Famous monuments all over the world
Cities around the world turned off their lights for an hour on Saturday as part of the World Wide Fund for Nature's (WWF)annual Earth Hour campaign.
Millions of people have taken part in the 10th annual climate awareness-raising event, which has grown significantly since it began in Sydney, Australia, in 2007.
"From one city it has now grown to over 178 countries and territories and over 7, 000 cities. So we couldn't be happier about how millions of people across the world are coming together for climate action, " Earth Hour's global executive director Siddarth Das told news agency AFP via telephone.
Das added that support for climate action is on the rise in the wake of theglobal climate talks in Paris
last year. The so-called Paris Agreement seeks to limit global warming to "well below" 2 degrees Celsius (3.6 degrees Fahrenheit) over pre-industrial levels, with a more ambitious target of 1.5C if possible.
More than 350 monuments such as the Eiffel Tower, Taipei 101, the Empire State Building, and the Brandenburg Gate were set to go dark for 60 minutes at 8:30 p.m. local time on Saturday.
World celebrates Earth Hour
Cities on Australia's east coast were some of the first to turn off their lights on Saturday. Sydney's famous Opera House and Harbor Bridge, usually brightly lit, went dark for 60 minutes for the 10th year in a row.
Prior to lights going out in Singapore, hundreds of people stood in a yoga tree pose in an attempt to break a world record:
Beijing darkened its famous "Bird's Nest" national stadium, while municipal government officials announced that the city's conservation slogan would be: "Consume less, consume wisely."
Supporters around the world will turn off lights in their homes and attend local climate change events as part of the worldwide show of solidarity with Mother Nature.
All of the stars - by Oaker Min, Singapore
"Jurong Island at the far south of Singapore is an industrial estate. It houses production facilities of many global chemical and energy corporations. A group of friends and I were exploring southern Singapore in Labrador Park and saw a huge flare being emitted from the island that night. I was stunned at the sight of this and decided to take a photo of it."

"This is on the shore of lake Nahimovskoya, north of St. Petersburg. It was spring and the lake started melting, the waves tossing pieces of ice onto the shore. Suddenly I found this piece with a hole in the center of it, and decided to take a shot."

In the face of disaster - Winner. By Joel S. Mataro, Philippines
Our winner: "Taken minutes after the onslaught of typhoon Glenda in 2014, the photo shows the wrath of water and wind. The town of Malvar, in this part of Batangas, Philippines is seldom visited by typhoons; stories of destroyed houses or devastated crops had been unheard and unseen of here for years. But with climate change, these kinds of images are set to become more frequent."
