This Earth Day, the search engine is dedicating its logo to how badly we are messing up the planet. It's actually kind of cool. There are four different GIFs that show the dramatic changes caused by climate change.
From Australia's Great Barrier Reef, you'll see footage of bright corals losing their color. Corals have a symbiotic relationship with the algae in their tissues. Under stress, corals lose their algae in a depressing phenomenon called bleaching.
The Great Barrier Reef has had a sixth mass bleaching event this year, according to the marine park's authority in March. It is one of the consequences of the world warming. 99 percent of the world's reefs could be wiped out by one more degree of warming. There was another mass bleaching event in 2016 and the time-lapse on the doodle shows it. The images were taken by The Ocean Agency.
The glaciers from the summit of Mount Kilimanjaro and Sermersooq are shown in two other GIFs. One of the three peaks in Africa topped with glaciers is Kilimanjaro. The glaciers could disappear within a couple of decades if they continue to retreat.
There is forest destruction in Elend, Germany. There are gray carcasses of dead trees here that have earned parts of Harz National Park the name Harzer Silberwald, or Harz Silver Forest. The trees were weakened by the dry spell and are more vulnerable to attack from bark beetles.
Climate-denying ads that slipped past its policy banning such misinformation have come under scrutiny from advocacy groups. Clicking on today's doodle will lead you to information about the climate crisis.
