Greenland’s inland ice is melting far faster than anyone thought
Inland melting of the Northeast Greenland Ice Stream is accelerating — and may contribute far more to sea level rise than earlier estimates suggested.

Heat waves appear more life-threatening than scientists once thought
This is bad news as a warming planet leads to growing numbers of excessive heat waves — and millions more people facing potentially deadly temperatures.

Uplifting Antarctic shores point to accelerating loss of glaciers
It appears the Pine Island and “Doomsday” Thwaites glaciers are losing ice — and shrinking faster — than at any time in the past 5,500 years.
