  • What drives public opinion on climate change?

    Updated: 2012-02-06 16:31:20
    Public concern about climate change has varied widely over the past few decades. For example, Gallup has been polling individuals about how much they personally worry about climate change. In 2004, 26 percent of the respondents stated that they worried "a great deal." By 2007, this proportion had risen to 41 percent. But by 2010, this fraction dropped to 28 percent. Why?read more

  • Political leaders play key role in how worried Americans are by climate change

    Updated: 2012-02-06 16:30:39
    COLUMBUS, Ohio – More than extreme weather events and the work of scientists, it is national political leaders who influence how much Americans worry about the threat of climate change, new research finds. In a study of public opinion from 2002 to 2010, researchers found that public belief that climate change was a threat peaked in 2006-2007 when Democrats and Republicans in Congress showed the most agreement on the issue. But public concern has dropped since then, as partisanship over the issue increased.read more

  • The effect of occasional binge drinking on heart disease and mortality among moderate drinkers

    Updated: 2012-02-02 15:31:00
    Most studies have found that binge drinking is associated with a loss of alcohol's protective effect against ischemic heart disease (IHD) and most studies have found an increase of coronary risk among binge drinkers. This study followed 26,786 men and women who participated in the Danish National Cohort Study in 1994, 2000, and 2005 and sought to see if binge drinking increased the risk of IHD or all-cause mortality among "light-to-moderate" drinkers: (up to 21 drinks/week for men and up to 14 drinks/week for women). A "drink" was 12g.read more

  • Heat and cold damage corals in their own ways, Scripps study shows

    Updated: 2012-02-02 15:02:00
    Around the world coral reefs are facing threats brought by climate change and dramatic shifts in sea temperatures. While ocean warming has been the primary focus for scientists and ocean policy managers, cold events can also cause large-scale coral bleaching events. A new study by scientists at Scripps Institution of Oceanography at UC San Diego compared damage to corals exposed to heat as well as cold stress. The results reveal that cool temperatures can inflict more damage in the short term, but heat is more destructive in the long run.read more

  • Global experts question claims about jellyfish populations

    Updated: 2012-02-01 20:31:07
    (Santa Barbara, Calif.) –– Blooms, or proliferation, of jellyfish have shown a substantial, visible impact on coastal populations — clogged nets for fishermen, stinging waters for tourists, even choked intake lines for power plants — and recent media reports have created a perception that the world's oceans are experiencing increases in jellyfish due to human activities such as global warming and overharvesting of fish.read more

  • JILA scientists confirm first 'frequency comb' to probe ultraviolet wavelengths

    Updated: 2012-02-01 18:31:47
    BOULDER, Colo. – Physicists at JILA have created the first "frequency comb" in the extreme ultraviolet band of the spectrum, high-energy light less than 100 nanometers (nm) in wavelength. Laser-generated frequency combs are the most accurate method available for precisely measuring frequencies, or colors, of light. In reaching the new band of the spectrum, the JILA experiments demonstrated for the first time a very fine mini-comb-like structure within each subunit, or harmonic, of the larger comb, drastically sharpening the measurement tool.read more

  • Tropical cyclones to cause greater damage

    Updated: 2012-02-01 16:00:56
    Tropical cyclones will cause $109 billion in damages by 2100, according to Yale and MIT researchers in a paper published in Nature Climate Change. That figure represents an increased vulnerability from population and especially economic growth, as well as the effects of climate change. Greater vulnerability to cyclones is expected to increase global tropical damage to $56 billion by 2100—double the current damage—from the current rate of $26 billion per year if the present climate remains stable.read more
