Political leaders will only undertake bold climate initiatives if they know the American people want it.

Wind and solar power, energy efficient buildings, cars that go farther on a tank of gas, and other solutions can fight climate change. I know America can get on a more sustainable path - we just have to raise our voices and demand it.

At least 3,527 U.S. monthly records for heat, rain, and snow were broken in 2012. We can't let this continue unchecked, and we don't have to.
