“A new study estimates that 2.3 C of warming is inevitable, but can be delayed for centuries if the world quickly stops emitting extra greenhouse gases from the burning of coal, oil and natural gas, the study’s authors say.”
The Paris goal is 1.5 C, and the carbon already in the air locks in 2.3 C. The targets were missed before the speeches ended. The only lever left is timing. Stop now and the bill comes due in centuries. Keep going and it comes due on our watch.
