IPCC to release major report on the science of climate change

Geneva, 22 January 2007 " The Summary for Policymakers of the first volume of “Climate Change 2007”, the Intergovernmental Panel on Climate Change (IPCC) new assessment report, will be released on 2 February in Paris. The, Working Group I (WGI) contribution to the Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change (IPCC), will be finalised at the 10th Session of WGI which will take place in Paris from 29 January - 1 February. Government delegates at this Session will approve the Summary for Policymakers of the report line by line, and then accept the underlying report. The WGI report, “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 includes significantly advanced observations of the climate system, presents new projections of future global climate change using results from 19 climate models, all with improved representations of physics, chemistry, and spatial resolution. The report also covers the range of anthropogenic greenhouse gases and other factors that drive climate change. There will also be a Chapter assessing the paleoclimatic perspective. The WGI report does not cover the impacts of climate change or options for the mitigation of climate change. These aspects will be covered in subsequent reports by Working Group II (impacts, adaptation and vulnerability), and Working Group III (mitigation options) to be finalised respectively in early April and early May this year In addition a Synthesis Report covering key findings of all three Working Groups will be released in late 2007.
