Earth-hour

ATLANTA - Who turned out the lights? A global campaign to raise awareness on climate change has reached the United States.

LONDON - Europe's best known landmarks - including the Eiffel Tower, Big Ben and Rome's Colosseum - fell dark Saturday, following Sydney's Opera House and Beijing's Forbidden City in joining a global climate change protest, as lights were switched off across the world to mark the Earth Hour event.

SYDNEY - The white-shelled roof of the Sydney Opera House fell dark Saturday night, one of the first landmarks to turn out the lights in an hour-long gesture to be repeated by millions of people around the world who are calling for a binding pact to cut greenhouse gas emissions.
