The Arctic and Antarctic are experiencing severe climate change. The Arctic ice cap is melting at an unprecedented rate due to human induced global warming, according to a new study
conducted by 300 scientists and elders from native communities in the
arctic, released 8 November. Over the last 30 years the ice cap has
shrunk 15-20 per cent. In 2003 the Ward Hunt Ice Shelf,
the largest in the Arctic, broke into two pieces. With the build up of
greenhouse gases, primarily carbon dioxide, the trend is set to
accelerate with forecasts that by the summer of 2070 there maybe no ice
In Antarctica, while the interior of the continent is cooling, disappearin g sea ice and warmer temperatures around the Antarctic peninsula are causing an 80 percent drop in the numbers of Antarctic Krill.
This is causing the food chain to crash affecting fish, penguins, sea
birds, whales and other animals, as well as commercial Fisheries. The
breakup of the Larsen B ice shelf in 2002 has also released several
glaciers, increasing their speed up to eight fold, and dumping their
loads into the Weddell Sea contributing to rising sea level.
