If I had ten billion dollars to spend on combatting climate change, I'm honestly not sure what I'd do with it, and I rather think that if you are then you haven't really looked into the question.

@joeld @solar_chase it still requires a regulatory change, which is slightly out of scope of the question — under current law, you can’t lease a coal reserve (at least in the US) without planning to exploit it
