Today on the occasion of Earth Day, each time you visit the Google homepage, you'll come across one of five 'doodles' created by Google.

"Earth Day, celebrated annually on April 22, may be the one day that transcends culture, language, and tradition," says Google's doodle-er Sophie Diao.

This Earth Day is particularly important because as many as 170 countries are expected to sign the Paris Agreement on climate change in a symbolic triumph for a landmark deal that once seemed unlikely but now appears on track to enter into force years ahead of schedule.

As for Google, the search giant that always honours noted events, celebrations and personalities from across the globe, has been 'doodling' Earth Day for a while now.

Here are some of its breathtaking doodles:
