Sydney (AFP) - From Sydney's Opera House to New York's Empire State Building and Paris's Eiffel tower, landmarks worldwide dimmed their lights Saturday for the 10th edition of the Earth Hour campaign against climate change.

Millions of people from 178 countries and territories were expected to take part in WWF's Earth Hour this year, organisers said, with monuments and buildings such as Berlin's Brandenburg Gate plunging into darkness for 60 minutes from 8:30 pm local time.
