• A forest by any other name?
Semantics, carbon implications, and solutions
Using the world’s first global, Landsat-based 30-meter resolution map of tree cover, researchers found that ambiguity of the term “forest” has the potential to create 13 percent discrepancies in forest area maps. While ecologists have long [...]

• New Global Data Finds Tropical Forests Declining in Overlooked Hotspots
The world lost more than 18 million hectares (45 million acres) of tree cover in 2014, an area twice the size of Portugal, according to new data from the University of Maryland (UMD) and Google released by Global Forest Watch. The data find that [...]

• Turkish Glaciers Shrink By Half
Researchers and citizens have known for some time that Turkey’s glaciers are shrinking. Now scientists have calculated the losses and found that more than half of the ice cover in this mountainous country has vanished since the 1970s.

• Ebb & Flow of Greenland’s Glaciers: New Study Could Improve Understanding of Greenland’s Contribution to Sea-level Rise
In northwestern Greenland, glaciers flow from the main ice sheet to the ocean in see-sawing seasonal patterns. The ice generally flows faster in the summer than in winter, and the ends of glaciers, jutting out into the ocean, also advance and [...]

• Historical Satellite Images Reveal Snow is Melting Earlier in Wyoming
A NASA study of a basin in northwestern Wyoming revealed that the snowmelt season in the area is now ending on average about sixteen days earlier than it did from the 1970s through the 1990s.

• Landsat Shows Felling of Tropical Trees Has Soared
The rate at which tropical forests were cut, burned or otherwise lost from the 1990s through the 2000s accelerated by 62 percent, according to a new study which dramatically reverses a previous estimate of a 25 percent slowdown over the same [...]

• Landsat Goes Over The Top: A Long View of the Arctic
On February 11, 2013, the Landsat 8 satellite rocketed into space to extend a four-decade legacy of Earth observations. A few months after launch, we published a composite of images that spanned 9,000 kilometers of land from Russia to South [...]
