Are you taking part? At 8:30pm tonight local time I will be switching off all lights and electrical equipment for 1 hour.
Earth hour started in Sydney in 2007 when 2.2million individuals and more than 2,000 businesses turned their lights off for 1 hour to take a stand against climate change. In 2010 a record 128 territories and countries joined the global display of climate action. To read more about Earth Hour and to sign up to say that you will be taking part you can visit the WWF website here.
