Longest New Zealand glacier shrinking 500 metres a yearApril 24th, 2008 - 2:01 pm ICT by admin
Wellington, April 24 (DPA) The Tasman Glacier - New Zealand’s longest - is retreating at the rate of more than 500 metres a year because of global warming, a scientist said Thursday. Martin Brook said that the glacier, which sweeps past Mount Cook, the country’s highest peak, in the Southern Alps, was melting into a lake that began to form only 35 years ago and was now seven kilometres long and two kilometres wide.
He told Radio New Zealand that the lake was likely to more than double in length to 16 km over the next 20 years.
“It’s just too warm for a glacier to be sustained at such low altitude, 730 metres above sea level, so it melts rapidly,” said Brook, a glaciologist at Massey University.
The Tasman Glacier, once 29 km long, was reported last year to have shrunk to 23 km.
It has long been one of New Zealand’s biggest attractions for tourists, who take bus trips and scenic flights by helicopter and ski-planes from the Mount Cook village to view the glacier.
