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.

Climate change has the potential to affect everything we care about - whether it is the health of our families, the stability of our communities, or the fate of the wild animals.

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.

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.

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.
