Lights go dark for Earth Hour to highlight climate change

LONDON, Mar 25 (AP): In Paris, the Eiffel Tower went dark. In London, a kaleidoscope of famous sites switched off their lights - Tower Bridge, Big Ben, Piccadilly Circus, Buckingham Palace, the London Eye.

That scene was repeated over and over across the world on Saturday night: at Sydney's Opera House; at New Delhi's great arch; at Kuala Lumpur's Petronas Towers; at Edinburgh Castle in Scotland; at Berlin's Brandenburg Gate; at St. Basil's Cathedral in Moscow; at the Empire State Building in New York.

It lasted for just an hour and its power is purely symbolic. But in countries around the world, at 8:30 p.m., people switched off their lights for Earth Hour, a global call for international unity on the importance of addressing climate change.
