Studies of historical tree ring data in southern Alberta show a trend in the South Saskatchewan River Basin flows over the past 600 years. This data indicates that flood and drought events in the past WERE FAR MORE SEVERE than we have experienced during the mid-to late-20th-century. (emphasis added)
This story of yet another failure of global warming come from Power Line:
A reader up in the Great White North directs our attention to the fact that Manitoba and Saskatchewan are both suffering from severe flooding at the moment, which automatically sets off talk of . . . now wait for it, darn it . . . climate change! There’s just one inconvenient problem: a careful study reported yesterday in the National Post finds that extreme precipitation events in the region are less frequent today than over the last several hundred years. This chart tells the story very clearly (click to go to Power Line, where you can make the graphic bigger):
The above coupled with the below via WUWT:
Taking the least-squares linear-regression trend on Remote Sensing Systems’ satellite-based monthly global mean lower-troposphere temperature dataset, there has been no global warming – none at all – for 17 years 10 months. This is the longest continuous period without any warming in the global instrumental temperature record since the satellites first watched in 1979. It has endured for more than half the entire satellite temperature record. Yet the lengthening Pause coincides with a continuing, rapid increase in atmospheric CO2 concentration….

Al Gore said ALL the ice was suppose to be gone in the Arctic by now. Oooops.
