anlomedad<p>Due to acid rain, countries lowered SO2 emissions from industry and power plants. But SO2 is also a coolant via cloud-seeding aerosols. See Glen Peters' tweet: globally -0.5°C from 2010-2019. A very short lifetime of mere days means, SO2 molecules cool only locally, while methane and CO2 heat all.</p><p>SO2 is emitted by burning coal and ship fuel, & in <a href="https://climatejustice.social/tags/volcanism" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>volcanism</span></a>. <br>The other major coolant NOx, also short-lived with regional not global direct forcing, is emitted by burning fossil fuels eg in cars, and lightening storms & biomass burning. <br>So when our emissions drop, local heating goes up: " <a href="https://climatejustice.social/tags/TerminationShock" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>TerminationShock</span></a>".</p><p>When I say "local heating goes up", I should add that via wind and land-atmosphere and ocean-atmosphere interaction, this local heating also has global repercussions. Eg., wind drives the warm-er air parcel across the globe. So a warmer China and Japan who ditched SO2 and NOx, also heat the <a href="https://climatejustice.social/tags/Pacific" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Pacific</span></a>.</p><p>Lowering SO2 and NOx while N2O (fertilizer), CH4 and CO2 emissions still rise is rather stupid.<br><a href="https://climatejustice.social/tags/climate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>climate</span></a> <a href="https://climatejustice.social/tags/climateChange" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>climateChange</span></a> <a href="https://climatejustice.social/tags/methane" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>methane</span></a> <a href="https://climatejustice.social/tags/SO2" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SO2</span></a> <a href="https://climatejustice.social/tags/NOx" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NOx</span></a> <a href="https://climatejustice.social/tags/atmosphere" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>atmosphere</span></a> <a href="https://climatejustice.social/tags/ocean" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ocean</span></a></p>
