Intergovernmental Panel on Climate Change Adopts Major Assessment of Climate Change Science

Paris, 2 February 2007 – Late last night, Working Group I of the Intergovernmental Panel on Climate Change (IPCC) adopted the Summary for Policymakers of the first volume of “Climate Change 2007”, also known as the Fourth Assessment Report (AR4).

“Climate Change 2007: The Physical Science Basis”, assesses the current scientific knowledge of the natural and human drivers of climate change, observed changes in climate, the ability of science to attribute changes to different causes, and projections for future climate change.

The report was produced by some 600 authors from 40 countries. Over 620 expert reviewers and a large number of government reviewers also participated. Representatives from 113 governments reviewed and revised the Summary line-by-line during the course of this week before adopting it and accepting the underlying report.

The Summary can be downloaded in English from http://www.ipcc.ch/ and http://ipcc-wg1.ucar.edu/. A webcast of the final press conference has also been posted. The Summary will be available in Arabic, Chinese French, Russian and Spanish at a later date. The full underlying report will be published in English by Cambridge University Press.

From the IPCC website:
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. It is currently finalizing its Fourth Assessment Report "Climate Change 2007". The reports by the three Working Groups provide a comprehensive and up-to-date assessment of the current state of knowledge on climate change.

Climate Change 2007 - A comprehensive and rigorous picture of the global present state of knowledge of climate change.
- 2500+ Scientific Expert Reviewers
- 800+ Contributing Authors
- 450+ Lead Authors from 130+ Countries
- 6 Years of Work
- 4 Volumes
- 1 Report

The Conclusion: There is a 90 percent certainty that global warming is man-made as reported by scientists and representatives of 113 governments. The situation is an existing and worsening threat to the environment and inhabitants of earth, including an increase in storm risk and intensity, and a rise of sea level by 23 inches by 2100.
