Google Earth adds time lapse video to depict climate change


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 around the world.


The tool unveiled Thursday is rolling out in what is being billed as the biggest update to Google Earth in five years.


Alphabet’s Google GOOGL, +1.93% says it undertook the complex project in partnership with several government agencies, including NASA in the U.S. and its European counterpart, in hopes that it will help a mass audience grasp the sometimes abstract concept of climate change in more tangible terms through its free Earth app.


“Trying to get people to understand the scope of the climate change and the land use problem is so difficult because of the long time and spatial scales.


But earlier images have mostly focused on melting glaciers and haven’t been widely available on an already popular app like Google Earth, which can be downloaded on most of the more than 3 billion smartphones now in use around the world.


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, according to Google.
