Scientists are “very worried” that the Greenland ice sheet might start to melt “faster and faster”, a leading scientist has said, as reported by The Independent.
The problem is that the warmer weather is allowing more dark algae to grow on the ice. Because ice is white, it reflects much of the sun’s energy, but dark algae absorb the heat, increasing the rate of melting.
The Greenland ice sheet is up to 3km thick and would raise sea levels by seven metres if it all melted into the sea. The current rate of melting is adding about 1mm a year to the global average sea level.
