A methane leak, seen from space, proves to be far larger than thought

The first satellite designed to continuously monitor the planet for methane leaks made a startling discovery last year: A little known gas-well accident at an Ohio fracking site was in fact one of the largest methane leaks ever recorded in the United States.

The findings by a Dutch-American team of scientists, published Monday in the Proceedings of the National Academy of Sciences, mark a step forward in using space technology to detect leaks of methane, a potent greenhouse gas that contributes to global warming, from oil and gas sites worldwide.
