  • Rain or snow? Humidity, location can make all the difference, new map shows
    on March 20, 2018 at 12:43 pm

    Researchers have created a map of the Northern Hemisphere showing how location and humidity can affect precipitation, illustrating wide variability in how and why different areas receive snow or rain. […]

  • Coral reef experiment shows: Acidification from carbon dioxide slows growth
    on March 14, 2018 at 6:50 pm

    Ocean acidification will severely impair coral reef growth before the end of the century if carbon dioxide emissions continue unchecked. The paper represents the first ocean acidification experiment in which seawater was made artificially acidic by the addition of carbon dioxide and then allowed to flow across a natural coral reef community. The acidity of the seawater was increased to reflect end-of-century projections if carbon dioxide from greenhouse gas emissions are not abated. […]

  • Elephant declines imperil Africa's forests
    on March 12, 2018 at 7:05 pm

    Poaching and habitat loss have reduced forest elephant populations in Central Africa by 63 percent since 2001. This poses consequences not only for elephants but also for the region's forests, a new study finds. Without intervention to stop poaching, as much as 96 percent of Central Africa's forests will undergo major changes in tree-species composition and structure as local populations of elephants disappear and surviving populations are crowded into ever-smaller forest remnants. […]

  • Diverse tropical forests grow fast despite widespread phosphorus limitation
    on March 7, 2018 at 8:39 pm

    Ecological theory says that poor soils limit the productivity of tropical forests, but adding nutrients as fertilizer rarely increases tree growth, suggesting that productivity is not limited by nutrients after all. Researchers resolved this apparent contradiction, showing that phosphorus limits the growth of individual tree species but not entire forest communities. Their results have sweeping implications for understanding forest growth and change. […]

  • Rapid pollution increases may be as harmful to the heart as absolute levels
    on February 15, 2018 at 11:03 pm

    Rapid increases in pollution may be as harmful to the heart as sustained high levels, according to new research. The authors urgently call for confirmatory studies as even residents of clean air cities could be at risk. […]

  • Central Valley soil emissions a large source of California's nitrogen oxide pollution
    on January 31, 2018 at 9:03 pm

    A previously unrecognized source of nitrogen oxide is contributing up to about 40 percent of the NOx emissions in California, according to a new study. The study traces the emissions to fertilized soils in the Central Valley region. […]

  • Tiny particles have outsize impact on storm clouds, precipitation
    on January 25, 2018 at 7:09 pm

    Tiny particles fuel powerful storms and influence weather much more than has been appreciated, according to a new study. While scientists have known that aerosols may play an important role in shaping weather and climate, the new study shows that the smallest of particles have an outsize effect. The tiny pollutants -- long considered too small to have much impact on droplet formation -- are, in effect, diminutive downpour-makers. […]

  • Climate engineering, once started, would have severe impacts if stopped
    on January 22, 2018 at 8:07 pm

    Facing a climate crisis, we may someday spray sulfur dioxide into the upper atmosphere to form a cloud that cools the Earth, but suddenly stopping the spraying would have a severe global impact on animals and plants, according to the first study on the potential biological impacts of geoengineering, or climate intervention. […]

  • Michigan's sugar maples will struggle in a warmer, drier future despite help from nitrogen pollution
    on January 17, 2018 at 3:41 pm

    Though Michigan's sugar maples benefit from the growth-promoting effects of nitrogen compounds in the environment, those gains will not fully offset the added stresses of growing under a drier climate in the future, according to a new study. […]

  • High performance CNT catalyst relating to its electroconductivity
    on January 16, 2018 at 2:56 pm

    Biofuels were obtained from Jatropha Oil using carbon nanotube (CNT) catalyst, which showed efficient cracking activity. The performance was activated by the high stability, metal sites, acid sites, electroconductivity, and coking tolerance of CNT. Two cracking circulations were found in the hydroprocessing. Meanwhile, the sulphur-free process was eco-friendly. […]

  • Yeast may be the solution to toxic waste clean-up
    on January 8, 2018 at 2:37 pm

    About 46,000 nuclear weapons were produced during the Cold War era, leading to tremendous volumes of acidic radioactive liquid waste seeping into the environment. A new study suggests yeast as a potentially safer and more cost effective way to help clean up these radioactive waste sites. […]

  • Chemists discover plausible recipe for early life on Earth
    on January 8, 2018 at 2:01 pm

  • Freezing trees, finding answers
    on December 6, 2017 at 2:07 pm

    Ice storms can wreak havoc on communities. Frozen limbs, dragged down by the weight of the ice, can snap off and fall on cars, homes, and power lines. But scientists aren't sure how ice storms affect long-term forest health. Researchers are changing that. […]

  • Diesel vehicles in oil sands operations contribute to regional pollution
    on December 6, 2017 at 2:06 pm

    Wildfires, cigarette smoking and vehicles all emit a potentially harmful compound called isocyanic acid. The substance has been linked to several health conditions, including heart disease and cataracts. Scientists investigating sources of the compound have now identified off-road diesel vehicles in oil sands production in Alberta, Canada, as a major contributor to regional levels of the pollutant. […]

  • Raindrops splash pathogens onto crops
    on November 20, 2017 at 2:00 pm

    Pathogens, such as bacteria, viruses or fungi, cause harmful plant disease and often lead to the destruction of agricultural fields. With many possible dispersal methods, it can often be difficult to assess the damage of a pathogen’s impact before it’s too late. […]

  • Secrets of succulents' water-wise ways revealed
    on November 16, 2017 at 6:27 pm

  • China's sulfur dioxide emissions fell significantly while India's grew over last decade
    on November 9, 2017 at 2:32 pm

    Sulfur dioxide is an air pollutant that causes acid rain, haze and many health-related problems. It is produced predominantly when coal is burned to generate electricity. Although China and India remain the world's largest consumers of coal, a new study found that China's sulfur dioxide emissions fell by 75 percent since 2007, while India's emissions increased by 50 percent. […]

  • Late Triassic terrestrial ecosystem changes
    on October 26, 2017 at 5:53 pm

    The Norian Chinle Formation in the Southwestern United States provides a snapshot into an ancient terrestrial ecosystem with its famous petrified tree trunks and various plant and vertebrate remains. The fossil plant assemblages, including spores and pollen grains, provide useful information on past vegetation and the response of the vegetation to climate changes. […]

  • One of planet's largest volcanic eruptions
    on October 11, 2017 at 1:11 pm

    Researchers have determined that the Pacific Northwest was home to one of the Earth's largest known volcanic eruptions, a millennia-long spewing of sulfuric gas that blocked out the sun and cooled the planet. Only two other eruptions -- the basalt floods of the Siberian Traps and the Deccan Traps -- were larger, and they led to two of the Earth's great extinctions. […]

  • Study examines legacies of rainforest burning in British Columbia
    on September 25, 2017 at 5:30 pm

  • Biochar shows benefits as manure lagoon cover
    on August 9, 2017 at 6:02 pm

    Manure is a reality in raising farm animals. Manure can be a useful fertilizer, returning valued nitrogen, phosphorus, and potassium to the soil for plant growth. But manure has problems. Odor offensiveness, gas emissions, nutrient runoff, and possible water pollution are just a few. New methods may reduce these negatives while potentially adding some positives: biochar covers. […]

  • Biochar could clear the air in more ways than one
    on July 27, 2017 at 2:29 pm

    Biochar could reduce local air pollution from agriculture by reducing emissions of nitric oxide from soil. Researchers argue that a better understanding of nitric oxide response to biochar will save lives and money, especially on farms near urban areas where agricultural emissions contribute to ozone and particulate matter formation. […]
