"It is long overdue to make the hard choices -- about alternative energy and clean coal, conservation and fuel efficiency -- that will free our future from the dominance of big oil and yesterday's fossil fuels, a dominance that in the era of global climate change threatens the future itself. Here's the bottom line: within the next decade, if we don't deal with global warming, our children and grandchildren will have to deal with global catastrophe. We cannot postpone the reckoning until the day after tomorrow. If you offend no one, you change nothing. The world is changing and now the reckoning is real. The House and the Senate need to act on global climate change, and we need to heed Vice President Gore's warnings."
