In a recent, thought-provoking article, Dr. Nina Pierpont writes:

As an ecologist, I’ve known about global warming since the 1970’s, especially in the work of certain marine scientists who began studying and modeling global carbon cycling forty years ago. The earth’s fossil record makes it clear that the earth has cycled back and forth between warmer epochs and colder throughout its history. At certain times the earth has been tropical to the poles.

There is no doubt that we are in a significant warming stage and that the human role in this is
critical, by releasing to the atmosphere enormous amounts of carbon locked up by trees and plants eons ago into oil and coal. Not only the burning of fossil fuels, but the destruction of forests also disturbs the carbon balance, on the other side. Forests are carbon “sinks,” reabsorbing carbon from the atmosphere and locking it up again into wood and leaves, cellulose and lignin. The energy in wood is the sunlight of past summers, but the substance is carbon from the air.

Global warming means not only more marked heat waves and melting glaciers and ice caps, but also increased variation in the weather. There is more energy in the atmosphere and hydrosphere not only for high temperatures, but also for more air movement, more wind, more storms, and greater swings between warm and cold, as air masses replace each other quickly and vigorously.

But wind generation is not the solution, even in a gustier world.
