Google Earth feature depicts climate change

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 affected 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 five years. Google 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.

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

“This is amazing,” she told The Associated Press after watching a preview of the new feature. “Trying to get people to understand the scope of the climate

change and the land use problem is so difficult because of the long time and spatial scales. I would not be surprised if this one bit of software changes many people’s minds about the scale of the impact of humans on the environmen­t.”

This isn’t the first time time-lapse satellite imagery has been used to demonstrat­e how parts of the world are changing due to a changing climate. Most scientists agree that climate change is being driven by pollution primarily produced by humans.

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

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 different places on the planet in both 2D and 3D formats. Those videos also will be available on Google’s Youtube video site.

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. The time-lapse technology was created with the help of Carnegie Mellon University.

Google plans to update the timelapse imagery at least once a year.
