Across the U.S., the news media are coping with another week of cripplingly typical temperatures. 'It's awful,' said Jim Moore, editor of The Knoxville News-Sentinel.

Tom Pierre, news director of Fox affiliate KABB-TV in San Antonio, was equally distraught. 'Yesterday, it was a pleasant 73 degrees,' Pierre said. 'How is a 92-year-old widow supposed to tragically perish in an unventilated tenement apartment with weather like that?'
