The political (not scientific) body, The Intergovernmental Panel on Climate Change (IPCC) has reported that temperature changes over the last century are:
- 1910-1940 - an increase of 0.5ºC
- 1940-1970 - a decrease of 0.2ºC
- 1970-2000 - an increase of 0.5ºC
As Nobel Laureate in Physics Richard Feynman, speaking at Cornell University in 1964, said - the guess is wrong. The AGW hypothesis has been falsified. Game, Set and Match.
