A seal pup found in Iceland about five months ago has now returned to its home turf in Greenland. The ringed seal pup was found behaving strangely in Njarðvík harbor.

Polar bears have been rummaging through science camps at the top of Greenland's ice sheet far inland, where they were never expected, and Polar bears are coming into communities more often these days, says Kristin Laidre, a marine biologist at the University of Washington’s Polar Science Center, and an authority on polar bear populations in Greenland. “It’s happening all over the Arctic, and it’s something that’s only going to be an increasing problem as we continue to lose sea ice,” she says.

Rain fell at the highest point on the Greenland ice sheet last week for the first time on record, another worrying sign of warming for the ice sheet already melting at an increasing rate, scientists said on Friday.

For three days this month, 7 billion tonnes of rain fell across Greenland — the largest amount since records began in 1950. It’s also the first time since then that rain, not snow, fell on Greenland’s highest peak.
