Parts of Alaska’s mountainous Brooks Range were likely transported from Greenland and a stretch of the Canadian Arctic much farther to the east, according to a series of Dartmouth-led studies detailing over 300 million years of Arctic geologic history.

New research connects recent changes in the movement of North Atlantic right whales to decreased food availability and rising temperatures in Gulf of Maine’s deep waters. 

Once seen as spooky sci-fi, geoengineering to halt runaway climate change is now being looked at with growing urgency. 

A new study published today in Nature Climate Change finds coral reefs are under threat from ocean acidification.

Location matters for species struggling to survive under a changing climate.

As it does in the Arctic, the surface of the ocean around Antarctica freezes over in the winter and melts back each summer.

New model simulations of future Atlantic hurricane seasons suggest that higher greenhouse gas emissions will reduce vertical wind shear in an inconvenient place: along the U.S. East Coast.

Atmospheric researchers at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have now developed a climate model that can accurately depict the frequently observed winding course of the jet stream, a major air current over the Northern Hemisphere. 

Type “sea-level rise” in an internet search engine and almost all the resulting images will show flooded cities, with ample guidance on civic options for protecting urban infrastructure, from constructing seawalls to elevating roadways.

Rapid changes in terrain are taking place in Canada’s high Arctic polar deserts due to increases in summer air temperatures.
