By JOHN M. BRODER Published: November 18, 2008 President-elect Barack Obama, in strongly-worded remarks to a gathering of governors and foreign officials on Tuesday, said he had no intention of softening or delaying his aggressive targets for reducing emissions that cause the warming of the planet. Speaking by video to a climate conference in Los Angeles, Mr. Obama repeated his campaign vow to reduce climate-altering carbon dioxide emissions by 80 percent by 2050, and invest $150 billion in new energy-saving technologies. “Now is the time to confront this challenge once and for all,” Mr. Obama said. “Delay is no longer an option. Denial is no longer an acceptable response.” link Energy price will shoot back up if he gets his way.
