Today over at the Huffington Post, California Senator Barbara Boxer contributes her third post to the locally based blog and news site -- this time in an effort of advocacy:

Today, the U.S. Senate begins debate on the Climate Security Act, a critical bill that will address the global warming crisis head-on. After many months of committee hearings and testimony, our bill has finally reached the Senate floor. It's a day we've been waiting for a long time.

The Climate Security Act would enact the world's most far-reaching program to fight global warming, instituting an economy-wide cap on emissions that would cut greenhouse gases below 1990 levels by 2020 and slash emissions by nearly 70% by 2050.

In addition to fighting global warming, our bill will provide cleaner air, greater energy efficiency, relief for consumers, and the alternative energy choices that American families deserve -- significantly reducing America's dependence on foreign oil. What's more, by acting wisely on global warming, America will regain much of the leadership and respect we have lost around the world these past seven years.

She warns that the "far-right" will fight and fight hard against this bill. And even though she believes this bill is not strong enough, it's critical to push this through now with strong amendments in the future. "This will be one of the toughest fights of our generation. Getting the strongest global warming bill possible passed through the Senate will send a strong message that we do not intend to stand idly by while scientists warn us again and again that our planet is in jeopardy," she writes further.

At the end of her post, she encourages readers to send an e-mail to their senator in support of the bill using this link.
