Global Climate Change?

We have been hearing a lot lately about global climate change. Actually we were hearing a lot about global warming. But since comedians kept making jokes about Al Gore giving global warming warning speaches while it was snowing outside the environmentalists have started calling it global climate change instead. I have more to say about this topic, but still have several things left to get finished up for my middle school volleyball team before next thursday, so I'll write more later. In the meantime here is an article you should read.

The Faithful Heretic
is about 86 year old Reid A. Bryson the father of the science of modern climatology.

Here is a brief excerpt:

Almost 40 years ago, Bryson stood before the American Association for the Advancement of Science and presented a paper saying human activity could alter climate.

“I was laughed off the platform for saying that,” he told Wisconsin Energy Cooperative News.

In the 1960s, Bryson’s idea was widely considered a radical proposition. But nowadays things have turned almost in the opposite direction: Hardly a day passes without some authority figure claiming that whatever the climate happens to be doing, human activity must be part of the explanation. And once again, Bryson is challenging the conventional wisdom.

“Climate’s always been changing and it’s been changing rapidly at various times, and so something was making it change in the past,” he told us in an interview this past winter. “Before there were enough people to make any difference at all, two million years ago, nobody was changing the climate, yet the climate was changing, okay?”

“All this argument is the temperature going up or not, it’s absurd,” Bryson continues. “Of course it’s going up. It has gone up since the early 1800s, before the Industrial Revolution, because we’re coming out of the Little Ice Age, not because we’re putting more carbon dioxide into the air.”

Little Ice Age? That’s what chased the Vikings out of Greenland after they’d farmed there for a few hundred years during the Mediaeval Warm Period, an earlier run of a few centuries when the planet was very likely warmer than it is now, without any help from industrial activity in making it that way.
