Wind is a limited resource, and by putting up all these turbines, we've critically increased the planet's drag and reduced aerodynamic efficiency. This means the wind is getting trapped so there's less air circulation, severely hampering the refreshing breezes that have long been critical to our planet's cooling process. This is the real cause of global warming.
Yup, contrary to what the lib enviro wackjobs would tell you, wind power isn't a solution to global warming, IT'S THE CAUSE!!!!
