A senior United Nations chief has praised the measures taken by the UK to ensure that the London Summer Olympic Games are environmentally sustainable. Achim Steiner, executive director of the UN Environment Program (UNEP), says the eco achievements of the London 2012 Games should act as an inspiration for following organizers. "London’s clean-up of an old industrial site; the restoration of flows and habitat on the River Lea; the greening of supply chains; the low energy linked with the design and construction of the stadium, including utilizing old gas pipes for the facility’s Olympic ring; and the use of temporary structures to reduce emissions are among the actions that can assist in inspiring the organizers of the Rio 2016 games and beyond," he said.
End of the last Ice Age - Close linkage between CO2 and temperature found
July 24, 2012 06:58 AM - Staff, ClickGreen
The greatest climate change the world has seen in the last 100,000 years was the transition from the ice age to the warm interglacial period. New research from the Niels Bohr Institute at the University of Copenhagen indicates that, contrary to previous opinion, the rise in temperature and the rise in the atmospheric CO2 follow each other closely in terms of time. In the warmer climate the atmospheric content of CO2 is naturally higher. The gas CO2 (carbon dioxide) is a green-house gas that absorbs heat radiation from the Earth and thus keeps the Earth warm. In the shift between ice ages and interglacial periods the atmospheric content of CO2 helps to intensify the natural climate variations.
Uninformed Generation X are unconcerned about climate change

As the United States suffers a summer of record-shattering heat and the UK experiences record summer rainfall, a University of Michigan report finds that Generation X is lukewarm about climate change - uninformed about the causes and unconcerned about the potential dangers.
Pet owners show greater concern for the environment

Two-thirds of pet owners say they try to be good to the environment for the sake of their pet as much as a family member, according to new research from the Purina Together We Can campaign. The survey suggests that pet owners want to ensure that their pets can enjoy the great outdoors and they also want to preserve the planet for future generations of their beloved cats and dogs. When asked specifically about recycling, 29% of pet owners said that they do it to protect the environment for their pet. Overall, Britain's pet owners are setting a great example with 88% of them recycling their household waste either 'always' or 'often'.
Sea Level Rise may continue for Centuries
June 26, 2012 04:35 AM - Staff, ClickGreen
Sea levels around the world can be expected to rise by several meters in coming centuries, if global warming carries on, according to new research. The study is the first to give a comprehensive projection for this long perspective, based on observed sea-level rise over the past millennium, as well as on scenarios for future greenhouse-gas emissions. "Sea-level rise is a hard to quantify, yet critical risk of climate change," says Michiel Schaeffer of Climate Analytics and Wageningen University, lead author of the study. "Due to the long time it takes for the world's ice and water masses to react to global warming, our emissions today determine sea levels for centuries to come."
US bucks global trend of closing down nuclear power stations
June 8, 2012 10:31 AM - ClickGreen staff, ClickGreen
Official figures show Europe expects to decommission almost 150 of its nuclear power plants by 2030, while the US has granted life extensions to 71 and chosen to close only five, according to a report by energy experts GlobalData. The new report shows that the figure for Europe accounts for nearly 69% of the total global number of expected nuclear power reactor closures by 2030, the largest amount for any region. Barring any changes, the European commercial nuclear decommissioning market value stands at $81,484m.
World's biggest cities are tapping into the green economy benefits

Cities around the world have identified the economic benefits from tackling the effects of climate change, according to a new report released today by the Carbon Disclosure Project (CDP). The CDP study found 82% of cities are tapping into the potential for growth as a result of climate change adaptation and more than half of cities are looking to create green jobs and new business initiatives.
Kitchen air pollution is three-times higher than busy city centres

The air inside homes can have pollutant levels three-times higher than in city centres and along busy roads, according to a new study by the University of Sheffield.
Using cool materials to construct roads and walkways is an effective way of lowering urban temperatures to make cities more comfortable in hot weather, according to a new study. The research found surface temperatures were reduced by 12°C and ambient temperatures were reduced by 1.9°C after cool pavements were installed in a city park in Greece. Cities are known to exhibit the urban heat island effect, in which urban temperatures are higher than those of the surrounding rural areas. The phenomenon is created through a combination of heat released from human activities, such as air conditioning and traffic, in addition to decreased air flow and increased heat absorption by buildings, roads and other structures. In the future, climate change is likely to exacerbate the heat island effect with more frequent and extreme heat waves
Greenland glacier melt was faster in 1930s than today
May 30, 2012 06:44 AM - Staff, ClickGreen
A chance discovery of 80-year-old photo plates in a Danish basement is providing vital new clues into how Greenland glaciers are melting today. Researchers at the National Survey and Cadastre of Denmark - that country's federal agency responsible for surveys and mapping - had been storing the glass plates since explorer Knud Rasmussen's expedition to the southeast coast of Greenland in the early 1930s. In this week's online edition of Nature Geoscience, Ohio State University researchers and colleagues in Denmark describe how they analyzed ice loss in the region by comparing the images on the plates to aerial photographs and satellite images taken from World War II to today.
