But yes, it was worth it. He talked a bit about Kyoto, but not as a mechanism for enforcement. He described Kyoto as evidence that countries can agree to address a problem. $9.25, actually.

And does he whine a lot about the Kyoto Protocol? Kyoto was a measure without any bite. And I'd hate to waste time watching somebody yearn garbage. So, was it worth the $8.00 for a ticket?

Polar melting may raise sea level sooner than expected
