WUWT: Just Enough Information to Mislead

WUWT: Just Enough Information to Mislead
on

You can’t beat Anthony Watts‘ team at WUWT (either Watts Up With That or We Use Wishful Thinking, it’s hard to tell) for the delicate selection and presentation of “evidence” to argue that climate isn’t changing.

Here, for example, is a post that trumpets a Nature article on the climate effects of the Atlantic Multidecadal Oscillation. WUWT also credits the reputable German publication Der Spiegel as an intermediate source for this information and then posts the graph (left) as easy visual proof that what’s happening in climate today is all part of a normal up and down.

But have a close look at that graph. First, it doesn’t come from the Nature paper or from Der Spiegel. It was cobbled together on a denier site run by an engineer named Alan Cheetham.  Second, the yellow lines showing a downward resumption on the right side are based on – well, actually, on no data points whatever. While Cheetham may have a crystal ball, a touching optimism or a cavalier disregard for objective presentation, he has no evidence at all.

But he has a fan in Anthony Watts. Watt does that tell you?

I noticed this while reading another post in which Watts insults John Cook from the excellent blog, Skeptical Science (there is a link, incorrectly attributing the material above to New Scientist). Watt’s quotes this passage from Sourcewatch:

John Cook, on his website Skeptical Science, states that “the usual suspects in natural climate change – solar variations, volcanoes, Milankovitch cycles – are all conspicuous in their absence over the past three decades of warming.

… and then he goes on to provide three links (1, 2, 3) that purport counter Cook’s position.

Well, the whole post is dumb. Cook isn’t saying that there were NO ocean oscillations, volcano effects or Milankovitch cycles in the last 30 years. It seems clear that he was saying that global temperatures have been rising regardless that these influences have been absent, irrelevant or (in the case of volcanoes) acting to counteract warming.

Beyond being obtuse, Watts also has a little hissy about Cook using the “ugly word ‘denier’” in reference to people who, uh, manipulate or misrepresent scientific information to suggest that climate change is not happening, is natural or is nothing to worry about.

Watts the deal, Tony? Got a guilty conscience?
