Enormous Impact Crater Spotted in Greenland Under Glacial Ice
Ice-penetrating radar revealed a 31-kilometer impact crater—one of the world’s largest—in northwestern Greenland that might have been formed fewer than 20,000 years ago.

Black Carbon Not the Primary Cause of Historic Glacial Retreat
Ice cores and glacial records reveal that European glaciers retreated before the rise of industrialization in the 1870s, suggesting that soot deposition did not primarily drive the shift.
