A Second Use for Cigarette Butts

It is estimated that as many as 5.6 trillion used-cigarettes, or 766,571 metric tons, are deposited into the environment worldwide every year. That's a lot of litter, especially when it takes 18 months to 10 years for cigarette filters to degrade! However, these butts may have a newly discovered second use as a group of South Korean scientists have converted these cigarette leftovers into a high-performing material that could be integrated into computers, handheld devices, electrical vehicles and wind turbines. >> Read the Full Article

Survey Ranks U.S. as Biggest Climate Change Denier

This may confirm suspicions that many of us have already had. Besides leading the world in consumer debt and military spending, the U.S. can now add climate denial to that list. That is, according to a Global Trends survey by the U.K.-based market research firm Ipsos MORI. The study polled 16,000 people in 20 leading countries on eight different topics, including the environment. Not only was the U.S. last, but it was last by a considerable margin. >> Read the Full Article

Spray-on Solar Panels?

A team of scientists at the University of Sheffield are the first to fabricate perovskite solar cells using a spray-painting process – a discovery that could help cut the cost of solar electricity. Experts from the University's Department of Physics and Astronomy and Department of Chemical and Biological Engineering have previously used the spray-painting method to produce solar cells using organic semiconductors - but using perovskite is a major step forward. >> Read the Full Article

Co-evolution Benefits Aborigines and Kangaroos

Australia's Aboriginal Martu people hunt kangaroos and set small grass fires to catch lizards, as they have for at least 2,000 years. A University of Utah researcher found such man-made disruption boosts kangaroo populations – showing how co-evolution helped marsupials and made Aborigines into unintentional conservationists. "We have uncovered a framework that allows us to predict when human subsistence practices might be detrimental to the environment and when they might be beneficial," says Brian Codding, an assistant professor of anthropology. >> Read the Full Article

Atlantic Ocean warming linked to Pacific trade winds

New research has found rapid warming of the Atlantic Ocean, likely caused by global warming, has turbocharged Pacific Equatorial trade winds. Currently the winds are at a level never before seen on observed records, which extend back to the 1860s. The increase in these winds has caused eastern tropical Pacific cooling, amplified the Californian drought, accelerated sea level rise three times faster than the global average in the Western Pacific and has slowed the rise of global average surface temperatures since 2001. >> Read the Full Article

Toledo, Ohio water problems

The City of Toledo has issued a "Do Not Drink" advisory for residents served by Toledo Water after chemical tests confirmed the presence of unsafe levels of the algal toxin Microcystin in the drinking water plant’s finished water. The advisory, spanning three counties in Ohio and one in Michigan, leaves more than 400,000 people in the Toledo area without drinking water. "Do not drink the water," Melanie Amato, public information officer for the Ohio Department of Health, told Circle of Blue. "You can shower in it, bathe in it, but do not try to ingest it. That means no washing dishes; you can brush your teeth with it as long as you don’t swallow any water, but we recommend using bottled water for that as well." >> Read the Full Article

Study predicts climate change and pollution will combine to impact food production

Many studies have shown the potential for global climate change to cut food supplies. But these studies have, for the most part, ignored the interactions between increasing temperature and air pollution -- specifically ozone pollution, which is known to damage crops. A new study involving researchers at MIT shows that these interactions can be quite significant, suggesting that policymakers need to take both warming and air pollution into account in addressing food security. >> Read the Full Article

Surf's Up for Clean Technology

Unless your skin is about a foot thick, swimming and surfing in the Pacific Ocean for hours at a time requires a wetsuit to stay warm and comfortable. That comfort, however, comes at a price as the vast majority of wetsuits are made from petroleum-based neoprene. The material is durable and does the job, but its manufacture is a carbon-intensive and toxic process. Now Patagonia is aggressively promoting its plant-based wetsuit technology with the goal to have it become a game-changer in the surf industry. >> Read the Full Article

Underestimating the Impacts of Old-Growth Logging

Ecologists may be underestimating the impact of logging in old-growth tropical forests by failing to account for subtleties in how different animal groups respond to the intensity of timber extraction, argues a paper published today in the journal Current Biology. The study, led by Zuzana Burivalova of ETH Zurich, is based on a meta-analysis of 48 studies that evaluated the impact of selective logging on mammals, birds, amphibians, and invertebrates in tropical forests. Burivalova, together with co-authors Cagan Sekercioglu and Lian Pin Koh, found that biodiversity is inversely proportional to logging intensity. >> Read the Full Article

Defending against sea level rise could make the problem worse

A combination of coastal defences and rising sea levels could change typical UK tidal ranges, potentially leading to a higher risk of flooding, say scientists. The researchers wanted to find out how tides around the UK might respond to changes in sea level over the next century depending on the level of coastal defences in place. >> Read the Full Article
