The Net Zero Myth. Why Reaching our Climate Goals is Virtually Impossible

[@SabineHossenfelder]

Why do KZbinrs 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.

[@AquarianSoulTimeTraveler]

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.

[@namewastaken360]

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.

[@incognitotorpedo42]

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.

[@DrJon-zf2xo]

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.

[@J4Zonian]

@@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.

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.

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.

I understand why institutions focus on carbon dioxide, as it is easily quantifiable.

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?

[@ncdave4life]

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.

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.

I see that tree planting and use of timber for construction are listed under Carbon Dioxide Removal (CDR). I've been in favour of this for 35 years. It's a no brainer really. Why aren't there massive programs for this?

[@therflash]

Because over time the wood rots and turns back into CO2. Unless you burry the wood or turn it into charcoal and then burry the charcoal, you're not removing any CO2 long term. Maybe you do for 50 years or so, but sooner or later, the timber would have to be replaced and the old one would be either left to rot or burnt, both of which will turn it into CO2 again. But if you do burry the wood or charcoal, you're basically just producing coal and storing it back underground, thus doing the opposite of what the industrial evolution caused. In the long term, that's a very correct thing to do. But currently it still doesn't make any sense to do it today, while there are other people around the planet still digging other coal up and burning it. You get a much bigger bang for the buck if you stop those people digging coal first. If you try to store wood or charcoal underground today, then the entire industry chain involves digging coal to burn it in coal plant to drive an industry that produces charcoal and stores it underground. That would just be a circular effort getting us absolutely nowhere. Energy production from gas/coal/oil has to stop first, and then once we have excess energy, we can use that to produce synthetic gas/coal/oil and store them underground to finally undo this mess. Also, we first need to get rid of coal economy first, because if you capture CO2 and store it underground as wood or coal, who's to stop existing coal companies from just buying the land, digging it back up and selling it?

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.

[@pedromoura1446]

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.

[@bhangrafan4480]

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

[@Doc92IDH]

While I appreciate the integrity and attempt to be as accurate as possible, she wasn't wrong. If we stopped all anthropogenic emissions overnight, feedback effects mean that, at least for a short while, temperatures will continue to rise. The last bit of emissions will lead to a slight increase in temperature, which in turn leads to a slight change in water vapour partial pressure. This means increased water vapour, which itself is a greenhouse gas, which in turn increases temperature, which will loop until the effect equalises: kind of like how a spring continues to oscillate after it is released. Other complications include plant leaves thickening with increased CO2, which in turn reduces the carbon take-up from photosynthesis. Well known effect from greenhouses if plants aren't pruned regularly. In short, no-one can really quantify the effect, but we can be pretty confident that this will happen.

[@DeniseSkidmore]

Bioenergy also captures carbon via root deposition. The plant grows above and below ground, but we only harvest the above ground portion.

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.

The amount of co2 needed to be removed from the air is simply too much. Like, you can't really imagine the true scale of the industrial operation required to extract co2 from the air, and it's not likely to be possible to build an industrial co2 extractor that actually takes in more co2 than it costs to construct. We're talking about printing carbon piles that are the sizes of cities and then finding a place to store it; an entire ecological disaster on its own... and then that's just to cover 1 year of emissions (~40 billion tonnes of co2 per year at present).

[@colinmacdonald5732]

It's trivial to point out that the higher the concentration if the gas you want to remove, the easier it is to remove. If we can't economically extract CO2 from flue gas what's the chances of removing it from the atmosphere, where concentrations are 1000 times lower? The only method I see working is to use different soil tillage techniques. If you could put an extra one mm of carbon depth in the topsoil of farmland every year that would roughly to stop C02 increase in It's tracks.

[@kimlibera663]

My goal with industry is to extract from the ambient air or flue vent just for the sake of filtering the air out. There is no way to extract co2 out of the entire atmosphere & that is why net zero is a pipe dream. So pragmatically I just focus on mitigation rather than utopian targets. What I'm afraid of with the alarmists is that they would not appreciate any improvement; they are too focused on a target that one cannot hit. When I look at the emissions of sulfur oxides in the USA & how they have come down 90% I think that is a tremendous achievement. So if we stick to what is pragmatic we might get something done. I fear the govt taking away vehicles, stoves, furnaces all because they are obscessed with net zero. Add the filtration, there is likely to be improvement.

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.

[@markfabre7682]

I've always found your videos entertaining, educational, and thought provoking. Thank you. Current concern over atmospheric CO2 makes me wonder what happened in the past to cause increases and decreases in CO2 levels. After all, animals are not the only lifeforms on earth that have evolved over the past 500 million years who both adapt to and affect the environment. Looking at CO2 graphs going back before the carboniferous period, it appears back then the CO2 level was above 2,000 PPM and the earth was humid and tropical. Note that 2,000ppm would be harmful to most plant life today. This period saw the evolution of lignum and cellulose in trees allowing them to grow tall in dense forests (more CO2 storage per acre). As plant life died at that time, the bacteria that could digest this new lignum and cellulose had not yet evolved so the trees could not decay but became the coal we have today. The resistance to decay from lignum and cellulose in trees at that time allowed them to store CO2 from the atmosphere into the ground as coal causing CO2 ppm levels dropped to about where they are today. This might have continued until today except for the End-Permian Extinction 252 million years ago which was a terrible setback for life on earth wiping out 96% of marine and 70% of terrestrial life (including plants). Once again there was a surge in CO2 levels. Since then, it appears CO2 levels have trended lower reaching a practical minimum of around 200ppm. I say "practical minimum" because whenever CO2 falls to that level in the last 400,000 years or so, 2 things happen: 1) We have an ice age. 2) Plants die off because they are CO2 starved. Once plant life dies off and decays, CO2 levels rise again allowing the earth to heat up and the cycle repeats. This has been the pattern until we apparently (and unintentionally) found a way to break the ice age cycle by releasing CO2 prematurely. The unintended benefits are: 1) Plant life (including food crops) continues flourishing. 2) No ice age. It may turn out our unintended manipulation of CO2 levels has benefits few can comprehend and even fewer will admit. Don't read too much into my rantings. I'm not educated as a climate-geologist (geoclimatist?). I'm just a semi-retired control systems engineer who has worked in almost every industry and research field from fossil fuel to nuclear, fertilizer to foods, mining to chemicals, and magnets to gravity waves.

We have technology for that and it is called "farming" and "foresting". Carbon compounds formed by trees that become furniture, beams and floor are removed from the atmosphere and tend to stay removed for very long time. Higher levels of co2 in the air has increased both crops yield and trees growth speed quite dramatically already. At so-called pre-industrial level we used to be frightingly close to the point when plants would not be able to photosynthesize (if co2 concentration dropped further we would experience that as like what happened in Interstellar movie). Plants are the most effective at capturing CO2 (that is growing grains, fruits, vegetables and cellulose) at 10 times the current CO2 level so we have a lot of room. All of this was confirmed many times via greenhouse experiments that can be easily reproduced; you can reproduce it at your desk via large jar and small plant even.

"The rich" being the main problem here. In almost every country, the wealthiest 5-10% of households cause more total emissions (and in some cases FAR more) than the bottom 50%. This is one reason why a decently implemented CO2 tax (so a CO2 tax where every citizen is paid back the average amount) is very effective. It puts a price tag on emissions and rewards those who make eco-friendly choices (without even requiring them to know that it's eco-friendly!), while at the same time helping low incomes rather than making things even harder for them. For a millionaire, this for example puts a higher price tag on private flights or owning many heated mansions. This leads to some direct reduction, and to some redistribution. Parts of that redistribution also end up in the state's budget again (poorer people buy more => pay more sales tax) and can be invested to speed up the transition to low carbon energy and increasing energy efficiency (like building insulation standards).
