Methane On Mars May Indicate Living Planet 200
Riding with Robots writes "NASA is announcing today that the definitive detection of methane in the Martian atmosphere means the planet is still alive, at least geologically, and perhaps even biologically. 'Methane is quickly destroyed in the Martian atmosphere in a variety of ways, so our discovery of substantial plumes of methane in the northern hemisphere of Mars indicates some ongoing process is releasing the gas,' said one agency scientist. The gas was detected with observations made over over several Martian years with NASA telescopes at Mauna Kea, Hawaii. Both biological and geological processes could explain the methane."

It's not worse than CO2, because it decays relatively quickly in the atmosphere. That's why this find is significant, it means the methane hasn't been in the atmosphere that long, which means there's still an active process on Mars that's putting it there.

The methane plumes started to show up in the northern hemisphere spring of Mars, gradually building up and peaking in late summer. At one point during the study, the primary plume contained about 19,000 metric tons (21,000 tons) of methane, comparable to the amount produced at the massive hydrocarbon seep at Coal Pit Point in Santa Barbara, Calif.
