Greenland’s Ice Mystery Solved!
Reason for Greenland’s ice bed softening.
The secret of a developing “dim zone” on Greenland’s softening ice sheet has been tackled.
Analysts have discovered that phosphorus-rich residue blown across the ice might be the way into the wonder.
Greenland’s ice sheet is the second biggest on the planet. It covers around 656,000 square miles (1.71 million square kilometers), a region multiple times the size of Texas, as indicated by the National Snow and Ice Data Center (NSIDC). Be that as it may, the ice sheet is currently in a condition of perpetual retreat and is losing 500 gigatons (500 billion tons) of ice each year, Live Science recently announced.
That is the reason the dull zone is so troubling. Throughout the mid-year months, part of the western segment of the ice sheet abandons splendid white to inky dark as green growth blossom across the surface. Since 2000, these sprouts have gotten greater, making the dim zone extend, as per an assertion by the specialists.
The hazier shade of the ice lessens its albedo — the measure of daylight it reflects back to space — and causes the ice sheet to retain more warmth. In any case, up to this point, what triggers these algal blossoms has stayed a secret.
