Washington Post's Sarah Kaplan takes us to Greenland where scientists are drilling through the ice to predict the future of climate change. This means drilling thorough 1600 feet of ice to reach the bedrock below. Scientists can analyze the rocks to find when a glacier last melted. The agile subgeological ice drill drills through 500 metres of ice from the US National Science foundation- amazing. If the whole of Greenland ice sheet melted it would raise sea water levels by 24 feet devastating coastlines.
