Wind Turbines, Delta Smelts Vs Drought: What Happens When We Mess with Mother Nature?

Remember Global Warming? Some said  'green energy' would  solve the problem.
Here's a New Revelation:  "Wind Turbine farms are warming the earth, researchers say: "New research finds that wind farms actually warm up the surface of the land underneath them during the night, a phenomenon that could put a damper on efforts to expand wind energy as a green energy solution.
Researchers used satellite data from 2003 to 2011 to examine surface temperatures across as wide swath of west Texas, which has built four of the world's largest wind farms. The data showed a direct correlation between night-time temperatures increases of 0.72 degrees C (1.3 degrees F) and the placement of the farms.
.....
Analysts say wind power is a good complement to solar power, because winds often blow more strongly at night while solar power is only available during daytime hours. But Zhou and his colleagues found that turbulence behind the wind turbine blades stirs up a layer of cooler air that usually settles on the ground at night, and mixes in warm air that is on top.
That layering effect is usually reversed during the daytime, with warm air on the surface and cooler air higher up."The year-to-year land surface temperature over wind farms shows a persistent upward trend from 2003 to 2011, consistent with the increasing number of operational wind turbines with time," Zhou said.
FAA data shows that the number of wind turbines over the study region has risen from 111 in 2003 to 2358 in 2011, according to the study.The warming could hurt local farmers, who have already suffered through a killer drought over the past few years. Texas agriculture contributes $80 billion to the state's economy, second only to petrochemicals, according to the Texas Department of Agriculture.
West Texas is a dry area that uses irrigation to grow wheat, cotton and other crops, as well as raise cattle. But increased warming can play havoc with plant growth, as well as change local rainfall patterns....It shows that we need to think carefully about the unintended environmental consequences of any large-scale energy development," Dabiri said, "including green technologies."

What about another Governmental law to "save the planet?"
Remember when.."the plight of drought-stricken farmers in California who have been denied access to a major water supply by a judge citing the Endangered Species Act to protect..."the Delta Smelt, a tiny fish?"
Three years into a drought that evokes fears of a modern-day dust bowl, Allen and others here say the culprit now isn't Mother Nature so much as the federal government. Court and regulatory rulings protecting endangered fish have choked the annual flow of water from California's Sierra mountains down to its people and irrigated fields, compounding a natural dry spell....
Unemployment has soared into Depression-era range; it is 40% in this western Fresno County area where most everyone's job is dependent on farming. Resident laborers who for years sweated in fields to fill the nation's food baskets find themselves waiting for food handouts."The water's cut off," complains Robert Silva, 68, mayor of the farm community of Mendota. "Mendota is known as the cantaloupe capital of the world. Now we're the food-line capital."..."http://www.usatoday.com/weather/drought/2009-07-27-drycalifornia_N.htm

Getting back to the Endangered Species Act ..and the Wind Turbines.
Six birds found dead recently in Southern California’s Tehachapi Mountains were majestic golden eagles. But some bird watchers say that in an area where dozens of wind turbines slice the air they were also sitting ducks....
.....Windmills kill nearly half a million birds a year, according to a Fish and Wildlife estimate. The American Bird Conservancy projected that the number could more than double in 20 years if the administration realizes its goal for wind power....The lack of hard rules has caused some at the conservancy to speculate that federal authorities have decided that the killing of birds — including bald and golden eagles — is a price they are willing to pay to lower the nation’s carbon footprint with cleaner wind energy....

What about the Global Warming from Wind Turbines. Are we going to kill off another group of farmers who provide food for humans.

So the Question Remains?

When the Government gets involved to force man-made devices, such as windmills; or laws, governing natural resources, such as water supplies;
who will the Endangered Species Act
save
since they believe farmers and birds
are expendable?

“The reality is that everything we do as human beings has an impact on the natural environment"  and  human life, "..said John Anderson, director of siting policy for the wind-energy association."
