“We May Have Just Bought Ourselves An Extra Decade To Avoid Catastrophic Climate Change”
The world appears to have bought itself a little time in the fight to avoid climate catastrophe, according to a new analysis.
Virtually every major country has made pledges to limit or reduce carbon pollution in advance of the Paris climate talks this December. These pledges generally end in 2025 or 2030, and so they only matter if the world keeps ratcheting down its greenhouse gas emissions in future agreements until we get near zero by century’s end. Otherwise we will blow past the 2°C line of defense against very dangerous-to-catastrophic global warming, and hit 3.6°C warming by 2100.
