"Pretty much all of 20th century global warming may have been erased within 4 days"

The Reference Frame: The globe cooled by 0.56 °C in four days

The cooling between December 23rd and December 27th, 2010 is a whopping 0.56 °C. Pretty much all of 20th century global warming may have been erased within 4 days - the same time that Apollo 11 needed to get to the Moon, as correctly predicted by Jules Verne. ;-)
