Today we review research from Sweden aimed at detecting methane, a highly radiative and invisible greenhouse gas, whose importance is being heightened by fracking natural gas in North America and elsewhere and the difficulty in measuring and monitoring it as part of climate change mitigation and action plans. The application of the new method uses a camera to record a high resolution spectrum and selects the methane contribution. This may be applied to sewage sludge deposits, combustion processes, animal husbandry and lakes as well as the vast areas of bogs and marshes that make up northern Canada and Russia. The present study used a camera on the ground but plans are to make it airborne for larger scale methane mapping.
