Climate change melts Montana's famous glaciers

In the US state of Montana, the Glacier National Park - an area sometimes called the "Crown of the Continent" - is famous for its snow-capped mountains. But it could soon lose its glaciers due to global warming. Scientists warn if the ice keeps melting at this rate, the park's 25 remaining glaciers could all melt away by the year 2030. Al Jazeera's Rob Reynolds reports from Glacier National Park.
