A 24 hour-long wave of darkness will sweep around the globe as people and corporations turn out the lights from 8:30 to 9:30 pm local time on Saturday, March 27 to mark Earth Hour - sponsored by the World Wildlife Fund to promote effective climate change action.
New Zealand's Chatham Islands will be the first place to start Earth Hour - the South Pacific island of Samoa will end the sweep 24 hours later.
Calling it "the greatest global action on climate change ever witnessed," WWF says this year 3,100 cities in 121 countries on all seven continents have confirmed that they will turn off their lights for Earth Hour.
"Earth Hour brings together cities, communities, businesses and individuals on the journey to positive action on climate change," said Earth Hour Executive Director Andy Ridley.
"Simple individual actions such as turning off a light can amount to a collective and profound impact on energy conservation," said Michael Sole, who heads the Florida Department of Environmental Protection. "Earth Hour reminds us of the harmful effects of climate change, and how worldwide action can alleviate this issue both in the present and for the future."
U.S. landmarks such as Mount Rushmore in South Dakota, St. Louis' Gateway Arch, Sea World in Orlando, The Strip in Las Vegas, New York's Empire State Building, Washington DC's National Cathedral, and the Space Needle in Seattle are among the hundreds of sites that will turn off non-essential lighting for the hour.
In the UK, intense lobbying by Members of Parliament has resulted in Big Ben and the Houses of Parliament pledging to switch off their lights for Earth Hour.
A candlelit vigil with music will take place at one of the world's largest waterfalls, Victoria Falls, on the border between the African nations of Zambia and Zimbabwe. Organized by the NGO Environment Africa the event will be attended by hundreds of schoolchildren, community members and dignitaries to recognize what organizers call Earth Hour's "unifying global message of hope and action for a better healthier planet."
Other world icons observing Earth Hour include the Eiffel Tower in Paris, New York's Empire State Building, the Trevi Fountain in Rome, the Sydney Opera House, Cape Town's Table Mountain, Rio's Christ the Redeemer statue, the Hiroshima Peace Memorial, and the world's tallest building, Burj Khalifa in Dubai, United Arab Emirates.
Earth Hour originated in Sydney, Australia three years ago, when more than two million residents turned off their lights for one hour. Last year, nearly one billion people jointly participated in Earth Hour.
Entitled "Appetite for Change," the survey, published in January, shows that 84 percent of the corporate executives who responded believe global warming will change the way they do business over the next two to three years.
"On past experience, participation is more than what we know about before the event, particularly when it comes to cities and communities," said Earth Hour's Ridley. "We are already overwhelmed by how the people of the world have committed to Earth Hour 2010 but we won't know the full extent of its impact until after it takes place across the globe."
