In 2009, at 8.30pm on March 28, people around the world will turn their lights off for one hour – Earth Hour. We’re aiming to reach one billion people, more than 1000 cities, all joining together in a global effort to show that its possible to take action on global warming.

This event is part of WWF’s international campaign to convince governments across the world to agree a strong global deal to tackle climate change, when they meet at the UN climate summit in Copenhagen, in December 2009.

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.

Earth Hour provides a united global message to every individual, every business and every community that climate change affects us all and to take responsibility in working towards a sustainable future.

Join us for Earth Hour 2009, turn off your lights at 8.30pm Saturday 28 March and sign-up here at earthhour.org/Australia

Earth Hour is a message of hope and a message of action. Everyone can make a difference.
