Looks like she's a bit worried?

Even Clinton is getting up-close with the rising thrust of the global warming talk around DC these days:

And now, thanks to former Vice President Al Gore, who has been a committed visionary on global warming for more than two decades, everyone can see those consequences for themselves at a local movie theater.

But this is not a time, I would argue, for handwringing or despair, despite the formidable challenges we confront. We can fix these problems together by changing to a clean energy future fueled by innovation and efficiency, and of course the alternative is pretty stark. If we don't change, our problems will only worsen.

Maybe it's just because she hasn't gotten it in a while, or maybe she's a bit worried that Al Gore's name has been mentioned a few too many times recently?
