Cover crops grown in fields during winter may be warming temperatures in the northern United States and southern Canada, according to a new study by scientists at the National Center for Atmospheric Research. The crops, a land management strategy farmers use between growing seasons, create a darker surface than a snow-covered field, absorbing more heat from the Sun and producing a local warming effect.

New research by NASA and NCAR has found that increases in the rate at which Arctic sea ice grows in the winter may have partially slowed down the decline of the Arctic sea ice cover.

Everette Joseph was named director of the National Center for Atmospheric Research today, following a rigorous international search. He joins NCAR from the University at Albany, State University of New York, where he is director of the Atmospheric Sciences Research Center.

UCAR congratulates Senators Cory Gardner and Gary Peters for winning the 2018 American Geophysical Union (AGU) Presidential Citation for Science and Society.

The pattern of uneven sea level rise over the last quarter century has been driven in part by human-caused climate change, not just natural variability, according to a new study.
