PMeanwhile, Johan Rockström, the driving force behind the whole Planetary Boundaries framework, is now spelling it out as starkly as it needs to be:

“A 2.5°C global mean surface temperature rise is a disaster. It’s something that humanity has absolutely no evidence that we can cope with. There would be a 10-metre sea level rise. There would be a collapse of all the big biomes of planet Earth – the rainforest, many of the temperate forests, abrupt thawing of permafrost, and the complete collapse of marine biology. Over 1/3rd of the planet around the equatorial regions will be unhabitable because you will pass the threshold of health, which is around 30°C. It’s only some parts of the Sahara Desert today that has that kind of average temperature.”

    The last sentence does the article a disservice by qualifying the warnings with “before it’s too late”. That implies we still have time, that we can fix it if we just all work together. Pro-tip: it’s too late.

    I think I’d feel better if the discussion turned more towards “how do we cope” vs prevention.

      That sea level rise is most likely for next century, so you can still enjoy it while you cope…

      Joke aside, maybe the 1 billion people will be the realistic scenario, and we’ll just live north.
