Thirty years ago NASA’s James Hansen predicted 4-6 degrees US warming by 2020. We have almost reached 2020, and there has been no net warming in the US since the 1930’s
Hansen tried to hide his incompetence by tampering with the US temperature data, but his best tampering efforts still fell far short of his forecasts.
Hansen also predicted a huge increase in the number of 90 degree days in Washington DC and Omaha. In fact we have seen the exact opposite. The frequency of 90 degree days has plummeted.
James Hansen is completely incompetent and has no idea what he is talking about, but he says the things politicians and journalists want to hear – and has become rich and famous in doing so.
