Batagaika "Hellmouth" In Siberia Expanding Faster Than Ever @ 40-50 Feet Per Year

[hatrack]

Record-setting summer temperatures across Siberia are opening up the Batagaika megaslump, which locals call the “gateway to the underworld,” at an unprecedented pace, scientists say.

The Batagaika crater in the eastern Siberian republic of Sakha appeared in the 1960s after forest in the area was cleared, causing the land to sink. Currently the world’s largest megaslump at about 1 kilometer in length and 100 meters deep, it continues to grow in size and depth as climate change melts the fast-heating region’s permafrost layer. Batagaika’s diameter is now advancing outward at roughly 12 to 14 meters per year, Science magazine cited University of Potsdam permafrost researcher Frank Guenther as saying last week. Before 2016, it had advanced at 10 meters per year he said.

As the crater expands, scientists and archaeologists are discovering well-preserved remains of animals and plants that have been extinct since the Ice Age. The site also offers insight into 200,000 years of climate data.

Kseniia Ashastina, a paleobotanist at the Max Planck Institute for the Science of Human History, told Science magazine that local indigenous groups fear the crater, saying “it’s eating their land, swallowing up the trees and their sacred places.”

The news comes as Russia’s Arctic and Siberian regions, already warming at a faster rate than the rest of the world, face a historic summer heat wave accompanied by wildfires, fuel spills, crop failures and more.
