Earth Hour is an initiative by the WWF to encourage people to “vote” for the Earth and against detrimental man-made climate change, particular that caused by overuse of fossil fuels. What time is Earth Hour in your time-zone?
So, Earth Hour is not a global simultaneous event but begins in each part of the world as the local time comes to 8:30pm. To reiterate in each time-zone you should mark Earth Hour at a different time with respect to GMT/EST (or whichever standard time-zone you prefer) simply as the time on your normal clock comes to 8:30pm.
Read about it. Tell your family, friends, acquaintances, colleagues, neighbours, petition your local council … and then join with everyone in turning off your lights on 28 March at half-past-eight.
A little about Earth Hour from the WWF web pages:
More than 1,500 cities and towns in over 80 countries […] Landmarks from Nelson’s Column and the Wembley Arch in London, to the Millennium Stadium in Cardiff, the entire quayside in Newcastle and the Forth Bridge between Edinburgh and Fife are also committed to taking part.
“WWF’s Earth Hour is set to be the world’s biggest ever climate change event, and it will send an incredibly powerful message to global leaders that, in order to avoid its worst impacts, they need to take action to tackle climate change now,” said Colin Butfield, Head of Campaigns at WWF-UK. […]
WWF hopes that the millions of people taking part in Earth Hour will help to convince governments across the world that they must agree to take effective action to tackle climate change when they meet at the UN Climate Summit in Copenhagen, in December.
It may not be worth buying a new t-shirt just for Earth Hour so we recommend buying one anyway but wearing it at other times too ;0)
