As the light disappears, billions of <a href="https://kolektiva.social/tags/zooplankton" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>zooplankton</span></a>, <a href="https://kolektiva.social/tags/crustaceans" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>crustaceans</span></a> and other marine organisms rise to the ocean surface to feed on microscopic <a href="https://kolektiva.social/tags/algae" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>algae</span></a>, returning to the depths at sunrise. The waste from this frenzy – Earth’s largest migration of creatures – sinks to the <a href="https://kolektiva.social/tags/ocean" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ocean</span></a> floor, removing millions of tonnes of <a href="https://kolektiva.social/tags/carbon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>carbon</span></a> from the atmosphere each year.</p><p>"This activity is one of thousands of natural processes that regulate the Earth’s climate. Together, the planet’s oceans, forests, soils and other natural carbon sinks absorb about half of all <a href="https://kolektiva.social/tags/HumanEmissions" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>HumanEmissions</span></a>.</p><p>"But as the Earth heats up, scientists are increasingly concerned that those crucial processes are breaking down.</p><p>"In 2023, the hottest year ever recorded, preliminary findings by an international team of researchers show the amount of carbon absorbed by land has temporarily collapsed. The final result was that <a href="https://kolektiva.social/tags/forest" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>forest</span></a>, plants and soil – as a net category – absorbed almost no carbon.</p><p>"There are warning signs at sea, too. <a href="https://kolektiva.social/tags/Greenland" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Greenland</span></a>’s Glaciers and <a href="https://kolektiva.social/tags/ArcticIceSheets" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ArcticIceSheets</span></a> are melting faster than expected, which is disrupting the <a href="https://kolektiva.social/tags/GulfStream" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>GulfStream</span></a> ocean current and slows the rate at which oceans absorb carbon. For the algae-eating zooplankton, melting sea ice is exposing them to more sunlight – a shift scientists say could keep them in the depths for longer, disrupting the vertical migration that stores carbon on the ocean floor."</p><p>Read more:<br><a href="https://www.theguardian.com/environment/2024/oct/14/nature-carbon-sink-collapse-global-heating-models-emissions-targets-evidence-aoe" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">theguardian.com/environment/20</span><span class="invisible">24/oct/14/nature-carbon-sink-collapse-global-heating-models-emissions-targets-evidence-aoe</span></a></p><p><a href="https://kolektiva.social/tags/ClimateChange" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ClimateChange</span></a> <a href="https://kolektiva.social/tags/ClimateCrisis" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ClimateCrisis</span></a> <a href="https://kolektiva.social/tags/ClimateCatastrophe" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ClimateCatastrophe</span></a> <a href="https://kolektiva.social/tags/Exctinction" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Exctinction</span></a> <a href="https://kolektiva.social/tags/GlobalWarming" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>GlobalWarming</span></a></p>
