24 fewer days of winter ice
February 4, 2014 09:09 AM - ClickGreen Staff, ClickGreen
The winter ice season is now 24 days shorter than it was in 1950 as Arctic lakes are freezing up later in the year and thawing earlier, according to a new study. The University of Waterloo research, sponsored by the European Space Agency (ESA), also reveals that climate change has dramatically affected the thickness of lake ice at the coldest point in the season. In 2011, Arctic lake ice was up to 38 centimeters thinner than it was in 1950.

In a world which faces increasing pressure to reduce carbon emissions, the construction industry must confront demand to adopt modern methods of building which causes less damage to the environment. As a result, there are increasing numbers of alternative materials and methods available, a selection of which are included in this post. While these methods are by no means the only ones available within the industry, the selected materials and methods include: -Metallic paint -Chemical containment -Spray-on insulation -Concrete alternatives -Green roofs Each method boasts the more efficient properties in terms of reducing environmental damage, with the least change to standard methods.
The Effects of Third-hand Smoke
January 31, 2014 02:42 PM - ENN Staff
Many of us are familiar with first-hand smoke and second-hand smoke, but what about third-hand smoke? Well, you better get familiar with it because according to a new study conducted by researchers at the University of California, Riverside, the effects of third-hand smoke may be just as deadly as first-hand smoke. Let's break it down: First-hand smoke refers to the smoke inhaled by a smoker. Second-hand smoke refers to exhaled smoke and other substances emanating from a burning cigarette that can get inhaled by others. Third-hand smoke is the second-hand smoke that gets left on the surfaces of objects. Over time, these left over chemicals can age and becomes progressively more toxic.
Solar Energy is cash and sunshine in your pocket

Is there money to be made on your roof? With the never-ending availability of sunshine and the evolution of solar technology many are recognizing the benefits of solar. The decision making process though is not for the faint of heart. Recognizing the difficulty in breaking through the process a company called Generaytor out of Tel Aviv has developed a free web-based app to show how much money can be saved and made with rooftop solar panels.
Slowing down the floodwaters
January 29, 2014 10:41 AM - Robin Blackstone, ENN
Putting something called "Natural Engineering" to work in a five-year research project, Newcastle University in cooperation with the Environment Agency are discovering the benefits utilizing the land's natural defenses to slow river flow downstream and prevent flooding. Slowing down water in anticipation of flooding events is being tested all over the world. Strategies include the use of retention basins; wetlands development; levee systems and floodwalls but Newcastle University researchers directed by Dr. Mark Wilkinson are employing additional water retention strategies further up in the catchment system. The Belford Burn is a small catchment system located in Northumberland, a community just south of the Scottish border.
Linking Alzheimer's to environmental contributors
January 28, 2014 09:16 AM - Robin Lally, Rutgers University
Scientists have known for more than 40 years that the synthetic pesticide DDT is harmful to bird habitats and a threat to the environment. Now researchers at Rutgers University say exposure to DDT, banned in the United States since 1972 but still used as a pesticide in other countries, may also increase the risk and severity of Alzheimer's disease in some people, particularly those over the age of 60.
"Phosphate free for all" from P & G
January 27, 2014 09:26 AM - Click Green Staff, ClickGreen
Consumer product giant Procter & Gamble has announced that it will eliminate phosphates from all of its laundry detergents worldwide within the next two years. The change applies to brands including Tide, Ariel, Ace and Bonux, and will maximize the conservation of precious resources and reduce the threat of water pollution.
Emissions outsourced to China return to US as air pollution
January 24, 2014 09:00 AM - Editor, MONGABAY.COM
Twenty percent of China's air pollution can be attributed to goods exported to America, with some of those emissions drifting back to the Western United States, finds a study published this week in the journal Proceedings of the National Academy of Sciences. The research, conducted by an international team of researchers, estimates that Los Angeles sees at least one extra day of severe air pollution due to nitrogen oxides and carbon monoxide emitted by Chinese factories making products for export. On some days as much as a quarter of sulfate pollution on the California coastline can be attributed to Chinese export production.
Should governments give serious consideration to electric car only city centres? Over the last 12 months the subject of electric car only city centres has been discussed on numerous occasions although so far no government has been brave enough to push through any formal regulations. The authorities continue to encourage the use of electric vehicles within city centres, assisting with creating a network of recharging stations, but perhaps they could be doing more? Only a few days ago we wrote about an expert in the field of electric vehicles who is suggesting that financial incentives should be focused towards commercial operations such as taxis and vehicle fleets. The idea is that taxis and vehicle fleets cover the most mileage per annum compared to your traditional motorist and therefore electric vehicles will be more visible under this particular strategy.
Human response to climate
January 22, 2014 10:22 AM - B. Rose Huber, Woodrow Wilson School of Public and International Affairs, Princeton University
Throughout history, humans have responded to climate. Take, for example, the Mayans, who, throughout the eighth and 10th centuries, were forced to move away from their major ceremonial centers after a series of multi-year droughts, bringing about agricultural expansion in Mesoamerica, and a clearing of forests. Much later, in the late 20th century, frequent droughts caused the people of Burkina Faso in West Africa to migrate from the dry north to the wetter south where they have transformed forests to croplands and cut the nation's area of natural vegetation in half.
