(60,320 posts)While it is true that in physics for every action there is a reaction and therefore technically the wind does slow down when it pushes on a a turbine blade, ... to insist on that point, especially without explaining it, and without discussing the context, is to miss the boat.
The amount the wind slows down is little, and even then only if there is a concentration of wind devices.
In the wider context of the world's weather and climate, the effect is negligible and possibly so small to be not measurable. There is so much wind all over the world that wind farms are not a factor.
As to whether slower wind makes the world infinitesimally warmer, I don't know, but on the face of it a case could be made for both sides. Faster wind could be more efficient transporting solar heated air around the world. On the other hand, at least locally, slightly more stagnant air may heat up more.
Once again, the effect will be negligible and perhaps too small to measure.
On the other hand, standing on the technicality gives aid and comfort to the oligarchy who are more concerned about their profits than our children and grandchildren.
