This feature article provides a summary of study about the role of clouds in the balance. Until recently, scientists were uncertain whether clouds had an overall net cooling or heating effect on the Earth's climate. But recent studies show that, in the tropics, a "near cancellation" between shortwave cooling and longwave warming exists, which indicates that the amount of incoming radiant energy is roughly equal to the amount of outgoing radiation. However, small changes in tropical cloudiness can disrupt this precarious balance.

The Washington International Renewable Energy Conference (WIREC 2008) convened from 4-6 March 2008, at the Washington, DC Convention Center in the US.

On 1 March 2007, the International Polar Year 2007/2008, one of the most ambitious coordinated international science programmes was launched. Many of the IPY leaders and participants are members of WCRP projects and groups. Climate issues are at the forefront of the majority of IPY studies. This chart is a visualization of International Polar Year activities at the World Climate Research Program.
