Sign of Global Warming: Ice Shelf Fracture

In 1998, the research community warned: “Antarctic Peninsula ice shelves have been in rapid retreat for the last few decades, apparently in response to a regional climate warming of 4.5 degrees F since the 1940s. Although the rate of warming is several times that of the global average, the exact cause of the warming is not known.” “This may be the beginning of the end for the Larsen Ice Shelf, In 2002, they announced: “Larsen B Ice Shelf Collapses in Antarctica, An Antarctic ice shelf that was 200 metres thick and had a surface area of 3,250 square kilometres has broken apart in less than a month. ” the speed of it is staggering, “[It is hard] to believe that 500 billion tonnes of ice sheet has disintegrated in less than a month” “The retreats are attributed to a strong climate warming in the region.” In 2003, the scientists announced: “The Arctic’s largest ice shelf has broken up. Climate change is the leading culprit.” The Ward Hunt Ice Shelf has been floating on the sea surface, attached to the north coast of Canada’s Ellesmere Island for around 3,000 years. In spring of last year, large fractures suddenly appeared; by that August the shelf had broken in two. The weakening of the ice shelf appears to be the result of rapid warming in the Arctic, say the researchers. “The climate change seems to be occurring at a faster rate than before the 1990s, says Jeffries. Recent collapse of ice shelves in the Antarctic has also been blamed on climate change. Difficult not to believe that climate change is occuring at a rapid pace.
