Google Earth has launched a time-lapse feature that allows users to wind back the clock 37 years and see how the world has changed over the years.
Google Earth uses similar technology to the widely used Maps product, but is more focused on geology and exploration than public transport and directions.
Users can access the tool in a web browser, and the feature comes with some pre-packaged virtual tours of an Alaskan glacier melting over the years or forest protection efforts in Brazil.
Google is heavily marketing the tool as a way to raise awareness of climate change and other environmental issues.
