  • Continued Emissions May Cause Global North-to-South Shift in Wind Power By End of Century

     In the next century, wind resources may decrease in many regions of the Northern Hemisphere and could sharply increase in some hotspot regions down south, according to a study by University of Colorado Boulder researchers. The first-of-its-kind study predicting how global wind power may shift with climate change appears today in Nature Geoscience.

  • Study opens window on meltwater from icebergs

    Surface water conditions in Greenland’s fjords and in the northern Atlantic Ocean are dictated by what’s going on deep below the surface next to the massive Greenland Ice Sheet, UO-led research has found.Breakaway icebergs, according to research findings appearing online Dec. 4 ahead of publication in the journal Nature Geoscience, are the biggest source of freshwater entering the ocean in key areas around Greenland. And the timing and location of meltwater are important factors that should be included in ocean modeling, report the paper’s six co-authors.

  • Algae Growth Reduces Reflectivity, Enhances Greenland Ice Sheet Melting

    New research shows algae growing on the Greenland ice sheet, the Earth’s second-largest ice sheet, significantly reduce the surface reflectivity of the ice sheet’s bare ice area and contribute more to its melting than dust or black carbon. The new findings could influence scientists’ understanding of ice sheet melting and projections of future sea level rise, according to the study’s authors.

  • Researchers Identify Nontraditional Sites for Future Solar Farms

    Equivalent of 183,000 football fields of nonagricultural land identified in study aiming to ease competition between farmers, conservationists, and energy companies.

  • Pesticides and Poor Nutrition Damage Animal Health

    The combined effects of pesticides and a lack of nutrition form a deadly one-two punch, new research from biologists at the University of California San Diego has shown for the first time.

  • China Announces Details of New Carbon Trading Market

    China has released plans to create the world’s largest carbon emissions trading scheme, several news outlets reported. The market will initially be focused on the power sector, which produced almost half of the country’s greenhouse gas emissions last year, and will encompass 1,700 energy suppliers producing more than 3 billion tons of CO2 annually, according to Reuters.

  • Texas A&M Team Making Models To Predict Droughts

    Drought-predicting computer models are not made just so that scientists can say “I told you so” when your favorite lake runs low. From agriculture, to infrastructure, to tourism — major sectors of the economy need a heads-up on what weather conditions are coming down the pipe.

  • Research finds North Atlantic Oscillation synchronises tree reproduction across Europe

    Research by the University of Liverpool has found a strong correlation between the North Atlantic Oscillation and synchronised tree reproduction across Europe, supporting the idea that this phenomenon plays a greater role in large scale masting, the process whereby forest trees produce large numbers of seeds in the same year.

  • Warming Seas Double Snowfall Around North America's Tallest Peaks

    Snowfall on a major summit in North America’s highest mountain range has more than doubled since the beginning of the Industrial Age, according to a study from Dartmouth College, the University of Maine, and the University of New Hampshire.

  • Healthier Air due to the Low Emission Zone

    The Low Emission Zone in Leipzig was established in March 2011, allowing only access of Diesel vehicles of Euro4 and higher with few exceptions. The ban of older vehicles and subsequent modernization of the car fleet resulted in slightly reduced PM10 and PM2.5 mass concentrations. However, the mass concentration of black carbon (soot particles) emitted mainly from Diesel vehicles decreased by 60% at the street site. These particles are believed to be most dangerous due to their carcinogenic trace compounds such as polycyclic aromatic hydrocarbons. Furthermore, also the number concentration of ultrafine particles, which can penetrate deep into the lungs, decreased by approximately 70%. Despite modernized Diesel vehicles, nitrogen oxides concentrations did not follow these trends and remained nearly constant. The main achievement of the Low Emission Zone was the improvement of air quality by the reduction of the most dangerous particles.
