Almost all climate scientists agree that actions must be taken to lower carbon emissions, also known as greenhouse gases, to reduce the risk of damage to the environment and ultimately human health. A group of researchers say adding carbon labels to products could help change purchasing behavior and corporate supply chains, ultimately leading to large emissions reductions. They propose a private labeling system to fill the gap until national and international rules are adopted.
With more and more environmentally conscious consumers choosing “green” products, scientists today reported that the first reality check has revealed that the ingredients in those product may come from a surprising source –– petroleum, rather than natural plant-based sources.
Scientists are reporting development of a quick, efficient method for recycling automotive waste oil into fuel. The new method could help dispose of the estimated 24 million tons of waste oil produced each year worldwide and provide a supplemental fuel source for an energy-hungry world. Scientists will describe the new method, the first to use microwaves to convert waste oil to fuel, at the 241st National Meeting of the American Chemical Society in Anaheim.

Russia's boreal forest – the largest continuous expanse of forest in the world, found in the country's cold northern regions – is undergoing an accelerating large-scale shift in vegetation types as a result of globally and regionally warming climate. That in turn is creating an even warmer climate in the region, according to a new study published in the journal Global Change Biology.
Your next car hopefully won’t be a lemon. But it could be a pineapple, banana, or some other tropical fruit. That’s because scientists in Brazil are reporting an advance toward the long-awaited “bio-automobile” …. developed a convenient way to turn fruit fibers into nanoparticles to improve the performance and eco-friendliness of automobile plastics, including bumpers and dashboards. Scientists will describe the new method and materials at the 241st National Meeting and Exposition of the American Chemical Society in Anaheim, Calif.
In a finding that could help meet the growing energy demands of billions of people worldwide in a simpler, more efficient and less-costly way, a noted scientist is reporting long-awaited development of the first practical “artificial leaf.” The solar-powered device mimics the chemical process, called photosynthesis, that plants use to convert sunlight into fuel, said chemist Daniel Nocera. He will describe the device at the 241st National Meeting of the American Chemical Society in Anaheim.
Study by Wildlife Conservation Society, AMNH, on dolphins finds invisible oceanographic factors that keep populations separate.
Prescribed fires are often used to control undesirable species and enhance herbaceous biomass production. But what are the results when a wildfire burns out of control? In March 2006, more than 367,000 hectares burned in wildfires known as the East Amarillo Complex that raged in the U.S. Texas Panhandle. By studying the survival and regrowth of plants from these wildfires, scientists can learn more about its effects on the ecosystem.

Young children who mouth or swallow jewelry containing cadmium may be exposed to as much as 100 times the recommended maximum exposure limit for the toxic metal, according to research published online March 4 ahead of print in the peer-reviewed journal Environmental Health Perspectives (EHP). The study measured bioavailability, or how much cadmium leached out of the jewelry. The research also found that damaged pieces of jewelry in some cases leached up to 30 times more cadmium than undamaged pieces.
