Atmospheric Levels of All Three Greenhouse Gases Hit Record High (theguardian.com) 143

Atmospheric levels of all three greenhouse gases have reached record highs, according to a study by the World Meteorological Organization, which scientists say means the world is "heading in the wrong direction." From a report: The WMO found there was the biggest year-on-year jump in methane concentrations in 2020 and 2021 since systematic measurements began almost 40 years ago. Methane levels have risen rapidly in recent years, puzzling scientists. Some blamed it on an increase in fracking in the US but this came into doubt as industrial emissions were not showing a similarly sharp rise.

Now the theory is that the methane rise could be caused by activities of microbes in wetlands, rice paddies and the guts of ruminants. Rising temperatures have caused the ideal conditions for microbial methane production, as they enjoy warm, damp areas. Carbon dioxide levels are also soaring, with the jump from 2020 to 2021 larger than the annual growth rate over the past decade. Measurements from WMO's global atmosphere watch network stations show these levels continue to rise. These greenhouse gases cause global heating, with the warming effect rising by 50% between 1990 and 2021. Carbon dioxide comprised about 80% of this increase. According to the WMO, carbon dioxide concentrations in 2021 were 415.7 parts per million, methane was 1908 parts per billion (ppb) and nitrous oxide was 334.5 ppb. These are respectively 149%, 262% and 124% of pre-industrial levels.

      Global warming isn't happening.
      The global warming, that isn't happening, ended in 1996.
      The global warming, that isn't happening, is caused by carbon dioxide from volcanoes.
      The global warming, which isn't happening, is not caused by carbon dioxide but by solar output (never mind that we have direct satellite measurements of solar output back to 1978).

      I don't know why people consider this insightful.

      The important question is not so much whether CO2 levels are rising (they are). And its not whether this will have a warming effect. The evidence is that it will - though observational studies suggest a fairly modest one.

      The important questions for those who are seriously alarmed about this, and urge action based on their alarm are:

    • What worries me is that Global Warming, while possibly being 'normal' along a mega-timeline, is right now in a confluence of an up-trend in the mega-timeline and that of our shorter timeline presence on the planet in an industrial culture, and that we discover our eliminating *all* of our contribution to that warming will be insufficient to avoid eventual climate catastrophe while we're still present. (Yeah, it's run-on, tough. I've read Proust.)

          Maybe it won't undo the damage, but we can stop the bleeding. In the zero emissions scenarios, there is almost no further warming [easterbrook.ca]. Why is this? You need to look at both Climate Sensitivity and Carbon sensitivity.

          It turns out that the two forms of inertia roughly balance out. The thermal inertia of the oceans slows the rate of warming (thus leading to further warming after we stop emitting), while the carbon cycle inertia accelerates it (leading to reduced warming once we stop emitting!). Our naive view

        • We already know that eliminating all human contribution to global warming will not undo the damage.

          We do? Based on what? We have to stop making things worse first and we have a ways to go to achieve even that. However, I have not seen evidence that the level of CO2 will not reduce back down to what it was before we started burning fossil fuels if we can just stop pumping GHG into the atmosphere. There are plenty of mechanisms to remove GHGs from the atmosphere the problem is that they are being overwhelmed by our rate of producing more.

            My understanding is that processes are slow on a human timeline. 1000 years is one number thrown around. More rain equals more weathering, takes time.
            There's also the chance that things like the melting permafrost releasing carbon and methane will keep happening for a while even if we become carbon neutral.

              CO2 would initially drop quite quickly if we moved to zero emissions as this figure indicates [wp.com]. The red line in that figure shows CO2 concentrations if we moved suddenly to zero emissions. We may expect to drop CO2 levels by ~20% by the end of the century if we move to net-zero emissions.

              It won't return near to preindustrial levels, but it will drop. The reason is that a significant fraction (roughly half) of our CO2 emissions are absorbed by the oceans, but this also takes time. We can think of this as

                There is a risk, but my understanding is that this is not expected to dominate. There is still time to put the genie back in the bottle.

                We are already over several tipping points. And while there is time to prevent the worst, there is no apparent will to do so. Hence things will continue to get worse. When the real scale of this will become apparent and undeniable, it will be far too late.

            Well, simple: You have not even the least clue of how climate works. Removing all that CO2 will not reverse the changes it has caused. If you actually bothered to find anything out, you would know that.

            • Removing all that CO2 will not reverse the changes it has caused.

              Based on what? Your say-so? Removing the CO2 will reduce the amount of heat trapped by the atmosphere causing temperatures to fall, more ice to form increasing albedo and causing more cooling i.e. a complete reverse of the process we are now seeing. What processes are irreversible? Yes, there are some changes that will longer to reverse than others, like reforming and/or thickening of ice sheets, but I've not seen any clear evidence that this will not happen given time.

      Actshually, cyanobacteria that converted the Earth's CO2 atmosphere to an O2 atmosphere were the most successful at destroying the biosphere. Almost everything alive at that point died from exposure to bacterial shit (O2).

    While I drive an Electric Car, and my previous car was a hybrid, and I try to do things that are in general better for the envrionment, I am not net 0. Because there are things I need to do to properly function in my society that are good for the envrionment.

    The same issues is with companies, they just can't stop burning carbon, and often many of the regulations that are proposed are too difficult for the companies to implement, however at the same time there is political pressure that they push to keep things the same thus making it harder and harder for them to do the right things in any sort of good time fame.

    Sure saying to close that Coal Power Plant is unwise, however politics had taken that unwise action as an excuse to build more Coal Power Plants, which make it even more difficult to close down, because they are new and modern.
    The Parisian winner take all Politics. Will either push to Close All The Coal Power Plants, or Just create more Coal Power Pants. Things like expanding the energy infrastructure for new power plants to be made to use different material, which is better for the envrionment, while keeping the existing Coal Infrastructure and modernizing it until it is no longer practical, and allow for a gradual decline of that particular source of energy as better cheaper sources will now be available.

    We still need Coal and Oil.... However we should really make sure we focus on diversifying our energy demands to include more clean sources as well. Until we have clean infrastructure that can stand on its own. And we will still probably want Coal and Oil, but less for Infrastructure needs, but for smaller individual needs.

      I agree with most of that but from the people that study this from a market perspective:

      We don't have enough copper. [msn.com]
      Building Lithium based batteries takes Lithium which has tripled in price in the past year. [barrons.com] It will become more valuable now that economic adversaries are the biggest refiners and miners and are going after holdings to increase their hold on that position. [fdiintelligence.com]
      While we have new, more powerful wind turbines being produced we still have NIMBY to contend with, especially offshore. [ocnjdaily.com]
      Oh, and Solar Panel production is again dominated by those who flood markets and undercut others. [energysage.com] In the top 10 listed, only two companies are outside of China.

      We can continue to go green or we do stupid things and make our economic and political adversaries stronger by betting the farm. My bet is to build a few more fission plants using new technology and then let things like Fusion and Hydrogen Fuel Cells/Production improve. Meanwhile, I'll invest a few grand and put Solar and LIFePo batteries in which will be good for 20 years, and no, I won't see an ROI anywhere close to the investment needed considering current utility rates. Or is that it, raises utility rates to say "hey, we can go green and save money?" That part is confusing to me because at least for me, other than being a good world person investing in Green doesn't make economic sense.

      H2O does prevent heat escaping. but not when it is a gas. It is when it condenses to form clouds that it keeps heat in. Especially at night

      • Wrong. Water vapor in itself is the biggest gaseous greenhouse contributor, by a very large margin. The effects of clouds are many and some scientists are even unsure whether they are a neat positive or negative. My guess is that it depends....

  • We are going to worsen that by ramping up the production of hydrogen. The more the merrier. Hydrogen seeps through its reservoirs into the atmosphere where it reacts with other gases, worsening the greenhouse effect.

    From the article at https://www.space.com/emit-instrument-international-space-station-methane-super-emitters [space.com]:

    EMIT has identified more than 50 methane super-emitters in its first few months of operation --- and that's not even its main job.

    A powerful eye in the sky is helping scientists spy "super-emitters" of methane, a greenhouse gas about 80 times more potent than carbon dioxide.

    That observer is NASA's Earth Surface Mineral Dust Source Investigation instrument, or EMIT for short. EMIT has been mapping the chemical composition of dust throughout Earth's desert regions since being installed on the exterior of the International Space Station (ISS) in July, helping researchers understand how airborne dust affects climate.

    That's the main goal of EMIT's mission. But it's making another, less expected contribution to climate studies as well, NASA officials announced on Tuesday (Oct. 25). The instrument is identifying huge plumes of heat-trapping methane gas around the world â" more than 50 of them already, in fact.

    Here is one data point that is surprising ...

    Until 2012, mean levels for CO2 were below 400 ppm at Mauna Kea since records started ...
    This year it is 421 ppm ...

    So it is increasing at a rate of ~ 2 ppm per year ...

    • Yup. Luckily for us the response is logarithmic, that's why they talk about doubling when discussing climate sensitivity. The reasons are well understood.
