The US Global Change Research Program has released a draft national assessment on climate change (here in PDF) and its impacts in the United States, as required by The US Global Change Research Act of 1990 (which incidentally was the subject of my 1994 PhD dissertation). There has been much excitement and froth in the media.
Here I explain that in an area where I have expertise on, extremes and their impacts, the report is well out of step with the scientific literature, including the very literature it cites and conclusions of the IPCC. Questions should (but probably won't) be asked about how a major scientific assessment has apparently became captured as a tool of advocacy via misrepresentation of the scientific literature -- a phenomena that occurs repeatedly in the area of extreme events. Yes, it is a draft and could be corrected, but a four-year effort by the nation’s top scientists should be expected to produce a public draft report of much higher quality than this.
Since these are strong allegations, let me illustrate my concerns with a specific example from the draft report, and here I will focus on the example of floods, but the problems in the report are more systemic than just this one case….To Read More……
