The hour the world unites in a stand against global warming
Earth Hour is a WWF initiative where YOU can show your support for action on climate change by turning off your lights for one hour.
WWF’s Earth Hour is an inspiring message of hope and action – a global demonstration about climate change.
At 8.30pm on 27 March 2010, over 4000 cities and towns across the world will turn off their lights for one hour – Earth Hour – sending a powerful message that it’s possible to take action on global warming. It will let world leaders know the world is still watching, following the UN Climate Summit in Copenhagen in 2009 which leaves room for a better deal, we believe in not letting the spirits die.
