SHELDON GLACIER, Antarctica (Reuters) - More rain on the Antarctic Peninsula is speeding a melt of glaciers such as the Sheldon, which has retreated 2 km (1.2 miles) in 20 years and is nudging up world sea levels, a leading expert said.
"Rain is very corrosive to glaciers and at least in part the reason this glacier is retreating," David Vaughan, a British Antarctic Survey glaciologist, said on an inflatable speedboat in a bay that had been blanketed by ice for thousands of years.

The ice cracks and growls as the 70-meter-high (230 feet) ice cliffs at the front of the Sheldon glacier slide downhill, some of the ice a bluish white. Icebergs sometimes split off into the sea, where penguins and seals swim.
