Earth Hour: 60 Minutes for the Planet

On March 24th at 8:30pm, millions of people across the globe will be strolling past buildings like the Empire State Building or shopping in places like Ghirardelli Square when they’ll suddenly find themselves in the dark. For one hour, the world will turn out its lights and be united in its support for climate action.

This annual global movement, coined Earth Hour, is a moment for landmarks, businesses, governments, and individuals at home to turn off non-essential lights and amplify their concerns for our planet. And it’s more important than ever that we call for action to limit carbon emissions driving climate change and prepare communities for a rapidly warming world.

2017 was the third warmest year on record and the costliest weather year the US has ever experienced, according to the National Oceanic and Atmospheric Administration. Floods, tornadoes, hurricanes, droughts, fires and freezes resulted in $306 billion of damages, wreaking havoc on ecosystems and people across the US.

Increasingly frequent and severe weather events are just one of the ways that climate change is impacting all of us today, and it will take all of us to address the problem. Earth Hour is a time to recognize that fact, and to raise awareness that helps push the world toward the next phase of climate action.

Here at home, a new generation of leaders from across America is stepping up. Businesses are setting more aggressive renewable energy targets, city governments are building infrastructure that can weather greater storms, universities are training the next generation of climate leaders – and these are just a few examples.

The importance of combatting climate change and the need to act now cannot go unnoticed. That’s why each year thousands of cities and organizations and millions of people around the world commit to Earth Hour. While participating in 2018 can be as simple as turning off the lights for 60 minutes, many will go beyond the hour and take further action.

Companies will use Earth Hour to highlight their climate commitments and build larger employee engagement around climate action. Local leaders will coordinate Earth Hour events from hikes to yoga classes that bring people together. Individuals will participate at home with friends and family, further helping raise awareness. Moreover, the world will take to social media to show their solidarity for a cause that truly impacts everyone on the planet.

No matter where you are or what you’re doing on March 24th, World Wildlife Fund hopes you’ll find a way to join the Earth Hour movement at 8:30pm local time. With a little work from everyone, we can help avoid the worst impacts of climate change and protect our planet for future generations.
