More support from the Republican party for action on climate change, as John McCain responds to a question from Hardball's Chris Matthews on MSNBC about where he differs with Bush. Here's what McCain had to say:

So what's an area of disagreement? Climate change. Climate change. I believe that climate change is real. I think we have to act...

(APPLAUSE)

Absolutely right Senator. He continued on to try to convince those who still deny the reality of the climate crisis to come on board anyway:

I would just like to put the question this way to my fellow Americans. Suppose that we are wrong and there's no such thing as climate change but we go ahead and adopt green technologies and we reduce greenhouse gas emissions? All we've done is give our kids a cleaner planet, OK? But suppose...

(APPLAUSE)

Suppose we are right and do nothing. Suppose we just continue this endless debate and continue the increase of greenhouse gas emissions, and we hand these wonderful Americans a damaged planet? I think the answer to that is pretty obvious.

An interesting call to action from John McCain on climate, to be sure. Citing this as a departure from Bush's policies however, may soon prove problematic as Bush has also indicated recently that the Administration will push for legislation regulating greenhouse gases.

Given that all three frontrunner candidates for the Presidency are on board for fighting global warming, the November election, no matter the outcome, will almost definitely spell progress for agreeing on a successor to the Kyoto Protocol.
