A “Hothouse Earth” climate will in the long term stabilize at a global average of 4-5°C higher than pre-industrial temperatures with sea level 10-60 m higher than today, the paper says.

The authors conclude it is now urgent to greatly accelerate the transition towards an emission-free world economy. Read more here
