Recent evidence points toward abrupt, irreversible sea level rise along the US coast

Red alerts signaling an AMOC slowdown

I am really really curious what in the USA will look like once this AMOC tipping point starts impacting it. The description of what happens to Northern Europe is horrific.

@b4cks4w @Ruthat

a climate journalist wrote a book about climate migration in the US. lots of different maps, but it sounds like agriculture is not going to be at the higher latitudes everywhere.

And I’m not sure where the AMOC fits in, how its slowing would affect the NE.

@b4cks4w @Ruthat

From the article, if the AMOC slows down (a climate change tipping point):

“ It will likely lead to a far colder Northern Europe that will periodically be swept by very hot winds from the south—meaning subject to a "crazy stormy climate" with "absolutely unprecedented weather extremes," in Rahmstorf's words. And, more generally, it will have profound implications for weather and agriculture around the globe, as hot areas get even hotter and rain patterns shift dramatically.”

When you nudge a stable system out of stability you get chaos, not a slightly different stability

@BrentSullivan @peeppeepcircus @Ruthat some questions about how stable this system is, but no doubt it's changing fast. Need another decade of data

I made the linked video 4 years ago and it discusses typing points and why climate predictions are coming true faster than forecast. I remember seeing reports then that the Gulf steam was slowing

:facepalm:
of course it’s not just us ignoring reality, it’s everyone, but still.

I had mentioned this book On the Move, it has a lot of maps of what our future will look like abrahm.com/

But I’m still trying to pinpoint exactly where agriculture will be possible on a map (say in 2050).

also, after some shocking megafires damaged the population in the Sierra Nevada mountain range in 2020-2021, I remember this excerpt from this pbs interview:

"Christy Brigham:
We really are seeing impacts of climate change that these parks & models did not predict until 2050 or 2080 at the earliest. And they are happening now."

My understanding is that weather becomes too chaotic for industrial scale agriculture anywhere.
At 4°, crop failures reach 60%
We're headed for 5° by the end of the century
The earth will be fine
Civilization wil crash and billions will die

Big brains and opposable thumbs are an evolutionary dead end unless we systematically change our entire economy in a mobilization reminiscent of WW2
