Clouds – An Unwelcome Blanket for Arctic Sea Ice?
A study of Arctic climate finds that cloud cover mostly oscillates between two widely different states, which affects our understanding of and ability to predict sea ice decline.

How Carbon Dioxide Controls Earth's Temperature
A new atmosphere-ocean climate modeling study shows that the planet's temperature depends, ultimately, on the atmospheric level of carbon dioxide.

Does Black Carbon Increase Cooling from Clouds?
Soot particles in the atmosphere absorb radiation, but studies suggest their effect on cloud cover and thickness may promote an overall net cooling.

Thumbs Up or Down for Soot Mitigation?
The climatic effects of soot emissions depend greatly on its composition. The result of reducing emissions will vary depending on what sources are targeted.

Cars Emerge as Key Atmospheric Warming Force
A new NASA study indicates that motor vehicles are the greatest contributor to atmospheric warming. They release greenhouse gases that promote warming, while emitting few aerosols that couteract it.
