Global Warming Proponent Admits: The Facts Don't Support the Contention

Brit Hume at Fox News features a piece on a former apostle of global warming, David Evans, is now a heretic to the religion of anthropogenic global warming.

How sad. High Priest Al Gore is losing converts left and right, these days. Blind faith just ain't what it used to be.

Here's what the Fox News piece says:

Evans writes in The Australian newspaper that if global warming was caused by C02, scientists would have found hot spots about six miles up in the earth's atmosphere over the Tropics. Evans describes those hot spots as the signature of the greenhouse effect. He says scientists have been trying to locate them for years using thermometers attached to weather balloons.

But he says years of research "show no hot spot — whatsoever" adding that "an increased greenhouse effect is not the cause of global warming."

One might consider Evans a part of the priesthood himself, having built models for the Australian Greenhouse Office to measure Australia's compliance with Kyoto.

He says in the piece he wrote at The Australian that in 1999 the evidence "seemed pretty good," but...
But since 1999 new evidence has seriously weakened the case that carbon emissions are the main cause of global warming, and by 2007 the evidence was pretty conclusive that carbon played only a minor role and was not the main cause of the recent global warming. As Lord Keynes famously said, "When the facts change, I change my mind. What do you do, sir?"

If you're Al Gore, you keep riding the same dead horse until he's ground beef, or ground horse at least. Or a stinking carcass, which is where the theory of anthropogenic global warming is headed fast.

Evans points out several of "the most basic salient facts":
1. The greenhouse signature is missing. We have been looking and measuring for years, and cannot find it.

2. There is no evidence to support the idea that carbon emissions cause significant global warming. None.

3. The satellites that measure the world's temperature all say that the warming trend ended in 2001, and that the temperature has dropped about 0.6C in the past year (to the temperature of 1980).

4. The new ice cores show that in the past six global warmings over the past half a million years, the temperature rises occurred on average 800 years before the accompanying rise in atmospheric carbon. Which says something important about which was cause and which was effect.

Evans goes into some detail on each of these facts, so I'd encourage you to read the entire article.

Evans obviously hasn't sold out his liberal credentials, since he makes it clear here that he doesn't want the Labor government to shooting itself into the foot and getting booted out of office for a long time:
The Labor Government is about to deliberately wreck the economy in order to reduce carbon emissions. If the reasons later turn out to be bogus, the electorate is not going to re-elect a Labor government for a long time.

If Democrats in the United States were smart, they'd pay attention to this (but hopefully the won't.) If some of the Republicans weren't such dumb sheep, they'd have already figured this out; hopefully it's not too late.

I suppose Gore will throw Evans out of the Church of Global Warming now. But Evans is certainly welcome at places where thinkers are present.
