Rupert Darwall has a smashing post in the National Review examining the IPCC's cherrypicking and its failure to report the benefits of global warming:
...the summary speaks of rapid price increases following climate extremes since the 2007 report. This negligence amounts to downright dishonesty, as the summary omits mention of one of the principal causes of the 2007–08 spike in food prices, which is highlighted in the main body of the report. It was not climate change that increased food costs, but climate policies in the form of increased use of food crops in biofuel production, exacerbated by higher oil prices and government embargoes on food exports.
