To all those deniers who claimed the record cold in January & February in parts of the Northern Hemisphere (and again in December in Britain) proved global warming was a hoax… In fact globally 2010 equalled 2005 as hottest year ever overall, being 0.62C warmer than the twentieth century average (~14C globally). Deniers looked away from a 2 month heatwave across Russia, and in fact land temperatures were the highest ever, a full degree higher. The sea was 0.49 degrees warmer, the third highest ever.
In fact now 9 of the hottest 10 years are now since 2000. The outlier? The third hottest year was way back in 1998. The data disproves unequivocally claims that climate warming ended in 2005, another straw some deniers grasp at.
Last year was also the wettest on record, and with the third least Arctic ice (after 2007 & 2008).
Now we just need some action, rather than the collapse of Cancun and National’s gutting of the ETS, to leave us paying the polluters.
Old xkcd, playing devil’s advocate:
