an Antarctic ice shelf the size of Jamaica has detached itself from the antarctic peninsula.
"Computer models have long predicted that decreasing sea ice should amplify temperature changes in the northern polar region. Julienne Stroeve, from the US National Snow and Ice Data Center, told a meeting of the American Geophysical Union that this process was under way.
Arctic ice cover in summer has seen rapid retreat in recent years."
