• The Rise of Indoor Cropping

    It's commonly accepted that record food prices were one of the key triggers for the Arab Spring. This year in Zimbabwe, critical levels of crop failure put over two million people at risk of chronic malnutrition. Even a prosperous state like Singapore, which imports over 90 percent of its produce, is starkly aware of its food security risks. Water scarcity, erratic weather conditions and a burgeoning global population, with rising expectations of living standards and an increasingly carnivorous diet, is driving pressure across the food chain. As food producers look for ways to boost productivity and safeguard their crops from an unpredictable climate, has the time come to take agriculture indoors? >> Read the Full Article
  • Record temperatures set to reach tropics first

    Tropical regions will be the first to experience unprecedented climate change, leading to significant upheaval for biodiversity and communities, according to a study published in Nature today. Regions near the equator will be subject to mean temperatures hotter than anything experienced on record an average of 15 years before the rest of the world, putting a strain on their rich biodiversity, which is adapted to stable climate conditions, finds the study. >> Read the Full Article
  • A Comprehensive Energy Productivity Portfolio

    Like a good financial portfolio, it appears that diversification is a successful strategy for America’s Energy Productivity according to the environmental action group, Natural Resources Defense Council. But, the NRDC notes that while the portfolio clearly should include a combination of all energies, the single most effective tool in maximizing our energy economy is to reduce consumption and extract the most out of every energy dollar spent. >> Read the Full Article
  • European Union on Track to Reach 2020 Climate Goals

    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. >> Read the Full Article
  • Climate modeling update

    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. >> Read the Full Article
  • Government Shutdown leaves Antarctic Research Operations in the cold

    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. >> Read the Full Article
  • Nitrogen Fixation

    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. >> Read the Full Article
  • Abengoa’s Gigantic "Salt Battery" Stores Utility-Scale Solar Energy

    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. >> Read the Full Article
  • Solar for Sure

    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. >> Read the Full Article
  • Plastics for Life

    This is no news flash, but plastics don't biodegrade. And yet almost 50% of it never sees a landfill. Worse, approximately 80% of the plastic debris in our oceans comes from the land. Plastics inevitably become part of our ecosystem from top to bottom. Of course, we think of the most pure environments as those in the highest mountaintops. The springs percolate into the headwaters on our mountain peaks, cascade down, hopping rocks and tumbling through forests into lakes, eventually emerging into larger rivers and ultimately out into the oceans. Along the way human influence affects their purity. Generally, we have hypothesized that water starts pure and becomes more polluted with each tier of drainage but recent research suggests that we are not starting with as clean a slate as we thought. >> Read the Full Article
