By the way - did he explain this set of facts?

No?
Figures.
The first thing that strikes me about that graph is that it doesn't include actual data (the black line) after 2001, only what the author says is a "Cochrane Orcutt" fit to said data. Nor does he stipulate what parameters he inserted into the formula, nor why he doesn't use simple regression (which, as we know, shows a warming trend this century).
I'm thinking that the parameters are very carefuly chosen to produce a downward trend, given that 2005 was the warmest (or equal warmest) on record, and 2007 about the third warmest, despite a La Nina towards the end. Was 2001 as a starting point also very carefully chosen?
The legend refers to an "IPCC short-term projection", but is there such a thing? I'm not aware of it. Perhaps he just means the first few years of the TAR projection, which is hardly meant to be relevant over such a short term.
Which brings up the point that this is yet another GWSceptic piece focusing on the post-98 period, one which they feel comfortable with because (with judicious choice of statistical methods and parameters) it can be presented as not exhibiting a warming trend. In the case of a true carpet-chewer (such as Melanie Philips) temperatures can be presented as "dropping like a stone".
What are you guys going to be clinging to in two-to-seven years time? Solar Cycle 24 and its up-phase? That would be unfair on Solar Cycle 23's down-phase, whcih hardly ever gets mentioned, but nobody ever said life would be fair. So I do expect to see that. Al Gore? For sure (barring accident; he's relatively young, with an excellent health-plan and no history of substance abuse). A 60-80 year cycle? That's rapidly running out of legs. Singer's 1000-2000 year cycle, on the other hand, is a long-term fallback, so I guess that'll come up.
(And the burying of heads in bristlecone pines will never get old for some people.)
Or perhaps something entirely new. You guys are nothing if not inventive. Who saw the cosmic ray thing coming back in '98? Not me. I didn't see the '98 El Nino coming either, but I do see one coming in the next two-to-seven years, and that's going to present you guys with quite a challenge.
