Google Earth’s New Timelapse Feature Shows 4 Decades of Climate Change
LOS ANGELES – From the changing forests of Oregon to the changing glaciers of Greenland, a new feature in Google Earth illustrates nearly four decades of climate change from endless perspectives.
The feature, Timelapse, provides a global, zoomable image time-lapse video from various locations on Earth from 1984 to 2020 and provides visual evidence of how climate and human behaviors have changed regions of the Earth’s surface.
“Since the launch of Google Earth, we have focused on creating a 3D replica of the world that reflects our planet in beautiful detail with features that entertain and empower everyone to create. positive change, “Rebecca Moore, director of Google Earth, Earth Engine and Outreach, said in a blog post titled”Time flies in Google Earth’s biggest update in years. “
Using Earth Engine, Google combined millions of satellite images from the past decades collected by five different satellites.
“In the biggest update to Google Earth since 2017, you can now see our planet in a whole new dimension: time. Timelapse in Google Earth, 24 million satellite photos from the last 37 years have been compiled in an interactive 4D experience. Now anyone can watch the time unfold and witness nearly four decades of planetary change, ”said Moore.
According to Google, the majority of the images come from Landsat, a joint USGS-NASA Earth observation program that has observed the Earth since the 1970s. Since 2015, Google has combined the Landsat images with the images from the Sentinel-2 mission, which is part of the Copernicus Earth Observation Program of the European Union and the European Space Agency.

Additionally, Google has partnered with Carnegie Mellon University’s CREATE Lab to show how human impact is changing the Earth’s forests and waterways, and how cities are developing around the world.
“Our planet has experienced rapid environmental change over the past half century – more than at any time in human history,” Moore said. “With Timelapse in Google Earth, we have a clearer picture of our evolving planet at our fingertips – an image that shows not only the problems, but the solutions as well, as well as fascinatingly beautiful natural phenomena unfolding. over decades. “
