You are right. Major wind turbines disrupt the natural flow of the air. Nature uses wind to transport air heat and to to equate (moderate) temperatures among differents areas.
Major windmills are definitely negatively affecting earth climate. Studies have been done, but buried.
All that messing up the earth climate does not matter! We need to save the earth!
We've got an absolute sh*tload of them in North Central Indiana due to flat rural land. What is the effect? I'm interested.
