The United Kingdom unites with Ireland to make a stand on global warming

Dublin, Ireland:
Many bars and pubs in downtown Dublin took part. The Temple Bar district was abuzz. The Irish Minister of the Environment gave a nationally televised speech to 300,000 viewers at 8.30pm from a major hotel where the lights went off.

Belfast, Northern Ireland:
The Stormont Parliament buildings in Belfast switched off for Earth Hour, ensuring the citizens of Northern Ireland stood with the rest of world in the fight against climate change. 

London, England:
Highlights were Big Ben, Buckingham Palace and Number 10 Downing St going dark, and people gathering to watch Piccadilly Circus darkening for only the fifth time since World War II.

Londoners also joined the WWF team in Trafalgar Square as a giant Hour Glass tracked the hour and reminded all who watched, that while time is ticking, there is still enough time to act, while half a dozen bridges along the River Thames flicked the switch including the iconic Tower Bridge.

Swansea, Wales:
The city of Swansea, Wales plunged into darkness for Earth Hour 2010 when Tintern Abbey, one of the most spectacular ruins in Britain joined other Welsh historical castles like Caernarfon Castle, Conwy Castle and Kidwelly Castle in switching off in the fight against climate change. Other iconic buildings and landmarks that participated in the annual event included Wales Millennium Centre, Newport’s Civic Clock Tower, Pierhead building and Cardiff Harbour Centre. Almost 100 schools were also amongst the nations participants.

Edinburgh, Scotland:

The iconic Edinburgh castle again plunged into darkness, heading up a list of 20 landmarks that went dark for Earth Hour across Scotland. A total of 25 cities and towns confirmed their participation in this year's event reflecting the resolve of the Scottish people to be part of the global climate resolution. 

A unique Earth Hour event in St Andrews saw people come out to play a game of night golf with flourescent clubs and balls, in a novel display of climate action from the city where the sport was invented.
