Why do TH-camrs replace videos so rarely, even if they know a video contains a mistake?
It's because if you upload a correction, that will be recommended to people who have already watched the first version. They are unlikely to watch it again, or not watch it entirely. The almighty algorithm concludes that the video is not interesting and stops recommending it to other people.
In brief, taking a video down is a bad idea.
As you see, I did it anyway. That's because the first version of the video contained a serious mistake, which is that I said that temperatures would continue to increase after reaching net zero. I had forgotten that carbon dioxide is taken up slowly from the atmosphere by natural processes, so left to its own devices the levels will actually slightly decrease. This together with the lag of temperature behind the carbon dioxide level is expected to stabilize temperatures. (Provided no other sources contribute, like methane leaks from the ground etc.)
It's a mistake that you find in other places as well, but I think it's really important to get this right and I do not want to contribute to spreading it.
You will greatly help us if you let this video run until the end, maybe give it a thumb up if you think it deserves it, and share on your socials, if you still use those and if you think other people might find it useful.

Thanks for your patience. We try really hard to avoid mistakes, but sometimes they slip through despite our best efforts.
Thank you for bringing so much real and correct ideas/information in your vides and in your writing
Alright.. I'll watch an episode of friends while your video is playing on my phone.
Tread carefully might lose a lot of subscribers over this one a lot of idiots out there think it's completely impossible to get rid of positive carbon emissions.
Admirable. Your capitalism video could use some similar thoroughness though.
We can easily use excess solar energy to initiate Paralysis on organic material and carbonize it then take that carbon and put it into the ground which will help things grow because it is like a coral reef for nutrients in the ground... and this process will off gas usable fuels that can be burned for heat or other sources.... because it's done in the oxygen free environment you maintain the carbon structures and because you're putting the carbon back into the ground it becomes clean energy that helps you grow more food that you can use the waste from to make more clean energy.
I'm so old, I can remember when "Net Zero" was a company that promised free internet. Yeah, that didn't work out either.
I'm so old I can remember when climate scientists were telling us we entering a new ice age. They have no more idea now then they did back then. But it worked magnificently as a funding program !!
@@tuberroot1112delete your existence
@@tuberroot1112 That was due to all the smoke. We mostly fixed that, so that's why it didn't happen.
@@katrinabryceaccepting that happened in the US, yet it wildly increased in China and India. You might want to rethink your conclusion.
@@tuberroot1112 That was H. H. Lamb and what he said in the introduction to one of his great books was that if it weren't for greenhouse gas emissions from humans we'd be going into an ice age. If you look at Net Zero from that perspective, it's a terrible goal besides being impossible. Cold will kill more people than +2 degrees C will.
An awful lot of manufacturing moved from the us and Europe to China at the same time the emissions dropped in the former and raised in the latter. I don't think this was so much a reduction in emissions as much as just moving them around.
There were also real emissions reductions in the US and EU, due mostly to switching from coal to gas and renewables for electricity generation. China is also cleaning up its grid and transport sectors at a rapid rate.
No it did not just move them, it increased them. In the west we use gas, in China they use soft coal. Assuming the current Chinese regime lasts, which is questionable, the "Greening" of the EU and US has and will continue to raise because it changed and will continue to change the emissions from gas to coal which employs more people than employed in the EU and US who will live in newer more energy demanding housing powered by burning coal in addition to operating the factories.
This is not particularly clear because the Chinese either lie or simply fail to report their statistics.
@@incognitotorpedo42 Renewables, yes. Gas, no. Gas is as bad as coal for climate, replacing CO2 with methane. 70 countries have mostly renewable electrical grids, 23 at or near 100%, 2 near 100% total energy. Almost all energy being built in the world now is renewable, while efficiency has replaced more carbon than anything. Primary energy in general (direct use of fuels in transportation, industry, & buildings) is being electrified all over; that's the necessary first step in renewablizing it.
"Gas is as bad as coal for climate"
Look up the carbon:hydrogen ratio in methane vs coal and think about that again.
Carbon has negligible effect on climate as an honest use of the radiation codes shows. With coal it's all the other stuff especially from soft coal. FACT is that US emissions have gone done due to switch from Coal to gas.
Sabine is the ultimate no-bullshit scientist. I'm doing research on this topic and it's important to recognize that a lot of our environmental initiatives are a lot of noise - and short on substance.
Well, it's the noise that gets you the funds.
When we consider how much carbon capture and storage AND carbon removal costs, we should consider if there are other more effective carbon-lowering investments that we could do instead. If the former only reduces CO2 by a fraction of a percent and for the same amount of money we could transition away from fossil fuels by investing in additional renewable energy, reducing emissions by several percent, then the latter investment is the wiser.
I was midway through watching your original video, when it conked out. Thank you so much for your integrity to retract this video and repost. These are complicated topics, and we appreciate your acumen in researching and conveying these to us, whether or not they concern Einstein or quantum mechanics.
I can't help but notice how we in the West claim good economies while greening. 😂 While being wildly dependent on the developing world for almost all goods. So we are actually responsible for the carbon of the developing world. That gives us the ability to have a service economy while downplaying our impact on co2. It truly comes across as disingenuous.
To further add injury hammer third world countries with "your emission bad" (even if they dont have the highest emissions) that way they get mixed signals on wether they are allowed to industrialize or not lol.
So we are actually responsible for the carbon of the developing world.
They are responsible for their own actions.
@bastiaan7777777 actually when you think about it. The companies are Western with a clear goal of suppling that market. Consumption in emerging markets is the growth potential. The clear goal is to take advantage of cheap labor and supply the West. Of course, they'll use this opportunity to grow. It's not helpful, however, to pretend it's not our mess. It is!!!
@@jeremyholbrook2094 You are pretty ignorant if you think that those countries produce exclusively for the west. Also, why deny those countries their wealth coming from said productions?
@bastiaan7777777 The base of profitability lies in the West. The growth prospects are emerging.
Hi, I'm a tree!
Some fun fact: there's an expression in Japanese which sounds like "ki ni naru" and is written 気になる. It means:
1. to weigh on one's mind; to bother one; to worry about; to be concerned about; to care about; to feel uneasy; to be anxious
2. to be interested (in); to be curious (about); to wonder (about); to catch one's eye
3. to feel like (doing); to feel inclined to; to bring oneself to (do)
But if you write it like 木になる, it has the same pronunciation, but it means "to become a tree" (or "I become a tree" as Japanese verbs don't have inflections for person).
Combining these, you can say "ki ni natta" and it will mean "I got interested in" or "I became a tree" depending on the context (in speech) or depending on how you write it.
CONGRATULATIONS! You won a "Context' box from the purveyors of pure truth.
The countries that have reduced their GHG emissions have done so by closing their carbon intensive industrial base and farming the work out to developing nations. So really they have not prospered from reducing these emissions. They have just moved them to another continent. Excellent content as always.
Most European countries closed their coal mines and heavy industries over 40 years ago already though, much of the recent carbon reduction is from replacing coal with gas & renewables.
France survives because of the evil Nuclear Energy....and Western Civilization is ok with China dumping pollution because it manufactures its goodies such as smartphones, and cappuccino machines and clears the conscience by giving billions to Third World Dictators while they rape the natural resources....it is phase two of The three composing factors of the "White Man's Burden" are Christianity, Pragmatism, and Manifest Destiny; they are explained in detail and an attempt has been made to show how they form a cohesive unit, and in turn, a foreign policy.
@@rey_nemaattoriand, as OP says, offshoring & selling off carbon emission rights.
They have not reduced their emissions either, they have just sent them to another country.
not true, draconian regulations on automobiles and nuclear power in France counts for a great chunk of the reduction.
What is this net zero everyone keeps on talking about and is it better than coke zero?
or sugar free steroids?
It is a tax accounting trick - get your carbon credits for manufacturing in China but that’ll never get the atmosphere carbon dumping down. It is a fraud.

@@ThatOpalGuy literally nothing is better than that.
Taking down a video because of a prior mistake, and correcting that mistake in a followup video despite being punished by the algorithm deserves respect.
Burning trees and capturing the carbon from it is an idea I haven't heard talked about before, but you are right in that it's the released carbon, not the combustion that's the problem, and that burning fossil fuels is releasing excess carbon while burning trees would be burning non-excess carbon. Although I am sure things are more complicated that the simplistic explanation I have here.
Just for awareness there is research with a diffrent solution to the climate change with experimentally verified results the gist of it can be found here th-cam.com/video/tdhfuu5lPNM/w-d-xo.html or search climate error on youtube
carbon is not a problem, it only has benefits - more harvests, more trees and plants, deserts receding and green cools the planet again...
@@MarcoVermeij excess carbon is actually harmful to plants. There has been studies done where the CO2 content in the air is increased (inside a controlled environment) and plants actually grew less. I also believe there were models created based on the data.
Now I don't remember the specific reference off the top of my, but I am sure if you do some googling you'll find it has long as you don't stick with your bias.
Also, Venus proves excess CO2 can be very bad. CO2 in Venus' atmosphere is believed to contribute heavily to why Venus is a lot hotter than it should be.
The resistance to CCS almost reminds me of the Gatorade scene from idiocracy.
"Fossil fuels and combustion is bad!"
"Yes, because they release carbon into the atmosphere."
"So what should we do about it."
"We should capture the carbon so it's not released into the atmosphere."
"No, that's a bad idea."
"What? Why?"
"Cause that would not reduce the use of fossil fuels."
"But why would that be a problem if we capture the carbon?"
"Because fossil fuels are bad!"
"Yes, because they..."
Sigh.
Carbon is not bad, carbon is life. Period.

With all due respect, but how about supporting the politicians that are trying to achieve this rather than a sympathetic, intelligent bystander who can just move on with her life after making this video? I come from the Netherlands, the country of Timmermans, the architect of the Green Deal. He is getting a lot of nasty reactions.
That's because the decisions of politicians affect everyone while opponents of climate change will never watch this video resulting in a like minded echo chamber. Just as there are like minded echo chambers advocating the total opposite in other TH-cam channels.
We are all shielded from that, contrary to the politicians that have to take the bullets (sometimes literally, see the recent Ecuadorian elections).
Hey Sabine, I want to pinpoint out that another mistake that environmentalist groups make is opposing nuclear power. It's the cleanest and safest energy source that we could have, but is phrased as 'dangerous' by infamous accidents. Talking about that, there were 3 major accidentes in history between the more 100 nuclear power plants around the world.
Many enviromental groups and the IPCC support nuclear power.
Most people do not want them standing in their backyard.
There are plenty of reasons to not like nuclear but at this point I don't object in principle. The problem is that they are very expensive , take very long to install and they tend to lose vast amounts of money.
@@lrvogt1257 Not in China or in 80s France. It is a matter of will
@@seba24000 : French nukes are going bankrupt. China is a command economy. They don't have to worry about profit margins.

Space Scientists are just a Klan of Speculative Globeheads.
I love your videos Sabine. You hit the nail on the head with confusion over carbon removal and carbon capture being confused by many people, in fact there are so many problems with nomenclature in the whole climate change field, I guess because it is a "new" field of interest. From the components of a domestic PV system (inverter now means something so different and more complex to what it did 10 years ago), to the many terms and acronyms used on a bigger scale.
I think another area of poor understanding is the magnitude of effectiveness of different things we can do ourselves. I think many people believe installing PV is the best low carbon decision for their domestic heating, which turns out to be very wrong. I had a house largely heated by fossil fuels (methane) and I switched to a heat pump and a renewables tariff. After six months I did a fairly detailed calculation of the CO2 emissions from both setups and was quite astonished that they had fallen by 97%. I had done it as fairly as possible taking into account the renewable energy mix of my supplier and their lifetime carbon intensities. This reduction translates to a 10 tonne/y reduction in CO2 emissions, for context this would be equivalent to 10 transatlantic flights per year (not that I fly anymore!). Or about 6 times the emissions from a typical (ICE) car driven a typical number of miles per year.
In the above calculation I also had changed and inefficient gas cooker for an electric one. I calculated that a more typical house would save 95% of its CO2 emissions, still a colossal change.
By reducing the number of human births by 99.95%, we can reduce the total carbon in the human biomass by 99.95% (same as it was -10KY). The 0.05% human biomass would then also be producing less CO2 accordingly.
Feeding Africa, Gaza, Yemen was a bit of an own goal!
I'm glad you focused on eco-system restoration at the end. I've long thought that if we took a look at building up new ecosystems, and revitalizing old ones, much of the carbon capture would start to take care of itself. I also think new strategies like regenerative agriculture need to be looked at more seriously. If we start treating our farms like ecosystems we'd likely environments flourish.
I understand why institutions focus on carbon dioxide, as it is easily quantifiable. However, I fear an overfocus on just the molecules, rather than the cycles and ecosystems in which those molecules are involved, misses the forest for the trees. Here's to focusing on building reslience through ecosystems!
Yes, let’s not forget that climate change is just one part of the problem. We can live in a perfectly net-zero world while still destroying the Amazon and ravaging seabeds.
Your not wrong... But also, we have in just a century liberated millennia worth of sunk carbon.
Nature will not simply catch up without our application of technology, which is what has brought us to this point.
But don't despair the numbers work out, we can undo what we have done.
Life isn't the only way to build co2 into HC chains for permanent storage...
That is actually how climate cooling project Justdiggit works. It has proven it can contain desert land, preventing them from growing, and even reclaim desert areas by making sure rain stays at the same place instead of flushing away. The net result is that new vegetation grows at areas where there was previously none.
The amounts of CO2 we are emitting per year far exceeds the amount that biology can absorb. That is the problem.
@@alanjenkins1508But it starts to help when net-zero is reached.
I appreciate your call for carbon capture, I am only worried about the insane amount of energy that will cost and whether that energy couldn't better be used for other purposes.
Carbon capture is a complete fantasy, or even a scam.
cripto-mining seems to be a a better way to use it.
I'm not able to prove it, but i suspect, it would be in most cases much cheaper to stop CO2 Emission than to capture it later... but you can sell Carbon capture as a hope, and a reason, not to stop emitions right no... we can just go on... sad, but this is the way, most humans are.
@crypto anything sucks huge amounts of power and releases heat.
Of course, if scientists and engineers are interested in doing this then they will develop a way to carry this process out efficiently. Or else it would've been impractical to make it work at a large scale.
Bioenergy also captures carbon via root deposition. The plant grows above and below ground, but we only harvest the above ground portion. No till agriculture plus deep rooted perennial plants cause carbon soil levels to rise. Forests and pastures are both good at this. Coppiced biomass has the ingredients to do so, but I'm not aware of studies on this.
I have read that even if all emissions were stopped today that temperatures would continue to increase until equilibrium was reached.
Yes the ocean takes 2,000 years. Well-known simple science.
@@grindupBaker More like 100 years actually, a regular sized lake take 10 years.That means in 2124 all excess heat from our modern solar maximum will have vanished.
Yes and emissions keep rising too.
@@lrvogt1257 They can keep rising how much they want to would still not make sweden the center of the world a tropical paradise anyways.
@@albin4323: That's both true and irrelevant. The equatorial areas will experience an increasing number of extreme and inhospitably hot days and increasing food insecurity leading to social unrest and migrations.
Because of the more extreme waviness of the jet stream, further towards the Arctic could be anything from drought and fires to floods, early or late frosts and invasive species. SEE: "NASA Watching the Land Temperature Bell Curve Heat Up (1950-2020)"
Much easier to have confidence in a communicator that can admit to their mistakes and correct them. Bit of a novelty in the climate "debate"! I felt a bit more optimistic after watching the video.
Now she can delete this one too and admit she was wrong about EU being 2.3 above pre-industrial in 2022 because they are two different things. Then she can remove the lie that we can continue "decarbonising" without hurting prosperity because we improved efficiency once. Like eating less, that does not work indefinitely.
@@tuberroot1112 sorry, accusing someone of lying when they have just demonstrated a willingness to admit and correct errors is the sort of adversarial partisan rhetoric that indicates further discussion will be unproductive.

This is why you are one of the Best Scientists on TH-cam Sabine.

I hope the algorithm doesn't hurt you too much (and no one has control over it) but please know that this is why we appreciate your content so much. Your desire to be 100% scientific no matter the cost.
Volcanoes here near the Andes, apart from earthquakes, sometimes one of them starts emitting smoke. It definitely lowers the temperature of my city at 200km away, pacific coast.. More than one month smoking and it went, nice, because here at that season the temperature is over 30º C, and it went down to 26º.C.. Absolutely cloudy... But those particles... Lots of ash reached us, cars were covered with that, also plants, like pastures for farm animals
Another very interesting and very understandable video, thank you.
It would have been interesting to add something about the cost of the various CCS and C removal methods, and in case of 'artificial' methods (i.e. other than vegetation/biomass) the energy requirements.
And with regard to stabilizing temperatures after net zero, I have doubts about that: the delayed temperature response might be (much) stronger than the effect of the slightly decreased CO2 level.

@@clayed3311: CO2 is a very good thing... in the right amount and in the right place. Plant's like the CO2 for growth but PLANTS HATE the excessive heat, drought, fires, and floods the excess CO2 is creating.
Hi Sabine, I´m a Californian Hyperion tree celebrating that finally a youtuber says hello to us 🌳🌲
Also, some nations are fudging the numbers. For example, Canda doesn't count emissions from bushfires as it isn't manmade however they count the carbon absorbed by trees (which isnt manmade).
Those sneaky Canadians ! And I heard somewhere that Albertans are almost as bad as Canadians !
@@grindupBakeroh? I thought it was us Quebecers? 😂❤
Lol, you think they aren't manmade.
Another point is that carbon removed by trees is only temporarily removed. Eventually, the tree dies and rots (or lately, burns) which liberates the carbon again.
We are removing a lot of trees here in Australia so that we can build renewable energy farms.
Show me the evidence. I see many wind farms and solar PV farms in South Australia and not a single one was built on ground not already cleared over a century ago for farming.
It's like digging a hole and filling it back in at the same time, and changing the definition of what ground level is.
Very well done, Sabine. The very best breakdown produced to date. Planet Wild, I will subscribe to. Very practical.
Sabine, thank you. I really enjoy your communication of science.
I am curious though specifically about the reduction in greenhouse emissions in Europe and North America, why is no mention ever made of their transfer of poluting industries specifically to China and other parts of the world? How much of the coal powered electricity genration around the world goes to produce goods for Western consumption?
SShhhhh, the media doesn't want to talk about that because then China wouldn't be gaining an economic advantage over us.
Who exactly is forcing the CCP to pollute as much as it is? It CHOOSES to operate dirty industries.
Virtue signaling. Australia ships coal to China, and doesn't count that in their country's emissions.
There is mention. You probably didn't notice. I knew of this transfer decades ago. China was building coal-fired power plants at the rate of one per week and both China and India vowed to raise the standard of living of their people by burning coal at large scales.
@@solconcordia4315 There were no mentioning of Europe and US deliberately moving "dirty" production to China and other developing countries still comsuming major part of products from these factories. Moreover there was attempt of scam with carbon tax wich for some reason should pay factories and not consumers of the goods :) Let it be consumers and then they will be more cafull with chosing what to buy and producers will be competing in lessening emissions :)
You talk about a possible decoupling between economy and energy, but if greenhouse gas emissions have decreased in Europe and the United States it is because these countries are deindustrializing. And if GDP increases it is thanks to debt. In reality there is no decoupling between economy and energy. What we no longer produce by polluting we import from countries which continue to generate greenhouse gases.
i just love it how academics, politicians, and others who have little problem with keeping their jobs or paying for their food, accommodation or fuel seem to think that the economies appear to be doing fine.
economies and personal wealth and health is being rapidly destroyed.
Just saw it, but I'll let it run in the background anyways, for the algorithm.
Haha. I watched a good portion of the other one. Can I get a refund Sabine?? Merci
Thanks, much appreciated.

@@MR-backupthe problem is, they have always do that, at the rate they have always done that, and only that "waste" which did not decay back into the carbon cycle was sunk carbon.
If you account for all the time and how very little amount of life ended up as hc chains, that we then burnt for (~20% of the) energy content... You will notice the math is that direct photons via PV panels are about 4 orders of magnitude more efficient.
Coupled with the cosmically tragic rate that we have been burning those handy HC chains, and you'll see that simply stopping the combustion, IE: net zero. Won't come close to re-sequestering that which we've liberated.
We will need to over produce via renewables (which is actually quite easy), and then deploy the majority of that towards artificial sequestration.
This gets us back to a pre industrial carbon cycle in balance, maybe. And at the end so much excess energy that space might be a good place to spend it by lifting some mass out of our gravity well...
@@MR-backupIt is covered under Biochar😉 Although its impact is not fully understood and the produced amount is used again, instead of being buried in the leftover pits of lignite mining.
We also could refill the Ruhrpott, limiting the forever costs.
I'm not sure I capture the difference between the two. Technically identical but used in a different way?
Thank you Sabine. Another clear and well researched video, on a topic that is as muddy as it gets. An effect which is not much discussed, though, is the contribution to CO2 removal by increasing vegetation growth resulting from increasing atmospheric CO2 concentration. I have no idea weather this factor is relevant, or how to quantify it, but I would be interested to know.😊
It's a bit of a self-correcting mechanism. The tree line is moving further north. The world is becoming more green. I'm personally not nearly as worried about the "climate" as I am about actual polluted waterways and such. I care much more about loss of habitat and the interruption of migration routes etc. than I am about how much CO2 is in the atmosphere. I think it's horribly missguided for us to care almost exclusively about CO2. I think it is a clever misdirection, and I think most people fell for it.
Another major tipping point is when frozen CH4 clathrates begin to thaw releasing methane plumes off the arctic seabed. 100x more potent a greenhouse gas than CO2 within the first 5 years. Growing evidence is showing as the arctic seas warm, the concentration of thawing methane hydrates is rising significantly as well. (Sharpova et al)
Up to 2000 gTonnes of CH4 has the potential of being released.

That NSO definition is agony to read. I am envious of you putting in the work to extract the sense it has.

Hey, I'm experimenting with making biochar for my garden! Very cool seeing that come up here.
DAC needs a gigantic amount of green energy to operate in a climate-relevant way. For larger DAC plants in planning, we are talking about the world's largest solar plants or even nuclear power plants and then of course the question arises why we need all the resources for carbon negative emissions if we don't even manage to decarbonize the energy sector.
DAC is a distraction because every kWh of renewable energy used for DAC removal displaces that same kWh of energy that could be used to power the grid therefore keeping carbon intensive electricity generation online.
The only way DAC makes sense is if we first decarbonize everything that's not super difficult to decarbonize.
Perhaps spell out the abbreviation the first time.
Yeah, DAC won't work without first doing the simple things. But BECCS and biochar should work. Though thay are limited to the amount of biomass we can get. BECCS also partially solves the energy issue. Maybe a worthwhile shot?
I agree that carbon capture (DAC or otherwise) isn’t an excuse for continuing to burn fossil carbon. But I’m good with doing early research and experiments on it now, so we can apply it once we have decarbonized the energy system and can build out surplus clean energy.
See, this is why I trust your word over the countless others on youtube who talk about similar topics. Not many are willing to admit and fix their mistakes and accept that there will be a downside in views as a result of it. Although I think with you, people, like myself, will rewatch it to see the ammended version.
Another great contributor is "Just have a think". He focuses solely on climate issues and takes the science really seriously as well.
In 2023 planet earth breached 1.5C ~100 times compared to the 1880 baseline or 1.7C when compared to the 1750 baseline (whichever is more convenient). The numbers the IPCC reports are so insanely conservative.
Why aren't we talking about feedbacks and tipping points (AMOC, antarctic and arctic sea ice loss, desertification of boreal forests and so on). Do people know we've lost 80% of the volume of Arctic sea ice in the last 40 years?
What about biodiversity loss (70-86% reductions in insect populations over the last 50 years etc)? Poisoning of oceans, rivers, lakes and seas with toxic chemicals? The poisoning and overheating of oceans has reduced the ocean Ph to ~.79-.80 acidic enough to dissolve calcium carbonate shells of plankton and other sea creatures (hence why we've seen 50% reduction in their presence over the last 50 years in addition to many other species including coral reefs). All of these factors are symptoms of human population overshoot... the human species' innate need to dominate and destroy every ecosystem it comes into contact with. When will we have enough? And when will we stop having Carbon tunnel vision?
@@gregelliott1948 These are all important factors. However, I'm afraid that you have bought into entirely backwards and counterproductive solutions. The solution is abundant, safe, clean, cheap energy, to raise everyone out of poverty to decrease birth rates, and to have enough spare cheap energy to maintain high levels of environmental protection. I'm afraid that you believe in the wrong and counterproductive "solutions" of keeping humanity in (energy) poverty.
The video is improved, but it is not actually fixed. Unfortunately, Sabine did not crunch the numbers, so she mistakenly believes that carbon dioxide is taken up only "slowly" from the atmosphere by natural processes, and that if we achieve net zero the levels will just "slightly decrease." In fact, if we achieved net zero, the atmospheric CO2 level would be falling even faster (slightly faster) than it is now rising.
Averaged over the last 10 years, the atmospheric CO2 level rose only 2.45 ppmv per year (= 0.603% per year). The reason I say "only" is that human CO2 emissions averaged more than 5 ppmv per year over that same period! The reason for the large difference is that natural CO2 removal mechanisms (mainly terrestrial greening and ocean uptake) are removing more than 2.5 ppmv of CO2 from the atmosphere per year.
So if we were to achieve "net zero" today, the atmospheric CO2 level would not plateau (as many presume), nor would it only "slightly decrease" (as Sabine supposes). Instead, the level would fall rapidly, at an initial rate of about 2.55 ppmv per year (though the rate would decrease as the level declines).
That decrease in CO2 level would quickly (in only 10 to 15 years) cause the current radiative imbalance (0.3±0.1 W/m²) to go negative, at which point global temperatures would presumably be falling, rather than rising.
What's more, natural CO2 removal mechanisms accelerate by 1 ppmv per year for every 40 to 50 ppmv increase in the atmospheric CO2 level. That means if our emissions were to remain at the current rate, the atmospheric CO2 level would rise by only about 100 to 125 ppmv before plateauing, because natural CO2 removals would then equal our current rate of anthropogenic CO2 emissions.
That 100-125 ppmv increase would represent just 1/3 of a "doubling" (log2(533/420)=0.34), compared to the 58.5% of a doubling of CO2 that we've already seen (log2(420/280)=0.585). That would eventually yield perhaps 1/2 °C of warming (compared to about 2/3 of the 1.15°C of warming we've already seen [WMO estimate] which is believed to have been due to CO2).
Inasmuch as the 1.15°C of warming we've already seen (since the late Little Ice Age) has been generally beneficial, there's every reason to believe that another 1/2 °C would also be beneficial, or at least benign.
@@gregelliott1948 wrote, "In 2023 planet earth breached 1.5C ~100 times compared to the 1880 baseline or 1.7C when compared to the 1750 baseline (whichever is more convenient)."
[1 of 10]
The WMO estimates that global average temperature has risen by 1.15 ±0.13 °C since "preindustrial" (late LIA 1800s). To put that into perspective:
● 1°C is the temperature change you get from an elevation change of about 500 feet.
● At mid-latitudes, 1°C is about the temperature change you get from a latitude change of about 60 miles.
● 1°C is a little less than the hysteresis (a/k/a “dead zone” or “dead band”) in your home thermostat, which is probably 2-3°F. Your home's “constant” indoor temperatures are continually fluctuating that much, and you probably don't even notice it.
● In the American Midwest, farmers could fully compensate for 1°C of additional warming by adjusting planting dates by about six days.
*Note:* Growing ranges for most important crops include climate zones with average temperatures that vary by tens of °C. Major crops like corn, wheat, potatoes and soybeans are produced from Mexico to Canada. Compared to that, 1.15 °C is negligible.
What's more, the warming is disproportionately at chilly high latitudes, where it is unambiguously beneficial.
Thank you for your work to educate us!! I learn something new every time i watch your videos.

I think we need to make seaweed and mussels massively more popular. These are naturally carbon negative, taking up carbon from the oceans and have no inputs other than the ocean itself.
It's quite bizarre that Sabine talks about China's emissions without mentioning that in per capita emissions, China is the 15th polluter, behind Canada, Saudi Arabia, the United States, Russia, New Zealand, Australia, Germany, Japan, among others. Also forgetting that China is today the so-called factory of the world, therefore, if we consider the consumption of Chinese products in these other countries, this attribution of blame becomes even more discrepant.

Very informative and smart video again Sabine. I may have missed it at the start, however I didn't quite see the connection between CO2 and world temperatures. What is the relationship? Is it linear, or asymptotic, or exponential?
Has there been a relationship between CO2 levels and world temperatures in the past, or is it just a new thing?
Also I didn't see any mention of the benefits of fossil fuels and their importance to all industries.eg pharmaceutical, agriculture, transport, telecommunications, building, infrastructure etc.

Sabine you sweet summer child. Our overlords are not really concerned about climate change, but rather about severely reducing humanity's future.
@viktorfunk1819 History shows us that a society that lives in fear of the security of it's future can be easily controlled. The more esoteric and obscure the fears can be, the more easily they can be confused and accept irrational fears and even more irrational solutions to their invisible dangers. The "overlords" know that they are safe behind their closed perimeters.
We know how horrible climate change is. When all the wealthy fly their personal jets to every meeting, instead of doing virtual meetings. When they talk about the rapid rise of the oceans, then buy beach front property. When they shift manufacturing out of countries with good waste control measures. To countries with horrible waste control measures. Maybe we could get another celebrity to tells us how we all need to do our part. Right before they jet out to their private yacht.

As far as I know "Net Zero" is just the same as the expression "Carbon Neutral" which used to be in use a lot some time ago. Of course any 'net zero' or 'carbon neutral' condition implies a steady state level of carbon dioxide, without actually defining what this level is, or what level is acceptable.
It does actually... "net zero" makes sense when you take into account the whole life cycle of something.
For instance... A wood panel for a building might have a negative impact if the wood is mulched at the end of it's life and more trees are planted to replace those cut down to produce said panel.
It's not impossible but it's also not feasible that EVERY single industry would plant enough trees to offset their emissions. Therefore we need to have a system that makes it expensive to pollute as an incentive to not do so. At the end of the day all you need is that everyone reduces emissions as much as possible and someone compensates for the remainder.
My point is that with equal rates of output and input there is a steady state CO2 concentration which persists in the atmosphere. This will tend to be close to the level at which carbon neutrality of the whole economy is first achieved. What this level is, would have to be adjusted (reduced) by periods of greater input than output. The main purpose of economy-wide carbon neutrality, is to stop the CO2 level rising any further. There are many other practical problems too, planting trees uses land area and there is an increasing pressure on the use of land because of the growing global food shortage which has been causing a long-term rise in global food commodity prices. Biofuels have caused problems by competing for land use with food production. @@pedromoura1446
Sabine your interpretation's are well presented and brilliant. When I heard the proposal for Carbon Removal by burning Trees having capturing emissions', I thought this is denial at it's worst.
What's clear at this point is that no one has a clue to real solutions or the possible consequences of those solutions.
Sure they do. It's not that complicated. The fossil fuel industry has a $4 TRILLION a year stake in keeping the fuel burning and that is having extremely negative consequences. Burning less fuel is the only way to mitigate the damage.
@@lrvogt1257And the consequences of burning less fossil fuels?
@@olibertosoto5470: Less CO2 emissions and slower temperature increases... which is the primary concern now. Freedom from dependence on OPEC+ and the FF companies etc so less ability for them to threaten, coerce and bleed us of cash.
It would be interesting to hear your thoughts about the energy needed for carbon removal from the atmosphere.
Or the energy requirements for the Green New Deal. They have to be more than what "green" energy can provide. And then there's the question of how much ecological destruction we have to do in the name of green energy in places that are out of sight of the voters. And then there's the question of how much of green energy relies on oil based materials to keep weights down on green vehicles. The questions go on and on but we're dealing with a religious movement not science so everything is answered by our having faith in our leaders.
Just to make i clear, I think we should abandon the use of fossil fuels/oil in the long term, or at least the burning it. Obviously not by destroying nature elsewhere. I just don't believe carbon removal from the atmosphere in a substantial amount, so it has an impact on global warming, is feasible...
More than the energy it took to put it there.
The most energy efficient method is to not dig it up and burn it.
@@Tailspin80 That's exactly what I suspect to be true!!!
Carbon dioxide removal could be something useful to do with excess electric power. In Australia, excess solar panels mean that power prices are zero while sun is shining.
The construction of solar panels has a cost which generally offsets the benefits you'd get from their existence in the first place. There's also not enough resources to construct enough solar panels to generate enough power to solve any real issues.
@@rusty6172power that is generated must be immediately used or store. At certain times a day, especially when using green energy, there is a surplus. It could be used to generate sodium hydroxide, which can be used to remove CO2 instead of being wasted. That was my point
@@stevenpace892 So how much you pay for electricity in Australia ? In Canada it has never been more expensive
@@dmitripogosian5084 it is expensive except when sun is shining. Government incentives cause so many solar panel installations that there is excess power.

An excellent video. Very balanced. I feel you missed a massive opportunity by not mentioning capture through regenerative grazing techniques with ruminants. It's been proven to be highly effective at increasing soil that can easily capture huge amounts of carbon.
Interesting. Is there any chance you can drop me a link or something I can look up and check that out?
I had a feeling all that had been debunked - more propaganda from the meat producers. Soils can and do regenerate very well without grazing by animals, and vegetarian diets greatly reduce carbon emissions, (typically 50-75% reduction for vegans), water use and land use.
regenerative grazing is a canard, it sounds good on paper but requires way too much land
@@nicolasgirard2808 it can allow 2-3x as many animals per acre as traditional grass-fed techniques. So, no, it's doable especially if we can utilize more nutrient-poor monocrop lands for it to provide more nutrients for humans.
The problem with this is that these are all temporary solutions. We're not capturing it and storing it away permanently, we're just temporarily storing all the emissions in the soil/grass/trees. As soon as they die and start decomposing, they release it all back, both methane, CO2 and NO. This is a temporary solution to buy us time. And we definitely need those, but we still gotta recognize it's only temporary.
Mechanical Engineer here...quick note on your comment about combustion. It is true that the problem with combustion is the CO2 produced from combustion and not the combustion itself. However, there are very few (if any) feasible combustion technologies that do NOT produce CO2. The only process I can think of off the top of my head would be hydrogen combustion using gas turbines, which are extremely fuel flexible. But this reintroduces the problem of production, storage, and distribution of the hydrogen which is not necessarily always green, or even blue. This is probably why Greenpeace and the EU are so fixated on the elimination of combustion processes.
Thanks for correcting your mistake. Appreciate your honesty and your dedication towards spreading good science :)
I feel like I've learned a lot about things that are not Kermit the Frog today. Hopefully, Sabine will explain what is a Kermit the Frog in a future episode on green tech.
It's not easy Being Green.
😂
Nice to know that Sabine is hip to Kermit the Frog.
I agree with your basic premise. But I think talking about other ways to conserve energy would have been better: public transport, insulation, grass fed beef, etc. And the problem is not just CO2; it is also heat emissions from combustion. But you are very correct; we are not on target to prevent climate consequences.
11:09 wow , a Mortal Kombat easter egg reference . Of all the things I expected to see in this video I never expected THAT.
I loved the look on your face in an old video when you asked the climate change modeling expert what happened when they modeled the point of no return global warming and the climatologist said we never tried to model it.
Plenty of evidence that the natural world has negative feedback loops that keep things in relative balance. In short the idea of a “point of no return” is contradicted by hundreds of millions of years of data.
@@sirrathersplendid4825negative feedback curves nicht weiter as follows: more CO2, it gets warmer, Vegetation spreads further, especially in northern regions were there is sufficient landmass, vegetation takes up CO2 (creating wood mass), this CO2 is extracted from the atmosphere.

@@xheerioyes. Plus 2 more negative feedback loops … most importantly, CO2 causes accelerated vegetation growth & ability to survive more arid climates. Secondly, all precipitation originates from evaporation. By increasing evaporation through higher temperatures, this increases the rate of precipitation which also increases vegetation growth rates.

note: *We can convert sodium chloride to sodium hydroxide and hydrochloric acid using some surface ocean heat and solar panels. The sodium hydroxide can be returned to the oceans to reduce acidification; hydrochloric acid can be used to accelerate the weathering of olivine minerals. The neutralized CO2 is stored as sodium bicarbonate in seawater where it is harmless.*
Most CO2 emissions end up in the oceans. There could be cheaper ways to introduce a basic substance able to mineralize dissolved CO2. It is like the accelerated weathering of olivine sands that other scientists have suggested.
That's really interesting. The only problem I see with it is that it would not generate money for whomever does it, and it might actually be quite expensive.
Sodium bicarbonate in ocean water harmless you say.
I don't have a degree in biochemistry or ecology but I am going to call that bullsh¡t anyway.
Chloralkyl electrolysis with raw ocean water is basically not possible. Perhaps desalination plant byproduct brine could be treated so that it would be concentrated and clean enough for electrolysis. That process would use up some of the desal water. Then the only hurdle left is the massive energy cost of electrolysis, and the cost of building and operating the chemical plant, and transportation of the acid, and then you have to grind up mountains of olivine, and hope that there are no unintended consequences to any of this.
My favorite foolproof plan in a similar chemical line of thought is the brute force carbonate method. Dig up limestone and heat it in kilns to produce a concentrated CO2 stream and quicklime. It is feasible to take that concentrated CO2 stream and pump it into basalt deposits where it forms chemically stable bonds very quickly. Take the quicklime and grind it into dust and spread it over the ocean, pulling carbonic acid aka CO2 out of the ocean, which will then pull CO2 out of the air. To pull enough CO2 out of the air with this method would require mining on roughly the same scale at fossil fuel mining today - that's no surprise from a thermodynamic perspective. It would also requires thousands or tens of thousands of large nuclear power plants to provide heat for the kilns.
The biggest issue is trying to educate politicians in basic science. 99% don't understand and just listen to activists - hence the mess we are currently in.
@rick I agree. The problem is they DON’T listen to climate scientists or activists. They listen to oil & gas money (& ICV, rail, banking, media & other industries coordinated by the far right).
All the scientists whose research is taken as a basis to harsh policies that make our quality of life worse (by for example forcing EVs to us as a replacement of internal combustion engines) should be held responsible for their claims. So, if in the future their models would prove wrong, they and thwir heirs should be financially fined for the damage they caused. Such a piblic decision would bring more scrutiny into climate research and policies. In short: put your (and not ours) money where your tongue is.
I’m not sure having a quantifiable goal is helping anymore based on the results so far and the muppets we have in charge.
Also I wonder if the natural processes are going to start to degrade as well as the oceans become more saturated and the forests get cut down or die?
Aw yes. When will "they" cut down all the trees? I mean, how stupid of "them" to just keep cutting and cutting and never replanting. Don't understand why all the trees haven't all been cut down already. What? Do you mean to say there are more trees in continents with active forest products industries then there were 100 years ago? Can't be. This is just lies from shills for the forest products industry. After all, "they" are just too stupid to know that if they didn't replant more than they cut that their most important raw material would disappear. And we all know they are too stupid to realize that. Now you be a good boy and don't use paper or wood. Save a tree, y'know.
Yes they will start to degrade. Deserts do not store a lot of carbon.

I think you are not taking into account the legislation that has passed in the US in the last couple of years. The Chips and Science Act, the Infrastructure Bill, and the Inflation Reduction Act contain massive incentives for GHG reduction and development of strategic clean manufacturing in the US. I agree that natural carbon sinks will degrade to a certain extent, but I don't think it will be enough different to worry about.
Great presentation. Capturing CO2 from the air is great. To explain it to my grandchildren I asked them to spill 250 gram of Smarties in grandmas kitchen and then collect the Smarties. One grandchild, a smart girl, proposed NOT first to spill the Smarties...

Biggest issue hampering reaching netzero fast is the influence of the climate lobby & activists going all-in on renewables and villifying natural gas and nuclear, even as intermediate steps.
Sure, natural gas does have co2 emissions, but vastly less than coal and lignite, so switching to gas instead of coal/lignite would be a massive win already, especially for developing countries who might not be able to purchase a >15 billion nuclear plant. The West decarbonizing while developing countries are weened of coal into gas would still be a great benefit to total emissions.
As for nuclear, it's criminally insane we're not building at least a single plant in each Western country, it would save so much emissions it's hardly fathomable. Since it's a complete different sport than building windmills and installing PV, there's little competition for resources & personnel while at the same time it's a hedge for the winter times when there's less solar available and sometimes weeks with little to no wind.
But that only addresses the emission part, as goes for capturing, it's too complex and too politicized for most people to understand or support a certain method...so there's too much division to even decide on a path of direction., let alone make it as efficient as possible.
So much this.

You dozy animals are not fit to comment.
Sometimes it's an advantage being late at watching a video. And I agree with you, especially about the importance of carbon dioxide removal instead of capturing and storing CO2.
Sabine is one of the best, if not the best, science educators I know about.
Nah climate science is pseudoscience like 50% of all sciences. Most scientists don't even understand causality. Sabine is one of them.
For instance: The economy didn't grew 61%. GDP did but doesn't include for instance inflation. If GDP has risen slower than inflation your economy is shrinking.
Also Chinese numbers of GHG per produced good should not be trusted. CCCP numbers have been controversial for years.
It's only the chinese 'numbers' that have come down. The world change is marginal which doesn't add up too.
Anyway green deals hurt the economy as you can see in Germany. It's in the numbers of spending power too. Big problem of less aerosols from fossil fuels is that it will not block sunlight which leads to more global warming. It's a stalemate position. Best thing you can do is use loads more seawater and build so can handle climate change. Check Judith Curry.
Regarding China emissions and their importance, it should be noted that China industry produces mainly to meet the demand of Western countries. In fact, county emissions charts that don't take into account the import/export balance are quite misleading, because they hide the fact that western economies have massively outsourced their production to third countries.
Correct.
Great point
They still have like 1.3 billion people.
Unless you want to institute global trade bans, that won't change. China emits far more GHG per $ of production than almost any other country. so they're not just more inefficient in the absolute but also on relative measures.
@@krishnam1 if the West wants to stop China's pollution it can do so easily enough by stopping consumerism.
Not only that. It's very hard to go green while simultaneously fomenting wars in this or that part of the world. It's not very hard to understand that going green is the last problem which worries soldiers on the battlefield.
Precisely. If the world powers were serious about climate change they would put a moratorium on War making.
Wholesale capture is, quite literally, a pipe dream. Energy efficiency is about 50 to 100 times cheaper for the same amount of carbon reduction. And energy efficiency, once carried out, pays back within a v short to reasonable time.
Sabina, thank you for your sense of humor. Such a serious situation, and you remind us of the beans…👍🏻
Beans may become essential as THE source of protein, other than insects, when all livestock gets obliterated. But I'm sure monsanto will develop beans that don't result in methane.
Climate change is not fun for the people affected.
Why no mention that temperature increase due to CO2 is logarithmic, or that charts over hundreds of thousands of years show CO2 increase lagging temperature increase, or natural short term climate changes (decades or centuries) aka. the Little Ice Age or Medieval Warming period, or that plants thrive on CO2, or that if CO2 levels get too low plants will die, or that fossil fuels will likely run out over the next century? A logical approach would be to transition coal plants to natural gas, followed by natural gas to fission nuclear, and then fission nuclear to fusion nuclear. Shutting down fossil fuels with no real replacement will kill billions of people.
Because its wrong or not relevant.
Oh dear. I hope that the climate sensitivity is actually on the low end.

Liebe Sabine. Very good analysis. Your conclusion on Carbon removal might be falling short. It's the economics. "economics" should not be confounded with kapitalism. I refer to economics as the best universal scale we have, even if it is flawed. And it's crucial to quantify and do the maths, as I think you do.
Well, the economic analysis tells us there is a problem with carbon removal. It's too expensive. This doesn't mean bad kapitalists have to be bled to provide the necessary cash to do it, it indicates that it might not be feasible to do.
For instance, please look at Simon Michaux's analysis on lack of mineral resources for the green transition.
I.m.o. we are simply running out of cheap energy resources, and the planet cannot sustain our consumption. So besides global warming, we might have a much bigger problem of outgrowing the resources of our planet. Energy is also massively required to feed the world population, it's not just that you cannot recharge your smartphone always and everywhere. This is a very serious issue. And if, as is very likely, global warming will kill people, this will actually help the bigger problem we have.
Yet, and unfortunately, it is likely that the depletion of cheap energy will outpace global warming, and that we will be soon fighting a gerilla war for food and food-producing living space, before we will seriously reduce net carbon emissions.
Nevertheless I wish you the all the best in 2024!
