I had wondered, if the present warming rate goes on indefinitely, how long is it before we go back to the levels that produced 3 foot bugs and such in the carboniferous or whatever it was? Because I'd really worry about going past that. Massive change to human civilization and the ecosystem is one thing; Venus is another. I finally looked it up and a rough estimate appears to be 300 years. So I guess 446 years to melt all the ice sounds generally consistent.

"I had wondered, if the present warming rate goes on indefinitely" Why would it? There are plenty of mechanisms that prevent that. Don't worry too much. The earth doesn't care about a few degrees. Humans might though, at least 99% of the population won't be able to survive if the earth heats a few more degrees. The question is if anyone will care though. We advance pretty quickly in terms of technology. It's not a far stretch to imagine that humans simply convert into a philosophy of "earth as the first space colony". That would actually make a lot of sense too. If we can't manage to colonize earth when it goes to shit, we don't even need to try with other planets. This could become the catalyst for human space travel. There is a positive in everything :D.
