  • Sanchi oil spill contamination could take three months to reach mainland
    on January 13, 2018 at 2:37 pm

    Water contaminated by the oil currently leaking into the ocean from the Sanchi tanker collision is likely to take at least three months to reach land, and if it does the Korean coast is the most likely location. However, the oil's fate is highly uncertain, as it may burn, evaporate, or mix into the surface ocean and contaminate the environment for an extended duration. […]

  • Babies stir up clouds of bio-gunk when they crawl
    on January 11, 2018 at 7:09 pm

    When babies crawl, their movement across floors, especially carpeted surfaces, kicks up high levels of dirt, skin cells, bacteria, pollen, and fungal spores, a new study has found. The infants inhale a dose of bio bits in their lungs that is four times (per kilogram of body mass) what an adult would breathe walking across the same floor. […]

  • Noise from oil and gas operations stresses birds, hinders reproduction
    on January 9, 2018 at 4:24 pm

    Birds exposed to constant noise from oil and gas operations show physiological signs of chronic stress, have chicks whose growth is stunted, and -- in some cases -- lay fewer eggs that hatch, according to a new study. […]

    on January 9, 2018 at 4:24 pm

    Smoke plumes emanating from wildfires are swept high up into the air and spread over thousands of kilometers even days after a fire has been put out. The fine particles and harmful ozone contained in these plumes often have devastating effects on the air quality of US cities and consequently the health of their inhabitants. […]

  • The ocean is losing its breath -- here's the global scope
    on January 4, 2018 at 8:35 pm

    In the past 50 years, the amount of water in the open ocean with zero oxygen has gone up more than fourfold. In coastal water bodies, including estuaries and seas, low-oxygen sites have increased more than tenfold since 1950. Scientists expect oxygen to continue dropping even outside these zones as Earth warms. […]

  • We need one global network of 1000 stations to build an Earth observatory
    on January 4, 2018 at 5:03 pm

    Scientists call for a continuous, comprehensive monitoring of interactions between the planet's surface and atmosphere. […]

  • Researchers use 'global thermometer' to track temperature extremes, droughts
    on January 3, 2018 at 5:30 pm

    Large areas of Earth's surface are experiencing rising maximum temperatures, which affect virtually every ecosystem on the planet, including ice sheets and tropical forests that play major roles in regulating the biosphere, scientists have reported. […]

  • Arctic clouds highly sensitive to air pollution
    on January 3, 2018 at 3:11 pm

    A study by atmospheric scientists has found that the air in the Arctic is extraordinarily sensitive to air pollution, and that particulate matter may spur Arctic cloud formation. These clouds can act as a blanket, further warming an already-changing Arctic. […]

  • The Caribbean is stressed out
    on December 28, 2017 at 10:06 pm

    Forty percent of the world's 7.6 billion people live in coastal cities and towns. A team of marine biologists just released 25 years of data about the health of Caribbean coasts. The study provides new insights into the influence of both local and global stressors in the basin, and some hope that the observed changes can be reversed by local environmental management. […]

  • Cleaner air, longer lives
    on December 26, 2017 at 3:50 pm

  • Increased air pollution linked to bad teenage behavior
    on December 13, 2017 at 7:37 pm

    A new study linking higher levels of air pollution to increased teenage delinquency is a reminder of the importance of clean air and the need for more foliage in urban spaces. The study suggests ambient air pollution may increase delinquent behavior among 9- to 18-year-olds in urban neighborhoods in Greater Los Angeles. The insidious effects are compounded by poor parent-child relationships and parental mental and social distress, researchers report. […]
