We're planning to retire the Community Data Portal (CDP) after nearly 15 years of service. The most active datasets will be migrated to the Climate Data Gateway website. We tentatively plan to shutdown the CDP service by Jan 31, 2018. Please contact us with questions or concerns.
IPCC AR4 Report Chapters
Summary: The Intergovernmental Panel on Climate Change (IPCC) has been established by WMO and UNEP 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 information is freely available after registration.

The contribution of Working Group 1 (WG1) to the Fourth Assessment Report (AR4) is entitled: The Physical Basis for Climate Change. The datasets and programs used to generate the figures appearing in Chapter 3 and sea level changes under various scenarios computed by recent AOGCMs (Chapter 10) may be obtained by clicking on the appropriate links below.
