Glaciers and ice caps in the Canadian Arctic Archipelego have started melting. This will contribute to sea-level rise for the remainder of the 21st century. That’s a problem because the area contains one-third of the global volume of land ice outside the ice sheets.
Researchers found that the islands lost about 61 gigatonnes of ice per year from 2004 to 2009, enough to raise global sea levels about a millimeter in that time.
That rate of melt will only increase in the years ahead. More mass into the world’s oceans and more heat accumulated from global warming means the rate that sea level rise is increasing will also increase. And because of the out-sized influence of the dirty energy industry and its apologists, we remain unprepared for that situation. Preparing for it will only become more expensive with time.
