?Maps will need to be redrawn?: A massive chunk of ice broke away from Antarctica, producing one of the largest icebergs ever recorded

A chunk of floating ice that weighs more than a trillion metric tons broke away from the Antarctic Peninsula, producing one of the largest icebergs ever recorded and providing a glimpse of how the Antarctic ice sheet might ultimately start to fall apart. A crack more than 120 miles long had developed over several years in a floating ice shelf called Larsen C, and scientists who have been monitoring it confirmed on Wednesday that the huge iceberg had finally broken free.
Glaciers form when there is a build up of ice and snow. If there was global warming there would be less build up of ice and snow on the Antarctic ice sheet, which causes glaciers to expand outwards. In the 11 years since An Inconvenient Truth was released, not one of their predictions has come true. Can't deny what isn't true.
Q: What is the significance of this more than 2,000-square-mile iceberg breaking off? Ted Scambos, a senior research scientist with the National Snow and Ice Data Center in Boulder, Colorado SCAMBOS: It's a major change to this ice shelf ? a very large iceberg and the remaining ice shelf is smaller than it has ever been in human experience. It's an example of how the polar regions can change on a massive scale, even in just a few years or decades. And it shows us that, while we can observe this continent in great detail now, we're only seeing it clearly for the past few decades and it still has a lot to teach us.
