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.
Small but Mighty: Virus-sized Pollutants Affect Mexico City Human Health and Climate
Air pollution causes significant human health and environmental
problems; in megacities, with populations in excess of 10 million,
these impacts are magnified.
Modeling the atmosphere at video game speed
Researchers in ESSL and CISL are
looking at how new generations of super-fast Graphical Processing Units
(GPUs) and multicore chips, such as the Cell Broadband Engine, can be
used in atmospheric models.
Community Ice Sheet Model Will Aid Understanding of Sea Level Rise
If 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.
