Paris--The signs of global climate change are clear: melting glaciers, earlier blooms and rising temperatures. In fact, 11 of the past 12 years rank among the hottest ever recorded. After some debate, the scientists and diplomats of the Intergovernmental Panel on Climate Change (IPCC) issued their long-anticipated summary report in February. The summary describes the existence of global warming as "unequivocal" but leaves out a reference to an accelerated trend in this warming. By excluding statements that provoked disagreement and adhering strictly to data published in peer-reviewed journals, the IPCC has generated a conservative document that may underestimate the changes that will result from a warming world, much as its 2001 report did.

More than 2,000 scientists from 154 countries participated in the IPCC process, which will release three more reports this year. This first report examined only the physical science of climate change. Scientists drafted as lead authors prepared chapters on subjects ranging from a historical overview of climate change science to regional projections. Governments and other reviewers then submitted more than 30,000 comments. Finally, the lead authors and diplomats gathered in Paris to review the final document word by word, changing an emphasis here ("unequivocal" triumphed over "evident") or leaving out a controversial finding there.
