Climate cycles are driving wars, says study - 0 views

  •  
    In the first study of its kind, researchers have linked a natural global climate cycle to periodic increases in warfare. The arrival of El Niño, which every three to seven years boosts temperatures and cuts rainfall, doubles the risk of civil wars across 90 affected tropical countries, and may help account for a fifth of worldwide conflicts during the past half-century, say the authors. The paper, written by an interdisciplinary team at Columbia University's Earth Institute, appears in the current issue of the leading scientific journal Nature.

Help Track the Death of the Night Sky - 0 views

  •  
    Using a web app that is provided online, participants are asked to attempt to identify certain constellations and, if they can, rate them against magnitude charts. The project tracks the increasing problem of disappearing darkness, which can interrupt the cycles of plant and animal life, eventually to a fatal degree.

Global warming may affect the capacity of trees to store carbon, study finds - 0 views

  •  
    global warming may affect the capacity of trees to store carbon by altering forest nitrogen cycling, concludes a study led by Jerry Melillo, Distinguished Scientist at the Marine Biological Laboratory (MBL) Ecosystems Center, and published this week in Proceedings of the National Academy of Sciences.

The future of cover crops - 0 views

  •  
    Winter cover crops are an important component of nutrient cycling, soil cover and organic matter content. Although its benefits are well documented, cover crop use in farming systems is relatively low. Research has shown that time and money are the two primary reasons why farmers are hesitant to adopt the technique. Developing innovative and cost-effective crop cover systems could increase the use of winter cover crops.

Humans and climate contributed to extinctions of large ice-age mammals, study finds - 0 views

  •  
    Both climate change and humans were responsible for the extinction of some large mammals, like the musk ox in this photo, according to research that is the first of its kind to use genetic, archeological, and climatic data together to infer the population history of large Ice-Age mammals. The large international team's research, which will be published in the journal Nature, is expected to shed light on the possible fates of living species of mammals as our planet continues its current warming cycle.

Antarctic icebergs play a previously unknown role in global carbon cycle, climate - 0 views

  •  
    In a finding that has global implications for climate research, scientists have discovered that when icebergs cool and dilute the seas through which they pass for days, they also raise chlorophyll levels in the water that may in turn increase carbon dioxide absorption in the Southern Ocean.

Batteries for the future - 0 views

  •  
    One of the most important decisions facing designers of plug-in electric or hybrid vehicles is related to battery choice. Now, researchers at the Norwegian University of Science and Technology (NTNU) have used a life cycle analysis to examine three vehicle battery types to determine which does the best job of powering the vehicle while causing the least amount of environmental impact during its production.

Gray whales likely survived the Ice Ages by changing their diets - 0 views

  •  
    Gray whales survived many cycles of global cooling and warming over the past few million years, likely by exploiting a more varied diet than they do today, according to a new study by University of California, Berkeley, and Smithsonian Institution paleontologists.

Using duck eggs to track climate change - 0 views

  •  
    thanks to a research project that is the next best thing to time travel, DeJong is measuring the duck eggs in several museum collections - from the Smithsonian Institution, in this case, where Bendire was the first curator of the discipline known as oology, or the study of birds' eggs. When her project is done, DeJong will have assembled and analyzed a metrics database on perhaps 60,000 duck eggs representing at least 40 species and subspecies of ducks found in North America.
