The lights are going down from the Great Pyramids to the Acropolis, the Eiffel Tower to the Sears Tower, as more than 2,800 municipalities in 84 countries plan today to mark the second worldwide Earth Hour.
McDonald’s will even soften the yellow glow from some Golden Arches as part of the time zone-by-time zone plan to dim nonessential lights between 8:30pm and 9:30pm to highlight global climate change.
“Earth Hour makes a powerful statement that the world is going to solve this problem,” said Carter Roberts, chief executive of the World Wildlife Fund (WWF), which sponsors Earth Hour. “Everyone is realizing the enormous effect that climate change will have on them.”
Seven times more municipalities have signed on since last year’s Earth Hour, which drew participation from 400 cities after Sydney, Australia, held a solo event in 2007. Interest has spiked ahead of planned negotiations on a new global warming treaty in Copenhagen, Denmark, this December. The last global accord, the Kyoto Protocol, is set to expire in 2012.
UN Secretary-General Ban Ki-moon encouraged the convention to reach a fair and effective climate change agreement and promoted Earth Hour participation in a video posted this month on the event’s YouTube channel.
“Earth Hour is a way for the citizens of the world to send a clear message,” Ban said. “They want action on climate change.”
New studies increasingly highlight the ongoing effects of climate change, said Richard Moss, a member of the Nobel Peace Prize-winning Intergovernmental Panel on Climate Change and WWF’s climate change vice president.
“We have satellites and we have ships out at sea and we have monitoring stations set up on buoys in the ocean,” Moss said. “We monitor all kinds of things people wouldn’t even think about. The scientific research is showing in all kinds of ways that the climate crisis is worsening.”
This year’s Earth Hour has garnered support from global corporations, nonprofit groups, schools, scientists and celebrities — including Oscar-winning actress Cate Blanchett and Archbishop Desmond Tutu.
Nearly 200 US cities, towns and villages have signed on, from New York City — which will darken the iconic Empire State Building and Broadway marquees — to Igiugig, population 53 on Iliamna Lake in southwestern Alaska.
Among the efforts in Chicago, 50,000 light bulbs at tourist hotspot Navy Pier will dim and 24 spotlights that shine on the Sears Tower’s twin spires will go dark.
The Commonwealth Edison utility said electricity demand fell by 5 percent in Chicago and northern Illinois during last year’s Earth Hour, reducing carbon dioxide emissions by about 380 tonnes.
‘CROSSING THE LINE’: China’s embassy in Seoul criticized US Forces Korea Commander General Xavier Brunson, asking if his ‘hostile’ remarks were authorized by Washington South Korea and the US are in talks over recent public remarks by the commander of US Forces Korea, Seoul’s presidential office said yesterday, after the comments drew sharp criticism from China. In a recent podcast interview, US Forces Korea Commander General Xavier Brunson described South Korea as “the dagger in the heart of Asia” from China’s east coast, prompting the Chinese embassy in Seoul to say that he had “truly crossed the line.” The interview came amid growing speculation that Washington might seek to expand the role of US Forces Korea in countering the growing regional influence of China, a key
SEEKING ORDER: Rodrigo Paz said that ‘anyone who wants to destroy the nation will have to deal with this president and the full force of the constitution’ Bolivian President Rodrigo Paz on Wednesday said that the nation was at a “breaking point” after nearly a month of protests that have caused shortages of food, fuel and medicine. Paz, who took office six months ago amid the worst economic crisis there in four decades, is battling a groundswell of fury over his policies. The political capital, La Paz, has been besieged by low-income workers and members of the indigenous majority calling for his resignation. “The country needs order and is reaching breaking point,” the 58-year-old said at a public event in La Paz, renewing his appeal for dialogue. On Tuesday, the Bolivian
Forecasters in Europe yesterday warned of exceptional heat as record temperatures driven by a “heat dome” push temperatures well above seasonal norms across the continent. The surge follows a record-breaking Monday, with France logging its hottest day in the month of May on record, its weather agency said, and the UK also posting unprecedented highs. A so-called “heat dome” of warm air from northern Africa trapped under a high-pressure system over western Europe is behind the high temperatures not usually seen until high summer. Restrictions on outdoor work were imposed in parts of Italy, beaches in southwest France filled earlier than usual and
Australian researchers have trained lab-grown brain cells on a silicon computer chip to play the 1990s shooter game Doom and said they are just scratching the surface of what the neurons could be capable of doing. It is the science-fiction work of biotech boffins at Cortical Labs, who researched and developed the technology that harnesses the workings of the brain’s networking system. Each so-called “biological computer” contains about 200,000 living human brain cells, grown from stem cells that were harvested from blood donations.
