new balance 480 ,500 years earlier. This confirms that once ice sheets start to melt, they can do so very quickly.The melting of the Cordilleran Ice Sheet likely caused about 20 feet of sea level rise and big changes in ocean temperature and circulation. Because cold water is denser than warm water, the water contained by ice sheets sinks when it melts, disrupting the 鈥済lobal conveyor belt鈥?of ocean circulation and changing climate.Res
