US Presidency
2015

And the best scientists in the world are all telling us that our activities are changing the climate, and if we don't act forcefully, we'll continue to see rising oceans, longer, hotter heat waves, dangerous droughts and floods, and massive disruptions that can trigger greater migration and conflict and hunger around the globe. The Pentagon says that climate change poses immediate risks to our national security. We should act like it. And that's why, over the past six years, we've done more than ever to combat climate change, from the way we produce energy to the way we use it. That's why we've set aside more public lands and waters than any administration in history. And that's why I will not let this Congress endanger the health of our children by turning back the clock on our efforts. I am determined to make sure that American leadership drives international action. In Beijing, we made a historic announcement: The United States will double the pace at which we cut carbon pollution.
