All Scientists are Sceptics ~Professor Bob Carter

Whenever someone asserts that a scientific question is “settled,” they tell me immediately that they don’t understand the first thing about science. Science is never settled. Dr David Deming

Perhaps the most frustrating aspect of the science of climate change is the lack of any real substance in attempts to justify the hypothesis ~Professor Stewart Franks

Warming Wind Farms

Previously This Blog has reported to you of wind farms exploding, of wind farms collapsing, of wind farms harming human health and of wind farms killing bats and birds.

Gee, but surely there must be a good side? you ask.

Surely they are preventing the terribly destructive "global warming?"

(For previous TCS blog comment see eg here, here, here and here.)

Well, do wind farms prevent disastrous runaway global warming?

Actually, they assist the warming of the planet.

A new paper published in Nature Climate Change (2012) doi:10.1038/nclimate1505
exposes the truth.

The paper: - Impacts of wind farms on land surface temperature
The wind industry in the United States has experienced a remarkably rapid expansion of capacity in recent years and this fast growth is expected to continue in the future1, 2, 3. While converting wind’s kinetic energy into electricity, wind turbines modify surface–atmosphere exchanges and the transfer of energy, momentum, mass and moisture within the atmosphere4, 5, 6. These changes, if spatially large enough, may have noticeable impacts on local to regional weather and climate. Here we present observational evidence for such impacts based on analyses of satellite data for the period of 2003–2011 over a region in west-central Texas, where four of the world’s largest wind farms are located7. Our results show a significant warming trend of up to 0.72 °C per decade, particularly at night-time, over wind farms relative to nearby non-wind-farm regions. We attribute this warming primarily to wind farms as its spatial pattern and magnitude couples very well with the geographic distribution of wind turbines.
