He's already made $100 million from it. (Not that that would color his views.) So he's already at least quaintly, mildly pleasantly rich from it. Cheers, James Arthur

He means methane hydrates, stores of methane frozen underseas (that might be freed if temperatures rise enough). Note that by saying "It isn't a high probability scenario", he's saying it's something but might happen, but isn't certain. IOW, "We don't understand, and we don't know. We're guessing."

Since orbitals are similar to the last glaciation, one could argue that glaciation is a more likely risk. So we should be trying to prevent glaciation rather than warming. -- - When the Rapture comes, can I have your car? When global warming comes, can I have your coat?
