(Newser) – From the damned-if-you-do department: A new study has found that wind farms, those environmentally friendly sources of clean, renewable energy, could be contributing to global warming, reports the Telegraph. The problem is that the giant propellers cause the air to circulate more. That means that during the night warmer air from higher up in the atmosphere is pulled down to mix with cooler ground temperatures. The net effect is higher temperatures.

Satellites have shown that the air around parts of Texas that are home to four of the world's largest wind farms went up nearly 1.4 degrees when the wind farms were built. But experts warn people not to get too carried away by these latest findings. “Overall, the warming effect reported in this study is local and is small compared to the strong background year-to-year land surface temperature changes,” said one environmental scientist.

Everyone needs to keep in mind that no actual climate scientist would call this an increase in GLOBAL warming, that is only being done by non-scientist news headline writers, because it gets peoples attention. Mixing different temperatures of air together does not change the global or total temperature. In fact, since the energy for storms comes from the dynamic between weather fronts of different temperatures, pre-mixing hot and cold air like this actually makes storms less likely to happen, because it increases thermodynamic equilibrium. Also, most people would probably prefer it be a couple of degrees warmer at night.

I don't know about climate change, but they sure do cause noise pollution. Plus, they are now being built close to highways and waterways and this is sad because they are destroying some of the most beautiful views.

“Overall, the warming effect reported in this study is LOCAL" yet the title says "Latest GLOBAL Warming Culprit: Wind Farms" Local = Global??? STFU!
