Google Earth adds time lapse video to depict climate change

by Mary Sewell

SAN RAMON, Calif. — The Google Earth app is adding a new video feature that draws upon nearly four decades of satellite imagery to vividly illustrate how climate change has affected glaciers, beaches, forests, and other places worldwide. The tool unveiled Thursday is rolling out in what is being billed

as the most significant update to Google Earth in five years. Google says it undertook the complex project in partnership with several government agencies, including NASA in the U.S. and its European counterpart, hoping to help a mass audience grasp the sometimes abstract concept of climate change in more concrete terms through its free Earth app.

Cornell University climate scientist Natalie Mahowald believes that the mission may be accomplished.

changes many people’s minds about the scale of the impact of humans on the environment.” This isn’t the first time time-lapse satellite imagery has demonstrated how parts of the world are changing before our eyes due to a changing climate. Most scientists agree that climate change is being driven by pollution primarily produced by humans.

But earlier images have primarily focused on melting glaciers. They haven’t been widely available on an already popular app like Google Earth, which can be downloaded on more than 3 billion smartphones now in use worldwide. Google is promising that people will be able to see a time-lapse presentation of just about anywhere they want to search. The feature also includes a storytelling mode highlighting 800

different places on the planet in both 2D and 3D formats. Those videos also will be available on Google’s YouTube video site, a service more widely used than the Earth app. According to Google, the feature was created from 24 million satellite images taken every year from 1984 to 2020 and provided by NASA, the U.S. Geological Survey, and the European Union. The time-lapse technology was created with the help of Carnegie Mellon University.

Google plans to update the time-lapse imagery at least once a year.
