Changes to the Antarctic ice sheet at the bottom of the southern hemisphere have been triggered by sea level changes in the northern hemisphere over the past 40,000 years, a new study discovered. New models found that as the climate cooled in the northern hemisphere and more water turned to ice, sea levels in Antarctica dropped, making its ice sheet grow. Likewise, as temperatures rose again, the ice sheets in the Northern Hemisphere retreated, causing levels to rise around Antarctica and its ice sheet to retreat. The only possible explanation, the scientists say, were changes in sea level caused by the growth or retreat of ice sheets in the Northern Hemisphere. 'In the modern era, we haven't seen the kind of large ice sheet retreat that we might see in our future warming world.
