As the Paris climate summit draws to a close and world leaders scramble to find more ways to make a dent in humanity’s carbon problem, a commonsense but oft-ignored strategy has made its way onto the table: sticking carbon back in the soil.
What do we do with a problem like carbon dioxide? We want to remove the excess from our atmosphere, but how? In Iceland, geologists are burying the greenhouse gas with water, so that basic chemistry can turn it into solid rock inside what the New York Times calls "a geological soda machine."
As the Arctic ice continues to fade away, some scientists have come up with radical solutions to the problem of greenhouse gases. One of these ideas is large-scale Carbon Capture and Storage (CSS), burying those troublesome gases underground — but now it looks like that notion could cause more trouble than it's worth.
