John Christy, director of the Earth System Science Center at the University of Alabama at Huntsville and a lead author of the IPCC’s Third Assessment Report, has publicly criticized the IPCC’s media campaign to generate public alarm about global warming.
On the computer models that form the foundation of the IPCC report, Christy said, "You should approach climate models with a degree of awe and a sense of humor.

Approximately 1.7 billion people, one-third of the world’s population, presently live in countries that are water-stressed (defined as using more than 20% of their renewable water supply, a commonly used indicator of water stress).
Similar assessments indicate that yields of some crops in tropical locations would decrease generally with even minimal increases in temperature, because such crops are near their maximum temperature tolerance and dryland/rainfed agriculture predominates.
The impacts of short-term weather events on human health have been further elucidated since the Second Assessment Report, particularly in relation to periods of thermal stress, the modulation of air pollution impacts, the impacts of storms and floods, and the influences of seasonal and interannual climatic variability on infectious diseases.

 COMMENTS ON THE SECOND DRAFT OF THE THIRD ASSESSMENT REPORT OF THE IPCC
However, after reading through the Report itself I consider that the Policymakers Summary does, in general, give a fair account of the Report itself, and the distortions, exaggerations and ambiguities are to be found throughout the Report.
The Special Report on Emissions Scenarios is the most intensely political of all the IPCC documents, as it provides the basis for future "projections" and all the on-going "impact" studies which are supposed to tell the world what we may expect in the future.
Yet it is continually referred to with approbation in the Third Assessment Report, and used as the basis for many future projections, where the workers have not yet had time to take in the new set of scenarios.

 IPCC - The Third Assessment Report - Working Group I
One of the most important features of the Third Assessment Report is the strengthening of the conclusion that human activity is driving the observed climate change.
Climate models have improved greatly since the Second Assessment Report (1996), and now include factors such as water vapour, ocean heat transport and sea-ice dynamics.
As shown in these three figures, models which take into account only natural climate factors during the last century fail to match the observed increase in global temperatures, while modeling the effect of fossil fuel burning predicts too much climate change.

 New Scientist Breaking News - Rice yields plunging due to balmy nights   (Site not responding. Last check: 2007-11-04)
The UN Intergovernmental Panel on Climate Change (IPCC) currently predicts that without drastic action to halt emissions of greenhouse gases, there will be a rise of 3.6°C in average global temperatures in the coming century.
Cassman agrees that “the increased CO concentration should partly offset the negative effects of higher night-time temperatures.” But he points out that the Los Banos research plots have been subjected to both higher temperatures and higher CO levels, and the negative effects won.
The IPCC's Third Assessment Report in 2001 foresaw the Los Banos results, stating: "In the tropics, where some crops are near their maximum temperature tolerance, yields would decrease generally with even minimal changes in tremperature."
