But here is the bottom line: we can embrace this accord, take a substantial step forward, and continue to refine it and build upon its foundation. We can do that, and everyone who is in this room will be a part of an historic endeavor – one that makes life better for our children and grandchildren.

Or we can again choose delay, falling back into the same divisions that have stood in the way of action for years. And we will be back having the same stale arguments month after month, year after year – all while the danger of climate change grows until it is irreversible.

There is no time to waste. America has made our choice. We have charted our course, we have made our commitments, and we will do what we say. Now, I believe that it’s time for the nations and people of the world to come together behind a common purpose.

We must choose action over inaction; the future over the past – with courage and faith, let us meet our responsibility to our people, and to the future of our planet. Thank you.
