Is the Antarctic ice sheet melting more rapidly because of manmade global warming? While some believe this to be the case, new research from Western Australia’s Curtin University appears to reveal otherwise. As reported in The Australian News, researchers using acoustic sensors at places in the Pacific and Indian ocean spent more than six years listening to cracking ice to determine if icebergs were peeling off Antarctica more rapidly. The system of underwater sensors, or hydrophones, were of the same variety used to detect underground nuclear explosions, and they found that after years of listening to snaps and cracks there do not appear to be any significant climatic trends of melting ice. Sounds like good news for Happy Feet!
