"On the global-warming front, the opening of the U.N. General Assembly this week coincided with a major meeting on climate change, attended by more than 80 world leaders. As U.N. Secretary-General Ban Ki-moon kicked off the meeting, he said: “We hold the future in our hands. Together we must ensure that our grandchildren will not have to ask why we have failed to do the right things and left them to suffer the consequences. So let us send a clear and collective signal to people everywhere. Today, let the world know that you are ready to shoulder this responsibility and that you will address this challenge head-on.”"
