• Algal Toxins Detected in One-Third of Streams Assessed in Southeastern United States

    USGS scientists have detected toxins known as microcystins produced by various forms of algae in 39 percent of the small streams assessed throughout the southeastern United States. Their recent study looked at 75 streams in portions of Alabama, Georgia, North Carolina, South Carolina and Virginia.

  • New Report Ties "Hottest Year on Record" to Human Toll of Disasters

    Natural disasters made 2015 a miserable year for many people around the world. According to the United Nations’ Office for Disaster Risk Reduction, the statistics were brutal. At least 98.6 million people were affected by natural disasters ranging from droughts to floods, and the economic damage could have been as high as $66.5 billion. Using the data available from the Belgian non-profit Center for Research on the Epidemiology of Disasters (CRED), the UN reports that almost 23,000 people died from the 346 natural disasters reported across the world.

  • Land surfaces are storing more water slowing sea level rise

    New measurements from a NASA satellite have allowed researchers to identify and quantify, for the first time, how climate-driven increases of liquid water storage on land have affected the rate of sea level rise.

    A new study by scientists at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, and the University of California, Irvine, shows that while ice sheets and glaciers continue to melt, changes in weather and climate over the past decade have caused Earth's continents to soak up and store an extra 3.2 trillion tons of water in soils, lakes and underground aquifers, temporarily slowing the rate of sea level rise by about 20 percent.

    The water gains over land were spread globally, but taken together they equal the volume of Lake Huron, the world's seventh largest lake. The study is published in the Feb. 12 issue of the journal Science.

  • Carbon dioxide stored underground can find multiple ways to escape

    When carbon dioxide is stored underground in a process known as geological sequestration, it can find multiple escape pathways due to chemical reactions between carbon dioxide, water, rocks and cement from abandoned wells, according to Penn State researchers.

  • Climate change will delay transatlantic flights

    Planes flying between Europe and North America will be spending more time in the air due to the effects of climate change, a new study has shown.

    By accelerating the jet stream – a high-altitude wind blowing from west to east across the Atlantic – climate change will speed up eastbound flights but slow down westbound flights, the study found.  The findings could have implications for airlines, passengers, and airports.

  • Over 50 Percent of the World Breathes in Toxic Air

    Everyone needs clean air to survive, yet somehow it is not an internationally recognized human right. That probably has something to do with the fact that over half of the world’s population live in areas where they breathe in toxic air. Altogether, that means there are more than 3.5 billion people inhaling dangerous air into their lungs on a daily basis.

  • Disease may wipe out the world's bananas

    Bananas are at the sharp end of industrial agriculture's chemical war on pests and pathogens, writes Angelina Sanderson Bellamy. But even 60 pesticide sprays a year isn't enough to keep the diseases at bay. It's time to seek new solutions with little or no use of chemicals, working with nature, growing diverse crops on the same land - and breaking the dominance of the banana multinationals.

  • Man-made underwater sound may have wider ecosystem effects than previously thought

    Underwater sound linked to human activity could alter the behaviour of seabed creatures that play a vital role in marine ecosystems, according to new research from the University of Southampton.

    The study, reported in the journal Scientific Reports published by Nature, found that exposure to sounds that resemble shipping traffic and offshore construction activities results in behavioural responses in certain invertebrate species that live in the marine sediment.

  • Kalligrammatid lacewings looked like butterflies, but lived millions of years before butterflies

    New fossils found in Northeastern China have revealed a remarkable evolutionary coincidence: an extinct group of insects known as Kalligrammatid lacewings (Order Neuroptera) share an uncanny resemblance to modern day butterflies (Order Lepidoptera). Even though they vanished some 50 million years before butterflies appeared on earth, they possess the same wing shape and pigment hues, wing spots and eyespots, body scales, long proboscides, and similar feeding styles as butterflies.

    A photo of the modern owl butterfly (“Caligo Memnon”) shown beside a fossilized Kalligrammatid lacewing (“Oregramma illecebrosa”) shows some of the convergent features independently evolved by the two distantly-related insects, including wing eyespots and wing scales. (Butterfly photo by James Di Loreto/fossil photo by Conrad Labandeira and Jorge Santiago-Blay)

    In an incredible example of convergent evolution, both butterflies and kalligrammatids evol

  • Loss of wild flowers matches pollinator decline

    The first Britain-wide assessment of the value of wild flowers as food for pollinators shows that decreasing resources mirror the decline of pollinating insects.
