NASA's latest satellite data reveals global sea level rise Global sea levels have risen nearly 3 inches in less than 25 years, with some locations around the world rising more than 9 inches, according to NASA’s latest satellite data. An intensive research effort now underway, aided by NASA observations and analysis, points to an unavoidable rise of several feet in the future.
Carbon Credits Under Kyoto Protocol Actually Increased Emissions At the end of November, governments will come together in Paris to hammer out agreements for a successor to the Kyoto Protocol. Under the KP, there are two greenhouse gas (GHG) emissions offsetting mechanisms: joint implementation (JI) and the Clean Development Mechanism (CDM).JI allows countries with emissions-reduction commitments under the Kyoto Protocol to generate Emission Reduction Units (ERUs) from GHG reduction projects and transfer them to other countries. Almost 872 million ERUs had been issued under JI as of March 2015, about a third of all Kyoto offset credits. In a nutshell, JIs are carbon credits and include things like reforestation projects.
The Fingerprints of Sea Level Rise When you fill a sink, the water rises at the same rate to the same height in every corner. That's not the way it works with our rising seas.According to the 23-year record of satellite data from NASA and its partners, the sea level is rising a few millimeters a year -- a fraction of an inch. If you live on the U.S. East Coast, though, your sea level is rising two or three times faster than average. If you live in Scandinavia, it's falling. Residents of China's Yellow River delta are swamped by sea level rise of more than nine inches (25 centimeters) a year.These regional differences in sea level change will become even more apparent in the future, as ice sheets melt. For instance, when the Amundsen Sea sector of the West Antarctic Ice Sheet is totally gone, the average global sea level will rise four feet. But the East Coast of the United States will see an additional 14 to 15 inches above that average.
Trash or Treasure? Repurposing Food Waste to Feed the Hungry and Create Jobs "If I offered you a bruised banana, you probably wouldn’t be interested,” said Jonathan Deutsch, PhD, director of Drexel University’s Center for Hospitality and Sport Management. “But what if I offered you some banana ice cream on a hot summer day? I bet you’d find that a lot more appealing.”It was this simple observation that inspired a new model for recovering would-be wasted – or surplus – food and repurposing it to feed hungry people, generate revenue and even create jobs. The model was recently piloted in West Philadelphia, home to a large population of low-income and food insecure individuals, as part of the Environmental Protection Agency’s Food Recovery Challenge with support from Brown’s Super Stores.Compiled by researchers from Drexel University, University of Pennsylvania, Cabrini College and the EPA, the results were published in Food and Nutrition Sciences, a peer-reviewed international journal dedicated to the latest advancements in food and nutrition sciences. The report also projects the amount of food that could be saved if the program was replicated nationally.
Plastic particles found in cosmetics Everyday cosmetic and cleaning products contain huge quantities of plastic particles, which are released to the environment and could be harmful to marine life, according to a new study. Research at Plymouth University has shown almost 100,000 tiny ‘microbeads’ – each a fraction of a millimetre in diameter – could be released in every single application of certain products, such as facial scrubs.
Anti-aging proteins Individuals previously diagnosed with heart disease may be less likely to experience heart failure, heart attacks, or stroke, or to die from these events, if they have higher blood levels of two very closely related proteins, according to a new study led by a UC San Francisco research team.One of these proteins, known as GDF11, has attracted great interest since 2013, when researchers showed that it could rejuvenate old mice. Based on these findings, scientists have speculated that drugs that increase GDF11 levels might reverse physiological manifestations of aging that lead to heart failure in people.
Access to nature may help you sleep better Men and persons age 65 and older who have access to natural surroundings, whether it’s the green space of a nearby park or a sandy beach and an ocean view, report sleeping better, according to a new University of Illinois study published in Preventive Medicine.
