Scientists: Natural Variability Dominates In Continental U.S. Drought


Seager et al., 2009 (Southeastern U.S.)“Tree-ring records show that the twentieth century has been moist from the perspective of the last millennium and free of long and severe droughts that were abundant in previous centuries. The recent drought, forced by reduced precipitation and with reduced evaporation, has no signature of model-projected anthropogenic climate change.”

Stambaugh et al., 2011 (Midwestern U.S.)“[D]rought conditions over the period of instrumental records (since 1895) do not exhibit the full range of variability, severity, or duration of droughts during the last millennium. Thirteen decadal to multidecadal droughts (i.e., =10 years) occurred during the last millennium – the longest lasting sixty-one years and centered on the late twelfth century.”

Andreadis and Lettenmaier, 2006 (Continental U.S.)“Droughts have, for the most part, become shorter, less frequent, and cover a smaller portion of the country over the last century.”
