Frankly, if I wanted to worry about climate change, I would worry
about global cooling again, since the sun is behaving very weakly just now, and sun - watching scientists have even dared to suggest that a reprise of the Little Ice Age is in the offing.
«After rising rapidly during the first part of the 20th century,
global average temperatures did
cool by
about 0.2 °C after 1940 and remained low until 1970, after which they began to climb rapidly
again.
Maybe some direct comparison here could help — something along the lines of noting the history of their rejections of AGW, eg how they've back - pedalled on the «since 1998 it's been
cooling», to (Bob Carter's) «since 2002 it has been
cooling», then the way in which they counter 2005 being the hottest year by saying 1934 was (but conveniently forgetting the bit
about that being only the USA, all of 2 % of the
global surface area), and then finally (Bob Carter
again) «recently it has been
cooling».
