Why windmills won’t wash | Watts Up With That?: "The “global warming” that the Thanet wind-farm will forestall in its 20-year lifetime is 0.000002 Celsius, or two millionths of a degree, or 1/25,000 of the minimum global temperature change that modern methods can detect. The mitigation cost-effectiveness, per Celsius degree of warming forestalled, is £578 trillion ($954 trillion), or almost 6000 times the entire 296 years’-worth of UK peacetime and wartime national debt as it stood when Margaret Thatcher took office. That’s more than 1.7 million years’ British national debt, just to prevent 1 degree of warming.
Making IPeCaC’s predicted 3.4 C° of 21st-century warming go away, if all measures were as cost-ineffective as Thanet, would take more than half of the world’s gross domestic product this century, at a cost of more than £280,000 ($463,000) from every man, woman and child on the planet."
RTWT as they say. You never thought math could be so entertaining... and scary.
