The down side to wind power
&gt;To estimate the impacts of wind power, Keith and Miller established a baseline for the 2012‒2014 U.S. climate using a standard weather-forecasting model. Then, they covered one-third of the continental U.S. with enough wind turbines to meet present-day U.S. electricity demand. The researchers found this scenario would warm the surface temperature of the continental U.S. by 0.24 degrees Celsius, with the largest changes occurring at night when surface temperatures increased by up to 1.5 degrees. This warming is the result of wind turbines actively mixing the atmosphere near the ground and aloft while simultaneously extracting from the atmosphere’s motion.<p>I am confused: How does the warming work exactly and is this actually a global climate effect? Because this part of the article makes it sound to me as if it&#x27;s just a very localised change of temperature caused by the exchange of different air layers, which can&#x27;t be right? Because you couldn&#x27;t really compare that to climate change on a global scale.
