread out. River delta dead zones are not climate dependent except longer algae growing season
Mixed data on ocean greening as more plankton fill the seas
🧜♀️
@DrSmooth2000 one of those nuances would be cycles of flooding that erodes waterways exposing toxins that are buried along waterways, including farm run off.
I have heard that we are trying to apply smaller amounts of fertilizers instead of overdoing it as we are now. However, more pressure to produce plant proteins exposes more land to fertilizer use. If we are to reduce livestock consumption, we have to replace that too. As atmospheric CO2 rises, our produce grows bigger, but nutritional value goes down. Protein values go down with higher CO2 values as well.
The oceans become over populated by plankton and jellyfish the further out we look. There is lots of alge growth going on in fresh water lakes now, that will continue to increase as waters warm up.
The warning was to keep global temperatures from going over +1.5°C for those reasons.
@@monkeyfist.348 comment won't fully open so just reply to runoff.
▪︎ yah, runoff sux. Manure or synthetic fertilizer wasted and irreplaceable top soil is going. Big fan of hydro dams but unfeasible on the biggest rivers. Nutrient and soil is caught for possible future reclamation from heavy metals PFOAS pseudoestrogens microplastic (emits methane. More climate sensitive to send fast and deep into sea as you can so aerobics digest it)
Leave the ocean into Discourse of beavers and Soil & Water Conservation Districts. People trying their best there already so Don't expect much more Action.

On ocean side...
Marine geoengineering looks like a bust but theory & demos has potential for Eco-engineering. Some time lag but Could learn to manipulate currents and get that sediment to surface
Great for plankton and sea protein... bad for Climate. Carbon back up to air interface
Need to do a video on OTEC tech. Very clever, Jules Verne idea originally. Has dangers.
Wait and Sea, as it were 🦭, stand back and stand by.
Arctic Ocean is going nuts with productivity already with little warmer and more runoff... each area is unique in some ways.
Wrt protein itself... never thought about it. Nitrogen is fixed on land via lightning... not be the same?

More taxes and real pollution please ! Sign me up lol
Perhaps a good course of study for people who are frightened would be the Geology of Reef Systems or the Geology of Carbonate Systems (or any similarly named course). You'll find that coral reefs, coral atolls, and coral islands are built on top of a few thousand meters of dead coral. If they didn't die, these structures wouldn't exist. On top of that, they're not invincible. They have a lifespan just like every other creature. And it's not just the coral polyp, but the algae, the bacteria and the other organisms inside the coral biome. None of them are invincible. They die at some point.
On top of all that, coral reefs like the Great Barrier reef are constantly getting showered by copper sulfate and zinc sulfate from seafloor volcanic activity to the east. Both are none too healthy for corals. ( Zinc oxide isn't healthy either.) And, as anyone who's studied the subject knows, sea water is always saturated or supersaturated with sulfates. But this is the environment they live in.
And this is going to ruffle some feathers, but contrary to current mythology, the climate actually changed many many times prior to 1870. Most of the time quite rapidly. We have proof of it.
There's no sign that 2023 qualifies as "freakishly hot" -looking a lot more like an acceleration.
It's not the end of Reefs. They will just become weaker and more susceptible to damage and certain species of Coral will likely die off. There have been Coral Reefs for 160 million years. This includes periods of much higher ocean temperatures and acidification You can do coral reef studies from long ago by examining the fossil records.
The problem isn't (just) the temperature. It's how fast the temperature is changing, and we're seeing it's hugely out pacing the rate at which corals can adapt or reefs can shift.
@@ClimateAdam
Perhaps a good read for you would be Sudden Climate Transitions During the Quaternary. I don't agree with its assessment on greenhouse gases, but there's way too much evidence in the geologic record that indicates climate moves rapidly as a general rule.
As for GHGs, the physics that one runs into commonly are all wrong. Most GHGs at current levels only MAINTAIN some energy in the atmosphere. They're limited out, so adding a higher percentage of them does nothing. That's not to say we should continue to pour them into the atmosphere, we should remove what we put in. However, the Doom and Gloom and Fear narratives are anti-productive.
@@ClimateAdam to some extent, but not entirely true. What is happening is one species of coral symbiont algae is slowly replacing a less heat tolerant one but it will take a very long time for the more heat tolerant algae species to cause the area to recover because it reproduces and grows at a much slower rate than the current dominate variety of less thermal tolerant algae
@@JimmyD806did occur to me a while back that it fits if CO2 retains heat 🛡and methane rapid cycle is what 🤺 jabs up. Vegetative forcing creeps up to solidify gains over ice.
and when I say very long time I mean multiple human life times and lots of species of fish and crustaceans will also go extinct in during this transition.
So reefs are like clothing, you should avoid hot water and bleaching to keep the colors. Well with the cost of living nowadays, can't afford to raise the environment bill too!
