Air turbulence from giant turbines causes air temperatures to rise around wind farms, scientists say. Researchers … examined conditions around 2,358 turbines at four Texas wind farms. [They] reported a temperature increase of up to 0.72 degrees Celsius per decade at wind farm locations, compared to nearby areas.
“Turbine rotors were modifying surface-atmosphere exchanges and the transfer of energy, momentum, mass and moisture within the atmosphere,” they wrote. [T]he results match modeling studies showing wind farms can significantly affect local scale meteorology by increasing surface roughness, changing the stability of the atmospheric boundary layer, and enhancing turbulence in the wake generated by rotor blades.

The rest of the article is a “yeah, but.” They try to say it’s a minor effect (which is probably is) that’s offset by taking CO2 producers out of the energy-production process (which it doesn’t). Since wind generation is variable, no coal/nuke/gas plants have been taken off line; because they have to be available when the wind dies and to accommodate peak demands. They just don’t count that unproductive CO2 in the “offsets” and “savings.”* There ain’t no such thing as a free lunch in nature or anywhere else.
Nature doesn’t care how friggin’ brilliant one thinks one’s idea is.
