- The world's 1.5°C climate goal is slipping out of reach - so now what? Scientists say it is still theoretically possible to limit global warming to 1.5°C, but realistically that now seems practically impossible. Should we admit our failure and double down on holding warming below 2°C? https://www.newscientist.com/article/2323175-the-worlds-1-5c-climate-goal-is-slipping-out-of-reach-so-now-what/#Echobox=1654735884 267 comments futurology

- When warming is limited to 1.5°C as compared with 2°C, numbers of species projected to lose >50% of their range are reduced by ~66% in insects and by ~50% in plants and vertebrates.

- Previously it was calculated that 3.5°C of warming by 2100 might be an economically desirable outcome; however, an update to the DICE model now shows that limiting global warming to below 2°C strikes an economically optimal balance between future climate damages and today’s climate mitigation costs. https://idw-online.de/de/news750985 9 comments science
