A new analysis by Hansen and colleagues concludes that both the impact of recent cuts in sun-blocking shipping pollution, which has raised temperatures, and the sensitivity of the climate to increasing fossil fuels emissions are greater than thought.

The group’s results are at the high end of estimates from mainstream climate science but cannot be ruled out, independent experts said. If correct, they mean even worse extreme weather will come sooner and there is a greater risk of passing global tipping points,

Evwrtyhings on course for the collpaee if civilisation under the weight of human stupidity :)

    Didn’t even register your username.

    Go look up how the arctic permafrost is rapidly melting, releasing ungodly amounts of methane, which is roughly 70x more potent a greenhouse gas than co2.

    A couple years ago now I first saw that rivers in Alaska were being reported as running a kind of bronze/orange color… go look up ghost/zombie forest fires, where forests in siberia, alaska and canada are burning down from the inside out, from underground methane that catches on fire.

      I love all the stuff you have posted, I just have one small correction, methane has about a 30x stronger GHG effect than CO2. I also believe we are fully cooked for all the reasons you laid out. It’s honestly keeping me quiet a bit more calm during the current shit show in the USA.

      Even in the worst possible case scenario with that, they will get 10-20 years of ruling at best before they are undone by their own hubris. I really think that in the next decades hurricanes are going to go ape shit and one will actually LEVEL Miami. I mean shit, with sea water rising and flooding skyscraper basements, eating away at concrete and steel, a strong enough hurricane could topple one right over.

        I saw 72x in the last article I read mentioning it, can’t find it, MIT says 84x CO2 for the first 20 years.

        In the first 20 years after it enters our atmosphere, methane will trap around 84 times more heat, pound for pound, than carbon dioxide (CO2), the best-known greenhouse gas.

        https://climate.mit.edu/ask-mit/how-much-methane-do-human-activities-put-atmosphere

        The point is that its kind of like a bullet:

        CO2 heats up the atmosphere up to a point, thats like a hammer being cocked back slowly while your finger is on the trigger.

        Atmosphere hits a certain tipping point, apparently it was about +1.5C, at that point the hammer swings and hits the primer, primer then ignites the much, much more powerful gunpowder.

        Gunpowder going off is what actually fires the bullet, sends temps and other feedback loops into overdrive very fast.

        Gun is pointed at our head.

        But anyway, damn the details, we do appear to be well and truly fucked.

        I keep laughing any time any news commentator says ‘history will look back at X and think…’

        There’s not gonna fucking be any history, any historians, 100 years from now, at the rate we are going.

          I literally looked it up before I corrected you but who fucking knows honestly. Maybe I did a piss poor job. Bottom line is, we fucked, bigly.

          I think the exact thing with all the news. In some morbid sense, those being killed now and in the near future are just skipping the line and avoiding the rush. They don’t have to see how truly UGLY it will get towards the end.
