Methane is a potent greenhouse gas. Could turning it into CO2 fight climate change?
Usually, choosing between the lesser of two evils is a dismal decision. But sometimes, it's an opportunity.
A case in point: Turning methane (a powerful greenhouse gas) into carbon dioxide (also a planet-warming pollutant) could help fight climate change, researchers say.
It's not that CO2 isn't a problem - it's the main problem. But on a molecule-for-molecule basis, methane traps more heat, so converting it into something less potent would reduce its climate impact.
In fact, by restoring the concentration of methane in the atmosphere to preindustrial levels, this counterintuitive strategy could eliminate about a sixth of human-caused warming, according to a paper published Monday in Nature Sustainability. And it would add only a few months' worth of CO2 emissions
