I find this interesting and will probably want to read the full article when it's released (it's dated for March 22nd, and today is the 20th).  I think it's important to note that they aren't denying Global 'warming', nor do I.  I'm just tired of the unfounded claims that implicate us as the cause by conjecture, not by actual evidence.  I find it interesting that this article is from NewScientist and can't help but be curious about why now a change in story?

If you don't know, my point has always been not in denying that there are drastic changes in climate, but that rather than think it's something we caused and can somehow fix, we need to worry about predicting it to be better prepared to survive it.  Trust me, when it's towards the end of March and temperatures around here are still below freezing at night, you can't convince me that we're warming, but you could convince me that temperatures are fluctuating more than they have been.  What you've never been able to convince me of is that the cause is human made carbon dioxide, when I know that more of that was released by Mt. St. Helens erupting than in the entire industrial revolution.  I'll need a better reason, thanks.

Rising temperatures bring their own CO₂

CLIMATE sceptics are right. Temperature increases do precede rises in atmospheric carbon dioxide - the opposite of what you would expect if changes in CO₂ levels were really driving climate change. That's the verdict of leading atmospheric modeller Peter Cox, a climate expert at the University of Exeter, UK. Yet far from dismissing the threat of global warming, Cox says this means things are worse than we thought. Events in the Little Ice Age, 400 years ago, prove the point, he says.

One of the most important pieces of evidence linking climate change to greenhouse gas emissions is that for tens of thousands of years, temperature changes have been in lockstep with atmospheric levels of carbon dioxide. But sceptics keep pointing out that temperature changes seem to come first.
