Meteorologist Chris Martz used the North American Drought Atlas (built from tree-ring data) to track Great Plains drought across the past 1,500 years. It shows severe drought regularly hit the plains long before industrial CO2. The 1818 to 1825 drought stands out. So too does the 1855 to 1865 Civil War drought. The little mentioned 1950s drought is also clear, which followed the devastating Dust Bowl. Further back, the worst known plains drought came during the Medieval Warm Period. It lasted around 400 years with only brief breaks.
