KR Washington Bureau 01/10/2006 Rapidly shrinking Arctic ice could spell trouble for the rest of the world: "Alarmed by an accelerating loss of ice in the Arctic Ocean, scientists are striving to understand why the speedup is happening and what it means for humankind. If present trends continue, as seems likely, the sea surrounding the North Pole will be completely free of ice in the summertime within the lifetime of a child born today. The loss could point the way to radical changes in the Earth's climate and weather systems. "
