Although there have been a few demonstrations that it is possible to store relatively small amounts of CO2 deep below the ground — largely to push more oil and natural gas to the surface — there is no commercial - scale power plant that both captures and stores greenhouse gases, Moniz adds.

While this represents a much smaller percentage of overall greenhouse gases than carbon dioxide, methane is about 20 times more effective at trapping heat.

Each OCO - 2 reading will sample a column of the atmosphere above roughly 3 square kilometers of Earth's surface — much smaller than the 85 - square - kilometer footprint of a similar Japanese probe, the Greenhouse Gases Observing Satellite (GOSAT), which launched in 2009 and is still operating.
