Ja, 100-150 years from tipping to full shutdown. Then 600-1000 years for overturning to resume and get back to normal.
At least, that is how it used to be in #paleoclimate when shutdowns only occured during and after ice ages. Not in a warm interglacial in full swing.
I can imagine, the #AMOC collapse phase is much shorter this time, and resumption takes far longer

And it's a high emission pathway we're on.

New climate modeling shows the Harappan world shifted not through sudden collapse but centuries of recurring drought. A story of resilience, adaptation, and the limits of river civilizations. #Archaeology #Paleoclimate #IndusValley #Anthropology https://www.anthropology.net/p/when-rivers-faded-climate-whiplash
When Rivers Faded: Climate Whiplash and the Long Slow Transformation of the Harappan World

New paleoclimate modeling suggests that centuries of shifting drought cycles reshaped one of humanity's earliest urban experiments.

I have the first paper in my 2026 folder! Altyeb et al present a compilation of Last Interglacial (MIS 5e) sea level proxies along the Egyptian Coast of the Red Sea. It looks like the northern part of the coast is affected by tectonics.

What if, when we stroll into California and feel at home, we're reminded not of any paradise of today, but rather Africa in the last ice age? The science, shockingly, checks out...

Tang et al present new sea level index points for the Bohai Sea, providing a much better constrained mid-late Holocene sea level reconstruction than was available before. There is strong evidence that relative sea level was 2.2-3.5 m higher than present in the mid-Holocene.

Langford et al report on paleo sea level during MIS 7 and 5e for Fenland in eastern England. In both cases, paleo sea level was higher than present in Fenland. I think this adds to the growing evidence that global sea level in MIS 7 did go above present level.

🔎 130,000 years of climate history in 2,700 meters of core samples – that's the Eifel Laminated Sediment Archive (ELSA) at #MainzUniversity. The unique geoarchive has been built and expanded by geoscientist Professor Frank Sirocko over the last 25 years. Even though he will soon be taking his well-earned retirement, drilling projects in the Eifel will continue ...

Coral fossils reveal 600,000 years of hidden climate records

A breakthrough in nuclear imaging is unlocking coral fossils to reveal 600,000 years of reef and climate evolution.

Intriguing 1mio year old skull from China, DNA and bones of Homo longi, a sister species at similar levels of development to Neanderthals and Homo sapiens.

That's 700thsd years earlier than taught and thought.

I say, look for them in mid latitudes in locations not likely to have been in use by ice age populations. If cave dwellers found a stash of old bones in their new home they likely got rid of them.
And besides: earlier than 1mio years ago, caves weren't needed as much for shelter bc it didn't get so cold in Europe's latitudes and further East.

I think, Africa was too hot and species development was interrupted or took place somewhere else entirely.

Just look at maps of climate projections and the tropical death zones.

Million-year-old skull rewrites human evolution, say scientists

New analysis suggests our species began to emerge at least half a million years earlier than we thought
