"One study reports simulations that show detectable changes in global climate for very high wind farm usage, on the order of 10% of the world's land area[8]. In a similar way, there are concerns of micro-climate change, in particular for urban areas nearby, due to changed airflow and reduced wind power."

Sure it is only one study, and a very large amount of landmass. But there is still some effect. (this was a study from 2004, there was also a more recent one, but apparently this one has not reached wikipedia yet )
