If we come together all 7.8 billion stop all emissions. We still melt a guess about 85 % all ice and permafrost. Not to mention the shock this planet would have.
I remember hearing that there is an enormous lag time between green house gas emission and its full effect. The Perma-frost is thawing now but today’s emissions won’t be fully fealt for 10-20 years. My mind thinks we have already passed the tipping point.
There was a PNAS study on the tipping points that concluded that THE tipping point triggering all the other ones was somewhere between +1.5 and +2°C... So we are def close but IF we put strict regulations there is still a chance to reach a stabilized climate (hotter but at least somewhat stable) edit: The PNAS study was on hothouse earth: "Trajectories of the Earth System in the Anthropocene" Vol. 115 | No. 33

@@josephstalin5003 Humans have a much bigger threat than Climate Change. We are WAY overdue for a solar catastrophe. And our magnetic field is failing FAST.
To be honest: it’s hard to be optimistic after understanding this explanation. If methane is such a potent greenhouse gas and its release can only be slowed by reinstating permafrost conditions in the arctic… well, we’d better get to work on survival strategies for a significantly different world, even more extreme than the 2 degree change models. 😅
@@rdallas81 agreed in the “never again by flood, next time fire” way of thinking… makes me curious to know what atmospheric changes triggered that ancient apocalypse, I expect it’d be similar to our realization about methane release today. or, did you have a different “destined” in mind with your comment?
@@grantandre79 I absolutely believe a fire end to the world. Burnt up completely in fervent heat so hot that even very subatomic particles that comprise atoms and molecules will be burned up just like space itself- big rip or the increasing speed of space itself will outpace the ability of material to withstand it.
I have seen calculations on 10.2°C warming by european foresight group John Doyle on average, that will be much higher on the continents, if that is true even bacteria will not survive, forget about survival, nobody and nothing will survive this
I’ll be honest, as someone who’s worked on this, once we get to 2 degrees, we arrive at 4 really quite quickly. Once we’re in a 4 degree world, we need all the energy we can get. Taking the 4 degrees of warming aerosols are hiding into account, we’re sat on a +8C time bomb, and we need to figure out how to defuse it on a bigger scale and more quickly than we’ve ever done before
We will experience a lot of positive feedback loops and all the linear intervention strategies like 3% annual reduction based on a reference date will fail.
Why does the environmental crowd never mention the largest single release of methane in the history of the world done when the US blew up the Nordstream 2 pipeline recently?
Then who is funding it then and what are their goals, he cherry picks his data just like all the so called climate experts. T This is also debunkable like all the other vids.

I don't blame people for being skeptical of the self serving politicians and this economic system that prioritizes the interests of the already very wealthy. I just wish it was easier to convince them that climate change is not some ploy for them to control more (they're clearly not competent enough to do that), but is something happening outside of human civilization and is due to our rapid progress and we need to wake up and recognize that if we're not careful, we'll be an example of "intelligent" life being too self destructive to last very long.
I am just trying to learn all I can…often your “thinks” are over my head, but I try! And I admire how your break down such enormously complex topics to educate less science savvy people who, nonetheless, are determined to learn what we can to help. I’m glad I subscribed. Now I’m going to check out that Reuters animation.
There was a reaserch team in siberia who found large lakes filled with methane Bubbles their concern was that if these bubbles were to be released at once they would be dangerous to the environment and they had detected that there was a seriously high level when this methane was released Yet nothing was said about this no blame it on us and cow's burping people are making big money out of this the truth is out there
As you noticed. By using biogas on an industrial scale. Sewage, Farmwaste, Food waste you could take a gigantic amount of methane gas out of circulation. Sustainable as well, but governments supports only wind and solar. That is one of the main reasons I don't support their vision of climate change. Because they are not serious. All is about money, your money.
Been a lot of volcanic eruptions the past 2 years...Volcanoes put out alot of methane...unless I missed it...I didn't hear this mentioned as a variable. I've been keeping an eye on things like earthquakes, solar flares, and volcanoes since 2010 and the past 2 years have seen some particularly large volcanic eruptions...and also some terrible fires...California had some very bad wild fires in 2019...and 2020, wild fires in Europe around 2020-2021...and let's not forget something like half of Australia caught fire...at one point there were huge fires on just about every continent...excluding Antarctica. So massive fires burning millions of square acres across the globe and some huge volcanic eruptions it doesn't seem altogether surprising from my vantage point that methane would be on the increase.
I saw a study recently about how beavers are moving north and creating more lakes in the high latitudes in Canada and Alaska and how that is accelerating the release of methane. Every new report is just another brick in the wall.
I was there, the beavers have always been there, we were discussing buying mass areas of land and removing the beavers to create grasslands for animal hay feed.
I had to do a presentation on gas hydrates when I was in college, ironically about it's prospects as 'fuel source'. Just reading for one section about it's challenges for extraction itself gave me unimaginable level of climate anxiety ever since and made me realize just how reckless the petroleum industry is for spending money for marine prospecting expeditions for gas hydrates even when they know full well that one small mistake can set off an unimaginable level of catastrophy for our planet; one 'oil spill' equivalent for a gas hydrate extraction process is enough and more for a catastrophy. Gas hydrates are already under the threat of destabilizing with just global warming and the petroleum industry still want a piece of that pie
Dear Dave, I think I have watched every one of your videos for at least two years, but methane levels alarm me so much, that I'm going to give this one a miss. 10 years ago I would reliably get at least a week and probably two of continuous sub zero temperatures, and so much snow I got fed up with it. But the last 5 or so years just rain, and occasionally a bit of slushy snow for a few days. It has happened so quickly that my youngest child has quite different experiences of winter than my oldest. This can't be caused by CO2, which causes slow change, but could very plausibly be caused by methane, and as you've mentioned before, the Siberian permafrost is melting,and that is terrifying. Thank you for your untiring work, your thorough research and perceptive presentation. I find we as humankind are running headlong into the abyss, and far too few people seem bothered.
I know personal annecdotes dont mean much but I'm also expiriencing one of the warmest winter when there were sub zero temperatures a few years ago. Truly terrifying to think what summer might be holding in store for us in 2023.
You forgot to mention 2 other sources of methane being released into our atmosphere. The first is the unchecked release of CH4 over decades from hundreds of old oil pumps in western Texas and the second being the methane explosions leaving gaping holes in Siberia and Alaska, the first recording of this phenomena was in 2014. Neither of these are part of current climate models.
Methane is present in almost immeasurably low levels and in the last 50 years the amount has increased by a tiny fraction of immeasurable levels. You are talking parts per billion when measuring a gas that breaks down naturally to mostly water and some C02. Climate alarmism is big business. Isn't it time you stop funding adversaries because you got easily frightened?
@@richardivonen3564 No, the fear creation is accelerating. They need you to stampede. Again. Remember trust the science re: Covid? How did that work out? Stop trusting these people!
9:00 one small thing. I need to see with my own eyes how an arctic lake (not seawater) can be prevented from freezing. That's an unbelievable claim. I grew up at only a 45 degree latitude in Canada. Ice forms on all water surfaces in winter, even in waterfalls, and it is thick.
Don’t forget the methane from rapid permafrost melt. Ice sheets melt from under the water releasing ancient carbon dioxide and methane as well as belching volcanic activity in Iceland and all its wonder oceanic faults that are recharging and erupting in the Atlantic Ocean floor!
Dave it's always a joy to watch your flawless execution in the transfer of this new and changing knowledge (making it much easier to understand) while on a deeply troubling subject. Keep up the great and essential work.
Dave is mostly dellusional and anthropocentric... Not even a climate scholar (economist). Yeah he reports the science correctly, albeit selectively... But hopelessly comitted to a favourable (positive) outcome. Which of course is now irrelevant.
@@andrewblake2254 One man's mad idea is as good as the next mans. Let the dreamers dream - just don't expect the taxpayers to pay for their foolishness.
I think you'll find that the reason for the climate is the sun. We are not warming up. The southern hemisphere has seen record cold, the northern hemisphere has seen record cold. The northern hemisphere has seen record snow cover. Greenland has gained ice above the 30 year average month on month. The polar bears are not near extintion. The barrier reef is in the best shape ever. The North and southern magnetic poles are moving at an incredible rate, as the magnetosphere (protecting the earth) weaken. We have reached the turning point. This winter will be long. The climate will gradually cool year on year. The weather will become more extreme. Co2 accounts for 0.074 % of of the atmosphere and man is responsible for 3% of that. 3% of 0.074 % will not heat anything. So perhaps you could just have a think. Al gore told us the ice caps would be gone by the summer of 2003 and in the winter by 2013. And lastly, can you provide the papers pier reviewed that directly link man's activity to global warming. The Romans grew grapes in Scotland? When did global warming start?
@@petewright4640 Do we know that? It chucked a load of water vapour into the stratosphere which I would expect to have a warning effect, but interested to hear your view
In my personal experience i have observed that methane generally lingers no more than five or so minutes depending on the size and filtration of a given area. Discovering the source however can be quite difficult at times especially in small enclosed high population areas such as planes, elevators, board rooms etc. Barring of course an audible release, I generally use as a rule of thumb, "He who smelt it dealt it!" This atmospheric anomaly can sometimes be quickly neutralized by striking a match without all the fuss of government regulation.
It displaces oxygen and doesn’t dissipate quickly, it just sits there at just above ground level. On top of methane hydrates from frozen deposits defrosting rapidly… And lp pipelines have vents that are open to the air and just vent mostly methane. And other things found in fossil fuels. Unfortunately these pipes are often right next to population centers … Fracking. Is horrible and releases methane too
I am not a scientist. But waht i basically get from this is that methane gas has always been here (i believe in Creation bt Yahova, not evolution - so that part i undeestand). Man made pollution has altered our ecosystem to something not "normal" / natural. Now that we are trying to reduce man made pollution, the natural order of things is going back to "normal," which is messing with the abnormal that we have grown accustom to. We want it both ways. We want our world the way we want it to be (which is no natural), but do not accept that once we take away man's effect on nature, it is not what we want. It's warmer. It's wetter. Nature will "invade areas WE want to inhabit. If we let nature take its course, WE will have to adjust. We cannot make nature adjust to mankind.
All this proves is that nature is KING and it doesn't matter what we do it's going to do what it wants to do. As a species we have almost no effect on what's happening.
I am still to see a methan molecule. Over 30 years I have been hearing about the Ozone depleting and it still haven't changed it's still depleting amazing how it haven't come to an end.
Methane, natural gas, is an energy source. This methane pouring out of the melting permafrost, since we have no way to capture gasses on a global scale and if we did we wouldn’t have a problem, will warm the atmosphere 84X more effectively than CO2. Water vapor, steam, is another greenhouse gas we already use as an energy source.
The implication of this observation is that we are tackling climate change in the wrong order - we should be focusing first on methane reduction by moving to a global vegan world to reduce atmospheric methane and release land that can sequester CO2, and THEN focus on reducing fossil fuels.
OMG! This isn't news to me, however, I haven't heard any updates on this concern for quite a while. TY for sharing... Will stay tuned and support anything i/we can do to slow it down and turned it around... If there's even any chance to do so we need competent leadership locally and beyond. Just saying... 🙂
I'm so glad that I'm old, and have no offsprings. 😖😥 I am so, so sad for young people now, and for future generations. If they really will evolve. I sadly believe humanity is dying in the time of only decades.😭
Mee thane (said through your nose) exists in the atmosphere at 1.7 parts per million. CO2 is 400ppm. It also has a very short life because it quickly oxidizes and breaks down. (self regulating)
An excellent report, so I've subscribed. What interest's me is the effect of DIRECT heat production into the atmosphere, such as heated air in urban conurbations from computers, home heaters, fridges, air conditioning units, cooking stoves and car engines. I think scientists are not including this sufficiently in their models and are grossly underestimating it, which is why their models and predictions always seem to be wrong and lagging behind what is actually happening in global warming. Reducing emissions is good, of course. But switching cars to electricity is not going to reduce the direct heat production of the engine - electric cars get just as hot as petrol ones. This heat is dispersed directly into the atmosphere, and as it is produced at ground level this heat may take some time before it is radiated away into outer space. A report by JHAT on how much such heat is being generated and how quickly it is radiated away would be very interesting indeed.
I remember the full shutdown, of course I still had to take packages to the post office, which I do by bicycle with or without a trailer depending on how much I have to carry. The air was so clean! I could smell that some grass had been mowed hours before. I could smell peoples' cooking. It was really peaceful. I also got much more cautious and even paranoid about traffic, though, as while there were far fewer drivers, those few were a lot crazier and indeed, traffic deaths for drivers and pedestrians went up markedly in my city in 2020.
It makes total sense... The people who DID follow the lock-down were more likely to be law abiding, careful citizens. The people who completely ignored it, we're much more likely to be conspiracy theorists, criminals, drug users, or simply people who take risks and thats why You encountered what you encountered. Not surprising at all, really.
@@extropiantranshuman Unfortunately, it wasnt just the reckless people who were killed by covid. It also killed many others that were cautious, stayed home as much as was possible, wore masks, got vaccinated, and followed the lock down as closely as was possible. I wore my mask, followed the protocol, stayed home for months, and I caught the virus on the one day I left my house to go and get my first vaccination shot. Go figure, that's just my luck.. 🤷🏻
@@davelowets actually that's why I didn't get a shot - because I felt taht people were going to get ill waiting in those lines. I felt it was reckless. I'm not here to judge you but that's what I thought then - that vaccines were a perceived sense of safety and that if you stay away from people your chance of getting the virus is 0. I stayed home and didn't get it. For 2 whole years. Thanks for confirming my suspicions. I'm just saying being cautious doesn't make up for the times you're not. I mean you can say I avoided committing a crime for many years until taht one day. Like how does that change anything?
I live in Australia and this summer has been the coolest I've ever felt....personally i feel that the covid lock downs definitely cooled the place down... I guess everyone staying at home eating all day elevated methane levels lol 😆
I believe there is a simple answer... So many people during lockdown turned to cooking various different foods to keep their minds occupied, they ate all this food and the resultant increase in flatulence resulted in this spike.
Because when people are worried, they eat different and produce gas. Tell the world to stay at home for 2 weeks, then another 2 weeks, then another 2 weeks, then another 2 weeks, then another 2 weeks, then another 2 weeks, then another 2 weeks, then another 2 weeks, then another 2 weeks, then another 2 weeks, then another 2 weeks, then another 2 weeks, then another 2 weeks, then another 2 weeks, then another 2 weeks, then another 2 weeks, then another 2 weeks, then another 2 weeks, then another 2 weeks, and stuff like this will happen.
Very well put together videos and dialogue. I appreciate how you left humans out of the problem and pointed out the naturally occurring cycles of warming and cooling of the Earth much like climate control HVAC system in your home, it has a few degree variance.
So reducing the pollution produced by our civilization (which seems to be the greatest aim of today's governments) actually accelerates the process of global warming? And if we could take our civilization back a few hundred years -thus reduce human-caused pollution, it wouldn't change much from a global perspective? Is it because the damage has already been done and there is no way back from where we are now OR maybe human influence has never been that important, as it is a natural change in the life of the planet and if we were still living in mud huts this process could go even faster?
How about the concentration levels of methane? Might be 28 times more potent but concentration levels are in PPB while CO2 in PPM So all this increase doesn’t do much
The problem is when you look at the a absorption spectra of greenhouse gases, you see that water vapour is a much larger contributor to global warming than methane or CO2, and a large part of the wavelengths that CO2 absorbs overlap with water vapour, on the other hand all of the wavelengths that methane absorb are also absorbed by water vapour.
Heat absorption goes up in direct proportion to dropping temperature. For example, ice water absorbs more heat than 10 degree celsius water. The greenhouse effect therefore contains a huge contradiction to thermal physics, because the hypothesis says the opposite: that temperature increases with increasing heat absorption.
Haha oh now. Well frankly, we have bigger issues. Following models that cannot possibly reflect an accurate picture of reality is not the thing we should be doing
Anyone would imagine that from this evidence (just as an example) that the climate system is a lot, lot more complex than currently described in the global circulation models. Another issue is the amount of methane emanating from the Nord stream pipeline explosion. Surely the gases emanating from the ocean can be mapped and quantified - I have not seen one scientific paper from the global climate scientific community on this topic - hmmm I wonder why?
So just to confirm what you have concluded. Polluted city areas were warmer as dimming effect was reduced... hence wet land warmed up... BRILLIANT!!! Especially that we know CH4 is mainly released from mid Africa... Glacier termination event perhaps as usual?
You explain that the gases heat up the atmosphere due to the photons returning back bla bla bla..., and just after You say that the pouted air was the reason for the areas that had the most pouted air had the climate temperature lower because of the pollution. This sounds like a absurdly contradiction to me
Why can't they stop driving car's and only let Government,Doctor's Lawyer's and Hospital's,the Council ect very important place's drive car's, and let the rest go on push bike's, maybe that might help a lot more out too.
This is exactly why you should never trust anyone that says ‘the science is settled’. They’re either a fool that doesn’t understand science, or are trying to manipulate you and bully you into conforming. Every time we make an assertion, nee evidence emerges 3 months later that contradicts our blind assertion that was based on models of the previously settled science. More humility is needed and we need to recognise that we do not completely understand the complex relationships within our atmosphere and oceans yet. Our interventions often do more harm than good in the long run.
Also fire can purify the air of methane and other combustible gases in the air. This is part of the reason why wood fires are actually healthy for the planets atmosphere.
So what is all this extra methane going to do to global temperatures?Have we reached a tipping point now so that even if we ditched fossil fuels tomorrow temps will keep rising regardless?Have we already destroyed the habitability of our planet for future generations?
Let's face the common sense! If we don't pump it out of the ground it will find another way! Just because we quit using it it doesn't mean the earth will stop producing it so where will it go? Just common sense!!!
What caused major swings in the ice temperatures over the last 4,000 years in Greenland, especially over the last 150 years, off the coldest temperature levels. It seems that temperatures eventually move to the mean over time. If that is so then what we have seen over the last 150 years is just mother nature moving back to the mean average.
It'll be fine, FINE, everything's totally fine. We don't have 2x the frozen methane and starting from 1/2 their bade, making the real rate of change closer to 20x.
It seems like every time it snows some person who should know better says, "See, global warming isn't real". We shouldn't push our luck with this. The consequences are too dire.
Gaseous methane can be converted to liquid methanol fuels. Whilst not a perfectly clean energy solution, it would ease demand for crude oil based automotive fuel and be a less polluting alternative to petrol & diesel. The increases in naturally occurring arctic permafrost methane could also be tapped for widespread gas-powered electricity generation plants, although this may change the geopolitical balances of power toward nations with large permafrost methane resources, such as Canada and Russia.
Apparently the Mediterranean was 40 mtrs lower 10 000 years ago That's why there are dozens of lost cities beneath the sea in Israel and Egypt. We are now between 2 ice ages. I haven't seen the sea rise at all for the last 60 years ?!? Also those papers are from Reuters, the same people who were promoting the not safe and not effective experimental medical procedure with the results that are reflected in the long waiting to see a cardiologist.
I have a question (may require a small grain of NaCl to digest) I have been waiting to see if any concerned climate change activists have computed the carbon foot print of the wars in Ukraine and the Middle East. I know we are all doomed to die by man made carbon dioxide emissions so this seems important to me. I don’t know much about science since I am a retired chemist who only worked a few years in the chemical industry so I am wondering if there any really smart people, perhaps even high school students here or in Europe who can help an old dummy figure this out. I am making a helpful list of things to consider below. Carbon dioxide Sources Fuel used to ship people and supplies to war zones, be sure to include both sides since this is everyone’s Earth. This fuel is used by planes, trucks, tanks non-nuclear ships such as destroyers, escorts, transports or gunboats. You can exclude the nuclear subs and aircraft carriers since the are “Green” electric vehicles, however the planes and missiles they carry would contribute to their carbon foot prints. The good news is that any nuclear detonations will send particulates into the atmosphere thereby blocking out some solar gain, a win for us all! The destroyed buildings, forests and other infrastructure needs to be included as most of the stuff will have been burned. Unfortunately you also need to include the carbon foot print of rebuilding all of that stuff, assuming there are still people to inhabit them. Be sure not to include the nuclear carriers and subs (unless they burn up and sink), then they will need to be replaced. Do not include any electric vehicles such as cars, trucks, electric fighter planes, electric tanks, electric drones of any size. Of course you must include any payload that they fire. And the carbon foot print needed to replace these Green conveyances plus any spent ordinance. People and animals: The people involved in these wars won’t be commuting to work so that is a big savings of carbon dioxide but they will still be generating more or less the same carbon foot print elsewhere so let’s call that a wash. Unfortunately we need to consider the dead animals and people because they will have a final carbon foot print (in some cases literally). As they decompose back to their constituent elements which includes some carbon. Lucky for us however, their carbon foot printing days are over, and as soon as they completely decompose their contribution ceases. They will not be able to be father/mother/them-ers of any offspring so that is another big win for us all. One cautionary note, don’t forget the Baby Boom that will certainly follow the war when the lonely soldiers return home, if history teaches us anything. I am certain I have missed a few things such as Nitrogen and Sulfur oxides that will be emitted by rocket exhaust ,cannon fire bombs and bullets. Also, carbon foot print to the extra food that needs to be grow to replace the destroyed land/crops need to be calculated. I believe the even those who starve will continue to have a carbon foot print until they leave their final carbon foot print (see above). I leave that calculation to those who are wiser than me. Assuming that the carbon dioxide results of this calculation may be somewhat higher than a net zero, it becomes important to figure out who is to blame for the weak (I hesitate to say idiotic) leadership that has allowed the wars to happen, but I don’t want to offend anyone so I will just leave that quest to others.
Brilliant! This subject first came to my attention in 2007 in the BBC series 'Earth - The power of the planet: Episode 2 - Atmosphere'. I have been using that video as an aural comprehension exercise in my English lessons ever since, trying to convince the Engineers I teach, to do something in the domains of activity they eventually work in. I have no idea if that has had any positive impact at all, who could know... What does seem obvious however, is that with more than 8 billion people on the planet now and approximately 220,000 more arriving every day, we should be making a massive effort to reduce births. We have become very blase about big numbers but just think about where you live and a nearby city of approximately 200,000 people. Now most people would like to have the comfortable lifestyle of a citizen living in a rich economy - which is why we are witnessing such massive global migration! SO JUST IMAGINE for that to happen we need to be putting a city the size of Northampton UK, Fremont USA, Kiel Germany or Nancy France on the face of the planet every day!! Not to mention all the industry behind the desires of that population. It puts our predicament into perspective! Every citizen living in a developed economy who has had children will be familiar with the incredible impact of bringing a child into the world. The weight of your dustbin at the end of the week increases substantially, probably you need a change of car, all of the various paraphernalia needed to care for the child etc, etc... Additionally, to this the more and more gloomy outlook for anyone coming into the world today is frankly shocking - climate catastrophe proliferation, more frequent droughts, less food, more political pressure about immigration, cost of living and a whole plethora of problems related to growth in the economy. The Chinese policy of one child per couple had some horrible effects but the idea of reducing population through a demographic program of this type could help to avoid some really nasty consequences in the future.
