Texas became the first state to challenge the federal government's finding that greenhouse gases are dangerous to people, claiming Tuesday that the ruling is based on flawed science. The state is asking a federal appeals court to review the Environmental Protection Agency's December finding. GOP Gov. Rick Perry said Texas' industry and agriculture would be damaged by the finding and regulations that could result. Texas Attorney General Greg Abbott said the EPA's research should be discounted because it came from the "scandal-plagued" Intergovernmental Panel on Climate Change. Al Armendariz, EPA regional administrator over Texas, said the finding will withstand legal action. Court to review Abu Ghraib conviction The U.S. military's highest court said it will review the conviction of an Army reservist who prosecutors said was the ringleader of detainee abuse at Abu Ghraib prison in Iraq. Former corporal Charles Graner was sentenced in 2005 to 10 years in prison for his role in the scandal. The U.S. Court of Appeals for the Armed Forces in Washington said it will consider whether the trial judge erred by refusing to let jurors see memos approving "enhanced interrogation tactics" for detainees. Graner of Uniontown, Pa., was accused of stacking naked prisoners in a human pyramid and ordering them to masturbate while soldiers took photos. Bloomberg defends trial cost estimate New York City Mayor Michael Bloomberg defended his claim that it would cost $200 million per year to secure the city during a trial of 9/11 suspects. On Sunday, Vice President Biden said that estimate is too high. Bloomberg said Tuesday that the estimate is "based on many years of experience and knowing what the costs are in a big city of deploying the greatest police department in the world." Bloomberg once supported but now opposes the Obama administration's plan to try the 9/11 suspects in a federal courthouse in Manhattan. Biden said the administration is considering its options. Climber's body retrieved from crater The body of a veteran climber who fell 1,500 feet into the crater atop Mount St. Helens was recovered Tuesday after he spent more than a day in the snow, authorities said. Clouds and wind had hampered efforts to reach Joseph Bohlig, 52, who was posing for a picture on the rim when a snow overhang gave way and he fell into the Washington volcano. A Navy helicopter crew found his body, Skamania County Undersheriff David Cox said. Bohlig had climbed the volcano 68 times before the accident, Cox said. The volcano, south of Seattle, exploded in 1980 but has been quiet in recent years. NYPD officers won't face second trial Three New York police officers who killed an unarmed black man in a 50-shot barrage outside a strip club hours before his wedding will not face civil rights charges, the Justice Department said. The parents and former fiancée of Sean Bell, 23, had lobbied federal prosecutors in Brooklyn to charge the officers with violating Bell's civil rights after they were acquitted in state court. The Justice Department said there was insufficient evidence.

On Deadline: What others are reporting Georgia zooms in on too-slow drivers Lawmakers in Georgia are reviewing a proposal to fine drivers who travel too slowly in the far-left passing lane, the 11 Alive TV station in Atlanta reported (11alive.com). The bill would fine motorists $75 for driving much slower than the speed limit in the left lane of Georgia highways and interstates. "They're ... causing people to weave in and out of traffic in order to get around slower drivers, which also causes a much larger hazard," GOP state Rep. Mark Butler, who introduced the measure, told the station. If approved, the bill would take effect in July. Said Butler: "We're just trying to get people to quit clogging up the lane that's supposed to be used for passing." — Melanie Eversley Mardi Gras to the max: Revelers strut through the French Quarter on Fat Tuesday, the final day before Lent starts.
