A new study was released in @ScienceMagazine today: if we don't cut emissions and stay below 1.5°C, we'll witness 4 critical tipping points:
1) collapse of the Greenland and 2) West Antarctic ice sheets,
3) loss of coral reefs
4) thawing of permafrost

Published in @ScienceMagazine, the study is a wake up call on #climate, if there ever was one. Here's the conclusion:
"Our assessment provides strong scientific evidence for urgent action to mitigate climate change..."

"We show that even the Paris Agreement goal of limiting warming to well below 2°C and preferably 1.5°C is not safe as 1.5°C and above risks crossing multiple tipping points. Crossing these CTPs can generate positive feedbacks that increase the likelihood of crossing other CTPs."
"Currently the world is heading toward ~2-3°C of global warming; at best, if all net-zero pledges and NDCs are implemented it could reach just below 2°C."
At 2°C we have no corals, no major ice sheets, and permafrost melt which releases CH4 and brings more warming.

This work isn't a surprise for many of us in #climate, but it is a healthy reminder of the urgency of the issue, the immediacy of harm, and the extent of damage that we can expect.
If I could roll my sleeves any further to work HARDER on this problem, I sure as fuck would. You?
