So... the argument is that we need a millions years+ of data to prove global warming is man made, even if humanity can only survive the global warming pace for another 100-200 years?

Don't think I've ever said this on the forums... but I'm actually going to agree with Jarvan's earlier responses. But again point out that this is why we can't get to Jarvan's concerns, because everyone is so hung up on the first part to discuss the second part rationally.
