On Saturday night WWF estimates that over a billion people across the world united in switching off their lights for one hour to show they care about climate change.
Earth Hour's success is down to you - individuals and families switching off at home, or companies large and small, local government, schools and community groups. And of course thanks to all WWF's regular supporters and volunteers.
The statistics are still coming in, but the latest news is that over 4,000 cities and towns in 126 countries took part in WWF's Earth Hour 2010. Global landmarks switching off included Big Ben and the Palace of Westminster, the Eiffel Tower in Paris, the Great Pyramids, Rome's Coliseum and Forbidden City in China.
In the UK, other landmarks included Buckingham Palace, Piccadilly Circus, Tower Bridge, the National Gallery and National Theatre and Wembley Stadium Arch in London; the Senedd, The Wales Millennium Centre, and Millennium Stadium in Cardiff; Stormont, City Hall and the Wheel in Belfast, Edinburgh Castle, the Scottish Parliament, Wallace Monument and the Falkirk Wheel, to name just a few.
Earth Hour was all about spreading the message that we care about our world, and we received great support from global and UK press, TV, radio and the online community.
A big thank-you from everyone at WWF for signing up and taking part in this years' event. It's been an enormous success - just take a look at the highlights, news, photos and film coverage from the night at

We'll be back in touch shortly after Easter with a full round-up of the event and more news from WWF.
