Crab and Flying Lawyer,
This dialog is a good one, but it has the aura of the beginnings of a nightmare for those of us who have truly read several of the more erudite scientific papers on the subject (remember that of the all the papers written by climate scientists, none disagree).
While the story has been stolen by those who falsely claim that there is "scientific disagreement" and by those who say that "only computer models" predict the problem, the inexorable warming has started, with unprecedented CO2 levels, worldwide temperatures and vast worldwide melting evident. Martin Frobisher would leap for joy in the new ability to sail across the Arctic Ocean!
Crab and Lawyer, I truly wonder what more is needed to convince us that action is needed?
