An Inconvenienter Truth
Putting Global Warming in World-Historical Context.
A meteorologist with the oh-so-excellent name of Joe Bastardi, puts things into perspective.
Our knowledge of the past should serve as a foundation for actions in the present. While not dismissing those who are concerned about global warming, I am disturbed that they often base their conclusions on data that, in the context of time, are only a grain of sand on the beach. They cite temperature changes from the last 10, 50, or 100 years, ignoring the fact that climate history and cycles didn’t start 10 years or even 10 centuries ago.
Nothing that is happening today is new or different. I have yet to have a global warming "true believer" tell me why over the past hundreds and thousands of years, before any significant or even detectable human influence, there were periods where carbon dioxide and temperature levels were well above those of recent experience. There are also places in our northern plains that have been covered with glaciers at one time and tropical rain forest at others, all without man’s influence. There is no reason to think that this can’t happen again no matter what we do. Anyone with a true understanding of climate history knows that the relatively small changes experienced over the last 100 years could easily be "natural."
