UNEP says a 1.5°C overshoot is now unavoidable

UNEP’s annual emissions report says the world can no longer avoid exceeding 1.5°C without or with only limited overshoot. It calls for steep emissions cuts to limit the overshoot and return to 1.5°C by 2100, though that outcome is estimated to have about a 50% chance and depends on large-scale carbon removal.

UN says world can no longer avoid overshooting 1.5°C climate goal

The UN Environment Programme said Wednesday that sharp emissions cuts could still limit warming and bring temperatures back to 1.5°C by 2100. Current policies instead point to a 2.8°C rise by then.
