...s from entering the atmosphere. "It's one thing to say that underground is a great place to store carbon dioxide, but it's another thing to be able to prove it as we have done," said Rostron, from the U of A's Faculty of Science and a co-author on a paper appearing today in GSA Today, a journal published...Melting ice cap gives urgency to new census of marine life project in Arctic Ocean
