During two days of intensive airborne measurements, oil and gas operations in Colorado’s Front Range leaked nearly three times as much methane, a greenhouse gas, as predicted based on inventory estimates, and seven times as much benzene, a regulated air toxic. Emissions of other chemicals that contribute to summertime ozone pollution were about twice as high as estimates, according to the new paper, accepted for publication in the American Geophysical Union’s Journal of Geophysical Research: Atmospheres.

There is methane in the Martian atmosphere, and it’s relatively abundant. But not only that, it peaks seasonally and in specific locations, suggesting that something–geological, chemical or perhaps even biological–is burping methane. But the problem is that no one knows what is producing the methane, or why it’s like a kid with a short attention span: most of the methane in the Martian atmosphere wanders off in less than a year, much more quickly than dissipating air should.
