This was sent to me by Ross McKitrick, a man who knows how to ruin an Englishman’s afternoon with a single e-mail.
The Canadian Government, fresh from doubling its estimate of how much the Kyoto Protocol will cost the Canucks, and without a clue as to what to do about
crashing the Canadian economy mitigating the effects of future climate change, has sent these materials out to the proud educators of those lucky young Canadians of school age, in order to frighten them with a ludicrous extrapolation from only a few years’s data, all the way to the year 2100.
Apparently there’s some nice big posters to go on the walls and everything. Just in case the kids get too rowdy, they are to be put in front of it and told "this is your future unless you behave!"
That’ll teach ‘em. It’s the climate science version of "tough love"
Yup. It’s yet another reproduction of the same graph. Nobody appears to be using Moberg (2005) (too young?) or Esper (2002) (too Dutch?) or even Crowley (2000) (too invisible?), despite pleadings from realclimate. I could be wrong, but perhaps the reason they are not used, is that they are simply not scary enough.
Scary, in the sense that the Canadian government would have us believe that the current warming is more than happened during the MWP, the Roman Warm period and even the Holocene maximum! The projection of dramatic warming from wild extrapolation of the weak warming since the 1960s is a nice touch. The two graphs above aren’t even consistent with each other, the upper one shows a temperature anomaly for the present of more than 2oC and the lower one less than 1oC.
Has someone in the Canadian government not been reading Scientific American recently? Someone should tell them that the Mann Hockey Stick does not recontruct the Medieval Warm Period or the Little Ice Age, and that simply writing those two events across the top of the graph does not make it so.
