Hækkun á yfirborði sjávar

Mun yfirborð sjávar drekkja borgum ef hitastig Jarðar hækkar? "The only other masses of ice on the planet that can contribute to sea level rise are the non-polar glaciers, but they are very few and far between. The biggest is the Himalayan ice cap, but it's so high that a substantial portion will always remain. Most of the rest are teeny objects tucked away in high elevation nooks and crannies, like our Glacier National Park."
