I have not read all of this but he may not be a "Climate Change Denier". He may, like me, accept the fact that the climate changes over time, always has, always will. He may also accept, like me, that since mankind's contribution to the change amounts to four-fifths of five-eights of sweet FA there's little we can do about it (as King Knud demonstrated to his lackies, albeit on a slightly different issue). He may also take the view that even if the US embarks on many of the lunatic and hare-brained schemes that are proposed to combat climate change they have as much chance of achieving their aim as I have of becoming the Pope so they may as well not bother.
