    I was a little surprised not to hear anything about methane. As you might know methane emissions up to 2005 can be explained by pipe leakages and fracking, but from 2006 on there's a growing gap between direct anthropogenic emissions and the total emission. Obviously, the additional emissions started from tropical and subtropical wetlands, with thawing permafrost kicking in later. And as the Swedish-Russian Expedition on the scientific research vessel „Akademik Keldysh“ proved that not only the thawing permafrost on land releases methane but also the shelves in the coastal area release bubbles of methane/methane hydrate to the surface of the sea.
    We know from the Earth's history that methane played an important role in temperature changes and is capable of causing a termination event. On the other hand, it is a functional chain of cascading classic positive feedback loops, for example, it doesn't only increase the thawing in Antarctica directly, but also increases the melting of Ice in Greenland, which slows down and finally kills the thermohaline motor of AMOC, causing a colder climate in middle and northern Europe, rising the sea level in Europe another 40 to 80 cm above the predicted levels, and since the heat transport from the southern to the northern hemisphere by AMOC will fade away, the warmer water will not only amplify the thawing of Antarctic ice in addition by the direct impact of atmospheric methane but also puts more heat and water vapor in the atmosphere, causing more extreme weather events.

      Methan is not part of the modeling. Its a known unknown

      LPG has just been found to be more polluting than coal, from 35 to 235% more depending on the method of transport. Gas consumption has almost doubled since 2006.

    This topic is super important, it should therefore have way more views. But it doesn't.
    Just to entertain myself a bit, I was asking chatGPT4 what is the fraction of 2200/8,000,000,000 compared to the distance to the moon.
    and it's 0.275 micrometers.
    That's pretty much how I feel about our progress as humanity towards preventing climate Armageddon.

    I've got a big question. Considering how much methane some complete psychopath just explosively released in the Baltic, how screwed are we now? because that kind of thing has a tippy kind of effect all things considered in the arctic temperature wise?

      There is a recent study that showed Methane levels in the atmosphere increased during the covid lockdowns even though the human emmisions went down. This was before the pipelines where damaged. But the study showed that the northern permafrost melting was releasing more methane than we cut our emissions during covid. Which suggests it is becoming a reinforcing feedback.

      @@DanA-nl5uo yeah, I just caught up with that. I can see why Natalia Shakhova was so visibly upset when predicting this a few years ago. I think we're basically into panic mitigation territory.

      It was surely the USA that destroyed the German/EU/Russian pipeline that was fully loaded with natural gas from Russia as was publicly promised by both Nuland & Biden would be done in their different public appearances earlier in the same year before the Russian invasion of Ukraine. Moreover, the ex-Polish Minister of Defense married to the US writer Applebaum publicly thanked the US for blowing up the pipeline in a now deleted tweet (of course). Moreover there was the publishing of the text from PM Truss to Blinken right after the explosion stating "It's done." More evidentiary, is the recent German government report that there is no evidence that Russia sabotaged it. As for how much methane was released, a Chinese study estimated about 1 year's worth of total global methane was released by that state - terrorist perpetrated attack which also makes it one of the greatest one-time environmental crimes in human history. Oh I forgot, that Nuland just bragged to Sen Cruz that Nordstream was a "hunk of steel at the bottom of the sea" which begs the question of why she would be saying that if she knew Russia did it is the obvious question to be asked. Even more persuasive is that Russia only had to turn off the gas if it didn't want to export that gas at any time and visa versa which was a leverage card that it surely wouldn't have self-sabotaged as it has done with the natural gas pipelines that transport its gas across Ukraine which they haven't blown up either.

    Whenever these people start with the “tipping point” schtick, best hold on to your wallet. In a complex chaotic system, tipping points don’t, cannot, exist.

    If you ever use the term "positive tipping points" just once. Just once. I will visit the forest when it's dry. And then there will be a small incident that will lead to things.
    Tell your friends to shut the fu*k up about "positive tipping points". I am sickly tired of those lies.

      Why do you think human behaviour is inevitable, only in one direction? Most people don't know, by design, the real problems, just so profit models continue but yeah it's changed before, last time 90% of species died, so what do you mean "the clmate is changing...?
