Dr. David Legates, Professor of Climatology, University of Delaware, has filed today his requested statement to the Environment and Public Works Committee of the US Senate. Dr. Legates finds"My overall conclusion is that droughts in the United States are more frequent and more intense during colder periods. Thus, the historical record does not warrant a claim that global warming is likely to negatively impact agricultural activities."
Dr. Legates concludes with his experiences with post-normal climate science, Climategate, the Mann hockey stick, and silencing of dissenters & Lysenkoism prevalent in climate science today."Given the limitations of the models not only in predicting global air temperatures but also in estimating precipitation and soil moisture conditions, it seems that a more reasonable approach is not to rely on the model prognostications; but rather, to focus on policies that allow for adaptation to the observed variability in precipitation and soil moisture. Droughts that have happened in the past are likely to occur again, and with likely similar frequencies and intensities; thus, preparation for their return is a better strategy than trying to mitigate them through draconian CO2 emission control policies."
