Meanwhile, the margin of the massive Jakobshavn glacier has retreated inland further than it has at any time in the past 150 years it has been observed. Researchers believe that the glacier has not retreated to where it is now in at least the last 4,000 to 6,000 years.

This image is a false-color (near-infrared, green, blue) view acquired by the Multi-angle Imaging SpectroRadiometer’s nadir camera. The brightness of vegetation in the near-infrared contributes to the reddish hues; glacial silt gives rise to the green color of the water; and blue-colored melt ponds are visible in the bright white ice. A scattering of small icebergs in Disco Bay are visible.
