Ariadne<p>"Meltwater is hydro-fracking Greenland's ice sheet, destabilizing its internal structure" - Glaciologist Alan Hubbard, in the field for 35 years, writes a superb, readable summary of what's really happening in <a href="https://climatejustice.social/tags/Greenland" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Greenland</span></a> and <a href="https://climatejustice.social/tags/Antarctica" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Antarctica</span></a>, and why it is far more frightening than what the <a href="https://climatejustice.social/tags/IPCC" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>IPCC</span></a> admits. Article also has excellent links.<br>...<br>"Current climate models lowball the risks - Along with other applied glaciologists, "structured expert judgment" and a few candid modelers, I contend that the current generation of ice sheet models used to inform the IPCC are not capturing the abrupt changes being observed in Greenland and Antarctica, or the risks that lie ahead."<br>...<br>"This is a tragedy in the making for the half a billion people who populate vulnerable coastal regions, since the Greenland and Antarctic ice sheets are effectively giant frozen freshwater reservoirs locking up in excess of 65 meters (over 200 feet) of equivalent global sea level rise. Since the 1990s their mass loss has been accelerating, becoming both the primary contributor to and the wild card in future sea level rise." <br>...<br>"...new research into the ice sheet's mechanics are challenging traditional thinking about what happens inside and under ice sheets, where observations are extremely challenging yet have stark implications. They suggest that Earth's remaining ice sheets in <a href="https://climatejustice.social/tags/Greenland" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Greenland</span></a> and <a href="https://climatejustice.social/tags/Antarctica" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Antarctica</span></a> are far more vulnerable to <a href="https://climatejustice.social/tags/climate" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>climate</span></a> warming than models predict, and that the ice sheets may be destabilizing from inside."</p><p><a href="https://phys.org/news/2023-06-meltwater-hydro-fracking-greenland-ice-sheet.html" rel="nofollow noopener" target="_blank"><span class="invisible">https://</span><span class="ellipsis">phys.org/news/2023-06-meltwate</span><span class="invisible">r-hydro-fracking-greenland-ice-sheet.html</span></a></p><p><a href="https://climatejustice.social/tags/ClimateCrisis" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ClimateCrisis</span></a> <a href="https://climatejustice.social/tags/GIS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>GIS</span></a> <a href="https://climatejustice.social/tags/GreenlandIceSheet" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>GreenlandIceSheet</span></a> <a href="https://climatejustice.social/tags/GlobalWarming" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>GlobalWarming</span></a> <a href="https://climatejustice.social/tags/Klimakrise" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Klimakrise</span></a> <a href="https://climatejustice.social/tags/Klima" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Klima</span></a> <a href="https://climatejustice.social/tags/Antarctica" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Antarctica</span></a> <a href="https://climatejustice.social/tags/IceSheets" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>IceSheets</span></a> <a href="https://climatejustice.social/tags/Glaciers" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Glaciers</span></a> <a href="https://climatejustice.social/tags/GlacialMelt" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>GlacialMelt</span></a> <a href="https://climatejustice.social/tags/ClimateModelling" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ClimateModelling</span></a> <a href="https://climatejustice.social/tags/ClimateModels" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ClimateModels</span></a></p>
