You wouldn’t generally think of ocean temperatures in the range of 40 to 50 degrees Fahrenheit (5 to 10 degrees Celsius) as hot. But to the great sea-fronting glaciers of Greenland it may as well be boiling.
Greenland Ice Sheet in Hot Water
All it takes is 32 degree F (0 C) water to begin melting the ice. And for each 1 degree increase above that margin, melt rates will dramatically ramp higher. Though a typical summer will push ice to melt at the Greenland seafront ice edge, this year, especially near Baffin Bay, the melt pressure has been extraordinary.
Ever since late June, 40-50 degree F sea surface temperatures have dominated the ice edge zone. For most regions that’s temperatures in the range of 4-11 degrees Fahrenheit (2-6 C) above average. The kind of heat that really risks a rapid melt along the ice margin. Sourced through Scoop.it from: robertscribbler.com
Melting ice is changing the oceans in ways harmful to all life on Earth.
