From an Antarctic research base and the Great Pyramids of Egypt to the Empire State Building in New York and the Sears Tower in Chicago, illuminated patches of the globe went dark for Earth Hour, a campaign to highlight the threat of climate change.
Time zone by time zone, nearly 4,000 cities and towns in 88 countries joined the event sponsored by the World Wildlife Fund to dim nonessential lights from 8.30pm to 9.30pm. The campaign began in Australia in 2007 and last year grew to 400 cities worldwide.
Organisers initially worried enthusiasm this year would wane with the world focused on the global economic crisis, said Earth Hour executive director Andy Ridley. But he said it apparently had the opposite effect.
“Earth Hour has always been a positive campaign; it’s always around street parties, not street protests, it’s the idea of hope, not despair. And I think that’s something that’s been incredibly important this year because there is so much despair around,” he said.
Crowds in Times Square watched as many of the massive billboards, including the giant Coca-Cola display, darkened. Steps away, the Majestic Theatre marquee at the home of The Phantom of the Opera went dark, along with the marquees at other Broadway shows.
Mikel Rouse, 52, a composer who lives and works nearby came to watch what he called “the centre of the universe” dim its lights.
“C’mon, is it really necessary? ... All this ridiculous advertising ... all this corporate advertising taking up all that energy seems to be a waste,” Mr Rouse said.
In Chicago, one of 10 US Earth Hour flagship cities, a small crowd braved a cold rain to count down as Governor Pat Quinn flipped a four-foot-tall mock light switch that organisers had to brace against high winds. A second later, the buildings behind him went dark.
“I don’t see why people shouldn’t always turn off the lights,” said 15-year-old Chicagoan Tyler Oria, who was among those gathered.
More than 200 buildings pledged to go dark in the city, including shops along the Magnificent Mile.
“No matter what your individual beliefs are about climate change, energy efficiency is something everyone can understand in this economic environment,” said WWF managing director Darron Collins, who helped Chicago officials organise for the night.
The Smithsonian Castle, World Bank, National Cathedral and Howard University were among several buildings that went dark for an hour in the nation’s capital.
“This was the first year that Washington, DC, became an official Earth Hour city,” said Leslie Aun, WWF spokeswoman.
In the Chilean capital of Santiago, lights were turned off at banks, the city’s communications tower and several government buildings, including the Presidential Palace where President Michelle Bachelet hosted a dinner for US Vice President Joe Biden.
The leaders and dozens of guests dinned at candlelight.
In Mexico City, the city government and business owners turned off all “nonessential” lights at more than 100 buildings, including 31 city buildings and monuments and 17 hotels.
In San Francisco, lights on landmarks like the Golden Gate Bridge were set to be turned off, along with the city’s well-known Ghirardelli Square sign.
The Las Vegas Strip turned down its glitz by extinguishing pockets of neon outside casinos while some witnesses alerted their friends on Twitter.
UN Secretary Ban Ki-moon called Earth Hour “a way for the citizens of the world to send a clear message: They want action on climate change”.
An agreement to replace the Kyoto Protocol, which expires in 2012, is supposed to be reached in Copenhagen, Denmark, this December, and environmentalists’ sense of urgency has spurred interest in this year’s Earth Hour.
In Bonn, WWF activists held a candlelit cocktail party on the eve of a UN climate change meeting, the first in a series of talks leading up to Copenhagen.
China participated for the first time, cutting the lights at Beijing’s Bird’s Nest Stadium and Water Cube, the most prominent 2008 Olympic venues. In Bangkok, the prime minister switched off the lights on Khao San Road, a haven for budget travellers packed with bars and outdoor cafes.
In Rio de Janeiro, the Christ the Redeemer statue that watches over the city of six million was darkened, along with the beachfront of the famed Copacabana and a few other local sites.
Earth Hour organisers say there’s no uniform way to measure how much energy is saved worldwide.
