Al Gore weighs in on the G8

This pretty much tells it all:

MILAN (Reuters) - Former U.S. Vice President Al Gore denounced a deal by world leaders on curbing greenhouse gases as "a disgrace disguised as an achievement," saying on Thursday the agreement struck last week was insufficient.

… "It was a disgrace disguised as an achievement," Gore said at an event in Milan, where he praised Merkel for her efforts.

"The eight most powerful nations gathered and were unable to do anything except to say 'We had good conversations and we agreed that we will have more conversations, and we will even have conversations about the possibility of doing something in the future on a voluntary basis perhaps."'
