No one knows how much energy would need to be taken out of the atmosphere before the weather patterns would start to change, but only a fool would ignore the lessons of the recent past, as the planets current guardians we need to stop being so arrogant and take more care over how we harness its resources !!

The "weather" is a result of the earth's atmosphere trying to correct energy imbalances (kinetic and latent) built up by differences in solar insolation over the earth's surface. The sun and moisture are the drivers. The amount of energy in the atmosphere (again latent and kinetic) involved is huge (atomic bomb level of energy for a single supercell thunderstorm) compared to what is taken out by the wind turbines. And most of the energy in summer thunderstorms is driven by the release of latent heat from condensation in the storm, not the wind itself. So "stealing" some energy from the wind will have negligeable impact on the creation or sustainment of thunderstorms. Most changes would only noticeable on the micro-scale and will not impact the larger scale weather systems with any significance. As Amanda points out, there are many more man-made changes that would have a larger impact, such as deforestation (which also changes the surface albedo (reflectance of solar insolation) of large areas of land and the expansion of cities (heat island effects) than worrying about inconsequential energy loses from large numbers of wind turbines.

Who takes into account the billions of trees that have been cut down. I have been to Illinois where land with such rich soil has been virtually striped of trees so the farmers could plant two more rows of corn or soy, among other places for other reasons. Perhaps those trees slowed some wind down at some point so if the wind turbines slow it down... so what "That" is the way it was meant to be. Why are people worried about the disturbance of the wind?

Nobody sane is suggesting that we replace all our energy generation with wind power. Instead most scientists and energy experts I've been reading have said we are going to have to use a number of different energy sources.

Wind currents on the ground account for a minutia of energies used in all processes of weather. The presence of wind mills will not affect the heat radiated from the ground due to solar insolation, so it's not like convective processes (storms) are affected. Oceananically, the presence of even millions of wind mills would have an unmeasurable effect on "currents" and would have no effect no our lives on Earth. What will have effect is the continued emittance of green house gases into our atmosphere from coal burning and oil consumption. This "report" seems like something sponsored by Exxon.

Consider the butterfly effect. Energy removed by wind turbines will not go into thunderstorms, etc. I have suggested this to meteorologists for quite some time. As humans, it is not our position to try to control what God has initiated, but to adjust. As the cycles change, we must change. Take the blooming politics out of scientific decisions and quit the stupid hype of pushing uncertain theory as fact to fit political agendas. Most of the world and American population is ignorant in scientific matters, but they sure can be mislead by lies and fast talking politicians with teleprompters. It is basic physics.
