The above chart shows the correlation between the Obama and FDR Administrations and Midwest droughts. Pretend for a moment, using Michael's Mann substitution of Data method that instead of 0-1000, the numbers at the bottom range from 1920-2010, the assume that the range on the left is the relative Progressiveness of the Presidential Administration, finally the purple lines are US Presidents and the black line is Midwest droughts.
As you can see there is as perfect correlation between severe drought and the Administrations of FDR and Obama.
Progressives create droughts. Clearly, the science is settled.
