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.

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

Will we confront climate change in time or will we let fossil fuel companies determine our fate? This is a fight we can't afford to lose, and that's what keeps me moving forward.

I think every single American believes they have a right to clean air and clean water.

Ordinary people have an extremely important role to play in fighting climate change. Not only can you make your home more energy efficient, drive less, and eat more local food - you can also tell your leaders to take climate action.

Americans have made it clear we want to build a more sustainable future. I am excited to harness that energy and see what we can create together.
