This Spring, I pointed out a couple of times [here and here] that the inherent flaw in the Global Warming argument was the selection of an unusually low temperature period as a starting point. This results in an upward overall linear trend for all conditions. It is this "cherry picking" of historical data that allows alarmists to make "startling" comments that earth's temperature has increased by about 1° F over more than a century. This chart was used to illustrate the phenomenon:
[illustrative only]Now a post at Icecap by George Taylor, CCM, points out another tall tale using trends. This time, the starting point was from an exceptionally snowy period so that a return to a more normal period would be seen as a dramatic reduction of snow cover in the Northwest.
The top chart was used to "prove" that global warming was causing a dramatic reduction in snow cover. The bottom chart shows the "unabridged" version. Where's Waldo?
The Machiavellian approach of alarmists is obvious: the end [proving global warming] justifies the means [deception and deceit].
