McCain: 'Why should he talk about climate change when we have got 130,000 people in Syria killed?' "John Kerry and the president, they could be hitting the trifecta here. Gross failure on all three. So he has to go over to Asia and talk about climate change and say it's the most important issue? Hello? On what planet does he reside?" he said Tuesday. McCain coauthored cap-and-trade bills in 2003, 2005, and 2007, but later moved away from focusing on climate and voted in favor of thwarting EPA's greenhouse gas regulations.
