An analysis of temperature recordings taken in West Antarctica has revealed that temperatures in West Antarctica have increased by 2.4 degrees Celsius.
Although the temperature increase seems small, it is three times higher than the global average, and twice more than the temperatures scientists had previously projected. The data means that West Antarctica is one of the fastest-warming places on the Earth, says David Bromwich, a researcher from the Byrd Polar Research Center in Ohio.
Scientists believe the melting West Antarctic Ice Sheet (WAIS) has already contributed about 10% to the rise in the world’s sea level. A continued temperature increase in the area will speed up the melting of the WAIS. If the WAIS melts even more, towns and cities located close to the sea will get flooded.
If the WAIS disintegrates or melts completely, the world’s sea level would rise by at least 3.05 meters, although scientists say the ice sheet would take several hundred years to disintegrate.
In 2007, the Intergovernmental Panel on Climate Change, a research group set up by the United Nations, calculated that sea levels would rise 18 to 59 centimeters by the year 2100.
However, last June 2012, the US National Research Council said they believed that sea levels would rise two to three times higher than the UN panel’s calculation.
