• Unabated climate change would reverse the development gains in Asia: report

    Unabated climate change would bring devastating consequences to countries in Asia and the Pacific, which could severely affect their future growth, reverse current development gains, and degrade quality of life, according to a report produced by the Asian Development Bank (ADB) and the Potsdam Institute for Climate Impact Research (PIK).

  • Severe weather model predicted tornado's path hours before it formed

    As severe weather brewed in the Texas panhandle late in the afternoon of May 16,  NOAA’s National Weather Service forecasters alerted residents in parts of western Oklahoma about the potential for large hail and damaging tornadoes that evening, particularly in the area around Elk City.

    Ninety minutes later, a dangerous, rain-wrapped EF2 tornado struck the small town. It killed one, injured eight and destroyed about 200 homes and more than 30 businesses.

  • Getting to the roots of Sahara mustard invasion in the American Southwest

    In 2015, a rural community in southeastern California approached Daniel Winkler and his doctoral advisor, Travis Huxman, for help with an invader that was hurting their local economy. An Old World annual plant called Sahara mustard (Brassica tournefortii) was spreading rapidly through the deserts of the southwestern U.S., carpeting the local Anza-Borrego Desert in spring, and smothering the native wildflowers that draw tourists to the region. Loss of native plants put the animals that depend on them for food and shelter at risk. The mustard was disrupting the entire desert ecosystem.

  • Climate change could mean more weight restrictions and higher costs for airlines

    As air temperatures rise at constant pressure, the density of air declines and this makes it harder for an airplane to take off. Increased air temperatures due to climate change could therefore present a new challenge for the aviation industry. This is according to Ethan Coffel of Columbia University in the US, lead author of a study in Climatic Change Letters which is a section in Springer’s journal Climatic Change

  • Study suggests route to improving rechargeable lithium batteries

    Most of today’s lithium-ion batteries, which power everything from cars to phones, use a liquid as the electrolyte between two electrodes. Using a solid electrolyte instead could offer major advantages for both safety and energy storage capacity, but attempts to do this have faced unexpected challenges.

  • Study Finds Toxic Mercury is Accumulating in the Arctic Tundra

    Vast amounts of toxic mercury are accumulating in the Arctic tundra, threatening the health and well-being of people, wildlife and waterways, according to a UMass Lowell scientist investigating the source of the pollution. 

    A research team led by Prof. Daniel Obrist, chairman of UMass Lowell’s Department of Environmental, Earth and Atmospheric Sciences, found that airborne mercury is gathering in the Arctic tundra, where it gets deposited in the soil and ultimately runs off into waters. Scientists have long reported high levels of mercury pollution in the Arctic. The new research identifies gaseous mercury as its major source and sheds light on how the element gets there.

  • New biofuel technology cuts production time significantly

    New research from a professor of engineering at UBC’s Okanagan Campus might hold the key to biofuels that are cheaper, safer and much faster to produce.

    “Methane is a biofuel commonly used in electricity generation and is produced by fermenting organic material,” says Cigdem Eskicioglu, an associate professor with UBC Okanagan’s School of Engineering. “The process can traditionally take anywhere from weeks to months to complete, but with my collaborators from Europe and Australia we’ve discovered a new biomass pretreatment technique that can cut production time nearly in half.”

  • Chillier Winters, Smaller Beaks

    Although Charles Darwin lived and worked in the 19th century, modern evolutionary biologists are far from exhausting all avenues of inquiry regarding birds and evolution. For example, in the 1990s, researchers such as Russ Greenberg, ornithologist from the Smithsonian Institution in the United States, began to explore a new question concerning the relationship between climate and the evolution of beak size. This question was inspired by Allen’s Rule, which states that warm-blooded animals living in cold climates will have shorter limbs and appendages than those that live in warmer climates. The biological mechanism behind this rule is thermoregulation—more body surface area helps animals to shed heat better whereas less surface area helps them to conserve it. Since a bird’s beak plays a large role in thermoregulation—it has lots of blood vessels and is not covered in feathers—researchers wondered whether hotter climates beget larger beaks and colder climates beget smaller ones. Indeed, studies revealed that climate has influenced beak size, but not which type of climate had more of an overall impact.
