The power of Google Earth is once again on display as a new feature highlights the drastic changes to our planet in the last 37 years. A series of timelapse videos available in Google Earth focuses on areas of extreme change from 1985 through to today, including changes to forests, glaciers, rivers, cities and more.
The feature offers a series of stories and featured locations that show some of the most interesting locations, including the forests of Brazil, the glaciers of Alaska and the expansions of megacities such as Beijing and Dubai. You can also start typing in the search to discover other locations. Hong Kong airport being built in the sea, for instance, is really impressive.
Available on both the app and web versions of Google Earth, the timelapse uses over 15 million satellite images taken over the past four decades, collected by five different satellites. One thing that does become obvious, when you zoom right in, is that early satellite images were much less clear than those of today, so as well as the timelapse showing the changing landscape, it also gets better quality as it moves to modern-day.

But, as Rebecca Moore, director of Google Earth said in a press call, “it’s not about zooming in, it’s about zooming out.” This timelapse allows you to take a step back and see the large picture of how much things have changed across the globe.
Google Earth first offered timelapse views back in 2013, showing changes from 1984 to 2012 and provided an update in 2016. However, these were all in 2D. The new timelapse videos all show in full 3D, allowing you to pan and tilt around the scene as you desire.
As the big brother to Google Maps, Google Earth has always been a hugely powerful tool that helps to educate, inform and amaze. We could get lost for hours exploring new places on Google Earth and rediscovering old haunts. At a time when international travel is virtually impossible, it’s the closest we can get.
While some of the urban changes are impressive, others are more frightening and show just how much damage has been done to our natural world. Each of the stories comes with a description that explains and educates on the causes of the changes. We highly recommend spending some time reading and exploring.
