And stop he doesn't in an Oct. 10 NewsBusters post mocking an Associated Press article carrying the headline Experts: Global Warming Means More Antarctic Ice." Sheppard huffed that climate scientists (of which Sheppard is not) "this truly amazing concept that anthropogenic global warming can melt ice in one hemisphere while creating it in another," going on to sneer that this was "unbelievable."
If it's amazing, that's because it's supported by science -- something neither Sheppard nor the deniers he calls upon to back him up, Christopher Horner and Steve Goddard, want to admit.
As Media Matters points out, the AP article accurately explained that Antarctic sea ice growth is consistent with climate scientists' projections for a warming planet, even as Arctic ice decreases.
Media Matters also reminds us that Sheppard's fellow bamboozlers are suspect -- Horner works at the Competitive Enterprise Institute is funded in part by the oil and tobacco industries, and Goddard is a birther as well as a global warming denier.
