“Can we turn carbon dioxide to stone to fight climate change?”

“As more heat-trapping carbon dioxide continues to concentrate in our atmosphere — and to wreak havoc on our climate — scientists are desperately seeking solutions. Some are looking for ways to limit the greenhouse gas we spew from smokestacks, tailpipes and the like; others, whose efforts remain largely under the radar, are aiming to thin the layer of gas that already blankets our planet. One group of researchers in Canada, taking the latter approach, may have hit upon a novel yet ancient idea: harness and accelerate the carbon-absorbing power of rocks.”
