Scientists studying the 2002 collapse of the Larsen Ice Shelf believe they have conclusive proof that the cause is human in origin.

The 2002 event can now be pinned down to a specific change in climate, which is in turn linked to human-induced global warming, the authors say. Some argue that this is the first single event proved to have been caused by manmade climate change. "It's close to being evidence," says Ted Scambos, lead scientist of the National Snow and Ice Data Center at the University of Colorado in Boulder.

It is believed that westerly winds circulating the south pole have strengthened over the past 50 years. They believe this to be caused by an increase in CO2 emissions combined with the CFC created ozone hole.
