NOAA researchers have built a "time machine" for weather that provides detailed snapshots of the global atmosphere from 1891 to 2008. The system's ability to "hindcast" past weather events is emerging as a powerful new tool for detecting and quantifying climate change.

Seasonal climate forecasts helped the International Federation of Red Cross/Red Crescent save lives and minimize damages during a severe flooding event in West Africa in 2008.
