‘Millions in coastal communities’ threatened by algae growth on Greenland Ice Sheet

Increased melting of the Greenland Ice Sheet has the potential to threaten millions of people in coastal cities worldwide, according to scientists studying the effect of algae on melting in the region.

The group of UK scientists say they are “very worried” as warmer conditions in the area are enabling algae to grow on the ice. The algae, which turns the ice green, brown and even black, darkens the surface and makes it more susceptible to the sun’s energy, increasing melting.

Such dark patches reflect between 1 and 35 percent meaning it melts much quicker than white ice, according to BBC News. read more
