    The IPCC calculations were always criticized for being overly optimistic. Anyone following this debate knew that we would hit 1.5 C sooner rather than later.

    We are definitely going to hit 3 degrees in our lifetime, once the melting tundras release their methane store.

      If anyone is curious about what 3C looks like, here’s a solid video on how a 3C world would look.

      https://youtu.be/uynhvHZUOOo?si=yk8rvR1Bg3t4aKGe

      It’s 16 minutes so as a TL;DW: Not “extinction event” but extremely bad. Areas of the globe will simply become unlivable - and these areas tend to be highly populated. The resulting mass migrations and shortages of water/food will lead to conflict, often between nuclear powers. End result: humanity will keep on living, but it will be a significantly more deadly environment and a significantly more conflict-prone political environment. Economic collapse will hit major metropolitan centers.

      If watching the video bums you out try to focus on the absolutely bonkers cool sideburns the climate scientist has. Cheered me up a little. Like a handsome person telling you that you have a bad disease.

      Anyway, vote for climate-positive outcomes wherever possible and consider joining a climate lobbyist group. I’m a member of this one but I’m sure there are others.

        As if all that is not depressing on its own, there just a little less than half of the world that believe it’s a hoax. While they’re being cooked alive. And continue to vote for politicians that perpetuate the idea it’s a hoax.
