Global Dimming Paradox: Are we facing an abrupt temperature spike?
Вставка
- Опубліковано 7 лют 2025
- Global Warming is taking a rare back seat in the news right now, as we deal with the more immediate existential crisis afflicting our civilisation and way of life. But as entire countries are getting shut down around the world, with the rapid reduction of emissions that this causes, is the global dimming paradox about to be tested? Will we see an abrupt spike in temperatures that tips our earth systems into an irreversible cascade of warming feedbacks?
Addendum : Drew Shindell is in fact a professor at Duke University in Durham, North Carolina, NOT Durham North East England. Apologies for this error.

I'm a long term sojournor in the climate 'debates'. I've also had a lay interest in science of any stripe since I was a wee lad. The articulated fair-mindedness in this video is heartening. Well put, and the science was clearly expressed. Being a public speaker for 30 years, I know that this is a real skill, or a rare natural ability. Well done, mate. Excellent transmission of science and dialogue.
I have a small organic farm here in the finger lakes NY and have been chronicling the changing weather patterns, bird migrations, insect populations, and the general shifts that have made it harder to grow the usual crops here and the ability to grow things that are adapted to more southern regions. Over the past 20yrs the changes were gradual but now have become much more pronounced . Most people that don't depend on the natural weather cycles for their livelyhoods are just annoyed by floods and droughts and don't see what the effect is on the environment until they have to pay more for carrots or peas or corn. 20yrs ago I never had to irrigate anything there was regular rainfall now if I don;t collect rainfall when it comes I will lose crops ....so it goes ....the changes are increasing exponentially as time goes on.
It’s called the McPhearson paradox!! Professor Guy Mchpearson first brought it up here is his video. ua-cam.com/video/8j4Lhl8C9rs/v-deo.html
I bet it is beautiful up there. Thank you for commenting.
Very revealing. Thank you. On a personal level as an amateur gardener for may years I noticed two things in Eastern Pennsylvania where I lived most of my life. One is that spring (last date of frost) seems to have consistently moved up two weeks earlier. To witness that in a lifetime is is provoking when you read that ice cores reveal long, long periods of time for incremental changes in global temperature. Second, storms arriving around Halloween (ice and snow) were not only early, but quite severe. Scientists obviously have much better data points, but if you can sense and observe the world is changing, it probably is.
I grew up in Northeastern Ohio and 40 years ago the Great Lakes had consistent ice cover every winter. That winter ice cover has diminished and in some recent years, been conspicuously absent altogether (polar vortex notwithstanding).
As I have ancestry from the Upper Peninsula of Michigan I can also tell you that in my youth (I'm 54 now) the snow pack was measured in yards, now they report it in feet or inches like the rest of the US.
So yes, the climate has changed. And also in that time, there's been a huge reduction in acid rain which was a common occurrence in my youth as well. Many a car paint job was ruined by it in the 70's but not so much anymore.
The reduction in acid rain has a lot to do with EPA mandates for coal fired power plant scrubbers. I grew up near the Cuyahoga River which its having caught fire for the 13th time was the impetus behind the creation of the EPA in the first place. Since it's inception in 1971 the river has not caught fire yet again. And the water in Lake Erie which the river empties into is much cleaner (it's the shallowest of the Great Lakes).
It's also curious to note that my youth coincided with the last grand solar maximum. Solar cycles have been waning ever since careening towards a grand solar minimum. The effect of solar cycles and their strength has a very strong correlation with global and regional climate and weather patterns including temperature and annual precipitation. Another equally important factor to consider is Earth's changing magnetic field. The poles are racing towards new destinations now as the overall field strength has declined by almost 30% since I was born in 1966. And also, the region of space our solar system is now entering has a much more dense energy field to it. As the sun's strength wanes we are experiencing a maximum of cosmic ray flux which itself changes planetary albedo through cloud nucleation. There are fewer and fewer sunny days each year here in the Midwest now than there were just 35 years ago.
While it is indeed nice to be breathing less tailpipe induced smog these COVID days, I wouldn't attribute too much climate influence to humankind. The bulk of that belongs to larger causes like our sun, our solar system, and the space it currently is traveling through within the Milky Way, and of course the drastic decline of Earth's magnetic field (so drastic that global planned updates to the GPS system had to be made in advance of the regularly scheduled ones every 5 years).
The best science I have seen on solar cycles suggests that a grand solar minimum will begin with solar cycle 26. So we've got one more "normal" albeit subdued cycle beginning right now in solar cycle 25. Cycle 26 won't be anything near normal.
people do not understand this, they think everything will be fine.
Having just come back to your videos after a little break I am struck by your incredible talent for presenting soooo many complicated details so clearly. Congrats on your excellent important work! Much appreciated!
Depending upon phony studies to assume that any theories are indicative of anything isn't "talent" if you will forgive me. Papers on heating of the atmosphere due to additional CO2 are entirely wrong. The absorption lines are almost off the emission lines of sunlight making the idea of atmospheric warming due to CO2 a fantasy. Rather most of the emissions of the Sun are absorbed by the earth, converted to IR and moved into the upper atmosphere via conduction. CO2 is a superior conductor in this manner and hence is a coolant rather than an atmospheric warming agent.

I've just discovered your channel and I really find this stuff interesting. Also, you're so pleasant to listen to and so genuine with your well wishes. It is a strange time.
When talking about something so disturbing, it is helpful to hear about it from a pleasant, calm voice. We don't want panic. We want action based on facts and reason.
I lived near a airport back then. It was so quiet for 3 days. Didn't realize how stressful noise pollution is.
This is what Trump misses to convey when he is talking about "windmills" causing cancer.
Thanks for showing many differing papers and conclusions. I hadn't actually seen opposing data to the global dimming concept, and mistakenly thought it was far more certain than it sounds to be. As a scientist, striving to be open to challenges to my views, I really appreciate getting the incorrect understanding of things knocked out of my head. Thank you for looking into this question! Not only is it interesting to talk about the potential of global dimming--or not--but right now is a real live chance to gain far more data about what happens when an economy slows and aerosol productions are significantly reduced. I look forward to seeing the after-action analysis in a few years!

I really love the format of this one and the enormous effort you’ve put in. The content too is level, balanced and evidence based and I really appreciate it.
I really like your style of speaking. It is thoughtful and such relief to hear. It also helps catch my interest. We will argue for a long time about man’s affect on our climate, so it is best for all to just clean it up and see what happens. I think we will be surprised pleasantly.
Just found your site. very impressed. Your ability to unravel the complexity involved in the discussion is flawless. Wish I’d had a teacher as interesting as you when I was at school.
In 2018, sulphur was removed from marine fuels. It would not cause harm to land based people, if sulphur was allowed in Marine Fuel, as an experiment to see if it has an effect on global temperature increase
Yes, good point.
Even if acid rain would come back than it's possible we could not too costly, protect life and buildings . The present droughts and wildfires do probably more damage now.
Having watched these videos I can't help having a sneaking suspicion that we really don't have any way of knowing with certainty what will happen as a consequence of anything we do.
stenka rasin
Totally agree with your statement.
It seems that the vast majority of all the modelling done around global warming to date has not been anywhere near accurate.
The earth is too complex and finally balanced to assume that changing one part of an equation (eg CO2) will not have a cause and effect on another!
Until such time that these models are developed to encompass every aspect to cause and effect, we will never be able to model anything accurately.
Sadly too much emphasis and reliance has been put into taking current modelling as 100% accurate (which is so far from the truth)!
stenka rasin And thus the latest Heartland Institute’s meme of too much complexity to ever know comes a winner.
When everything the american people believe is false, then we know we have done our Job .. We lie, we cheat, we steal.We have entire training courses on it.... quotes from directors of the CIA .

From space you wouldn't notice any difference.
We are nano-scopic & invisible compared to the earth.
Whenever you hear a phoney whiney fake-news brit voice accompanied by "modelling" charts, and ESPECIALLY if you hear reference to ANYTHING from the u.n. IPCC CarbonTaxFraudScam alarmist terrorist fake-news lying propagandists (and their parroting puppets like neurotic threat-a doomberg & fiberal feltcher jihadstin maggot castro tru-grope turdface) seeking to subjugate enslave & dysfunctionalize the world...
when you hear & see this duplicitous delusional pseudoscience then remember these irrefutable FACTS:
co2 is the primary driver of all life on earth,
co2 was 10-100x higher for 99% of the past,
co2 x 10 will eliminate deserts & icecaps,
BOOST the co2,
MELT the ice,
MODERATE our climate,
RESTORE the BIOSPHERE..!!!
duh.
Our planet was a WorldWide Year-Round Jungle for 99% of the history of plants & animals on earth, with 100x the present living biomass on land and at sea, and NO desolate icecaps/winters, and NO barren deserts.
Ice & deserts are the real "climate catastrophe extremes" and they are caused by the CARBON DROUGHT of the geologically recent last few million years.
I have presented the FACTS whereas nothing the parroting puppets say is in any way factual beyond question, it's just alarmist pseudoscience propaganda.
bought & paid shills for the globalist u.n. IPCC new-world-order CarbonTaxFraudScam.
And as for the phoney "sea level rise" LIES....
floating ice DOES NOT raise the level of water it melts into... basic physics, duh.
THE FACTS of the past ARE UNDENIABLE.
Anyone that tries to "model" our future climate as "fact" is a BAREFACED LIAR.
Deforestation & toxic pollution are bad, no question, but...
co2 IS NOT A TOXIN.
and

That's already happening worldwide.
We are likely headed to a great new age of
CARBON PROSPERITY as ice & deserts give way to farms forests & jungles.
Andy MacDonald
Totally agree.
This is climate derangement syndrome.
There has only been ice at the poles for about 5% of the earth’s entire history!
It’s people who need to adapt to the ever changing water level rises and falls and stop pinning everything on CO2 levels!
Thankfully I think more and more people are coming around to the real truth and asking for facts and not believing the climate fanatics who are not showing us facts, only emotive speeches about their children and their futures! Yawn, yawn 🥱
I am waiting to see the effects of the next two 11 year solar cycles and the effect of the solar minimum, which will hopefully prove that radiation from sun spot activity has previously drastically altered our jet streams and this has caused the recent weather patterns.
The world is getting much greener because of a healthy rise in CO2 and that’s all we are seeing.
Michael Mann can go stick his made up hockey stick graph up his ar#e!
The truth will soon be hard to explain as temperatures start to dip off again (like they have globally over the last 5 years)!
Most certainly the current scenario will lead to many studies in many disciplines. Lets pay attention to the real science and not the conspiracies that arise. Be skeptical, follow data, allow for alternate arguments. All of us can learn to use a 'science-mind' , even if we are not scientists.
So lets 'Just Have a Think'
I’m a skeptic but and avid supporter and Patreon of this fellow. Why? because he is a thinker. Btw when I say skeptic I am however a fierce supporter of renewables and limiting human impact
@2:08 he says a 1C temperature variation is common over that particular area. There's just one problem with that; the DTR spike wasn't just over that particular area but the whole country.
@Barry Foster what makes you qualified to stomp on scientists?
I read nothing measured in your comment. simple ideology, just hate, bad morning?
If you are skeptical of the overwhelming scientific consensus, then you are anti-science. There's no other way to put it.
If you think the currently accepted climate model in climatology is wrong, then I have great news for skeptics like you! Science provides you a mechanism to prove that you're right and that the prevailing opinion of science is wrong!
All you have to do is produce a climate model that makes more accurate predictions than the model you're so certain is wrong.
Once you have that, you need to plug actual data into it to prove that your model generates more accurate predictions.
Then publish your findings in a reputable journal, and make sure you include enough information so that your fellow science experts in the relevant field can duplicate your results.
Then present your paper at the appropriate science conference so that you can be cross-examined by an auditorium full of your fellow climatology experts.
Then wait for your fellow climatology experts to duplicate your results/calculations.
Does this sound like too high of a bar for you to pass?
Because the climate model you're so certain is wrong went through all of these steps many times as it was developed and then refined into what we have today.
Don't you find it curious that out of all those millions of science-deniers, some of whom have fancy educations and tons of funding from oil companies are somehow totally unable to do the one thing that would actually prove their claims about climatology?
It must be a conspiracy! There must be a sinister international conspiracy that is preventing all the anti-science quacks from actually proving their ridiculous anti-science claims about climatology! How else do you explain why all those so-called experts keep saying you are wrong! Don't those so-called experts know you **you** are?

Wow, we're loving your classy graphics and virtual studio (to accompany your already calm manner and reasoned arguments).
One thought that came to mind is that the 9/11 contrail case was a poor experiment in that it was limited days and limited location, involving only aeroplanes. The effect may have been statistically insignificant given the noisy spatio-temporal nature of atmospheric and temperature variations. This coronavirus crisis effect on industry shutdowns will be nearer to a global phenomenon affecting all aspects of emissions, and there may me much more to learn regarding net temperature effects of "release" from global dimming by human emissions.
While I agree with what you are saying here, it is the only such experiment we have. At no other time in modern history were so many flights canceled. Today is likely approaching that on a global scale.
Hi Keryn. Thanks for your kind feedback. Much appreciated. I agree with you about the virus - a very important (although completely unwelcome) atmospheric experiment which no doubt all the major monitoring agencies are crawling all over right now. I'll be fascinated to see what results come out at the other end.
Unless you are suggesting that the release of the COVID-19 was deliberate, our current situation is not a “experiment”. It is merely a situation that may supply some useful data.

A follow up video will be appreciated examining the observed temperatures for January through June compared with ten or twenty year global and regional averages. Perhaps also separating out land and ocean temperatures.
The McPherson Paradox goes mainstream. It's about time.
I'm in "Silicon Valley" in California and it's gotten cooler, back to how it was 15 or 20 years ago, and a lot colder at night - there was even a bit of snow in South San Jose a week ago. And during the day when the sun's out it feels like the sun in Hawaii where I grew up - strong.

Your approach is very thoughtful and inviting. Marshall McLuhan adopted a great Ray Bradbury quote and adopted it into his work: "Violence is the quest for individual or group identity". The solution, McLuhan felt, was dialogue. The staging of your show/persona definitely invites that - it's very commendable and I hope this type of thing really catches on. I hadn't checked in on Global Dimming for about 10 years, so it was compelling to see where we are now!
Follow the money we need more CO2 not less. Ask the plants we are all doomed without plants.

You did a great presentation with stunning video editing skills.

Please do a follow up on this subject in a couple months .. to evaluate the effect of so much reduced industrial out put plus the reduction in the airline industry. This could be a real time test of the Global Dimming Paradox.
I didn't see that this was such an old video. I was hoping for some new data.
exactly
There have been massive flooding and extreme weather systems worldwide or is that just me focussing on this subject, China has had it very bad...
@@lynnattwood1716 It is not you focussing on the subject. The predicted weather extremes are
certainly happening all over the world (some areas worse than others). We are entering an
era of potentially very fast and large changes .. as the Arctic ocean becomes mostly melted
and open, permafrost continues to thaw at an unprecedented scale, methane is being released more and more, forest everywhere are burning and releasing huge amounts of carbon .. all adding to it self as a positive reinforcing mechanism. We are living in unprecedented times.
@@jimlamet134 - I'm somewhat new to researching climate change and it's effects. I'm a little confused though on if global dimming will have a real long term negative effect or not? This video here was well done, but seems to not give any solid answers to the question of what would happen if we slowed down manufacturing and flying, driving etc.....and if that would result in less dimming and therefore more heat coming in long term. Guy McPherson says we're screwed no matter what, saying if we stop industrial activity then we'll heat up faster than now, and if we keep going with industrial activity we'll still heat up due to trapped in gases, but maybe a bit more slowly. But it seems mainstream scientists are not concerned about what effect global dimming may or may not have. Color me confused.
This is great thanks, badly needed in the battle to have a rational discourse on the entire subject.
sulfur dioxide SO2 and water H2O gives sulfurous acid H2SO3. This is a weak acid and have a rather low dewpoint. For sulphuric acid H2SO4 and suphates to form, there has to be sulfur trioxide SO3. Theres a conversion of sulfur dioxide to sulfur trioxide but this reaction is relatively slow
You are the best UA-cam Science communicator. Your videos are phenomenal! Thank you
Water vapor is the #1 GHG. According to GHG Theory it does 3/4s of the heating. If you go by prevalence it does about 98%. It gets no attention.
I had wondered about the answer to this for some time. That you have verifiably navigated a route to a most likely answer is excellent.
I feel happy now that a rapid decarbonisation is not likely to be a jump from the frying pan to the fire. I can and will now be far more robust in the face of such speculation. Thank you.
Thanks David. Good to hear the presentation came over OK. Hope you're staying well so far?

I have to admit: after watching one of your videos I usually end up spending a huge amount of time researching the subject. So I can blame you for not getting the things on my list done.
Thanks!
That's amazing! Thanks dryfrog. I really appreciate your support 😀
The problem with this, as loosely admitted, is that the views still rely on models. You can’t, as suggested, aggregate many models to arrive at a solid mid ground consensus. That simply doesn’t work. I do like your presentation style though, comes across very calm and thoughtful.
I believe the idea was somewhat proven as studies suggested a significant rise in global averages post Covid.
Wacha gonna do. Without a model, you have instead a much simpler model.
I've been tracking the population clock (U.S Census Bureau). U.S population is growing 3850 people a day and world wide 218,000 per day. If we don't get that under control (and we wont) it's all for not.
A good, nuanced, informative presentation. I gave it a like, which I don't always do on this channel TBH. But I always keep a supply of cold water on hand for these occasions, and true to form, I'm going to throw some right NOW…
There are a few important elements missing from the presentation. First, it does not distinguish the different types of aerosols and particulates. The clear skies after 9/11 removed mainly aircraft contrails. That is a very localized phenomenon; the continental US is only a small portion of the planet's surface. Of course, there were effects beyond the US, but most of the reduction would be in that area. The contrails are also very limited in time, to hours. But then you veer right into talking about Pinatubo and Mt St Helens, whose emissions stayed in the air much longer, and got to spread far more widely. Therefore, when you talk about global dimming, I have to ask which type you're talking about. If you want to talk about heating up the whole Globe, you need to be talking about things that will persist in the atmosphere and be spread around, and the 9/11 example is not relevant.
Also: If you want to talk about what effect the removal of aerosols and particulates would have, then we should be looking at what specific emissions there have been over the last few decades. Industrial countries have been reducing those kinds of emissions for a long time now-less reliance on coal, more scrubbers on coal power plants, and nearly all cars have cats. China, and somewhat less some other places, have been growing their use of coal, using more cars, and so on, offsetting those trends. I'd love to see some stats on those kinds of emissions from various places, over time. I don't know when I've ever seen those. I'd definitely give you major kudos if you come up with that. And to have any clear conclusions, that's what we need.
I'm definitely a global DIMMING skeptic at this point. Of course, I'm willing to consider new information if it arrives, but for now I'm thinking of three reasons to blow it off: (1) the geographical non-uniformity of these emissions, (2) the fact that different types of particulates and aerosols have different warming properties (some reflecting light back to space, some absorbing it, and all with different lifetimes and altitudes, just for starters), and (3) the fact that these pollutants, while they may block some sunlight, can also block escape of IR, especially at night, so they may not be holding down temperatures as much as you might guess.
So there. I just had a real think. I hope you're pleased. But I'm sure tired now.
@Brin Jenkins The reality of heat releasing from chemical energy conversion ( for example pC6H12O6 + O2 > CO2 + H2O + Energy) exists next to the reality of atmospheric CO2 and H2O absorbing infrared radiation at different wavelengths.
@Brin Jenkins One thing can be two things at the same time, a forcing agent and a positive feedback.
@Brin Jenkins It might appear illogical to you, but the physical facts are that CO2 becomes less soluble in water as water warms and, when in the atmosphere, CO2 also absorbs infrared radiation at wavelengths which atmospheric water vapor does not. Therefore atmospheric CO2 can be both a cause and an effect of an increased amount of energy in the earth system.
@Brin Jenkins Life also appears to contradict logic, but it exists nonetheless.
@Brin Jenkins What would destroy what? The planetary climate system finds a new balance eventually.
Has anyone ever looked at Electromagnetic Radiation, Satellite and the Microwave Communications Systems Total Output around the World.?
Also I believe an area that should be looked at is the Magnetosphere for fluctuations in its strength since the Pole has accelerated its movement towards Siberia. It could also explain the recent record high temperatures in Antarctica.!
This may play a factor along with the aforementioned in my question.
It will be interesting to see what effect the sharp reductions in pollution has on April global temperature. We are in a global brightening experiment.
I know of someone in China bordering hubei province that said its been unusually warm in their area since February and clear air meant they have been able to see the stars in their city like never before.
Tim A. Fits the expectations of reduced aerosol masking aka global dimming.

Thank you for talking about this. Very few people seem to know about it.
So the good news is that declining aerosol saturation won't wreak too much havoc...the bad news is that no attempt whatsoever is being made to implement mitigation strategies to keep temp rise below even 2 degrees, and the current crisis is likely to lead to a further sidelining of environmental priorities as economies ramp up their production lines to stave off depression. Feels like we're born to lose on this one.
I find myself believing much of what both sides of the climate change debate say. However, it seems to me that the gradual removal of fossil fuels from the energy cycle is by far the safer option.
The big downside is it may make foliage and crops less lush. Always a downside to deal with.
You should see what they do in the Netherlands. How they capture their own co2 output and pump it directly into what are basically food bioreactors. The Dutch as so brilliant these days! Probably one of the most advanced civilisations atmo.
Gradual, or rapid, because rapid is still going to take a few decades. Also we should not be trying for zero carbon, but a reasonable goal like 20% of 2000 levels.

The northern hemisphere has had three of the top ten snowiest years the last 3 years. Northern Africa, the middle East, The Arctic have been very cold this winter. 1930's were by far the warmest decade.
Correct.
Your claim about the 1930s being the warmest decade is nonsense. You will not be able to support that claim with any evidence.
As for the Arctic, February sea ice extent is slightly higher this winter than the previous two winters, but the long term trend is down, as it is for all months and seasons. Here is the February extent data since 1979:

You will note than since 1980 there have been 8 occasions when sea ice extent has increased for at least a couple of years, as has happened up to this year. Such fluctuations have no significance as far as the long term trend is concerned.

Just discovered your channel on YT. I was looking for info on global dimming and came across this. Your calm manner and the clearly robust, objective way in which you've presented the content has genuinely made me feel much calmer about the recent news regarding the Greenland Ice Sheet, which is something I found very upsetting in recent days. I've actually found myself having some very dark thoughts about the future of the environment & humans within that. But this has really helped me to understand this particular phenomenon (dimming) better. So really - just a HUGE thank you for that.
And if you're thinking of other ideas - I would like to know more about the Greenland Ice Sheet news as well, to understand the impact that will have. Thanks :-)

Just curious, why did it take this long?
Thank you. I appreciate that.
Al Gore and David Suzuki( a geneticist) have made a lot of money on this issue. Al Gore has four children, all of them were educated at Harvard. That has never happened to any other family, no matter how wealthy they were.
No other family has been fathered by Al Gore? I find that hard to not believe.
Very nicely done. Best discussion of something I've been looking at for over a year.
The temperature sky rocketed in England during covid when there were fewer cars and planes.
It seems like that statement by Dr. Smith was only saying that a transition away from fossil fuels, thus removing aerosols from the atmosphere, wouldn't cause a spike because it would be too slow. That doesn't address the question of what would happen in a situation like now, with a lot of them actually be removed almost instantaneously.
But I guess we can just wait and see...
Hopefully there will some analysis released on the results of the chinese shut down before too long which will contribute to understanding this.
grindupBaker You’re mistaken, I don’t think the climate scientists are guessing. I have as much trust in their capabilities as I have in those of scientists in any other field, since I don’t see why I shouldn’t. My comment was genuine.
I am glad I stumbled across this channel a few days ago and the temperature spike from 9/11had been on my mind. Thanks for the video! Needed to scratch that curious itch.
Great story ! Thank you and my opinion is the transition to clean renewable energy and having an increasing amount of respect for nature and our natural world is so important for humanity in a positive sense :)
I believe that instead of fighting amongst ourselves we should be together fighting against the dark cold vacuum of space ! We live on this beautiful planet that seems smaller and smaller and more vulnerable every day and we have entire economies built on killing our fellow human . It’s not so good tho many things may have been learned I think we can stop now ! Let us together expand into the solar system and the universe !

I went back to review this article today, in 2024. It’s becoming clear that your assessment is accurate.
Dave, superb graphics on a very deep subject. I'm sure there is enough material for two or more videos on this subject. Keep going!
Excellent Presentation...AGAIN.
Cheers to the Facts you bring UNSPUN.
A couple of things I noticed in the presentation. Modeling has seemed to consistently underestimate changes and effects. There are regular stories of how the real effects of climate change are more often larger and faster than our models predict. The chart depicting the sensitivities of different areas to aerosol removal does highlight that the poles are more sensitive to it. So one might expect an increase in the speed and quantity of melting in those areas, which will have its impact on water levels and the nature of our oceans. Those changes may also accelerate change in other dimensions of our climate.
John Benson Exactly
Fantastic presentation style! 👏
Thank you for presenting this. Admittedly it does not clear anything up, but even the fact that you've reminded people that aerosol masking effect is important is vital to general understanding, and to reduction of surprise in case it does in fact cause a near future spike from something like the present Covid-19 shutdowns. Thank you for your work, man. We watch you almost every week.
Why do you say it doesn't clear anything up? Watch it again, particularly 12:00
... understanding Milankovitch cycles, Solar cycles and Ice ages is important
I’ve been waiting for this video. Thank you!
I'll place the above links on my blog for future reference. The narrative was a bit too fast for me at this hour, 3:30 a.m. Normally I follow the narratives closely. We need many analogies, even though we can intuit the effects of removing aerosols. Where I live in Orange County, California, most people seem to remain stuck by the terms "weather" and "climate." They cannot make the leap from today's cold to global warming. Thanks for your hard work and content.
On the other hand living in the East of Austria (already the Pannonian lowlands) we are facing an exceptional cold time just now after January through to early March have been much too warm.
Since last week and presumably the next week we are having up to -4°C during the nights, with one ore two nights in between having +2-4°C. Up and down.
But during the daytime - yes mostly blue sky and cold winds, despite common early spring temperatures.
That's very unusual for that time of the year. Early blossoms at the trees (we are are vineyard and fruit farming area) will not like that.
8:07 min "We believe ..." that does not sound like a scientist, it sounds like a religious ideology.
Scientists should never ever let us know, what they believe, they should always talk like scientists.
That is the reason why people doubt science. Wrong use of language.
My rules so far for scientists language means to avoid these few words in every statmenet :
- truth
- believe
- belief
It really is not hard to just use your brain a bit outside your discipline.
The fact that scientists make it clear when they are talking about things they have reason to believe and things they have proven is what makes it different to ideology.
@@owenbevt3 So using ideologically biased vocabulary seems fine for you, even if there are alternatives that sound a lot more neutral and distanced from any form of ideology ? Why u want science to sound like a religion ?
Why you want to trigger religious feelings in people, that listen or read this kind of sentences from scientists ? Does it any good for science ?
What these studies to not take into account, is the lowering of surface albedo, when industrial dust from China falls on the northern ice sheets. It is likely this effect that has warmed and melted the Arctic.
See the paper: Modulation of Ice Ages by Dust and Albedo.

Everything goes in cycles on earth. One day it will start freezing again.
Good video Dave. I was hoping there was going to be some solid final answer at the end, but it sounds like it's all still up in the air :-) Anyway, you did show studies that said their would be regional impacts. I expect there will be more studies in the future based on current industrial reductions.
12:00 sounded pretty solid to me. The Arctic effects are a concern, though.
Hi David.I think the regional variation is something the world will need to be very mindful of, but the overall average global atmospheric increase as a result of rapid aerosol reduction (that's to say, over a period of 10 years) looks to be projected as somewhere between the 0.2C in IPCC AR5, through the 0.3C in the Shendell paper and then anything between 0.5 and as much as 1.1C in the AGU paper. Hope you and yours are keeping OK so far? I haven't seen much about Thailand - what are your infection rates like?
One thing for sure, where I live it's pretty evident that cloud coverage has a big impact on minimum night temperature. By analogy contrails must have an effect, but the impact may be much lower that a 100% cloud covered night versus a dry clear night.
Brin Jenkins those are probably chemtrails. Contrails disappear almost completely. If they leave an x shaped grid or parallel lines that thins out into clouds that dims the sun, that’s chemtrails. Look up geoengineering. Pisses me off.
Finally somebody is talking about reality.

@@claudermiller i dont think so dude. Check this guys work and concerns. They are far more grounded then what you see on the news. This guy talks about real stuff that is real really.
Excellent discussion. I am aware of nearly every paper and observations you refer to. Global dimming has,, it would seem, has balanced somewhat the temperature rise. Removal of those aerosols may be quite problematic. The longest running global climate experiment I am aware of is the British Admiralty has for 2 plus centuries maintained evaporative daily observations anywhere they have been stationed around the globe. The Evaporative observations are the very essence of simplicity, a broad tub of water, and a recording of each day, how much water must be added back into the tub to bring it back to the zero line. Evaporation is greatest in a clear sky and strong sun. The photons do literally bounce the water molecules out as a free vapour. The evaporation rate in the past 100 years has reduced tremendously,,, Global dimming. An Israeli scientist/engineer has quantified similar solar reduction effects. Satellite photos of California contrails pre- 9-11 and post 9-11 give graphic testimony to why sunlight is being reflected. Pinotubo (sp?) and Mt. St. Helen are poor sisters to the eruptions of Tambora (sp?) and Krakatoa, each of which have been credited with Northern Hemisphere years without summer. 1783 and 1816.
Noted effects to the reduction of sulfur in Jet A,, may well have been responsible for the droughts of sub-Saharan Africa. And,,, perhaps a temp solution to keep temp rise to a minimum is to add sulfur to Jet A.
I personally think,, I do,, that global dimming has been hiding the worst effects of global climate temperature rise.
Hey, I think too that aerosols have been underestimated somehow. Perhaps you thought too the following??
We have all that catastrophic weather everywhere over the globe.
It could be normal "natural variability" if it was only on a few places. But this is like hell breaking loose everywhere. It's the jetstream, they say, but why is that jetstream suddenly going nuts??
So I think with Covid, the industry kept running but people worked from home and there was in general a lot less transport on the roads, the sea, the air...
Till now that effect could have been underestimated and we feel now the full power of CO2 because of the clearer skies. A lot more water evaporates from the oceans.
This is now even more speculative, I admit but the water comes down very localised as if the cloud formation is also disturbed. Yes, again that jetstream blockage but perhaps also different condensation nuclei conditions where the drops stay in the air much longer.(???
Thank you for bringing up the subject of global dimming the paradox make no difference as to what we should do at least from an ethical perspective . We still have the obligation to reduce pollutants and carbon no matter what the outcome , the damned if we do damned if we don't scenario shouldn't stop us from taking the green path .
Thanks so much for this well-researched, well-presented, balanced and informative video. Excellent work, as usual! Your subtle sense of humour is also very much appreciated.
95% of the greenhouse gases is H2O; which seems to be missing on the IPCC chart.
William Munro so what? How long that gas can stay in the atmosphere compared to CO2 and what’s the relation between them? This is your home work. IPCC also skipped that Earth is round... why would you state the obvious?
Excellent video again, Dave. Only a few weeks ago I cited the historical 9/11 [post 11th of September 2001] clear skies and expressed a wish that the momitored air quality over the globe be eventually modelled and studied in detail, because here is a test case beyond all test cases.
Also, I think you trod the "heated exchanges advice" path extremely well at the end. That must have taken a fair while to write. 😎
As usual, liked and shared.
Hi Andy. Thanks as always for your feedback. I reckon this current virus crisis will be a massive (unwelcome) opportunity to test some of the contrasting theories.
To your second point, comments so far seem to be quite civilised this evening so perhaps my suggestion has had a little bit of an effect :-) I hope you and yours are keeping well so far? All the best. Dave
The ice, the canary, in the Arctic speaks volumes and is plunging since about march 20!
@NEAR TERM EXTINCTION - HUMAN Alarming??? I'll say, think 100% - not long now
Thanks so much for your thorough research.
Gentle suggestion well done.
Now for a second listen.
The officials still haven’t announced more on this, yet. I’ve seen nasty temperature jumps in plenty of places this year since the decline in aerosols. Good work.
And not in others - here in Central Kansas, we only had 5 100F days this summer - quite a few in the 90s, but this was not a super hot summer for sure. We haven't hit first freeze yet, but it looks like it'll be about on time (mid October).
Observationally, from the 1970s til now here, we have had slightly milder spikes in temperature (I recall several days when I was a teenager in the late 70s/early 80s where we had 110F air temp, and also had -15F winter temps) we haven't had either of those in several years.
The thing that keeps getting lost in all the carbon discussion is this: we are significantly more "green" and "forested" here in Kansas than we used to be - when Kansas was settled, there were only a few trees along rivers, that was all... now there are trees everywhere (thanks to initial planting in the 1930s/40s to alleviate the dust bowl) and those have now moved through a 2nd and now 3rd generational growth... and with no 50,000,000 head wild bison herds running to trample or eat the trees down, nothing has kept them from propagating. So now Kansas has woodlands that it never had... funny thing is, I hear about the "cow farts" but no one seems to remember the vast herds that used to be here.
I think the honest answer is, the scientists still don't have much clue about what's driving everything, and there are some bad actors with an agenda they want to press into a mold of "science" - without considering that too many of us casual and not-so-causual observers are paying attention to them - your aerosol example is a perfect one. The amazing thing to me is how well Canada has controlled the climate this year - all the forest/range fires in the Pacific Northwest seem to stop at the Canadian border... it's almost like there is something else making those fires happen...
Thanks for your efforts and clear explanation
"We have no idea, but we are going to go with the theory that gets us the most funding."

Scientists don’t go into their field to get rich as a general rule. But the scientists who do want to make serious money pick up a MBA to go with their PhD and sometimes make millions running a company. I know several scientists (and many engineers) who have done that. If you are smart enough you become a billionaire (Jacobs and Viterbi come to mind). Climate scientists instead stay in their jobs trying to save humanity from dying while idiots hurl insults as them and the world moves towards a Dark Age lead by fascists. No one model of climate change seems perfectly correct, but they are improving. As for climate change happening, 121 F in the Los Angeles are over the weekend, 2 million acres of fires burning in California, 2 hurricanes in the Gulf of Mexico at the same time, 10 years of record world temperatures, etc. It seems like like things are different to me. Or have the deniers admitted it is getting warmer?
Thanks JHAT for another spot on take. Excellent video on the most complex topic in the climate debate.
@grindupBaker Jasper Kirkby at Cern is working on this. Checkout the CLOUD project. Keep in mind that clouds are also randomly effected by naturally occuring dust and no pollution is needed to seed the clouds. "There is no need to fear clean air" as Bjorn Steven at the Max Plank Institute who is also studying this situation. Plant a tree.
Another excellent video and presentation. I really hope your channel keeps on growing, so that you can reach more and more people, and lead them to "Just Have A Think".
This is dichotomy that definitely needs to be addressed, but we also need to plow forward with efforts to reduce the burning of fossil fuels and of CO2 and NOX emissions. This may have to be done more slowly than many people think, but it needs to be done at a faster pace than it is being done now.
Nuclear energy is probably the fastest way to address this, especially if we manage to work with Thorium, which reduces the risks associated with nuclear energy dramatically.
Please keep up your fantastic contributions.
Nuclear power of any sort can't compete with the falling costs of wind and solar power. It's all about money with utilities and they're choosing the low cost energy, and that's wind and and solar.
Very interesting video. Thanks for the great topic. Regarding the nature journal publication, one of the authors is from the Duke university located in Durham, North Carolina, US, which was mentioned as Durham County in England. Since Durham county in England is home to another famous university, namely Durham University, I thought it may be confusing to some audience.
If climate research is funded by governments, who are only interested in results which show human induced climate change, can we really expect the research to provide unbiased results? These people don't want to upset the money cow.
Most of the time they aren't though
Maybe you should consider not calling hypotheses theories. Theories are models that have been tested and proved to be accurate. Hypotheses are potential models that are so far untested sufficiently to qualify as theories.
If I understand correctly this study points out transition to clean energy won't have that big impact as proponents of "McPherson paradox" see. What can happen if the whole emissions would be shot down due to a pandemic (for example)? For this answer we need to wait but something is telling me data is collected and paper is written.
I think the same Mariusz
@Primal Magic Clean energy does exist and you know what I mean. I won't argue about your private definition. Keep your own but this doesn't change reality we share. Energy density of gasoline is nowhere near of nuclear fission, so again you are absolutely wrong. Energy efficiency was address by Just Hava A Think before but nothing will change the simple fact that solar panels, windmills and small scale water turbines can be solution for climate change, can coexist with ecosystem we need to survive and don't affect air quality or climate on other side of the globe. Fossil fuel energy does.
@Primal Magic Where did I say anything about cars with nuclear reactors? I did not say nuclear power cannot be seen as a clean one but I'm pretty sure you'd agree "it can affect air quality on other side of the globe". And now any comment to what I WROTE BEFORE?
@Primal Magic: Right. We need to shrink our per capita consumption and the size of our population and especially the fossil fuel consumption per capita. The economy is too large.
I hope to see an update on this topic discussing the local dimming paradox due to the forest wildfires emitting soot, for examples, in various localities (Autstralia, West Coast of USA, Arctic, etc). Have we gotten local temperature data during the fire seasons?
1:35: it's light that is reflected, not heat. I'm suspicious of the amount of energy that is actually reflected back from ice and clouds in standard ice age theory. I suspect in reality it is smaller than the amount envisioned by science reporters.
Yes, climate is changing but not necessarily due to man-made CO2 emissions. A modified theory of gravity allows periodic extra tidal energy to transport heat from the equator to the poles. This brings increased precipitation which falls as snow. This accumulates into advancing glaciers. Glaciers are always melting but if the extra snowfall decreases then the glaciers retreat and the world enters an interglacial.
The snowfall of Antarctica has increased by 10% in the last 200 years which indicates the planet is slowly entering the 100,000-year cycle.
CO2 is a default mechanism from out-dated ice age theory. This is what Arrhenius based his research on and Greta bases her alarmism on.
Heat is light, that is they are both electromagnetic radiation.
@@myothersoul1953 Similar force-carriers, yes, but *not* the same thing. I can put my hand on a white oven and it can feel cold. I can put my hand on a black oven and it can feel hot. Light is reflected, heat is radiated.
I remember when in the early 90s they said the uk would have a Mediterranean climate by 2020. It was then called global warming.
I notice they've changed the name to climate change now to minimize the incongruity.
I also remember as a student at Manchester university in the 70s being told we were heading for a mini ice age !

I too was told about the future cooling period that was looming when very young. I carefully calculated it out and much to my horror and surprise it would occur in my lifetime.
At that time the wobble of the Earth's axis, Volcanic eruptions, solar dimming, pollution, wildfire smoke, methane release etc., etc. and on and on were not included or discussed. At my current ripe old age I have concluded we don't have a clue and we should stop scarring children unnecessarily.
