“Global warming is not a global crisis” declared the Heartland Institute, organiser of the “International Conference on Climate Change”. Heartland is a well-known right-wing lobby group which accepted more than half a million dollars from oil giant ExxonMobil between 1999 and 2005, according to Exxon documents disclosed by Greenpeace, and thousands of dollars more from the tobacco industry.
Not surprisingly, in a statement issued Tuesday, they insisted that all efforts “intended to reduce emissions of CO2 be abandoned forthwith”.
“Manmade global warming is a total hoax. It has no basis in fact,” shouted Rush Limbaugh, a U.S. conservative radio host, on his Feb. 27 show, which draws as many as 13 million listeners.
“Record snows and cold are being reported from all over the northern hemisphere this winter,” Limbaugh claimed.
There is more to the northern hemisphere than the U.S. and Canada. Yes, it has also been cold in China and the Middle East, but it has also been very warm in Britain and most of Europe. In early February, it was balmy 14 degrees C in Edinburgh, Scotland, which is the city’s normal average temperature in July. In Moscow, Russia, the most northern capital city in the world, the forecast this week is rainy and about 3 degrees C, instead of the normal snowy and -10 degrees C.
These temperatures prove nothing. It is just weather. However, climate is completely different than the daily variations in temperature in any one place. Climate is the total of all weather occurring over a period of years in a given place. A cold January means it is winter in the U.S., nothing more.
But Limbaugh went on to claim that NASA’s Goddard Institute for Space Studies latest data shows that “global temperatures have dropped precipitously” in the last year, when in fact NASA reported that 2007 was the second warmest year on record.
