The glaciers of Iceland - which form Europe's largest icecap - have been steadily shrinking for the past 30 years. As they have melted, their waters have eroded and reshaped the terrain of Iceland every summer. These aerial views show a landscape morphing as every drop of water quickly flows from glacier to sea. By 2050, Iceland is projected to lose 30 percent of its glacial mass, and could be almost entirely ice-free a hundred years after that.
