Cities around the world turn off lights to mark Earth Hour

Updated : March 31, 2019 08:08 AM IST

Cities around the world marked Earth Hour by turning off the lights in a call for global action on climate change. Earth Hour was observed from 8:30 pm to 9:30 pm., worldwide. Since 2007, Earth Hour has been a movement to bring awareness to climate change, while promoting action to preserve the climate and environment. The 13th edition of Earth Hour saw 24 global landmarks -- from the Sydney Opera House to Dubai's Burj Khalifa -- dim their lights.
