Climatologist Dr. David LEGATES TELLS U.S. Senate: ‘Droughts in the U.S. are more frequent and more intense during colder periods’

Climatologist Dr. David Legates: “Droughts in the United States are more frequent and more intense during colder periods”

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.”

“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.”

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.

David R. Legates, Ph.D., C.C.M.

University of Delaware

3 June 2014

I am a Professor of Climatology at the University of Delaware and I served as the Delaware State
Climatologist from 2005 to 2011. I also am an adjunct faculty member in the Department of
Agricultural Economics & Statistics and the Physical Ocean Science and Engineering Program.
I received a B.A. in Mathematics and Geography, a M.S. in Geography, and a Ph.D. in
Climatology, all from the University of Delaware. I served on the faculty of the University of
Oklahoma and Louisiana State University before returning to the University of Delaware in
1999. I was part of the US delegation that negotiated a protocol for the first climate data
exchange program with the Soviet Union in 1990. I am recognized as a Certified Consulting
Meteorologist by the American Meteorological Society and was the recipient of the 2002 Boeing
Autometric Award in Image Analysis and Interpretation by the American Society of

Photogrammetry and Remote Sensing.

Scientist tells U.S. Senate: Global Warming Not Causing More Wildfires – ‘To attribute this human-caused increase in fire risk to carbon dioxide emissions is simply unscientific’

Government wildfire data shows that the scale of U.S. wildfires has decreased dramatically since 1930, when wildfires burned more than four times the amount of acreage burned in 2012. In 1930, wildfires consumed more than 50 million acres of land, but in 2012 wildfires only burnt up 9.2 million acres.

According to the National Oceanic and Atmospheric Administration (NOAA), carbon dioxide concentrations were much lower in the 1940s (only 310 parts per million by volume), meaning global temperatures were cooler while wildfires were much more prevalent than today.

“These data suggest that extremely large megafires were 4-times more common before 1940,” South said, adding that “we cannot reasonably say that anthropogenic global warming causes extremely large wildfires.”

“However, in today’s world of climate alarmism, where accuracy doesn’t matter, I am not at all surprised to see many journalists spreading the idea that carbon emissions cause large wildfires,” South said.
