COSMIC satellites have provided a reliable thermometer in the sky.

Winds not only influence waves, but waves influence the atmosphere as well.

Software engineers and scientists collaborate to visualize research.

This visualization shows how September sea ice in the Arctic could disappear by the end of this century.

Scientists propose a new approach for determining the influence of climate change on aspects of extreme weather events.

Many storms from the 1980s or earlier would probably appear in the record as bigger storms if the observers had used currently accepted methodology.

There's major disagreement among scientists on exactly what might be causing a tendency toward colder winters over the last few years in places like the central and eastern United States, Europe, and Russia.

Known from their frequent film and TV appearances, the large, charismatic birds are in danger. By 2100, according to a new study, their numbers will have fallen by around 19% and will continue to decline, qualifying the species for endangered status.

How does the U.S. winter of 2013–14 rank against its predecessors? And was it a harbinger of more cold winters to come for parts of the country, or simply an outlier at a time of largely warming winters?

In parts of California and Oregon, 2013 was the driest calendar year on record, with no sign of relief on the horizon. NCAR scientists are examining how water and energy use intersect across this drought-prone region and how the nexus could evolve in a future climate.

It’s hard to escape the cold now plowing into the eastern United States. Amid all the hype, what stands out about this early winter onslaught?
