Computer scientist Rebecca Moore and her team at Google created Google Earth Engine to enable global-scale data-mining.

Earth Engine brings together trillions of scientific measurements dating back over 40 years, and Google gives researchers, scientists, and nations the tools to analyze this data to detect changes and trends.

Using Landsat satellite imagery from 1984 to 2012, the team was able to create half a dozen incredible time-lapse maps that show areas of particularly dynamic change.

The result is jarring.
