New York---The Empire State Building dimmed its lights and the Eiffel Tower went dark Saturday as iconic landmarks across the world observed Earth Hour, the global climate change awareness campaign.
The usually glittering nighttime majesty of the Empire State Building was set to "faint sparkle" in New York, while theaters on Broadway also toned down the neon.
In Paris, the Eiffel Tower went black for only five minutes -- due to security reasons -- while nearly 300 other monuments in the City of Light also switched off their lights.
This year's Earth Hour comes as the French capital prepares to host a crucial UN climate conference in December that will bring together the international community to discuss efforts to limit global warming.
Millions of people around the world were taking part in the annual Earth Hour organized by conservation group WWF, with a string of well-known sights plunging into darkness.
In Berlin, activists at the unlit Brandenburg Gate placed candles in paper bags that were lined up to spell out "Save our Climate! Now!" while the Kremlin in Moscow also shed its evening diamonds.
"It's almost like the thing vanished," said Tony Jennings from Earth Hour after standing under the Sydney Harbour Bridge as the lights went off at 8:30 pm (0930 GMT).
In Australia, the initiative this year is focusing on farming, with fears that rising temperatures could ultimately damage the country's ability to produce food.
"In Australia, agriculture is the most vulnerable industry to the impacts of climate change," said national Earth Hour manager for Australia, Anna Rose.
Hong Kong's signature high-rise skyline along the Victoria Harbour was a shadow of itself, with its towering skyscrapers standing dark -- among them were the city's tallest building, the 118-story International Commerce Centre.
In Taiwan, the lights went off on the Taipei 101 tower, the world's tallest building before it was overtaken by Dubai's Burj Khalifa, while in Kuala Lumpur the usually dazzling Petronas Twin Towers were dark.
In neighboring Singapore, all Earth Hour events were cancelled because of the mourning mood following the death of the city-state's founding prime minister Lee Kuan Yew.
