We can now watch glaciers melt right before our very eyes. Google in conjunction with the University of Washington has released its version of time-lapse mining, a digital sequence of photos of one specific location over time using millions of geo-tagged photographs of popular world landmarks. 

The process works by sourcing images tagged with the same landmark, such as popular streets or natural wonders of the world. Then the images are warped to share the same perspective, and edited for changes in lighting. 

Time-lapse mining will allow for us to see urban and geographical changes in a whole new way, and Google plans to make the source-code for the service publicly available for anyone to be able to create their own lapses.
