U.S. releases unclassified spy images of Arctic ice

WASHINGTON (Reuters)

Some 700 images show swatches of sea ice from six sites around the Arctic Ocean, with an additional 500 images of 22 sites in the United States. The images can be seen online at http://gfl.usgs.gov/.

Changes in the Arctic affect global climate, since the Arctic region acts as an “air conditioner” for the planet.
