LITTLE ROCK, Ark. (AP) – Former Vice President Al Gore says the American media and outsize effect of corporate money in politics are partially to blame for inaction on global climate change.

In wide-ranging remarks during an appearance Monday evening at the Clinton Presidential Library, Gore said journalists should have done a better job questioning the 2012 presidential candidates about climate change. He railed against what he called the corrupting influence of money in politics.

Gore also defended the recent sale of his television network, Current TV, to Al-Jazeera. He said the Qatar government-owned network had a better track record of climate change reporting than some of its U.S.-based counterparts.
