It seems Bill needed help, as well:
“Gregory allowed the discussion to proceed despite some terse exchanges, but said he had to step in when Blackburn claimed that scientists lack sufficient evidence to say that carbon dioxide increases in the atmosphere have had a significant environmental impact.
“Well, hold on, I just have to interrupt you,” Gregory said. “I’m sorry, congresswoman, let me just interrupt you, because it’s not — you can pick out particular skeptics, but you can’t really say, can you, that the hundreds of scientists around the world who have looked at this have gotten together and conspired to manipulate data?”
The representative argued that “there is not consensus” that greenhouse gas emissions have had a major effect on global warming.
“But there is consensus,” Gregory responded. “Within the scientific community, there is consensus.”

I guess Billy Nye the Single Guy couldn’t hold his own in the debate...

And that's against a female politician, the least likely to know anything at all about science short of a female 3rd grade public school teacher! It's extremely rare for anyone pushing global warming to get as "scientific" as to actually use a measurement like ppm when describing carbon. Usually they just say "scientists all agree that we have global warming therefore vote Democrat". But no one at all is discussing how 1 molecule out 2500 is able to cook the other 2500. Then to try to bring into the discussion the concept of a self correcting system where warmer water actually increases plankton's consumption of carbon... NO that'll never happen. We just get pictures of polar bears, smoke stacks, melting ice, etc. No science ever!
