Shrinking Lakes on the Mongolian Plateau

Lakes on the Mongolian Plateau are shrinking rapidly, according to researchers from Peking University and the Chinese Academy of Sciences. After analyzing several decades of satellite imagery, the researchers found that the total lake surface area had declined from 4,160 square kilometers (1,060 square miles) in the late 1980s to 2,900 square kilometers in 2010, a decrease of 30 percent.

Dissapearing coastal villages

Coastal erosion is in the UK a serious problem. For the residents of Skipsea, on the Holderness coast in the North East of England, coastal erosion is a fact of life. As the years pass the village has seen the sea claim more and more land and its future is far from certain.

The melting season of Greenland’s ice sheet

It appears that Greenland’s melt season is making up for lost time. 

After a cool spring kept Greenland’s massive ice sheet mostly solid, a (comparatively) warm late June and early July have turned half the ice sheet’s surface into liquid, well outside the range of normal for this time of year.

 Despite the ice sheet’s remote location, its slushy fingers reach across the globe, influencing sea levels and how fast the Gulf Stream current moves. As temperatures rise, its influence could grow larger as major summer melt events become regular occurrence.

Recent warming has already contributed to ice loss in some areas previously thought to be stable and sped the trip of some glaciers into the sea.
