Looks like ExxonMobil CEO Rex Tillerson dusted off Donald Rumsfeld's PR play-book in explaining Exxon's stance on global warming, here's the quote:

There's much we know and can agree on around the climate change issue, and there’s much that we just don’t believe we do know…and we want to have a debate about the things we know and understand, the things we know about that we don’t understand very well, and the things we don’t even know about around this very complex issue of climate science. So that will continue to be our position."

Thanks for clearing that up Mr. Tillerson.

Rep. Brad Miller (D-North Carolina), chair of the House Subcommittee on Science and Technology, fired off a strong letter (pdf) to ExxonMobil demanding that the oil giant hand over documents relating to all grants awarded so far in 2007 by recipient

Could this be the first step in a Congressional hearing similar to Rep. Henry Waxman's famous Big Tobacco Hearings?

Sure looks that way.

Despite ExxonMobil's denials, a report released today by Greenpeace's ExxonSecrets.org project, reveals that the largest oil company in the world continues to spend millions on a stealth public relations campaign aimed at discrediting global warming science.

According to the report, Exxon provided $2.1 million in 2006 to 41 "think" tanks and associations that actively sow doubt about the realities of climate change. Since 1998, ExxonMobil has spent a staggering $23 million on this climate disinformation.

Anyone celebrating ExxonMobil's recent announcement that it acknowledges the truth of climate change can stick the cork back in the bottle. While Exxon's vice president for public affairs, Kenneth Cohen cast climate cange as undeniable, ExMo CEO Rex Tillerson made it clear yesterday that the company is still happily clinging to doubt.

“My understanding is there’s not a clear 100 percent conclusion drawn,” Tillerson told an industry gathering in Houston. “Nobody can conclusively 100 percent know how this is going to play out. I think that’s important."
