Antarctica’s Ice May Collapse Again – Scientists Just Found Proof
http://youtu.be/AxDDvk6Fdvo
Scientists just drilled through about 1,700 feet of Antarctic ice and pulled up a record-breaking core. It’s a 750-foot tube that reaches back about 23 million years. When the drilling crew finally cracked open their giant tube of dirt, the mud was filled with marine fossils – the physical remains of ancient ocean bugs. The core showed that this part of West Antarctica had been an open ocean back then. That means the ice sheet had collapsed before. Watch now to see why this discovery is raising concerns worldwide.
