What a useless discussion. It can be summed up in 1 line:

"We don't know yet, we will have to look into it."

Now you've read that you can save yourself 70 minutes.

I'd actually rather listen to the discussion, if you don't mind. You really expected a resolution to such an issue in a 70-minute panel discussion? Such cynicism is weak.

We are going to need to pursue geo-engineerng. See:

I wonder if we can't all stop for just a single moment to remember that engineers, financed by profit-driven organizations, are the principal architects of the mess we find ourselves in today. To suggest we hand that same basic group the keys to the family car and suggest they help us fix the problem smacks of denial and self-interest.

Look, they created a program in the 70's-80's to remove the sulfur from the air, and now they are talking about putting it back. Nevermind the fact that 15 years is too short of a time to show a trend (in their own words). So they were trying to force AGW down our throats for 15 years and there's been no statistically significant warming over the last 15 years. It's much ado about nothing.

And heaven help us if we get any colder. Iowa has been getting colder for the last 3 years. #32 coldest winter, #2 coldest summer. This year #30 coldest winter. Not to mention snow in 49 states. It's not supposed to snow in Florida.

NEWS:
Methane Releases from Arctic Shelf May Be Much Larger and Faster Than Anticipated

NSF, National Science Foundation - March 4, 2010.

Research results, published in the March 5 edition of the journal Science, show that the permafrost under the East Siberian Arctic Shelf, long thought to be an impermeable barrier sealing in methane, is perforated and is starting to leak large amounts of methane into the atmosphere. Release of even a fraction of the methane stored in the shelf could trigger abrupt climate warming.

As Martin Heimann writes in Science:

Wetlands and permafrost soils, including the sub-sea permafrost under the Arctic Ocean, contain at least twice the amount of carbon that is currently in the atmosphere as carbon dioxide. Release of a sizable fraction of this carbon as carbon dioxide and/or methane would lead to warmer atmospheric temperatures, causing yet more methane to be released. It would thus create a positive feedback loop that amplifies global warming.
