Holger Behrens<p>The stability of the AMOC is crucial for maintaining a balanced climate, especially for countries surrounding the Atlantic Ocean. A significant slowdown or collapse of the AMOC could lead to abrupt and potentially irreversible changes in climate.

This wind pulls up water from the deep Southern Ocean and is thus also part of the AMOC, a part projected to speed up, not slow down. Yay. <br>But.<br>Pulling up deep water faster also pulls up the old carbon faster which was transported there by the AMOC. <br>So...uhm, does this increased wind-driven carbon upwelling intensify the effect of the ever-reduced carbon removal by the slowing AMOC? <br>I bet, this would be visible in <a href="https://climatejustice.social/tags/paleoclimate" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>paleoclimate</span></a> data around the Younger Dryas. Eg, pairing the Greenland annual temperature time series and annual Antarctic CO2 record. <br>If correct then I'd expect: just before the AMOC collapse, when Greenland still heats up, CO2 growth should increase. And when AMOC slows down, when Greenland starts cooling, the annual growth in CO2 should further intensify. <br>Unless... hm. The re-cooling also buries a lot of soil and plants under new ice in Scandinavia and Canada. Could be, this process balances the otherwise expected growth increase.Hm.</p><p>Going to look at it tomorrow. Am again completely in awe that we do have annually resolved Greenland temperature and Antarctic CO2 levels all the way back to the previous interglacial!!</p>

Michl<p>TIL der nordatlantische Umwälzstrom AMOC schwächt sich ab. Das sorgt für Veränderungen im Niederschlag, steigenden Meeresspiegeln, usw. Zudem können die Meere damit weniger CO2 "verschlucken". Das wiegt den kühlenden Effekt der Abschwächung komplett auf und sorgt so für weitere Erwärmung <a href="https://www.uni-hamburg.de/newsroom/forschung/2025/0225-amoc.html" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">uni-hamburg.de/newsroom/forsch</span><span class="invisible">ung/2025/0225-amoc.html</span></a> <a href="https://sueden.social/tags/amoc" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>amoc</span></a> <a href="https://sueden.social/tags/klimawandel" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>klimawandel</span></a> <a href="https://sueden.social/tags/CO2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CO2</span></a></p>
