Google Doodle said: “Today’s annual Earth Day Doodle addresses one of the most pressing topics of our time: climate change.
“Using real time-lapse imagery from Google Earth Timelapse and other sources, the Doodle shows the impact of climate change across four different locales around our planet.”
Google encourages users to “Stay tuned throughout the day to view these scenes, each remaining on the homepage for several hours at a time.”
Google Earth images from Mount Kilimanjaro, taken every December from 1986 until 2020, show glacier retreat at the summit, while glacier retreat in Greenland has been documented annually from 2000 to 2020.
The images from the Great Barrier Reef show coral bleaching on Lizard Island from March until May 2016, while footage from Germany, taken every December from 1995 to 2020, shows how the Harz Forests are being destroyed by bark beetle infestation, caused by rising temperatures and severe drought.
Google says: “Acting now and together to live more sustainably is necessary to avoid the worst effects of climate change,” and encourages users to use the search engine to “learn more about climate change and how you can take action.”
Earth Day 2022
What is Earth Day?
Earth Day has been observed annually on April 22 since its inception in 1970.
Earth Day’s mission is “to diversify, educate and activate the environmental movement worldwide,” according to the organisation’s website.
It is a day to support environmental protection and demand action against climate change.
The theme of Earth Day 2022 is “Invest in Our Planet” and the organisation will host the Earth Day Climate Action Summit, where its leaders will share solutions that will help deliver the greenhouse gas reductions needed by 2030 to meet the Paris Agreement.
