THE WAY THINGS USED TO BE IN YOUR GREAT-GRANDPARENTS' IMAGINATION:

What's so hot about fickle science? (MARK STEYN, 2/04/07, Chicago Sun-Times)

The silliest argument is the anecdotal one: "You only have to look outside your window to see that climate change is happening." Outside my window in northern New England last week, it was minus 20 Fahrenheit. Very cold. Must be the old climate change kicking in, right? After all, December was very mild. Which was itself a sign of climate change. A few years ago, the little old lady who served as my town's historian for many decades combed over the farmers' diaries from two centuries ago that various neighbors had donated to her: From the daily records of 15 Januarys, she concluded that three were what we'd now regard as classic New Hampshire winters, ideal for lumbering or winter sports; eight had January thaws, and four had no snow at all. This was in the pre-industrial 18th century.

Today, faced with eight thaws and four entirely snowless Januarys, we'd all be running around shrieking that the great Gaia is displeased. Wake up and smell the CO2, people! We need to toss another virgin into the volcano. A virgin SUV, that is. Brand-new model, straight off the assembly line, cupholders never been used. And as the upholstery howls in agony, we natives will stand around chanting along with High Priestess Natalie Cole's classic recording: ''Unsustainable, that's what you are.''

As we say in the north country, if you don't like the weather, wait five minutes. And if you don't like the global weather, wait three decades. For the last century or so, the planet has gone through very teensy-weensy warming trends followed by very teensy-weensy cooling trends followed by very teensy-weensy warming trends, every 30 years or so. And, even when we're in a pattern of "global warming" or "global cooling," the phenomenon is not universally observed -- i.e., it's not "global," or even very local. In the Antarctic, the small Palmer peninsula has got a little warmer but the main continent is colder. Up north, the western Arctic's a little warmer but the eastern Arctic's colder. So, if you're an eastern polar bear, you're in clover -- metaphorically, I hasten to add. If you're a western polar bear, you'll be in clover literally in a year or two, according to Al Gore.

And, if you really don't like the global weather, wait half-a-millennium. A thousand years ago, the Arctic was warmer than it is now. Circa 982, Erik the Red and a bunch of other Vikings landed in Greenland and thought, "Wow! This land really is green! Who knew?" So they started farming it, and were living it up for a couple of centuries. Then the Little Ice Age showed up, and they all died. A terrible warning to us all about "unsustainable development": If a few hundred Vikings doing a little light hunter-gathering can totally unbalance the environment, imagine the havoc John Edwards' new house must be wreaking.

After thorough investigation I can likewise report that there is no way it could have been uphill to school both ways when our grandmother was little.
