North Pacific winter storm tracks shifting poleward much faster than predicted
Alaska’s glaciers are melting at an accelerating pace, losing roughly 60 billion tons of ice each year. About 4,000 kilometers to the south, in California and Nevada, records for heat and dryness are being shattered, creating favorable conditions…

Sentinel-1's decade of essential data over shifting ice sheets
The extent and speed of ice moving off the ice sheets of Greenland and Antarctica into the sea—an important dynamic for climate and sea-rise modeling—has been captured over a 10-year period by satellites from the Copernicus Sentinel-1 mission.

Greenland Ice Cap Vanished 7,000 Years Ago, and It Could Happen Again
Analysis of core samples extracted from beneath an ice sheet indicates that the region is extremely responsive to the temperatures characteristic of today’s interglacial period. Researchers involved in GreenDrill, a project jointly led by the…

Small-scale rainforest clearing drives majority of carbon loss, study finds
Think of the destruction of Earth’s rainforests and a familiar image may come to mind: fires or chainsaws tearing through enormous swaths of the Amazon, releasing masses of planet-warming carbon dioxide.

How is drought in New England affecting water levels and the environment?
Recent reports of wells drying up in New Hampshire reflect a pattern we’re increasingly seeing across New England: extended dry periods and below-normal precipitation are stressing shallow groundwater systems that many homeowners depend on.
