West Antarctic Ice Sheet warming twice earlier estimate http://apocadocs.com/s.pl?1356300721
A new analysis of temperature records indicates that the Western Antarctic Ice Sheet is warming nearly twice as fast as previously thought.
US researchers say they found the first evidence of warming during the southern hemisphere's summer months.
They are worried that the increased melting of ice as a result of warmer temperatures could contribute to sea-level rise....
The results indicate an increase of 2.4C in average annual temperature between 1958 and 2010.
"What we're seeing is one of the strongest warming signals on Earth," says Andrew Monaghan, a co-author and scientist at the US National Centre for Atmospheric Research....
"The fact that temperatures are rising in the summer means there's a prospect of WAIS not only being melted from the bottom as we know it is today, but in future it looks probable that it will be melting from the top as well," he said.
