      The surface ice on Earth has decreased by about 40% between 1979 and 2010, approximately 14% per decade. Worryingly, that’s an area larger than Alaska and California combined. Across the globe, surface ice is changing: “The famed snows of Kilimanjaro have melted more than 80 percent since 1912. Glaciers in the Garhwal Himalaya in India are retreating so fast that researchers believe that most central and eastern Himalayan glaciers could virtually disappear by 2035. Arctic sea ice has thinned significantly over the past half century, and its extent has declined by about 10 percent in the past 30 years. NASA’s repeated laser altimeter readings show the edges of Greenland’s ice sheet shrinking.” (reference: https://www.nationalgeographic.com/environment/global-warming/big-thaw/).
      It’s very hard to predict how long until the ice bergs melt, although surface temperatures of the Earth seem to be increasing which will continue to heat the ice and cause a rising sea level. This will have devastating impact on the animals which depend on the ice for their habitat or source of food.
