Earth Day Doodles

Today's Doodle on the Google homepage features animated time-lapse imagery, providing evidence of the impact of climate change. In honor of Earth Day 2022 Google is displaying four different animated GIF's, each one showing how global heating is effecting one of four different locations around the world. 

If you use Google search today you will see one of these four animated satellite time-lapse clips instead of the Google logo. The four different images will be rotated throughout the day. The timelapse shown at the top of this post uses satellite imagery from 1986 to 2020 to show the retreat of the Kilimanjaro summit glacier. Other timelapses show evidence of coral bleaching on the Great Barrier reef, deforestation in Germany, and glacier retreat in Greenland.

The four animated Google Doodle timelapse images were created using Google Earth Timelapse. Google's Timelapse site includes many other examples of timelapse images showing how the Earth has changed over time. It also gives you access to a global interactive map featuring historical satellite imagery from the past 37 years. It is therefore possible to use Google Earth Timelapse to create your own animated timelapse image for any location in the world.

Earth Day is held every year on April 22nd to help promote environmental protection. The official Earth Day website includes news of events, information on climate change, and advice on how you can help protect the planet and contribute to stopping climate change.

You can view all four Earth Day Google Doodle timelapses on the Google Doodle Earth Day page.
