A Terrifying, Fascinating Timelapse of 30 Years of Human Impact on Earth - Emily Badger A new interactive project from Google, NASA and the US Geological Survey. Since the 1970s, NASA and the U.S. Geological Survey have been amassing satellite images of every inch of our planet as part of the Landsat program. If you could thumb through these historic pictures as if in a flip book, they would show stunning change across the earth's surface, in both our natural environments and our man-made ones. Landsat images taken between 1984 and 2012 have been converted into a seamless, navigable animation built from millions of satellite photos.

The above image shows Dubai in 2011.
