A team of scientists are staring climate change in the eye, the New York Times reports, setting sail for the infamous “Doomsday Glacier” in Antarctica in an attempt to study it up close. The enormous Thwaites Glacier, at roughly the size of Florida, harbors enough water to raise sea levels across the globe by over two feet should it melt completely. On Saturday, a crew of nearly 40 researchers left on a ship from a port in New Zealand to get more answers. A number of intriguing experiments are slated, but everyone’s going in knowing that all won’t go according to plan. Scientists fear that the glacier’s melting could trigger a collapse of the broader West Antarctic ice sheet.
