Author Bill McKibben and a group of activists have found the old solar panels that Jimmy Carter installed atop the White House, and that Ronald Reagan removed. McKibben's group 350.org has been hauling the panel on a publicity road trip to DC to urge Barack Obama to reinstall them. The symbolism has everything to do with the fossil industry's victory in quashing climate legislation, the future of a world climate treaty, and the political future of a president whom environmentalists see as AWOL on his campaign promises. McKibben has booked a meeting with Obama for today.
