• Triassic End Times

    The End Triassic extinction event was an extinction event that occurred over 200 million years ago. At least half of the species known to have been living on Earth at that time went extinct. This event vacated terrestrial ecological niches, allowing the dinosaurs to assume the dominant roles in the Jurassic period. This event happened in less than 10,000 years and occurred just before Panagea started to break apart. Scientists examining evidence across the world from New Jersey to North Africa say they have linked the abrupt disappearance of half of earth’s species 200 million years ago to a precisely dated set of gigantic volcanic eruptions. The eruptions may have caused climate changes so sudden that many creatures were unable to adapt—possibly on a pace similar to that of human-influenced climate warming today. The extinction opened the way for dinosaurs to evolve and dominate the planet for the next 135 million years, before they, too, were wiped out in a later planetary cataclysm. This study provides the tightest link yet, with a newly precise date - 201,564,000 years ago, exactly the same time as a massive outpouring of lava. >> Read the Full Article
  • Sinkhole Threatens Louisiana Community

    Sinkholes have been making headlines in the news lately like when earlier this month, a Florida man was unfortunately pulled to his death because of the mysterious land collapse. Florida in particular is prone to sinkholes because of underground limestone caverns in which the rock is extremely porous and dissolves easily in water. This softening causes land to sink and the event has the ability to collapse without warning, swallowing whatever lies above ground causing fatal destruction. While sinkholes are naturally occurring depressions in the Earth’s surface that vary in both diameter and depth, they can also be caused by man-made industries, and consequently, a massive sinkhole in Louisiana is threatening an entire community. >> Read the Full Article
  • Achieving a Sustainable Food System with Organic Farming

    Despite a slight decline between 2009 and 2010, since 1999 the global land area farmed organically has expanded more than threefold to 37 million hectares, according to new research conducted by the Worldwatch Institute for its Vital Signs Online service (www.worldwatch.org). Regions with the largest certified organic agricultural land in 2010 were Oceania, including Australia, New Zealand, and Pacific Island nations (12.1 million hectares); Europe (10 million hectares); and Latin America (8.4 million hectares), write report authors Catherine Ward and Laura Reynolds. >> Read the Full Article
  • Iron and Life and Volcanic Ash

    In 2010, there was a large volcanic eruption spewing tons of ash into the atmosphere and into the sea. The ash caused major flight delays as well as posing potential health hazards. Nevertheless, the Icelandic volcano's ash plume resulted in the oceans absorbing more carbon dioxide (CO2) than usual, say scientists. In about a third of the global ocean, the abundance of life is limited by a lack of biologically available iron. The supply of iron to a region that is depleted in this important nutrient can stimulate algal productivity, and can result in a temporary boom in biological activity. For much of the surface ocean, the wind-borne transport of iron-rich dust and the upwelling of nutrient-filled water are the normal major sources of iron. >> Read the Full Article
  • Happy World Water Day!

    All across the globe, communities are celebrating International World Water Day and according the UN's World Water Day website, over 450 events have been planned this year! This year's theme is in part a reflection of the International Year of Water Cooperation. The day is also dedicated to the theme of cooperation that is emphasized concerning using water as a resource. Not only is the environment heavily dependent on water, but as a basic human need, good management of water sources is crucial to our own livelihood. In correlation with this environmental holiday, we are encouraged to promote water cooperation and do our part in protecting one of Earth's most valuable resources as this year marks the 10th anniversary of the celebration that was recommended during the 1992 UN Conference on Environment and Development. So in celebration of today, we are urging our readers to limit your water use! >> Read the Full Article
  • 8 Frogs Discovered in 1 Sanctuary

    Two surveys in the mountainous forests of Sri Lank's Peak Wilderness Sanctuary have uncovered eight new species of frogs, according to a massive new paper in the Journal of Threatened Taxa. While every year over a hundred new amphibians are discovered, eight new discoveries in a single park is especially notable. Sri Lanka is an amphibian-lovers paradise with well over 100 described species, most of which are endemic, i.e. found only on the small island country. Unfortunately the country has also seen more frog extinctions than anywhere else, and seven of the eight new species are already thought to be Critically Endangered. >> Read the Full Article
  • Redfield's Ratio Refuted

    The Redfield ratio has been a fundamental feature in understanding the biogeochemical cycles of the oceans and has been used since 1934 when oceanographer Alfred Redfield found that the elemental composition of marine organic matter is constant across all regions. By analyzing samples of marine biomass, Redfield found that the stoichiometric ratios of carbon, nitrogen, phosphorus remain consistent with a ratio of 106:16:1 in ocean regions. However, according to new work by UC Irvine and other researchers, models of carbon dioxide in the world's oceans need to be revised. >> Read the Full Article
  • German Research Institute Drops Canadian Tar Sands Project

    The Helmholtz-Association of German Research Centres has just backed out of a CAN$25 million research project funded by the Canadian government that would study sustainable solutions for tar sands pollution. Canada is home to the world's third largest crude reserves in the form of tar sands. Tar sands are a type of unconventional petroleum deposit and are considered part of the world's oil reserves as new technology can extract oil from these sands. >> Read the Full Article
  • The Looming Threat of Water Scarcity

    Some 1.2 billion people—almost a fifth of the world—live in areas of physical water scarcity, while another 1.6 billion face what can be called economic water shortage. The situation is only expected to worsen as population growth, climate change, investment and management shortfalls, and inefficient use of existing resources restrict the amount of water available to people, according to Worldwatch Institute’s Vital Signs Online service (www.worldwatch.org). It is estimated that by 2025, 1.8 billion people will live in countries or regions with absolute water scarcity, with almost half of the world living in conditions of water stress. Water scarcity has several definitions. Physical scarcity occurs when there is not enough water to meet demand; its symptoms include severe environmental degradation, declining groundwater, and unequal water distribution. Economic water scarcity occurs when there is a lack of investment and proper management to meet the demand of people who do not have the financial means to use existing water sources; the symptoms in this case normally include poor infrastructure.Large parts of Africa suffer from economic water scarcity. >> Read the Full Article
  • The Red-Dead water conveyer can avoid a dead end

    The Red-Dead canal could take a small step forward in light of projected environmental impacts and other constraints, says Batir Wardam. After a delay of more than six months, the World Bank has finally released the final drafts of the feasibility and environmental assessment studies for the controversial Red Sea-Dead Sea Water Conveyance project, designed to channel some 1.2 billion cubic metres of water 180 kilometres from the Red Sea to the Dead Sea. >> Read the Full Article
