Critically important article finds the Windows man guilty of inventing his own reality. Science doesn’t care about wealth.
The press doesn’t get away unscathed: “The legacy media is apparently more interested in the climate musings of an erstwhile PC mogul than a sober assessment by the world’s leading climate scientists.”
