Glaciers in the French Alps have lost a quarter of their area in the past 40 years, according to new research.
In the late 1960s/early 1970s, the ice fields slipping down Mont Blanc and the surrounding mountains of the European range covered some 375 sq km.
By the late 2000s, this area had fallen to about 275 sq km.
The research has been presented at the American Geophysical Union (AGU) Fall Meeting, the world's largest annual gathering of Earth scientists.
