Wind farms can cause climate change, finds new study
Wind farms can cause climate change, according to new research, that shows for the first time the new technology is already pushing up temperatures.

Usually at night the air closer to the ground becomes colder when the sun goes down and the earth cools.
But on huge wind farms the motion of the turbines mixes the air higher in the atmosphere that is warmer, pushing up the overall temperature.
Satellite data over a large area in Texas, that is now covered by four of the world’s largest wind farms, found that over a decade the local temperature went up by almost 1C as more turbines are built.
This could have long term effects on wildlife living in the immediate areas of larger wind farms.
It could also affect regional weather patterns as warmer areas affect the formation of cloud and even wind speeds.
It is reported China is now erecting 36 wind turbines every day and Texas is the largest producer of wind power in the US.
Liming Zhou, Research Associate Professor at the Department of Atmospheric and Environmental Sciences at the University of New York, who led the study, said further research is needed into the affect of the new technology on the wider environment.
“Wind energy is among the world’s fastest growing sources of energy. The US wind industry has experienced a remarkably rapid expansion of capacity in recent years,” he said. “While converting wind’s kinetic energy into electricity, wind turbines modify surface-atmosphere exchanges and transfer of energy, momentum, mass and moisture within the atmosphere. These changes, if spatially large enough, might have noticeable impacts on local to regional weather and climate.”
The study, published in Nature, found a “significant warming trend” of up to 0.72C (1.37F) per decade, particularly at night-time, over wind farms relative to near-by non-wind-farm regions.
The team studied satellite data showing land surface temperature in west-central Texas.
“The spatial pattern of the warming resembles the geographic distribution of wind turbines and 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,” said Prof Zhou.
However Prof Zhou pointed out the most extreme changes were just at night and the overall changes may be smaller.
Also, it is much smaller than the estimated change caused by other factors such as man made global warming.
“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,” he added.
The study read: “Despite debates regarding the possible impacts of wind farms on regional to global scale weather and climate, modelling studies agree that they can significantly affect local scale meteorology.”
Professor Steven Sherwood, co-Director of the Climate Change Research Centre at the University of New South Wales, said the research was ‘pretty solid’.
“This makes sense, since at night the ground becomes much cooler than the air just a few hundred meters above the surface, and the wind farms generate gentle turbulence near the ground that causes these to mix together, thus the ground doesn’t get quite as cool. This same strategy is commonly used by fruit growers (who fly helicopters over the orchards rather than windmills) to combat early morning frosts.”

The Left’s Presumption of Superiority
Written on March 16, 2012 by David L. Goetsch
Conservative economist Thomas Sowell once wrote: “People are never more sincere than when they assume their own superiority.” I could not have said it better. Having spent 36 years in that bastion of presumed superiority—higher education—I am accustomed to people who simply assume they are superior, and then act accordingly. I once debated a fellow professor whose academic background was philosophy. My field was business. He was decrying the fact that so many college students now choose to pursue degrees in professional fields such as engineering or business rather than the traditional liberal arts (i.e. Humanities, Philosophy, and Art). This professor wore his presumed intellectual superiority like a badge of honor and virtually dripped righteous indignation as he spoke.
After listening to my snooty colleague repeatedly refer to business majors as “baby capitalists” and engineering majors as “glorified auto mechanics,” I interrupted and asked him two questions: 1) What is wrong with capitalists and auto mechanics? and 2) Next time your car breaks down, why don’t you call a philosopher? The audience enjoyed the intended humor in my questions and laughed accordingly. But my colleague was greatly offended that someone would dare question his obvious superiority. He responded that I was “stupid” and stomped off the stage in a huff.
This debate took place in an academic environment where righteous indignation permeates the very bricks and mortar. College professors and their liberal counterparts outside of the academy are what Thomas Sowell once referred to as the “perpetually indignant.” When liberals cannot rebut conservative ideas with logic or reason, they simply brush them aside and call them “stupid” or “unworthy.” When a conservative gets under their skin with an argument based on those inconvenient little things known as facts, liberals quickly resort to name calling. For example, make a cogent, well-reasoned argument against any of President Obama’s misguided economic policies and see how long it takes before liberals call you a “racist.”
In discussions and debates, liberals seldom attempt to explain themselves or to offer more viable ideas. To liberals who are blindly invested in their own intellectual and moral superiority, explanations are not necessary. To them, the viability of leftist opinions should be self-evident, a convenient defense for those who cannot justify their opinions on the basis of logic, reason, or facts. This is why colleges and universities are such comfortable places for liberals.
On most college campuses in America, liberals know they are among like-minded colleagues who share the same presuppositions. By associating exclusively with fellow travelers, liberal professors eliminate the inconvenience of having to defend their opinions. Hence, they quickly become intellectually flabby. On the typical college campus in America a conservative is about as welcome as a roach in the punch bowl, and a business leader is welcome only if he is there to make a substantial donation. In this type of environment a liberal is free to pontificate without any fear of being challenged by logic, reason, or facts.
In his book, The Thomas Sowell Reader, Sowell summed up the left’s presumed superiority in these words: “It would never occur to people with academic degrees and professorships that they are both ignorant and incompetent in vast areas of human life, much less that they should keep that in mind before they vent their emotions and wax self-righteous. Degrees show that you have knowledge in some special area. Too often they embolden people to pontificate on a wide range of subjects where they don’t know what they are talking about.”
As he typically does, Sowell hit the nail on the head. He too has spent years in an academic environment surrounded by intellectual elites who believe so fervently in their own superiority that they brush aside conservative arguments like annoying flies at a picnic. To his credit, Sowell never dons the armor of presumed superiority. He does not need to because, although in a league of his own compared with most professors, Sowell’s arguments are always backed by logic, reason, and facts. Unlike liberals, Sowell knows that it is his logic, reason, and facts that must be superior. There is a lesson here that liberals would do well to learn.
