The impact of global warming:
Ice crashes down from the Perito Moreno Glacier off Argentina last year.
The affected area is at the far northern tip of the Antarctic, just south of Chile and Argentina. Temperatures there have risen by up to 2.5 degrees C in the past 60 years - faster than almost any region in the world.
In the past 30 years, ice shelves in the region have lost more than 13,500 sq km of area.
