But Monckton is defending himself "At least I got the science right". No you didn't, Monckton.
"In 1988, James Hansen, a climatologist, told the US Congress that ... sea level would rise several feet"
- he said no such thing. Although fiction writer Michael Crichton, basing his claims on dubious analysis of Hansen's work by Michaels (who deleted plots off of Hansen's graph) alleged he did.
"Scores of scientific papers show that the medieval warm period was real, global and up to 3C warmer than now. Then, there were no glaciers in the tropical Andes: today they're there. "
And they're getting ice cores from them. That go back earlier than the European medieval warm period. (doi 10.1002/1099-1417). Explain that one if they melted.
There was little ice at the North Pole: a Chinese naval squadron sailed right round the Arctic in 1421 and found none.
Complete fiction. It's mentioned in one book, and no historian has ever found any evidence whatsoever for this happening. You might as well base your theories on CS Lewis!
And so on, and so forth.
It would appear the Sunday Telegraph has declared war on science.
