To see how deeply interconnected the planet truly is, look no further than the massive ice sheets on the Northern Hemisphere and South Pole. The analysis, published in Nature, shows for the first time that changes in the Antarctic ice sheet were caused by the melting of ice sheets in the Northern Hemisphere. The influence was driven by sea-level changes caused by the melting ice in the north during the past 40,000 years. Understanding how this works can help climate scientists grasp future changes as global warming increases the melting of major ice sheets and ice caps, researchers said. And researchers also looked at markers of past shorelines to see how the ice sheet’s edge has retreated.
