Antarctic Warming, Antarctic Cooling

Until recently, the Antarctic ice sheet looked to be bucking the global warming trend. This assessment relied on temperature data collected from a sparse network of mostly coastal weather stations. To provide a more complete picture of Antarctica’s historic surface temperature regime, a team of U.S. scientists employed an innovative technique to construct 50-year estimates of the near-surface temperature anomalies for the entire continent.

Community Ice Sheet Model Will Aid Understanding of Sea Level Rise

thumbnailIf melted, all of the ice on the Earth’s surface could raise global sea level by more than 200 feet. Because most of this ice resides in the ice sheets of Greenland and Antarctica, interest in understanding ice sheet dynamics is growing, particularly among scientists responsible for designing the Community Climate System Model (CCSM), a general circulation model built by the climate modeling community and housed at NCAR.

Education & Outreach

You can explore the atmosphere, too. From the learning games on Kid's Crossing, to Windows to the Universe, there are many ways to learn about our atmosphere, and the scientists who study it.

There are opportunities for undergraduates with internship programs such as SOARS; and Post graduate students should explore the opportunities to work with NCAR, via the Advanced Study Program.

NCAR is committed to developing and enhancing public interest in and understanding of science. Educators can take an online course, view teaching resources by grade-level in the Educator's Bridge, or get up-to-speed on Weather & Climate Basics.
