Earth Hour organizer World Wildlife Fund (WWF) said great strides had been made to highlight the dire condition of the planet. At the time, Siddarth Das, executive director of Earth Hour Global, said in a statement: “Earth Hour reminds us that while people are on the frontlines of climate change, they are also our first-line of defence”.

“When individuals unite, the power of the collective can create a massive impact as we have seen with Earth Hour observations over the past decade”, he added.

It has since grown to a worldwide movement.

The world will celebrate Earth Hour on Saturday night by switching off lights and going “dark” for one hour to encourage participation in fighting climate change.

“I agree with the concept, 100 percent”, said student Ed Gellert, 24, in Sydney.

The Environment and Protected Areas Authority (EPAA) will also host a public event starting at 5.30pm on the Al Majaz water front. In this edition, at 20:30 local time, all kinds of activities will take place in other cities: a concert with candles in Lisbon, tree planting in Tanzania, and as it is traditional, many monuments will turn off its lights: the Empire State Building, the Egyptian pyramids, the Kremlin, the Acropolis of Athens, the Alhambra of Granada, etc. “As part of our commitment, DEWA will implement, for the second consecutive year, its Carbon Neutral Emissions following last year’s successful zero-carbon Earth Hour celebrations”.

Nations agreed in Paris in 2015 to limit average global warming to two degrees Celsius (3.6 degrees Fahrenheit) over pre-industrial temperatures.

“Humanity today is facing unprecedented levels of climate change that threaten both present and future generations”.

Earth Hour does not collect global statistics on the energy conserved during the 60-minute blackout, with the event having a more symbolic intent.
