GEOGRAPHY IN THE NEWS:
There is a new geographic feature popping up in the permafrost of northern Siberia: exploding craters, in some cases well over 150 feet deep. Scientists are working to riddle out what is causing these enormous holes, which started developing in 2013 and have been known to explode with enough force to eject rocks and ice more than 300 feet. (Hint: methane may be playing a role.) www.bbc.com/future/article/20201130-climate-change-the-mystery-of-siberias-explosive-craters
