Drilling campaign reaches a depth of 808 meters in the Antarctic ice sheet

In Antarctica, the second drilling campaign of the Beyond EPICA—Oldest Ice project, at the remote field site Little Dome C, has been successfully completed....

Vast iceberg breaks off near UK Antarctic base

A huge iceberg nearly the size of Greater London has broken off the Antarctic ice shelf near a research station, the second such split...

Runaway W. Antarctic ice sheet collapse not ‘inevitable’: study

The runaway collapse of the West Antarctic Ice Sheet—which would trigger catastrophic sea level rise—is not "inevitable", scientists said Monday following research that tracked...

New ice core analysis shows sharp Greenland warming spike

A sharp spike in Greenland temperatures since 1995 showed the giant northern island 2.7 degrees (1.5 degrees Celsius) hotter than its 20th-century average, the...

Runaway West Antarctic ice retreat can be slowed by climate-driven changes in ocean temperature

New research finds that ice-sheet-wide collapse in West Antarctica isn't inevitable: the pace of ice loss varies according to regional differences in atmosphere and...

Antarctica’s emperor penguins could be extinct by 2100

Greater conservation efforts are needed to protect Antarctic ecosystems, and the populations of up to 97% of land-based Antarctic species could decline by 2100...

EXPLAINER: Arctic blast sweeps US, bomb cyclone possible

An arctic blast is bringing extreme cold, heavy snow and intense wind across much of the U.S. this week—just in time for the holidays. The...

Study identifies new cause of melting Antarctic ice shelves

Researchers have discovered a process that can contribute to the melting of ice shelves in the Antarctic. An international team of scientists found that adjacent...

Scientists map heat beneath Antarctica’s icesheets

Researchers from the ARC Center for Excellence in Antarctic Science (ACEAS) at the University of Tasmania are helping predict future sea level rise by...

Study shows that strongest Arctic cyclone on record led to surprising loss of sea ice

A warming climate is causing a decline in sea ice in the Arctic Ocean, where loss of sea ice has important ecological, economic and...

Sea level rise to dramatically speed up erosion of rock coastlines by 2100

Rock coasts, which make up over half the world's coastlines, could retreat more rapidly in the future due to accelerating sea level rise. This is...

Ice loss from Northeastern Greenland significantly underestimated

Ice is continuously streaming off Greenland's melting glaciers at an accelerating rate, dramatically increasing global sea levels. New results published today in Nature indicate...
