But we've heard that before. We must make some noise to ensure that Obama keeps that promise.
To that end, on Sunday, February 17, thousands of Americans concerned about the future of this planet will converge on the National Mall in Washington, DC, for what organizers are calling the "largest climate rally in U.S. history".
If you can get to DC on Sunday, please stand with us as we urge President Obama to put his words into action.
Even if you can't get to DC, there are ways you can participate.
