On track for catastrophic global warming

Grist Article “IPCC your point

Beacon article by Zoya Fierstien“It’s Monday, October 8, and we’re on track for catastrophic global warming. Here’s what we need to do to slow it.”

Online  —  “Hundreds of the world’s top scientists compiled thousands of research documents to assess our progress on limiting global emissions.

“Today, the Intergovernmental Panel on Climate Change handed down its verdict: If we don’t fundamentally shift the path we’re on, we’ll hit 3.4 degrees C of warming by the end of the century and civilization will suffer.

“A lot.”

“The planet has already warmed 1 degree. And the effects of that warming have become glaringly evident in the past few years — larger, wetter hurricanes; ferocious wildfires; drought; the list goes on.

“The Paris Agreement sought to limit warming to below 2 degrees C. This report shows what it would take to keep it to a much safer 1.5 degrees. And bad news: We’re going to hit 1.5 degrees in just 12 years.

“It’s hard to sugarcoat this one. At this rate, we’re essentially doubling the pace of warming outlined in the Paris Agreement. That means mass flora and fauna extinctions, even more extreme weather, and probably a lot of death.

“But the report also outlines a roadmap for how we can pull off the kind of transformational shift necessary to keep us under 1.5 degrees C. Whether world governments actually take these recommendations into account is another story (one we’ve written about a lot).

“Here’s the deal:

  • The globe must invest $2.4 trillion in renewables every single year from now until 2035 — seven times more than we invested in 2017.
  • Eliminate coal by 2050. Yeah, like, all of it.
  • Future investments in natural gas should be switched to renewables instead. Even when done right, natural gas still pushes us toward a bleak future.

“And, as my colleague Eric Holthaus wrote today, the IPCC gives cause for courage here: “There is no time left to wait for the perfect solution or the perfect moment to enact a grand, top-down strategy.”

“All options need to be exercised,” said Scottish climate scientist Jim Skea, one of the report’s lead authors, at a press conference. “We can make choices about how much of each option we use … but the idea you can leave anything out is impossible.”

Is all hope lost? Nope. We’re the masters of our own destiny. If we give up, we’re even more screwed. Everybody needs to get to work.”
