The most likely temperature rise by 2100 right now is 3.2°C.
There's only a 5% chance of greater than 5°C temperature rise. As well as a 5% chance of keeping warming under 2°C, and a 1% chance of keeping warming to 1.5°C.
The UN emissions gap report says we need to triple our current efforts to have a chance at keeping warming under 2°C. And increase efforts by 5x for 1.5°C.
Number of days above the deadly threshold for the RCP 8.5 scenario in 2100.
