Comhairle nan Eilean Siar Council has already agreed to switch off and support WWF's Earth Hour and the WWF Panda called on all residents to join in.

At 8.30pm on Saturday, March 27 hundreds of council-owed buildings and monuments across Scotland will join thousands of others around the world in falling dark for 60 minutes in a graphic demonstration of support for people and wildlife threatened by climate change. Across the globe over 2,000 towns, cities and municipalities in over 100 countries are also taking part.

In Scotland this year's event is already on course to be a record breaker with 25 of our 32 local authorities set to participate in the world's biggest public event in support of action on climate change.

Dr Richard Dixon, Director of WWF Scotland said: "WWF's Earth Hour has once again captured the public's imagination both here and around the world. A record number of countries have signed up already, smashing last year's total. Here in Scotland 27 of out of 32 local authorities have also given it their backing.

"Climate change is one of the most serious threats facing people and nature. Last year, world leaders missed a key opportunity to agree a global climate deal in Copenhagen. By switching off your lights on Saturday 27 March at 8.30pm you will be joining hundreds of millions around the world in sending a strong call to action on climate to world leaders."

The WWF Panda added: "It was great to visit Stornoway and to see how enthusiastic people are about WWF's Earth Hour. But, it is not too late to sign-up. Simply visit the WWF Scotland website and add your name and then take part on Saturday 27 March. By doing so you will be showing you care about the people and wildlife affected by climate change."
