Brown earned his "Moonbeam" moniker
Brown has given quite a few examples where he is as much of a science denier as Trump. One was when the Mediterranean Fruit Fly was causing havoc in Nor Cal, most scientists agreed that Malathion was a safe pesticide to use, but he went through the effort of finding one that disagreed. Another is his opposition to nuclear energy, if CO2 is so bad, why is he so intent on shutting down the let plant operating in the state?
He is also one heck of a hypocrite, using state resources to determine the oil/gas potential of his property.
