Heat makes Pat Robertson a global warming "convert" 1 hour, 55 minutes ago Conservative Christian broadcaster Pat Robertson said on Thursday the wave of scorching temperatures across the United States has converted him into a believer in global warming. "We really need to address the burning of fossil fuels," Robertson said on his "700 Club" broadcast. "It is getting hotter, and the icecaps are melting and there is a buildup of carbon dioxide in the air." This week the heat index, the perceived temperature based on both air temperatures and humidity, reached 115 Fahrenheit in some regions of the U.S. East Coast. The 76-year-old Robertson told viewers that was "the most convincing evidence I've seen on global warming in a long time." Last year, Robertson said natural disasters affecting the globe, including hurricanes Katrina and Rita that wrecked the U.S. Gulf Coast, might be signs that the biblical apocalypse was nearing. The issue has divided conservative Christians. In October, Robertson, a former Republican presidential candidate, said the National Association of Evangelicals was teaming up with "far left environmentalists" for saying global warming was caused by humans and needed to be mitigated. Signers of that statement included California mega-church pastor Rick Warren, author of the bestselling "The Purpose Driven Life." In the late 1990s, Robertson paid at least $300,000 to investigate the revival of an oil refinery east of Los Angeles. The bid was unsuccessful.
