Intergovernmental Panel on Climate Change 4th Assessment Report
News story originally written on February 1, 2007

The 4th Assessment Report Summary for Policymakers of the Intergovernmental Panel on Climate Change (IPCC) is scheduled to be released on February 2, 2007 in Paris, France. The IPCC has been established to assess scientific, technical and socio- economic information relevant for the understanding of climate change, its potential impacts and options for adaptation and mitigation. This summary will provide information on recent progress made in understanding and attributing climate change, what observations tell us, how climate has changed in the past, and projections of future changes.
