 The Eiffel Tower is to turn its famous night-time illuminations off for five minutes on Thursday to help draw attention to energy consumption and the environment on the eve of the release of a UN report on climate change. The 336 projectors that light up the tower at night will be switched off between 7:55 pm and 8:00 pm (1855-1900 GMT), a spokeswoman for SETE, the company that operates the 19th century metal tower in central Paris said. The Eiffel Tower's illuminations are one of the most notable features of the French capital's skyline and account for 9 percent of the 7,000 megawatts consumed hourly by the structure. Earlier this week, environmental campaigners from Greenpeace hung a banner showing a giant thermometer from the Eiffel Tower to publicise the global warming issue. A UN report on climate change to be released officially on Friday in Paris projects a big rise in temperatures and warns of heatwaves, floods, droughts and rising sea levels linked to greenhouse gases, released mainly by the use of fossil fuels. The switch off is part of a campaign organised in conjunction with the Paris mayor's office to highlight the impact of energy consumption on global warming.
