  • Cool roofs have water saving benefits too
    on October 20, 2017 at 1:22 pm

    The energy and climate benefits of cool roofs have been well established: By reflecting rather than absorbing the sun's energy, light-colored roofs keep buildings, cities, and even the entire planet cooler. Now a new study has found that cool roofs can also save water by reducing how much is needed for urban irrigation. […]

    on October 12, 2017 at 3:48 pm

    While strong seasonal hurricanes have devastated many of the Caribbean and Bahamian islands this year, geologic studies on several of these islands illustrate that more extreme conditions existed in the past. A new analysis shows that the limestone islands of the Bahamas and Bermuda experienced climate changes that were even more extreme than historical events. […]

  • Stepped care beneficial after hurricanes
    on October 10, 2017 at 4:38 pm

    Stepped care is more effective than usual care in reducing the prevalence of posttraumatic stress disorder in the aftermath of hurricanes, according to a new study. […]

  • Forest grazing counteracts the effectiveness of trees to reduce flood risk
    on October 10, 2017 at 3:46 pm

    Planting trees can reduce flood risk, but a high intensity forest land use, such as grazing, can counteract the positive effect of the trees, a recently published study suggests. The study investigated the rate that water infiltrated the soil under trees at an experimental agroforestry site in Scotland. […]

  • Droughts and wildfires: How global warming is drying up the North American monsoon
    on October 9, 2017 at 4:31 pm

    Previous researchers had concluded that global warming was simply delaying the North American monsoon, which brings summer rains to the southwestern US and northwestern Mexico. But a new, high-resolution climate model that corrects for persistent sea surface temperature (SST) biases now accurately reflects current rainfall conditions and demonstrates that the monsoon is not simply delayed, but that the region's total rainfall is facing a dramatic reduction. […]

    Marine biologists have released estimates of sea turtle nests lost to Hurricane Irma, finding that 56 percent of green turtle nests and 24 percent of loggerhead nests were lost within Archie Carr National Wildlife Refuge. Both are endangered species. The losses put a damper on what had been a record year for green turtle nesting. […]

  • Extreme magnetic storm: Red aurora over Kyoto in 1770
    on October 3, 2017 at 3:10 pm

    Researchers used historic accounts of a rare red aurora over Kyoto, Japan, in the 18th century to support calculations of the strength of the associated magnetic storm. The September 1770 storm could be 3-10% stronger than the September 1859 storm, the greatest storm in the past 200 years. The research provides insights that could assist preparation for an unlikely, but possible, future intense magnetic storm. […]
