President Obama’s Remarks at U.N. Climate Change Summit

John F. Kennedy once observed that "Our problems are man-made, therefore they may be solved by man." It is true that for too many years, mankind has been slow to respond or even recognize the magnitude of the climate threat. It is true of my own country, as well. We recognize that. But this is a new day. It is a new era. And I am proud to say that the United States has done more to promote clean energy and reduce carbon pollution in the last eight months than at any other time in our history.
