Scientists have used tree-ring data from the American Southwest to reconstruct a 1,100-year history of the El Niño cycle that shows that, when the earth warms, the climate acts up. The research may improve scientists’ ability to predict future climate and the effects of global warming.
A new report by the World Resources Institute showcases IRI’s efforts to get decision makers in Indonesia to change their fire policy, so that it was based on seasonal climate information.
Though weak El Niño conditions still exist, it appears that the climatic phenomenon that developed over the course of last summer has finally begun to dissipate. As reported earlier, El Niño is the name given to sustained sea surface temperature (SST) anomalies greater than 0.5°C across the central tropical Pacific Ocean. It is the warm [...]
As Haitians struggle to rebuild their country after January’s devastating earthquake, they face added risks, related to climate. Currently, about 1.2 million Haitians are without proper shelter, and an additional 470,000 have been displaced from their homes, according to the U.N. Office for the Coordination of Humanitarian Affairs (latest updates). This leaves them vulnerable to storms and extreme [...]
The International Research Institute for Climate and Society (IRI) has recently released a series of documents designed to walk policymakers through the potential impacts of the current El Niño. In addition to the health-related report featured earlier, two new papers highlight weather and socioeconomic concerns associated with current climatic conditions. As readers of this blog [...]
Forecasts by the International Research Institute for Climate and Society and other institutions show that a weak El Niño has developed in the equatorial Pacific, and is likely to continue evolving with warmer-than-normal conditions persisting there until early 2010. What exactly is this important climate phenomenon and why should society care about it? Who will [...]
