In this image of 05 August 2017, the Copernicus Sentinel-2B satellite takes over one of the most rapidly changing glaciers in the world - Columbia Glacier, located in Alaska.
The glacier, which can be seen just below the middle of the image, flows down the snow-covered slopes of the Chugach Mountains into the Prince William Sound in south-east Alaska.
Over the last three decades, this tidewater glacier has retreated more than 20 km and lost about half of its total thickness and volume. The changing climate is thought to have nudged it into retreat in the 1980s, resulting in its end – or terminus – breaking off.
