Speaking of facts–I mean whether they matter on the op-ed page–pointing out that someone else has distorted or minimized or ignored inconvenient facts seems to me to be one of the hallmarks of an op-ed since it's one of the key moves in any critical argument.  Perhaps for that reason alone op-ed editors ought to be ever more vigilant for claims such as the following from George Will:

Regarding McCain's "central facts," the U.N.'s World Meteorological Organization, which helped establish the Intergovernmental Panel on Climate Change — co-winner, with Al Gore, of the Nobel Peace Prize — says global temperatures have not risen in a decade. So Congress might be arriving late at the save-the-planet party. Better late than never? No. When government, ever eager to expand its grip on the governed and their wealth, manufactures hysteria as an excuse for doing so, then: better never.  

Sounds like the IPCC says the globe isn't warming.  But:

Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice and rising global average sea level.

That's the IPCC report of 2007.  Will seems to think temperature and climate are the same thing.  They're obviously not.  Can't someone at the Post tell him? 

The rest of his piece seemed a perfectly fine excursus on why some proposed measure to address global warming (cap and trade of carbon emissions) is a bad idea.  It might be.  But not because global warming is a communist hoax.  What communist hoax would use a capitalist system–trading and markets–to undermine capitalism?  But maybe that's just what the communists want us to think.
