House Republican leaders voted more than 300 times to undermine environmental safeguards since 2011, but almost none of these measures became law because Americans pushed back.

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

Write to your newspaper. Call your Member of Congress. Email President Obama. Speak out for a cleaner, more stable future for all of us.

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

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.

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.

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.

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.

Climate change deniers would have us believe that oil, gas, and coal are the only ways to power a modern, industrialized society. They are wrong, and the proof is all around us.
