Lights out in 84 countries for Earth Hour 2009

The lights are going down from the Great Pyramids to the Acropolis, the Eiffel Tower to Sears Tower, as more than 2,800 municipalities in 84 countries plan Saturday to mark the second worldwide Earth Hour.


McDonald's will even soften the yellow glow from some Golden Arches as part of the time zone-by-time zone plan to dim nonessential lights between 8:30 p.m. and 9:30 p.m. to highlight global climate change.

"Earth Hour makes a powerful statement that the world is going to solve this problem," said Carter Roberts, chief executive of the World Wildlife Fund, which sponsors Earth Hour.

"Everyone is realizing the enormous effect that climate change will have on them."
Seven times more municipalities have signed on since last year's Earth Hour, which drew participation from 400 cities after Sydney, Australia held a solo event in 2007. Interest has spiked ahead of planned negotiations on a new global warming treaty in Copenhagen, Denmark this December. The last global accord, the Kyoto Protocol, is set to expire in 2012.

U.N. Secretary-General Ban Ki-moon encouraged the convention to reach a fair and effective climate change agreement and promoted Earth Hour participation in a video posted this month on the event's YouTube channel.

"Earth Hour is a way for the citizens of the world to send a clear message," Ban said. "They want action on climate change."
