Bart Verheggen<p>Hoe zit het nu met de <a href="https://sciencemastodon.com/tags/AMOC" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>AMOC</span></a>?</p><p>Een windgedreven component van de AMOC blijft sowieso bestaan. Een dergelijke sterk afgezwakte AMOC transporteert echter veel minder warmte, en wordt daarom meestal als een ineenstorting beschouwd.</p><p>Een nieuwe Britse studie noemt het echter geen ineenstorting, zelfs als er van het warmtetransport weinig overblijft. <br><a href="https://www.knmi.nl/over-het-knmi/nieuws/in-hoeverre-zal-de-golfstroom-verzwakken-onder-klimaatverandering-amoc-tipping-point" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">knmi.nl/over-het-knmi/nieuws/i</span><span class="invisible">n-hoeverre-zal-de-golfstroom-verzwakken-onder-klimaatverandering-amoc-tipping-point</span></a><br>Met de studie zelf is niks mis, maar met de framing wel.</p>
Mikko Tuomi<p>A major motor for the global <a href="https://scicomm.xyz/tags/climate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>climate</span></a> is beginning to falter: a massive system of <a href="https://scicomm.xyz/tags/ocean" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ocean</span></a> currents called the Atlantic Meridional Overturning Circulation (<a href="https://scicomm.xyz/tags/AMOC" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>AMOC</span></a>).</p><p>A weaker AMOC could produce long-term costs amounting to several trillion euros by the year 2100.</p><p>Weakening AMOC would further accelerate climate change because less CO₂ is transported from the surface ocean to the deep ocean.
