Each year, individuals, governments and businesses around the globe are encouraged to switch off their lights for one hour - Earth Hour. Earth Hour is an Australian initiative that began in Sydney in 2007 to help combat climate change. In 2008, Earth Hour involved between 50 and 100 million people in 370 cities and towns around the world, including Chicago, Toronto, Copenhagen, Dublin, Atlanta and Bangkok. Earth Hour 2009 takes place on Saturday 28 March. By turning off our lights, we can send a message to the world's leaders that strong action needs to be taken to combat climate change.
Switch off your lights for Earth Hour 2009 on Saturday 28 March. For a list of Earth Hour times around the globe, visit earthhour.org You can also see a countdown to your local Earth Hour when you hold the globe in your hands.
Remember to get your family and friends involved, too. You can spread the word by taking a screenshot of you holding the globe and sending it on to others.
WWF is the world's largest and most experienced independent conservation organisation and is responsible for Earth Hour. With close to five million supporters and a global network active in more than 100 countries, WWF's mission is to stop the degradation of the planet's natural environment. This is achieved by working on the ground with local communities, and in partnership with government and industry, using the best possible science to advocate change and effective conservation policy.
A two degree rise in average global surface temperature will have severe social, economic and environmental impacts: 3.1 billion people will suffer serious water shortages; 180 million people will be affected by sea level rise; and approximately 25% of species extinct in present habitat. The world's leading climate scientists believe that we must reduce greenhouse gas pollution by 25%-40% below 1990 levels if we are to avoid the worst impacts of climate change.
