Global warming appears to have shifted into a faster gear. After removing the effects of El Niño, volcanic eruptions, and solar cycles, researchers found that the planet has warmed at roughly 0.35°C per decade over the past ten years, compared with just under 0.2°C per decade from 1970 to 2015. The acceleration, which becomes visible around 2013 to 2015, appeared across five major global temperature datasets with more than 98% statistical certainty.

    ‘Sharp acceleration’ meaning 75% faster warming in the last decade compared to the 40 years previous, and blowing past the 1.5° target in 3-4 years. No speculation was given, but I think it’s likely we’re seeing the limits of oceanic absorption of co2 and heat. The ocean’s latent heat capacity has flattened the curve for more than a century, and it’s very hard to predict when that will run out, but sea surface temperatures spiking all over have been good evidence that we have passed a major tipping point in the last few years.

      I’ve read that the models used to predict the rate of change were too optimistic or an assumption about them was too conservative and thus not very realistic. Now we have data showing the models under-predicted the rate of change, so one argument is that we were already on this path since decades ago, we just didn’t model it right.

      In any case, we’re all fucked so who gives a shit anyway no?

      Is there a name for when we know what the right thing to do is but we keep not doing it?

          No way in hell we’re facing an extinction event. Unimaginable human suffering, probably, but humanity will persist.

            Isolated pockets in relatively protected areas. Global society won’t survive it. Most of the places we grow food won’t be able to grow food, that’s already accelerating. Ocean acidification kills that food source. Blue ocean event accelerates runaway heating leading to massive hurricane force continental storms. Amoc shuts down and Europe ices over. Humanity may persist but civilization won’t.

              Vast current areas become arid but vast areas in Siberia and Canada become arable. Very bad but not extinction for humans. Likely extinction for many species though.

                that’s also not true! vast current areas become arid tropical. see the tropical rainforest. it’s the hottest and simultaneously wettest regions on earth.
