A rock that absorbs CO2? This is more science fiction, right? Not so, says Juerg Matter, a scientist from Columbia University's Lamont-Doherty Earth Observatory. In a study published last month in Proceedings of the National Academy of Sciences, Matter suggests that a simple hunk of peridotite could be the answer to at least some of our global warming woes. Solid.
