A new study shows just how quickly the world’s cryosphere is shrinking
More than 102,000 square kilometers of frozen areas were lost in the Northern Hemisphere from 1979 to 2016.
The world’s frozen areas lost an average of about 87,000 square kilometers (33,000 square miles) a year from 1979 to 2016, and the period of annual freeze has shrunk by more than a week over the nearly four-decade period, according to a new study published in the journal Earth’s Future.
