Last month, our reporter @henryfountain spent a week in Oman, looking at rocks. “Sounds pretty boring, I know,” he writes. “But these weren’t just any rocks.” These rocks could help save the planet. They remove planet-warming carbon dioxide from the air and turn it to stone. Scientists say that if this natural process could be harnessed, accelerated and applied inexpensively on a huge scale — some very big “ifs” — it could help fight #climatechange. The carbon-capturing formations in Oman are in a slice of oceanic crust and the mantle layer below it that was thrust up on land nearly 100 million years ago. When they’re exposed to air or water as they are in Oman — among other places — they’re like a giant battery with a lot of chemical potential. “They’re really, really far from equilibrium with the atmosphere and surface water,” said Peter B. Kelemen, a geologist who’s been studying the rocks for more than 2 decades. @vincent_fournier_paris took this photo in Oman.
