Changes in Snow and Sea Ice in the Arctic

e. As the Arctic warms, ice (both
terrestrial ice and snow, and sea ice) melts, amplifying warmth. And with the loss of terrestrial ice, sea level rises. Because the feedback processes responsible for the observed Arctic amplifica tion in the past remain active today, it is very likely that Arctic amplification will continue for the foreseeable future, With this amplification, sea ice will continue to contract, and glaciers and ice sheets will experience accelerated melting, with concomitant increases in the rate of sea level rise.
