Here’s a story from our new book “Overview Timelapse” that’s particularly relevant now, as scientists announced this week that the Greenland and Antarctic ice sheets are tracking the United Nations’ worst-case scenarios for melting and sea level rise. Click below to learn more:
Each year during the spring and summer, the surface of Greenland transforms from a solid white to one where blue streams and lakes emerge. This melting contributes directly to sea level rise because the water that is frozen here is situated on top of a large land mass (in contrast to floating sea ice that makes up much of the rest of the Arctic ice). In this Timelapse, clear differences in ice coverage and melting can be observed at roughly the same time of year from 2014 to 2016. Scientists estimate that half of the ice loss from Greenland has been caused by increased air and surface temperatures and the other half from the speeding up of the flow of ice into the sea from glaciers, propelled by a warmer ocean.
