An Inconvenient Fact That Undercuts Global Warming
Recently, I read Bill Bryson’s “A Short History Of Nearly Everything,” which is a book on scientific basics. Now keep in mind that Bryson’s book is no conservative tome. To prove that, he even got a favorable review from the New York Times Book Review, “Destined to become a modern classic of science writing.”
However, one fact in particular from his book greatly undercuts the idea that mankind is warming the earth.
“For most of its history until fairly recent times, the general pattern was for earth to be hot with no permanent ice anywhere.” — P.427
Now, if for most of earth’s history, there was no permanent ice, does that not suggest that our climate today is significantly cooler than it has been for most of mankind’s history?
Here’s another excerpt that confirms something skeptics of manmade global warming have pointed out again and again:
“For a long time it was thought that we moved into and out of ice ages gradually, over hundreds of thousands of years, but we now know that has not been the case. Thanks to the ice cores from Greenland we have a detailed record of climate for something over a hundred thousand years, and what is found there is not comforting. It shows that for most of its recent history Earth has been nothing like the stable and tranquil place that civilization has known, but rather has lurched violently between periods of warmth and brutal chill.
Toward the end of the last big glaciation, some twelve thousand years ago, Earth began to warm, and quite rapidly, but then abruptly plunged into bitter cold for a thousand years or so in an event known to science as the Younger Dryas.” — P.430
Point being that earth’s temperature has been changing, rather significantly, for a long, long, long time before man ever came on the scene and although there are plenty of theories, we don’t truly know or understand what caused the other worldwide climate shifts. Since that’s the case, how can we possibly state, as if it were fact, that mankind can be warming the earth when our understanding of the climate is so incomplete that we don’t know why the earth was warming or cooling before mankind could have possibly had any impact?
