In the News (from Forbes): “’Large windfarms can increase local night time temperatures by fanning warmer air onto the ground, new research has revealed. The study used satellite data to show that the building of huge wind farms in west Texas over the last decade has warmed the nights by up to 0.72C.’
“The basic effect is that given that the ground at night is generally cooler than the atmosphere, thus the air near the ground is cooler than the air higher up. Turning blades of the turbines mix up this air, cool with warmer, and thus lower the temperature of the higher up air.
“The effect is quite large too, that 0.72 of a degree is not far off the 0.8 of a degree which is said to be the total amount of anthropogenic global warming so far.
“However, amusing as this is, being able to point to one of the proposed solutions for climate change as being a cause of it, it’s not actually anything that affects the larger picture.
“We’re not changing the amount of heat that is disappearing off into space with this and thus not changing the basic energy balance of the planet. We’re just moving it around a bit, that’s all.
“As with the earlier paper that showed that offshore windmills will lower the air temperature around them by 1 degree or so: I assume from that same mixing increasing the evaporation rate of the sea water.”
My Comment: If we think that we can win somewhere without losing elsewhere, we deceive ourselves by forgetting about the unity of nature and its laws of a closed system.
We cannot fool nature, no matter what; in order to become harmonious with nature, we will have to change egoism as the root and cause of the created situation.
