Antarctica sea ice melts to a record low

The Antarctic Ocean area covered by ice has shrunk to a record low, exposing the thicker ice shelves buttressing Antarctica's ground ice sheet to waves and warmer temperatures, scientists reported Thursday.

New method provides more accurate analysis of old ice

Ice cores are a unique climate archive. Thanks to a new method developed by researchers at the University of Bern and Empa, greenhouse gas concentrations in 1.5 million year old ice can be measured even more accurately. The ...

From glacier ice, a wealth of scientific data

Perched next to a river near a glacier's edge in Greenland, Penn biogeochemist Jon Hawkings and Jack Murphy, senior research coordinator in Hawkings' lab, scooped up samples of frigid meltwater, careful to seal the bottles ...
