Some of this climate change may be due to the CO2 emitted to the atmosphere by the burning of fossil fuels over the past century, although an inspection of regional climate data shows most of the Sierra warming occurred from 1910 through the early 1930s, long before the major emissions.

The one, teensy, weensy problem with the wind industry's «save the planet» pitch is that 100 % of the capacity from intermittent and unreliable wind power has to be backed - up 100 % of the time by fossil fuel generators running in the background and burning fuel ALL the time — and, therefore, increases CO2 emissions in the electricity sector.
