jbz<p>🛰️ Unprecedented Starlink Reentries </p><p>｢ What we’re observing is a giant uncontrolled experiment in atmospheric chemistry. The demise of just one Gen1 Starlink satellite produces about 30 kilograms (66 pounds) of aluminum oxide, a compound that eats away at the ozone layer. A new study finds these oxides have increased 8-fold between 2016 and 2022, and the recent surge is increasing the pollution even more ｣</p><p><a href="http://spaceweatherarchive.com/2025/02/19/unprecedented-starlink-reentries/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">http://</span><span class="ellipsis">spaceweatherarchive.com/2025/0</span><span class="invisible">2/19/unprecedented-starlink-reentries/</span></a></p><p><a href="https://indieweb.social/tags/starlink" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>starlink</span></a> <a href="https://indieweb.social/tags/climatechange" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>climatechange</span></a> <a href="https://indieweb.social/tags/ozonelayer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ozonelayer</span></a> <a href="https://indieweb.social/tags/musk" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>musk</span></a></p>

clacke: exhausted pixie dream boy 🇸🇪🇭🇰💙💛<p>There's a natural variation in ozone in the atmosphere, but CFCs and other substances were reducing ozone levels and expanding the seasonal ozone holes over the poles. The problem was real and it was getting worse, because CFCs were produced for a reason: It was really useful and cost-effective stuff.</p><p>Banning ozone-depleting substances for use as coolants, fire supressants, aerosol propellants and other applications was very successful, and after four decades we are now more than halfway to recovering to natural ozone levels.</p><p>A few years ago there was briefly some illegal production of CFCs, which halted the recovery, but it was tracked down and halted, and we are back on track.</p><p><a href="https://www.nasa.gov/missions/aura/nasa-study-first-direct-proof-of-ozone-hole-recovery-due-to-chemicals-ban/" rel="nofollow noopener noreferrer" target="_blank">nasa.gov/missions/aura/nasa-st…</a></p><p><a href="https://www.bbc.com/news/science-environment-56014092" rel="nofollow noopener noreferrer" target="_blank">bbc.com/news/science-environme…</a></p><p><a href="https://en.wikipedia.org/wiki/Ozone_depletion" rel="nofollow noopener noreferrer" target="_blank">en.wikipedia.org/wiki/Ozone_de…</a></p><p><a href="https://libranet.de/search?tag=OzoneLayer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OzoneLayer</span></a> <a href="https://libranet.de/search?tag=OzoneDepletion" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OzoneDepletion</span></a><br><a href="https://libranet.de/search?tag=OzoneDepletingSubstances" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OzoneDepletingSubstances</span></a> <a href="https://libranet.de/search?tag=ODSes" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ODSes</span></a><br><a href="https://libranet.de/search?tag=chlorofluorocarbons" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>chlorofluorocarbons</span></a> <a href="https://libranet.de/search?tag=CFCs" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>CFCs</span></a></p>

jbz<p>🛰️ Satellite 'megaconstellations' may jeopardize recovery of ozone hole | Phys</p><p>｢ When old satellites fall into Earth's atmosphere and burn up, they leave behind tiny particles of aluminum oxide, which eat away at Earth's protective ozone layer.
