Earth Hour 2010 — Lights Out for Climate Change

Lights across the globe will go out Saturday night as part of Earth Hour. The yearly event encourages people to save energy and resources, if only for an hour.

Earth Hour occurs at 8:30 p.m. local time and major world landmarks will go dark, including the Eiffel Tower, the Empire State Building and the Sydney Opera House.

The World Wide Fund for Nature is coordinating the event and has provided activities for families to occupy their time when the lights go out.

Last year, 87 countries participated in the climate change initiative, which is a vast improvement from when the event first launched in Australia back in 2007.
