Daniel Yergin is to peak oil and limits to growth what Richard Lindzen, Anthony Watts, Christopher Monckton, the Heartland Institute and Exxon Mobil are to climate change. That is, Yergin's entire reason for being in the public eye is his rejection of the possible arrival of this calamity.
So of course it's perfectly logical that the Wall Street Journal, long a bastion of climate change denial, would give Yergin a stage on which to spew his unique brand of half-truths.
