Now, as the world's largest economy and as the world's second largest emitter, America bears our responsibility to address climate change, and we intend to meet that responsibility.
The United States stands at the pinnacle of world power. This is a solemn moment for the American democracy. For with primacy in power is joined an awe-inspiring accountability for the future.

And that's what I intend to reverse when I'm President of the United States of America.
