The Scottish Islands could make a significant contribution to the UK's 2020 renewable energy targets, according to a joint report by the UK and Scottish Governments. The research considers the evidence base for developing renewables projects on the Scottish Islands. And the Scottish Islands Renewables Project report shows that while there are significant potential benefits to developing renewables on the Scottish Islands, there are also considerable costs that need to be overcome.
Keeping Produce Fresh Longer
May 15, 2013 01:49 PM - Allison Winter, ENN
Billions of dollars of fruits, vegetables, and flowers are thrown away each year as produce ripens too quickly and starts to rot in different markets before public buyers even buy them. Even though you might expect these products to start rotting to their death after they are first harvested, researchers explain that fruits, vegetables and flowers are still alive after they are picked. In fact, once these products are picked, they produce and release into the air ethylene gas, a crucial component for the ripening and blooming process.
Should We Change the Climate If We Could?
May 15, 2013 09:25 AM - Andy Soos, ENN
Geoengineering is the deliberate and large-scale intervention in the Earth’s climatic system with the aim of reducing global warming. Who should do it and when? Anything done has the possibility of affecting everybody so who should be consulted? Who decides such world spanning concepts? A new study investigated these concerns. The findings are the result of the first UK public engagement study to explore the ethics and acceptability of so-called solar radiation management (SRM) technology, and a proposed field trial for a possible deployment mechanism.
Industrialized fishing has forced seabirds to change what they eat
May 15, 2013 08:47 AM - Jeremy Hance, MONGABAY.COM
The bleached bones of seabirds are telling us a new story about the far-reaching impacts of industrial fisheries on today's oceans. Looking at the isotopes of 250 bones from Hawaiian petrels (Pterodroma sandwichensis), scientists have been able to reconstruct the birds' diets over the last 3,000 years. They found an unmistakable shift from big prey to small prey around 100 years ago, just when large, modern fisheries started scooping up fish at never before seen rates. The dietary shift shows that modern fisheries upended predator and prey relationships even in the ocean ocean and have possibly played a role in the decline of some seabirds.
What Do You Think About Geo-engineering?
May 15, 2013 07:16 AM - Harriet Jarlett, Planet Earth Online
Few members of the UK public are comfortable with the idea of injecting aerosols high into the atmosphere to help slow down climate change, a study has found. People voiced concerns that this type of approach fails to address the basic problem of increasing greenhouse gas emissions. They are also nervous about any unintended consequences of such an action. But most significantly, they say that injecting aerosols into the Earth's atmosphere raises problems of international governance and control: who would ultimately be responsible?
Rocky Mountain Snow Packs
May 14, 2013 04:14 PM - Andy Soos, ENN
Snow pack forms from layers of snow that accumulate in geographic regions and high altitudes where the climate includes cold weather for extended periods during the year. Snow packs are an important water resource that feed streams and rivers as they melt. Warmer spring temperatures since 1980 are causing an estimated 20 percent loss of snow cover across the Rocky Mountains of western North America, according to new research from the U.S. Geological Survey. The new study builds upon a previous USGS snow pack investigation which showed that, until the 1980s, the northern Rocky Mountains experienced large snow packs when the central and southern Rockies experienced meager ones, and vice versa. Yet, since the 1980s, there have been simultaneous snow pack declines along the entire length of the Rocky Mountains, and unusually severe declines in the north.
Eat Insects To Mitigate Deforestation and Climate Change
May 14, 2013 12:17 PM - Jeremy Hance, MONGABAY.COM
A new 200-page-reportby the UN Food and Agriculture Organization (FAO) urges human society to utilize an often-ignored, protein-rich, and ubiquitous food source: insects. While many in the industrialized west might turn up their noses at the idea of eating insects, already around 2 billion people worldwide eat over 1,900 species of insect, according to the FAO. Expanding insect-eating, the authors argue, may be one way to combat rising food needs, environmental degradation, and climate change.
Mussels May Help Filter Polluted Waters
May 14, 2013 10:28 AM - Editor, ENN via YaleEnvironment360
Scientists from the U.S. National Oceanic and Atmospheric Administration (NOAA) set up an experimental raft at the mouth of New York City's Bronx River last spring. Hanging beneath it were long, sock-like tendrils that had been seeded with Geukensia demissa, commonly known as ribbed mussels. The point of the two-year experiment was to see whether mussels would survive or even thrive given the industrial and organic effluent that flows from the Bronx into the greater New York Harbor. If the mussels did in fact prosper in this environment, it could have implications for how we might help clean up coastal waters in various parts of the world.
Glaciers in the Mount Everest region have shrunk by 13 percent and the snow-line has shifted 180 meters (590 feet) higher during the past 50 years, according to a study that will be presented this week at a conference organized by the American Geophysical Union.
Eating More Protein is Associated with Weight Loss
May 14, 2013 08:44 AM - Editor, Justmeans
At some point in our lives, we have been on some kind of diet or other. There is the 'cabbage soup diet'; '5:2 diet'; and then high protein diets such as Atkins, Zone and South Beach, etc. Some people turn to higher-protein diets to lose weight, because some studies suggest that higher-protein diets help people better control their appetites and calorie intake. Diets with 30 per cent protein are now considered "reasonable" and the term "high protein diet" is now reserved for diets with over 50 per cent protein.
