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.

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.

In a sign of the far-ranging effects of space weather, new research shows that a major 1972 solar storm caused the explosions of more than two dozen sea mines.

Currently, half of the world's measured precipitation that falls in a year falls in just 12 days, according to a new analysis of data collected at weather stations across the globe. By century's end, climate models project that this lopsided distribution of rain and snow is likely to become even more skewed, with half of annual precipitation falling in 11 days.
