NEW YORK -- Emissions of the greenhouse gas methane due to human activity were roughly 1.5 times greater in the United States in the middle of the past decade than prevailing estimates, according to a new analysis by 15 climate scientists published Monday in the Proceedings of the National Academy of Sciences.
The analysis also said methane discharges in Texas and Oklahoma, where oil and gas production was concentrated at the time, were 2.7 times greater than conventional estimates. Emissions from oil and gas activity alone could be five times greater than the prevailing estimate, the report said.
Its conclusions are sharply at odds with the two most comprehensive estimates of methane emissions, by the U.S. Environmental Protection Agency and an alliance of the Netherlands and the European Commission.

WikiLeaks charges unlikely
WASHINGTON -- The Justice Department has all but concluded it will not bring charges against WikiLeaks founder Julian Assange for publishing classified documents because government lawyers said they could not do so without also prosecuting U.S. news organizations and journalists, according to U.S. officials.
The officials stressed that a formal decision has not been taken, and a grand jury investigating WikiLeaks remains impaneled, but they said there is little possibility of bringing a case against Mr. Assange, unless he is implicated in criminal activity other than releasing online top secret military and diplomatic documents.
