A national park in the US has lost two more of its glaciers to climate change and many of the rest may be gone by decade's end.
Warmer temperatures have reduced the number of named glaciers in Montana's Glacier National Park to 25, said US Geological Survey ecologist Dan Fagre. "When we're measuring glacier margins, by the time we go home the glacier is already smaller than what we've measured,'' Mr Fagre said yesterday.
The latest two to fall below the 10ha threshold, the minimum size required for the glacier to have a name, were Miche Wabun and Shepard.
Each had shrunk by about 55 per cent since the mid-1960s.
The largest remaining glacier in the park is Harrison Glacier, at about 190ha.
The melt-off does not reveal what is causing temperatures to rise.
