Still haven't gotten around comprehending how to convert a lat-lon grid with ice thickness to a correct regional sum of freshwater amount in Gt.
But something else keeps popping up in my head now.
Peltier's ice model / reconstruction (dunno which it is) doesn't include sea ice at all https://www.atmosp.physics.utoronto.ca/~peltier/data.php
Tarasov's GLAC1D model does. https://doi.org/10.5281/zenodo.10159104
At least the melted parts of sea ice is included. But not the ever-lasting part.That ever-lasting part is melting today, and has been melting for a long while now. But it didn't melt during past AMOC hickups. What melted back then was ice that covered Scotland with a whopping 400m ice wall. And higher ice mountains still melted in other regions. But not sea ice in the Arctic ocean.
...hm. What I really want to know is how the amount of freshwater influx back then
compares to the amount today, and how today's very little left-over ice would be capable of stopping AMOC.We'll be having a blue Arctic ocean before 2030, says a new study https://www.ft.com/content/63fbcf2b-9acc-4ccb-ac12-9f3b78e85b68

Wouldn't it be cool to know by then how much ice in kilos or Gt melted ? And how that amount compares to the amount before previous AMOC shutdowns during the LGM and deglaciasation?

🚨 UN weather agency issues ‘red alert’ on #ClimateChange after record heat, ice-melt increases in 2023
"Earth’s issuing a distress call. The latest State of the Global Climate report shows a planet on the brink. #FossilFuel pollution is sending #ClimateChaos off the charts." - U.N. Secretary-General Antonio Guterres.
By JAMEY KEATEN and SETH BORENSTEIN
Updated 6:11 PM EDT, March 19, 2024GENEVA (AP) — "The U.N. weather agency is sounding a 'red alert' about global warming, citing record-smashing increases last year in #GreenhouseGases, land and water temperatures and melting of glaciers and sea ice, and is warning that the world’s efforts to reverse the trend have been inadequate.
"The World Meteorological Organization said there is a 'high probability' that 2024 will be another record-hot year.
"The Geneva-based agency, in a 'State of the Global Climate' report released Tuesday, ratcheted up concerns that a much-vaunted climate goal is increasingly in jeopardy: That the world can unite to limit planetary warming to no more than 1.5 degrees Celsius (2.7 degrees Fahrenheit) from #preindustrial levels."
