Prominent climate scientists are pushing back against the view, promoted by media coverage of recent science reports as well as climate advocates, that we have only 12 years to act on global warming or face an existential threat to humanity.

Why it matters: This do-or-die framing has found a powerful advocate in Democratic freshman Rep. Alexandria Ocasio-Cortez, who said on Monday that millennials understand that we only have 12 years or "the world is going to end." She is pushing a broad policy proposal to address climate change, known as the Green New Deal.

Why it matters: The polling may indicate that extreme weather events — coupled with a series of grim scientific findings — over the past year are starting to change peoples' minds about climate change, which could have significant implications for any significant climate legislation passing Congress.
