The tougher nut to crack will be Siberia.

Permafrost Thaw in Siberia Creates a Ticking ‘Methane Bomb’ of Greenhouse Gases, Scientists Warn
In 2020, temperatures in the region rose nearly 11 degrees Fahrenheit above normal, causing the limestone to release ancient methane deposits

In recent years, climate scientists have warned thawing permafrost in Siberia may be a “
methane time bomb” detonating slowly. Now, a
peer-reviewed study using satellite imagery and a
review by an international organization are warning that warming temperatures in the far northern reaches of Russia are releasing massive measures of methane—a potent greenhouse gas with considerably more warming power than carbon dioxide.
“It’s not good news if it’s right,” Robert Max Holmes, a senior scientist at the
Woodwell Climate Research Center, who was not involved in either report, tells Steve Mufson of the
Washington Post. “Nobody wants to see more potentially nasty feedbacks and this is potentially one.”
Published in the
Proceedings of the National Academy of Sciences journal, the study of satellite photos of a previously unexplored site in Siberia detected large amounts of methane being released from exposed limestone. A heat wave in 2020 was responsible for the emissions along two large strips of rock formations in the
Yenisey-Khatanga Basin, located several hundred miles north of the Arctic Circle.
Lead author Nikolaus Froitzheim, a geoscientist at the
University of Bonn in Germany, is concerned about his study’s findings. Interpreting this data correctly “may make the difference between catastrophe and apocalypse” as the climate crisis worsens, he tells Tara Yarlagadda of
Inverse.
