Over at Open Mind, Tamino has done it again – pointing out errors in the “skeptic” so-called science used to deny global warming.
He reviews the work of Steven Goddard posted at Watts Up With That, which claims that it’s getting increasingly snowy over the Northern Hemisphere — an increase according to his data of 100,000 km2 / year. Whew! That’s a lotta snow.
Here’s some commentary from the post Northern Hemisphere Snow Extent Second Highest On Record:
As discussed on WUWT, the implication is that Northern Hemisphere snow cover has only extended this far south one other time, since Rutgers University started keeping records. Additionally, North American snow extent broke its all time record last week. Canada is normally completely covered with snow in the winter (except for Olympic venues) so the implication is that the US had more snow last week than has been seen in at least the last 44 years.
Two of the fundamental precepts of global warming theory are that the tropics are supposed to expand, and the Arctic is supposed to warm disproportionately and shrink…
Ice age or a fiery tipping point? What do readers think?
Thing is, he’s cherry picking. He picked only the snow extent in December – February for 1989 – 2010.
Tamino, ever skeptical and curious, re-examines the same data but for all months of the year and for the entire record, starting in 1967.
Guess what? A statistically significant decline in snow extent in the Northern Hemisphere of 37,000 km2/year!
More junk science at WUWT…
