And what about those crazy, whacked out Solar Physicists?
Twenty years ago, climate research became politicised in favour of one particular hypothesis, which redefined the subject as the study of the effect of greenhouse gases.But hey, screw it... it's easier just to hitch a ride with Al "Pinochio" Gore.
The best measurements of global air temperatures come from American weather satellites, and they show wobbles but no overall change since 1999. That levelling off is just what is expected by the chief rival hypothesis, which says that the sun drives climate changes more emphatically than greenhouse gases do.
Solar physicists warn of possible global cooling, should the sun revert to the lazier mood it was in during the Little Ice Age 300 years ago.
What does the Intergovernmental Panel do with such emphatic evidence for an alternation of warm and cold periods, linked to solar activity and going on long before human industry was a possible factor?
Less than nothing.
You can trust Big Al.
