Google Earth’s Big Eye-Opener on Climate Change
Watch the glaciers recede before your eyes. Google Earth has released an update to its timelapse feature, with data now going back to 1984 and higher-resolution maps to show the evolution of the globe from above. You can watch rivers reroute, islands disappear and glaciers roll swiftly back, using images collected from two new satellites, Landsat 8 and Sentinel-2. The tool could be useful in classrooms — not just for studying hometown growth and local environmental changes, but as a stark illustration of climate change in action.
