From the BBC:
Wind farms, especially big ones, generate turbulence that can significantly alter air temperatures near the ground, say researchers.
As turbines often stand on agricultural land, these changes could in turn affect crop productivity.[…]
But Jonathan Scurlock, chief adviser on climate change and renewable energy at the National Farmers Union, said that using wind energy was “one of many measures, which can be [used] to mitigate climate change”. “The major threats to agriculture in terms of changing the air temperature come directly from the fossil fuel industry and deforestation, increasing CO2 concentration in the atmosphere,” he added.[…]
But Dr Roy noted that even though wind farms were unlikely to have an effect on global climate change, “the impacts on local climate can be large”.
He also said that the study was not about comparing wind power to any other technology, but about considering and addressing possible side effects of this green energy.
“Wind energy is likely to be a part of the solution of the global warming problem,” he said.
“Often, in a rush to implement new technologies, we ignore possible side‐effects that may show up in the future.
What’s in question is local climate change. In the end, of-course, all climate is local. It doesn’t much matter to you if you’re told the world has gotten two degrees warmer when your house is buried in snow and your pipes are freezing. In any case, the law of unintended consequences continues to rule, while the global warming advocates with their grand schemes to remake the world continue to stumble ahead regardless.
Addendum: And of-course, as has become increasingly well-known, wind turbines are also unbearably loud for people living nearby.
