But he’s not willing to let the rest of us know what this vital information is:

So we called Barnes and asked him what he was referring to.

At first, he cited the fact that it’s been cold lately.

Perhaps sensing this was less than convincing, Barnes then asserted that there had been a “cooling spell” in recent years. “Haven’t you noticed?” he asked.

Asked for firmer evidence of such cooling, Barnes demurred, telling TPMmuckraker he was too busy to track it down.

We pressed Barnes again: surely he could tell us where he had found this vital new information, which could upend the current debate over how to address global warming.

In response, Barnes said only that he knew where he had found it, but would not tell us, apparently as a matter of principle. “I’m not going to do your research for you,” he eventually said, before hurriedly ending the call.

What an idiot. Actually, the word is liar.
