Warren Buffett’s vice chairman, Charlie Munger , told a small meeting of investors that former Vice President Al Gore is “not very smart” and “an idiot” but was still able to make “$3 or $400 million in your business” by “obsessing” about “global warming.”

“Al Gore has hundreds of millions dollars in your profession. And he’s an idiot. It’s an interesting story. And a true one,” Munger told investors. According to CNBC on June 23: “Though the comments were made more than four months ago, they went largely unnoticed and have not been widely reported on elsewhere.”

“Al Gore has come into you fellas business, Munger said. “He has made $3 or $400 million in your business. And he’s not very smart. He smoked a lot of pot as he coaxed through Harvard with a gentleman’s C. But he had one obsessive idea that global warming was a terrible thing and he would protect the world from it,” he explained. [Note: Gentleman’s C is defined by Urban Dictionary as “A grade given to a student (traditionally with wealthy parents) instead of a failing grade.”]

According to CNBC:

“Munger is one of the most celebrated investors in the world and was an essential partner in Buffett‘s success. Before becoming vice chairman of Berkshire Hathaway, the billionaire had quite the track record himself. From 1962 to 1975 Munger’s investment partnership generated 20 percent annual returns versus the S&P 500‘s 5 percent.”

Watch:

“So his idea when he went into investment counseling is he was not going to put any CO2 in the air,” Munger explained to the investors noting that Gore’s simple strategy of buying only service company stocks enabled the former Vice President to become very rich.

Munger explained: “So he found some partner to go into investment counseling with and says we’re not going to have any (carbon dioxide). But this partner is a value investor and a good one. So what they did is, is Gore hired staff to find people who didn’t put CO2 in the air. Of course that put him into services. Microsoft and all these service companies were just ideally located. And this value investor picked the best service companies. So all of a sudden the clients are making hundreds of millions of dollars and they are paying part of it to Al Gore. Al Gore has hundreds of millions dollars in your profession. And he’s an idiot. It’s an interesting story. And a true one.”
