“We need a world-wide standard and a world-wide plan of action” to address climate change, says Jeffrey Sachs, director of The Earth Institute at Columbia University, in conversation with former Vice President Al Gore and Jennifer Granholm. The barrier to standards has been money and influence in countries like the U.S., which the world expects to act first. “There are four anti-climate change lobbyists on Capitol Hill for every member of the House and Senate,” Gore says. But there is a silver lining: “I think we are going to solve this but we have got to have more action by the Congress,” Gore says.
