Rising seas is the biggest threat to the Antarctic polar ice.
But behind last year's big ytsmältningar on Västantarktis low instead of hot air, reports the Vetenskapsradion.
the ice cap at the Västantarktis is larger than Mexico and suffered in January 2016 of the comprehensive smältningar on the surface.
the Researchers believe that it is due to El Niño, a weather phenomenon that occurs in the Pacific ocean, was unusual sharply in 2015 and 2016.
This meant that hot air was sent towards the Västantarktis.
Per Holmlund, professor of glaciology, see ytsmältningen as a warning.
