FILE - In a Thursday Oct. 6, 2011 file photo, ExxonMobil Chairman and CEO Rex Tillerson addresses the third annual Washington Ideas Forum at the Newseum in Washington. Tillerson says fears about climate change, drilling, and energy dependence are overblown. In a speech Wednesday, June 27, 2012, Tillerson acknowledged that burning of fossil fuels is warming the planet, but said society will be able to adapt. The risks of oil and gas drilling are well understood and can be mitigated, he said. And dependence on other nations for oil is not a concern as long as access to supply is certain, he said(AP Photo/Manuel Balce Ceneta, File)
