Parts of Antarctica have actually gained ice during the last 20 years, new research reveals, despite the continent suffering significant loss due to global warming.
Researchers say that sea ice, pushed against ice shelves by a change in regional wind patterns, may have helped to protect these ice shelves from losses.
Ice shelves are floating sections of ice attached to land-based ice sheets and they help guard against the uncontrolled release of inland ice into the ocean.
During the late 20th century, high levels of warming in the eastern Antarctic Peninsula led to the collapse of the Larsen A and B ice shelves in 1995 and 2002, respectively.
These events drove the acceleration of ice towards the ocean, ultimately accelerating the Antarctic Peninsula’s contribution to sea level rise.
