More than 6,950 cities and towns in 152 countries and territories switched off their lights for Earth Hour 2012, sending a powerful message for action to save the planet. This year marked the continuation of the movement’s commitment to going Beyond the Hour, with more than 200,000 individuals accepting I Will If You Will challenges on YouTube to turn their symbolic action for the planet into an ongoing commitment to a sustainable future.

Global warming is the greatest threat facing our planet today. A warming planet alters weather patterns, water supplies, seasonal growth for plants and a sustainable way of life for us, and the world’s wildlife. Climate change has already started, but it’s not too late to take action. There’s still time for us all to be part of the solution.

Earth Hour happens because of the committed teams around the world that work tirelessly to get lights switched off. Coordinating their tremendous efforts is a small team of Sydney-siders – the Earth Hour Global Team.
