BBC: 'Drastic' shrinkage in Arctic ice

BBC NEWS | Science/Nature | 'Drastic' shrinkage in Arctic ice: "A Nasa satellite has documented startling changes in Arctic sea ice cover between 2004 and 2005.

The extent of 'perennial' ice - thick ice which remains all year round - declined by 14%, losing an area the size of Pakistan or Turkey [or Texas].

The last few decades have seen summer ice shrink by about 0.7% per year."
