I really don't understand the physics behind statements such as these. If you really could place a uniform thermal blanket of gas around the world, and it started warming, then why would there be more storms? Would you have less storms in a cooling cycle? Or a static phase? I know that on the US east coast there have been hurricane cycles that are independent of anything else. What drives them?
The world has always been in warming cycles, cooling cycles, peaks and troughs. I must come to the conclusion that there is more money available whenever anybody plays the 'guilt card', and so it gets played for everything.
Actually, I think that ocean currents are really underplayed here, so this big push for oceanic mega-bucks might be more than a mere money grab.
