More on Watt’s Game-Changer

Via Peter Sinclair and ABC Australia:

MARK COLVIN: They’re saying that it is the first indication that the IPCC recognises something called solar forcing.

STEVE SHERWOOD: It’s not the first time it recognises it. What it shows is that we looked at this. We look at everything. The IPCC has a very comprehensive process where we try to look at all the influences on climate and so we looked at this one.

And there have been a couple of papers suggesting that solar forcing affects climate through cosmic ray/cloud interactions, but most of the literature on this shows that that doesn’t actually work.

MARK COLVIN: So you’re saying that you’ve managed to basically eliminate this idea that sunspots or whatever are more responsible for global warming than human activity.

STEVE SHERWOOD: Based on the peer-reviewed literature that’s available now, that looks extremely unlikely.

MARK COLVIN: So what have these people done? Is this just a case of cherry-picking a sentence?

STEVE SHERWOOD: Yeah, it’s a pretty severe case of that, because even the sentence doesn’t say what they say and certainly if you look at the context, we’re really saying the opposite.
