A U.S. carbon-capping bill aimed at curbing climate change died on Friday in the Senate but its supporters looked to the next president to enact a global warming law as early as 2009.The bill aimed to cut total U.S. global warming emissions by 66 percent by 2050. Opponents said it would cost jobs and raise fuel prices in an already pinched American economy. Far from being discouraged, Sen. Joe Lieberman said international observers would be gratified that the measure got support from a majority in the Senate, including presumptive presidential nominees John McCain and Barack Obama.
