Whether the debate is over or not is a personal question. Whether you BELIEVE that it's all bullshit, or BELIEVE that the planet is warming and human industry is a contributing factor, if you BELIEVE, the debate is over for you.
The only folks for whom the debate is
not over are the undecideds.

Whether or not Jon Stewart has any credibility as a 'journalist' is moot - the people who voted for the congressmen featured in the clips in the O/P video should be embarrassed. At best, those committee members are playing stupid to advance an agenda, at worse, they really are
that stupid.
Whether or not the planet is warming and human industry is a contributing factor is also moot, ass-u-me-ing one is not stupid enough to believe that pollution in the air is something we should just have to live (and die) with.

Did we learn NOTHING from the successful clean-up imposed on industry in the 1970's?
