Ever wanted to look at the way that Earth has changed over the years? Google has put together an interesting Timelapse series doing just that. In the blog post, the company states that they worked with the U.S. Geological Survey (USGS), NASA and TIME–continuing to relay that these were created from millions of images and trillions of pixels.

“…we sifted through 2,068,467 images—a total of 909 terabytes of data—to find the highest-quality pixels (e.g., those without clouds), for every year since 1984 and for every spot on Earth. We then compiled these into enormous planetary images, 1.78 terapixels each, one for each year.”

While most timelapses take place over a period of a couple of hours, this one goes for years. It clearly shows the erosion of coasts, the movement of clouds, deforestation, etc.

And when put this way, Google has created a scary but realistic sense of exactly what we’re doing to our environment.
