California NEEDS dry farming!
July 18, 2014 09:40 AM - s.e. smith, Care2
Residents of California have been noting something disconcerting when they hit the grocery store this year: it's a terrible year for stone fruit. Despite the fact that it's the height of summer, peaches, nectarines, apricots, plums, cherries and their ilk are much more expensive than unusual, and of much poorer quality, too. What's going on? The answer lies in the state's extreme drought, which wreaked havoc on numerous crops this year, including stone fruit. The state's agriculture may be undergoing some major shifts in the coming years thanks to climate change and natural shifts in rainfall levels, and it's not the only region looking at a drier future.
Where are America's Greenest Buildings?
July 16, 2014 04:59 PM - Elisa Wood, Clean Techies
Ok, no surprise to see Washington, D.C. or San Francisco ranked high in a list of the cities with America's greenest buildings. But Atlanta? Georgia's capital was the only southern state to make the top ten in the 2014 U.S. Clean Tech Leadership Index, released July 15 by Clean Edge. The cleantech research firm tracks the cleantech progress of the 50 largest metro areas and the 50 states.
California getting tough with water wasters!
July 16, 2014 08:31 AM - L. CAROL RITCHIE, NPR
Californians who waste water will have to pay up to $500 a day for their extravagance under new restrictions approved Tuesday by the State Water Resources Control Board. The move comes after the board concluded that voluntary conservation measures have failed to achieve the 20 percent reduction in water use that Gov. Jerry Brown was hoping for, reports The Associated Press. In fact, a survey by the board showed a 1 percent increase in water use in May compared to the same month a year ago.
Fertilizer Threatens Grasslands Globally
July 15, 2014 05:10 PM - Paul Sutherland, MONGABAY.COM
The world's grasslands are being destabilized by fertilization, according to a paper recently published in the journal Nature. In a study of 41 grassland communities on five continents, researchers found that the presence of fertilizer weakened grassland species diversity. The researchers surveyed grasslands in countries around the world, such as China, the U.S., Switzerland, Tanzania and Germany, and discovered that grassland communities that had not been managed by humans contained more species. They also had greater species asynchrony, which means that different species thrive at different times so that the grassland produces more consistently over time, resulting in more stable biomass production.
Sand Power: A Better Battery
July 15, 2014 11:32 AM - Winfield Winter, ENN
Technology of the future is hard to see coming — sometimes because you can't see it. Advances in nanotechnology are the driving force behind longer lasting Lithium-ion batteries. Currently, Lithium-ion batteries are used to power every-day technologies like cell phones, computers, cameras and cars. Their energy source is a carbon-based graphite anode, which is nothing short of polarizing. Battery life has always been a major concern with Li-ion batteries. The solution is the most abundant compound in the earth's crust: SiO2, - or — more commonly — sand. The next generation of battery technology is using sand as a source for the production of nano-silicon, an anode material for Li-ion batteries.
Scalloped Hammerhead Sharks officially endangered, and that is not good news!
July 14, 2014 04:49 PM - s.e. smith, Care2, Care2
It’s not really the kind of "first" you want to be: The peculiar-looking but oddly beautiful scalloped hammerhead shark has just become the first shark species to be added to the US Endangered Species List. Sphyrna lewini, as they're known, are coastal to semi-oceanic sharks with a number of extremely vulnerable subpopulations. The move to classify them as endangered is in response to lobbying from several animal welfare groups who hoped to secure additional protections for these amazing creatures before it's too late.
Light rail systems DO improve air pollution in cities
July 13, 2014 08:59 AM - Roger Greenway, ENN
Have you ever wondered if the cute light rail systems some large cities are installing actually get people out of their cars and have a positive environmental impact? For the first time, researchers have shown that installing light rail on an existing traffic corridor not only gets people out of their cars, but reduces congestion and air pollution. In the study, planners at the University of Utah measured impacts of a new light rail line in Salt Lake City (University Line) on an existing major thoroughfare (400/500 South). Their analysis showed that traffic near the University has fallen to levels not seen since the 1980s, even as the number of students, faculty and staff at the U has increased, and the commercial district along the corridor has expanded.
Arctic sea ice trends confirmed by Whalers' logs
July 11, 2014 10:14 AM - Tim Radford, The Ecologist
Log books from British whaling ships more than 200 years ago have given new insights into the history of the Arctic sea ice, reports Tim Radford. A new study reveals that the scale of ice melt in the Arctic over the last few decades is new and unprecedented. The retreat of the ice in the last 30 years is part of a more recent and new pattern of climate change. British whaling ships from Tyneside in the north-east of England made 458 trips to the edge of the Arctic ice between 1750 and 1850.
Cell Phone Conservation
July 9, 2014 10:35 AM - Alex Kirby, The Ecologist
Some of the world's most endangered forests may soon benefit from better protection, thanks to discarded treasures from the consumer society - mobile phones. A Californian technology startup, Rainforest Connection (RFCx), has developed a tool - made from recycled smartphones - that it says will pilot new ways to monitor and stop illegal logging and animal poaching throughout Africa's equatorial forests. RFCx has formed a partnership with the Zoological Society of London (ZSL), an international scientific charity that works for the worldwide conservation of animals and their habitats. The two organisations are planning to install the anti-deforestation, anti-poaching technology in Cameroon this year.
Oceanic litter is widespread
July 8, 2014 08:18 AM - Harriet Jarlett, Planet Earth Online
Litter is now found in even the most remote areas of the oceans, say scientists trying to understand how much rubbish is lying at the bottom of Europe's seas. The new study, published in Plos One, shows for the first time that there seems to be no area of the ocean left untouched by human litter. Using 588 video clips collected by unmanned submarine vehicles for geological mapping and marine biology studies, the team found that plastics waste like shopping bags is the most prevalent.
