Dimensions vary by source, but the site covers around 192 acres (78 hectares) and stretches two thirds of a mile (one kilometer) in length. Logged of trees in the 1960s, its walls reach a depth of around 180 feet (55 meters) and expose 650,000 years of geologic history. Since first spotted in the 1960s by surveillance satellites, the crater has grownfrom an insignificant gully to a massive depression at an accelerating rate. According to Sarah Cadieux, Sr. Lecturer and Associate Director of Environmental Science of Rensselaer Polytechnic Institute, the crater area increased by almost three times from 1991 to 2018.The Batagaika crater isn’t a crater at all, it’s a <a href="https://c.im/tags/retrogressive" class="mention hashtag" rel="nofollow noopener" target="_blank">#retrogressive</a> <a href="https://c.im/tags/thaw" class="mention hashtag" rel="nofollow noopener" target="_blank">#thaw</a> <a href="https://c.im/tags/slump" class="mention hashtag" rel="nofollow noopener" target="_blank">#slump</a>, a type of terrain called <a href="https://c.im/tags/thermokarst" class="mention hashtag" rel="nofollow noopener" target="_blank">#thermokarst</a> that occurs in areas underlain by permafrost.

This is not an isolated case, but rather a rapidly growing problem in the Arctic as 💥it warms three to four times the rate of the rest of the planet since 1979.Called Arctic or polar <a href="https://c.im/tags/amplification" class="mention hashtag" rel="nofollow noopener" target="_blank">#amplification</a>, this phenomenon is a well established fact measured by instruments, confirmed in climate computer models, and reinforced by paleoclimate records. Powerful anecdotal evidence occurred in the scorching heatwave of 2020 that saw the Russian town of Verkhoyansk which lies north of the Arctic Circle hit a stunning 38° C (100.4° F) on June 20. 2020 also saw overall temperatures in the Siberian basin rise to nearly 11° F above normal, shocking scientists and releasing <a href="https://c.im/tags/ancient" class="mention hashtag" rel="nofollow noopener" target="_blank">#ancient</a> <a href="https://c.im/tags/methane" class="mention hashtag" rel="nofollow noopener" target="_blank">#methane</a> not from ancient organic material, but from <a href="https://c.im/tags/limestone" class="mention hashtag" rel="nofollow noopener" target="_blank">#limestone</a>.
