We look forward to the publication of the fourth Intergovernmental Panel on Climate Change (IPCC) assessment report, which is expected to be published in 2007 according to the following schedule:
IPCC Working Group I report (covering the physical basis of climate change)—February 2007
IPCC Working Group II report (covering climate change impacts, adaptation and vulnerability)—April 2007
IPCC Working Group III report (covering mitigation of climate change)—May 2007
Synthesis Report (covering all three working groups)—November 2007
The IPCC has completed three assessment reports to date, in 1990, 1996 and 2001. The first and second reports provided a firm foundation on which to build climate policy and were influential in developing an international response to climate change, including the United Nations Framework Convention on Climate Change and the Kyoto Protocol. The third report presented important advances in the scientific understanding of climate change and its projected effects and showed clearly the effect of human activities on the climate system.
