Global Cooling Is Making A Comeback!

Reader MikeAT hooked me up with the following article:

Our finding of a direct correlation between variations in the brightness of the sun and earthly climate indicators (called "proxies") is not unique. Hundreds of other studies, using proxies from tree rings in Russia's Kola Peninsula to water levels of the Nile, show exactly the same thing: The sun appears to drive climate change...

Solar scientists predict that, by 2020, the sun will be starting into its weakest Schwabe solar cycle of the past two centuries, likely leading to unusually cool conditions on Earth. Beginning to plan for adaptation to such a cool period, one which may continue well beyond one 11-year cycle, as did the Little Ice Age, should be a priority for governments. It is global cooling, not warming, that is the major climate threat to the world, especially Canada. As a country at the northern limit to agriculture in the world, it would take very little cooling to destroy much of our food crops, while a warming would only require that we adopt farming techniques practiced to the south of us.

So, perhaps cycles in the sun have a significantly greater impact on earth's temperature than does man? Wow, I never would have thought that.

Here's another tidbit, though, for the "settled science" crowd:

In some fields the science is indeed "settled." For example, plate tectonics, once highly controversial, is now so well-established that we rarely see papers on the subject at all. But the science of global climate change is still in its infancy, with many thousands of papers published every year. In a 2003 poll conducted by German environmental researchers Dennis Bray and Hans von Storch, two-thirds of more than 530 climate scientists from 27 countries surveyed did not believe that "the current state of scientific knowledge is developed well enough to allow for a reasonable assessment of the effects of greenhouse gases." About half of those polled stated that the science of climate change was not sufficiently settled to pass the issue over to policymakers at all.

So, just who is this yayhoo who doesn't know what he's talking about?

Damned Darren, not one comments on this post I sent you...that bums me out. Where is Anonymous screeching about hate speech and how we have to get into a sub-sub-sub-sub-mini-compact car (no doubt while he’s getting into a Expedition)?

I am depressed!
