In Greenland, these warm rivers in the sky also play a role in melting the ice sheet. Amid rising temperatures, Greenland has lost more ice mass than it gained for 25 years in a row.

Quakes recorded for the first time inside Greenland's biggest frozen river, the Northeast Greenland Ice Stream, suggest this river and others switch between moving jerkily and flowing like honey.

Greenland’s ice sheet is the second-largest ice cap on Earth, and because of the planet’s rising temperatures, it’s melting.Human-induced climate change is intensifying atmospheric rivers ...

T ypically, when scientists imagine going inside the deep bundles of ice in Earth’s polar regions, they think of ice flowing ...

Far below the frozen cover of the Greenland ice sheet sprawls miles of bedrock — and extending through that bedrock for close to 1,000 miles is a valley that may contain a subterranean river ...

New rivers of meltwater are appearing by the thousands on Greenland's ice sheet and dumping gigatonnes of water into the ocean that could boost sea levels faster than expected, a new study suggests.

A secret network of rivers was recently discovered beneath the Jakobsvahn Isbrae glacier in Greenland. The primeval river network is mostly dry, but water may still flow through the riverbeds ...

This river is one of a network of thousands at the front line of climate change. On the Greenland Ice Sheet — The midnight sun still gleamed at 1 a.m. across the brilliant expanse of the ...

This region in Greenland could be exporting up to 42 tonnes of mercury every year – around 10 per cent of the estimated global export of mercury from rivers into the oceans.

Melting ice in Greenland has swelled the island's rivers with water. A NASA satellite snapped a photo of meltwater overflowing the banks of the Watson River near Kangerlussuaq, a key air ...

More than 9,000 acres in the Hudson River Valley and as many as 3,600 households could be inundated by 2100 just at high tide, if global sea levels rise by as much as 6 feet, according to a recent ...
