"The new study adds significantly to the rising concern about an AMOC collapse in the not-too-distant future," said one scientist. "We will ignore this at our peril."
It might be my naive reading, but it seems that flooding the ocean with 4-5% of the gulf stream flow with fresh water from glacier melt (I think that’s a lot) will cause a shut down in the year 3700 or so.
I’m curious where you got the year 3700 from. What I read is that they call into question current early warning signals, while offering a more robust indicator instead. This provides a new timeline of slowdown, but there is not enough data to tell us where we are on that timeline. Current estimates of 2025-2100 were not invalidated, while we were confirmed to be on route to the tipping point at present.
Graph A (https://www.science.org/doi/10.1126/sciadv.adk1189) just has model year and not the actual year in the common era.
I just assumed all of it was extrapolation from today, which shows a cliff in about 1700 years, so give or take 3700CE.
