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.

The ROSETTA-Ice project, a three-year, multi-institutional data collection survey of Antarctic ice, has assembled an unprecedented view of the Ross Ice Shelf, its structure and how it has been changing over time.

Researchers at the University of Southampton have forecast a worldwide move towards smaller birds and mammals over the next 100 years.

Concentrations of antibiotics found in some of the world’s rivers exceed ‘safe’ levels by up to 300 times, the first ever global study has discovered.

At the end of the summer, a research expedition to the remote Ryder Glacier in northwestern Greenland will be carried out using the Swedish icebreaker Oden. 

“For every 100 beef burgers we eat, that’s around 750 pounds of greenhouse gas emissions, and that’s a conservative estimate,” says Abdulrahman Hassaballah, a PhD candidate in the Department of Civil, Structural and Environmental Engineering.
