The Arctics sea ice melted at a record pace in 2012, the ninth-hottest year on record, compounding concerns about climate change underscored by extreme weather such as Hurricane Sandy, the UN weather agency said Thursday.
In a report on the situation in 2012, the World Meterological Organisation said that during the August to September melting season, the Arctics sea ice cover was just 3.4 million square kilometres (1.32 million square miles).
That was a full 18 percent less than the previous record low set in 2007. WMO Secretary-General Michel Jarraud dubbed it a disturbing sign of climate change.
The year 2012 saw many other extremes as well, such as droughts and tropical cyclones. Natural climate variability has always resulted in such extremes, but the physical characteristics of extreme weather and climate events are being increasingly shaped by climate change, he said. For example, because global sea levels are now about 20 centimetres higher than they were in 1880, storms such as Hurricane Sandy are bringing more coastal flooding than they would have otherwise, he added.
