text:  One of North America's largest areas of interconnected glaciers is melting twice as quickly as it did before 2010. That's the worrying finding of a team of scientists. The Juneau ice field sprawls across the coastal mountains of Alaska and British Columbia. But new research published suggests that not only is it melting twice as fast as it was less than two decades ago, but it's also melting five times faster than it was in the 1980s.
