This story [1] is legitimately tragic, but it's far from the first case of climate change delusion. Have they never heard of Benny Peiser [2]? Larry Solomon [3]? Tim Ball [4]? The Viscount Monckton of Brenchley [5]? Bob Carter [6]?
Of course, these guys may not be delusional. They may just be lying. But that would involve a judgment rather than a diagnosis .... And either way, a certain sort of sickness abounds.
