I've thought about this, but I think there's a serious question as to whether humans can even muster an effort on the scale that would be required to harvest and prevent release into the atmosphere. Take ocean clathrates, for example. At a certain point, the ocean may become warm enough to destabilize them. What do we do in that case? Put up collection tents over the ocean that are millions of square kilometers large? The problem just doesn't seem tractable. But who knows? I'm certainly not the sort of engineer that is qualified to answer these questions.
