Warming of Deepest Oceans within Arctic Bad Signal of Reduced Sea Ice and Slowing AMOC
This fascinating study looks at warming at the ocean floor in the Arctic regions and in the North Atlantic Ocean south of Greenland.
Of course, a slowing AMOC means less cold salty water descends to the ocean floor from the surface, thus, without this cold water source we get lots of warming deep down.
It is awesome that science continues around the world, even though it is rapidly dying in the good ole' USA...

Deep Arctic Ocean warming enhanced by heat transferred from deep Atlantic
Authors: Ruizhe, Xianyao, Hanwen Bi, Xiaoyu Wang, Longjiang Mu
Abstract
Observations since the 1990s reveal widespread warming in the deep and bottom Arctic Ocean. It is historically attributed to geothermal heating, whereas the impacts of global and Arctic climate change on the deep and bot-tom Arctic Ocean warming remain unresolved. Our study demonstrates that during the recent decades, the Arctic Ocean deep water is warming at 0.020°C/decade in the Eurasian Basin between 2000 and 2600 m, exceeding what can be explained by geothermal heating. We find that the rapid warming in the deep Greenland Basin diminishes its cooling effect on the deep Eurasian Basin via the Fram Strait, leading to the warming in the deep Eurasian Ba-sin. Meanwhile, the Lomonosov Ridge blocks this warming signal from reaching the deep Amerasian Basin, maintaining its relative slow warming rate of 0.003°C/decade. Our findings indicate that the deep Greenland Basin warming has already exerted obvious impacts on the deep Arctic Ocean.
