    A decade ago, It was predicted that we would hit 1.5°C between 2050-2060, and even as recently as 2 years ago the prediction had moved forward to between 2030-2040.
    The next decade or two are going to be very… interesting

      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.

      what’s worse is that it’s actually 1.6 C

      it says in the article here

      Data released last week from Copernicus, a branch of the European Union Space Programme, shows August was 1.59C warmer than 1850–1900 levels, following a 1.6C increase in July.

        Yeah, it’s honestly horrifying to see the lack of reaction around the world. If you live anywhere near the coast, you better get the fuck out or tell your kids to.

          I’m already telling people to get out of Florida*. I expect multiple Katrina-level events over the next 15 years. “Florida refugees” is going to become a common phrase.

          Orlando might be more likely to survive than Miami or Tampa, but do you really want to be in the city surrounded by devastation?

          We, as humans, seem to have lost the ability to plan more than 20 years into the future. Florida is still building in areas that are going to be crushed, and the only reaction is from insurance companies.

          We’re not trying to prevent it. We’re not building any kind of defenses or contingency plans. We’re not encouraging people to move out. We’re not preventing people from moving in. In fact, we’re building new and encouraging people to move IN to Florida. It’s full on head in sand.

              Look at the percentage of these purchases that are foreign investors making cash offers and I think u start to see why the insurance companies leaving isn’t having the effect it should.

            Man I have like 5 family members and friends just move to Florida. They were tired of the high taxes and politics of California. At least they won’t burn in a wildfire though!

          It’s nice by the coast though, I’d just put aquatic pilings under my house and have a ruggedised shelter built into it. Even if I live to a hundred and fifty with all the ice melted my land will still be under less water than the intercoastal platforms we’ve been routinely building since world war one.

      Supposedly the new stringent heavy shipping emissions controls are having an impact on the greenhouse effect. Reduction of sulfur dioxide which had a reverse greenhouse effect is warming the oceans up more.

      “Carbon Brief analysis shows that the likely side-effect of the 2020 regulations to cut air pollution from shipping is to increase global temperatures by around 0.05C by 2050. This is equivalent to approximately two additional years of emissions.”

      https://www.carbonbrief.org/analysis-how-low-sulphur-shipping-rules-are-affecting-global-warming/#:~:text=Global emissions of sulphur dioxide,warming coming from greenhouse gases.

      So this may be our first example of the threats of NOT enacting terraforming for climate change will have.

      I believe by “interesting,” you mean “moist.” At least, for everyone above/below ±35° latitude.

      Also, I hope you enjoyed photosynthesis while it lasted because once the permafrosts at ±60° latitude thaw, we’re in for a tough time.

      They’ve been saying that literally since the 60’s?

      Aaaaaaaaaaaaaand they’re still wrong.
