Their credentials and experience qualify them to me, and I'm fairly certain they were referred to in this way. And no, that was not a topic. I don't think its fair to attribute a single piece of literature, so broadly, to everyone in the climate change camp. That's the thing about science...it's always wrong...until it's right. One thing that may surprise the climate change deniers, is that the common consensus among these scientists, is that reducing carbon emissions will do nothing to what's already in motion. Much of the point of this is that they are saying planning at this point is far more important than mitigation. One other point they made, was that the effects of these changes are not yet evident across North America and Europe, but that doesn't mean they aren't happening. I was sincere when I said you should watch and then I'd be interested in hearing your opinion. It's a worthy presentation.
