A report encompassing the work of thousands of climate experts says that "global warming will happen faster and be more devastating than previously thought". "The really chilling thing about the IPCC report is that it is the work of several thousand climate experts who have widely differing views about how greenhouse gases will have their effect. Some think they will have a major impact, others a lesser role. Each paragraph of this report was therefore argued over and scrutinised intensely. Only points that were considered indisputable survived this process. This is a very conservative document -- that's what makes it so scary."
