Here is a study of climate in Central Canada during the twentieth century.

St. George, S. 2007. Streamflow in the Winnipeg River Basin, Canada: Trends, Extremes and Climate Linkages. Journal of Hydrology, 332, pp., 396-411.

This paper studies temperature in the Winnipeg River Basin from 1924 to 2003 and found no temperature change, monthly, seasonal, or annual. That is not surprising to me, but it goes against what is predicted by the Global Circulation Models used to predict coming climate catastrophe. The GCMs predict the most temperature increase in the center of Northern land masses such as central Canada. I wonder how James Hansen and Al Gore will explain this. Probably they won't, since there is a "scientific consensus on Global warming, there is no need to look at actual data. No doubt this St. George fellow ought to be out slaying dragons, not casting doubt on the "scientific consensus."
