Copenhagen - Danish researchers have provided further evidence to suggest how the North Pole's ice cap is shrinking, reports said Monday. "The ice cap is at an extreme low. For the 50 years we have data from, we have never seen anything like it," Leif Toudal Pedersen of the Technical University of Denmark told the Jyllands-Posten newspaper.
A survey based on satellite imagery from Sunday suggested that the ice cap was 40 to 45 per cent less - or a reduction of 2.5 million square kilometres - than on average during the period 1997-2000, the newspaper reported.

Global warming was a contributing factor, but this year strong currents have also swept large masses of ice from Siberia via the North Pole past eastern Greenland and further south where it melted, Pedersen said.
Ice free summers in the North Pole area could be a reality in 15 to 20 years as opposed to previous projections of 30 to 40 years, he said.
