What the IPCC left out: the benefits of global warming
Rupert Darwall ■ It needs catastrophe scenarios to sell their ideas || Its most eye-catching claim (in the new WGII report) is that negative impacts of climate change on crop yields are more common to date than positive impacts are. This improbable claim finds only the weakest support in the main body of the report, with its qualification that climate change played a “minor role.” It is, the report states, “extremely difficult” to define a clear baseline from which to assess the impact of climate change, and many non-climate factors are often difficult to quantify. More egregiously, 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.
