Potential for Antarctic Climate Change
Antarctica has cooled over the last 30 years, but the trend is likely to rapidly reverse, according to a new study which examines the effect of depleted ozone and increasing greenhouse gases. (Oct. '04)

Mars: Signs of a Watery Past
"Follow the water" has been NASA's chief guideline for the exploration of Mars. Evidence is rapidly accumulating from satellites and roving landers that the Red Planet was once much wetter, with a more clement climate. (Oct. '04)

Methane: Climate Super-Star
In 30 years, our knowledge of methane has traveled from obscure trace gas to important greenhouse forcing, both natural and anthropogenic. What caused this change, and what role has methane played in climate, both in the past and future? (Sep. '04)

Modeling Ocean Deep Convection
The unique physical characteristics of the oceans are largely responsible for making the Earth a livable environment. Of particular interest is the the role deep convection plays in the ocean's conveyor belt of thermohaline circulation. (Aug. '04)

Observing and Modeling African Storms
Regional climate models give more detailed structure to the spatial distributions of weather variables. After a few days of initial tuning, one GISS model simulates realistic weather scenarios such as summer storms over West Africa. (July '04)

GISS Model E Source Code
The new GISS coupled atmosphere-ocean model has been frozen and the FORTRAN 90 code is available for download. The model is a complete rewrite of the GISS Model II', with improved physics and flexibility and more options. (Mar. '04)

Atmospheric Tango
Ozone affects climate, and climate affects ozone. Temperature, humidity, winds, and the presence of other chemicals in the atmosphere influence ozone formation, and the presence of ozone, in turn, affects those atmospheric constituents. (Feb. '04)
