European Union on Track to Reach 2020 Climate Goals
October 10, 2013 08:52 AM - Edouard Stenger, Clean Techies

According to the European Environment Agency, the European Union is already close to its 2020 climate objectives as it has decreased its emissions by no less than 18 percent between 1990 and 2012. Additionally, renewable energy sources such as wind, solar and many others were already accounting for 13 percent of the energy mix in 2011. The European Union have a comprehensive energy and climate plan as it has three objectives: 1. to slash its greenhouses gases emissions by 20 percent from 1990 to 2020 ; 2. to increase its energy efficiency by 20 percent ; 3. to increase its share of renewable energy sources to 20 percent of the mix by 2020.

Climate modeling update
October 10, 2013 06:30 AM - Roger Greenway, ENN

Climate models keep getting better but still can't predict with great certainty. So scientists run multiple models and look at the results of each model and calculate a consensus projection. The intent is to reduce the level of uncertainty by using a range of models with different types of shortcomings to hopefully improve confidence in the results. The seesaw variability of global temperatures often engenders debate over how seriously we should take climate change. But within 35 years, even the lowest monthly dips in temperatures will be hotter than we've experienced in the past 150 years, according to a new and massive analysis of all climate models. The tropics will be the first to exceed the limits of historical extremes and experience an unabated heat wave that threatens biodiversity and heavily populated countries with the fewest resources to adapt. Ecological and societal disruptions by modern climate change are critically determined by the time frame over which climates shift. Camilo Mora and colleagues in the College of Social Sciences' Department of Geography at the University of Hawaii at Mānoa have developed one such time frame. The study, titled "The projected timing of climate departure from recent variability," will be published in the October 10, 2013 issue of Nature and provides an index of the year when the mean climate of any given location on Earth will shift continuously outside the most extreme records experienced in the past 150 years.

Government Shutdown leaves Antarctic Research Operations in the cold
October 9, 2013 04:26 PM - Robin Blackstone, ENN

The National Science Foundation (NSF) has announced the suspension of all operations "not essential to the human safety and preservation of the property". This means that field and research activities will be wrapped up as the U.S. Antarctic Program (USAP) shifts into caretaker status. Funds for the program will dry up on or about October 14, 2013 as a result of the absence of appropriation and the Antideficiency Act just as the 2013-2014 summer austral program would have begun. Because much of the USAP work is dependent upon seasonal windows of opportunity, it will not be possible to restart many science activities for the remainder of the season. Researchers typically study birds, climate, weather and more in the remote and harsh climate.

Green Aerosol Cans? GreenSpence Says It Doesn’t Have To Be A Contradiction
October 9, 2013 01:11 PM - ISRAEL21c, NoCamels

They squirt, spray and lather. Some even give lifesaving bursts of medicine. But truth be told, the aerosol spray container hasn’t changed much in the last 60 years, says Gadi Har-Shai, CEO of the Israeli startup GreenSpense. Traditional aerosols are polluting and dangerous. So he invented a new alternative, the eco-sleeve, using nanotechnology.

Nitrogen Fixation
October 9, 2013 12:51 PM - Mrinalini Erkenswick Watsa , MONGABAY.COM

Nitrogen is colorless, odorless and tasteless, but all life on earth depends on it. Without it, our bodies cannot synthesize the nucleic acids that make up our DNA, or the protein-forming amino acids that are the very building blocks of our cells. Problematically, atmospheric nitrogen is relatively inert or nonreactive. This has created a unique biological dependency on a process called nitrogen fixation—where inert nitrogen from the atmosphere is converted into more reactive ammonia, a major component of soil fertilizers. A recent discovery has revealed just how reliant recovering forests are on nitrogen fixation, and how some forests can even manipulate it to speed up their abilities to 'heal' themselves. Many tropical forests today have been exploited for agriculture, mining, fossil fuel exploitation, and other human use.

Abengoa’s Gigantic "Salt Battery" Stores Utility-Scale Solar Energy
October 9, 2013 08:00 AM - Tina Casey, Triple Pundit

The global solar company Abengoa Solar has just announced that its massive Solana solar power plant has begun commercial operation in Arizona. The plant represents a transformational breakthrough in utility scale solar power, because it includes an energy storage system based on molten salt.

Solar for Sure
October 8, 2013 03:52 PM - The Vote Solar Initiative, Clean Techies

Yesterday, Governor Brown signed into law AB 327, a comprehensive rate reform bill to create more certainty for Californians who want to go solar, ensuring rooftop solar is here to stay in California! The Governor issued a signing statement for AB 327 directing the CPUC to ensure that customers who go solar under the current 5% program cap will get to stay under current program rules for the life of their solar array. That's important direction for the agency as it implements the bill in 2014.

It’s not easy being green — unless that is, you live on a boat. Part IV.
October 8, 2013 07:45 AM - Clare Kendall, The Ecologist

In her fourth and final blog Clare Kendall recommends trying a boat holiday - which tend to have serious green credentials........ If you've been inspired by the thought of canal boat living (see my previous blogs) why not try a narrow boat holiday. It's one of the greenest holiday options you can take.

Good news for European wildlife
October 8, 2013 06:16 AM - Luke Dale-Harris, The Ecologist

From Eastern Europe, Luke Dale-Harris argues that the extent to which the findings of a recently published report can be considered positive depend on one's perspective of rewilding......... A couple of weeks ago the unusual happened. Europe received positive news about the environment. Not just a claim that maybe things aren’t quite as bad as we previously thought, but the release of a report which shows, quite clearly, that for many species across large swathes of Europe, things haven't been better for decades.

New Fish Trap Reduces Bycatch and Increases Profits
October 7, 2013 03:46 PM - Wildlife Conservation Society

Scientists from the Wildlife Conservation Society and the Kenyan Marine and Fisheries Research Institute have achieved a milestone in Africa: they've helped build a better fish trap, one that keeps valuable fish in while letting undersized juvenile fish and non-target species out. By modifying conventional African basket traps with escape gaps, the marine researchers have proven that the new traps catch larger fish, allow more undersized and non-target fish to escape, increase profits, and—most importantly—minimize the impact of fishing on coastal reef systems. The findings, say researchers, will help fishing communities boost profits while protecting their vital marine resources.
