Run For The Hills!

clipped from wattsupwiththat.com Figure 3. US decadal average temperatures by month, 1900-2009. Red line is the average for the decade 2000-2009. Photo is Half Dome, Yosemite. Most months of the year there is so little change in the decadal averages that the lines cannot be distinguished. The warming, what there is, occurred mostly in the months of November, December, January, and February. Slightly warmer temperatures in the winter … somehow, that doesn’t strike me as anything worth breathing hard about. My point in all of this is that the temperature changes that we are discussing (a global rise of a bit more than half a degree C in the last century) are trivially small. A half degree change cannot be sensed by the human body. In addition, the changes are generally occurring in the winter, outside of the tropics in the cooler parts of the planet, and at night. Perhaps you see this small warming, as has often been claimed, as a huge problem that “vastly eclipses that of terrorism” (the Guardian).
