World losing almost 20,000 square miles of sea ice each year

Environmental News Network - Sea ice increases in Antarctica do not make up for the accelerated Arctic sea ice loss of the last three decades, according to the stark findings of a new NASA study.

As a whole, the planet has been shedding sea ice at an average annual rate of 13,500 square miles (35,000 square kilometers) since 1979, the equivalent of losing an area of sea ice larger than the state of Maryland every year.

However, the rate of sea ice loss has recently doubled to now reach an alarming rate of nearly 20,000 square miles.
