Hi everyone.

The last time Al Gore came to Capitol Hill--six years ago--he was there to certify the electoral college results that made George Bush president.

But today it was a triumphant return, this time as a private citizen, to declare that the world faces a "planetary emergency" over climate change. And now, a lot of his skeptics agree that Gore makes a powerful point.

The scientific consensus is clear, and Gore urged Congress to listen to scientists, not special interests. He pushed for an immediate freeze on greenhouse gases, as well as cleaner power plants, more efficient cars, and stronger conservation efforts.

Gore said "a few years from now...the kinds of proposals we're talking about today are going to seem so small compared to the scale of the challenge."

Here's hoping Congress puts partisanship aside, and comes together to act boldly on global warming.

That's a page from my notebook.
