    New research shows human-induced climate change increased the amount and intensity of Hurricane Harvey's unprecedented rainfall. […]

  • Birth of a storm in the Arabian Sea validates climate model
    on December 6, 2017 at 7:16 pm

    Extreme cyclones that formed in the Arabian Sea for the first time in 2014 are the result of global warming and will likely increase in frequency, warn scientists. Their model showed that the burning of fossil fuels since 1860 would lead to an increase in the destructive storms in the Arabian Sea by 2015, marking one of the first times that modeled projections have synchronized with real observations of storm activity. […]

  • Freezing trees, finding answers
    on December 6, 2017 at 2:07 pm

    Ice storms can wreak havoc on communities. Frozen limbs, dragged down by the weight of the ice, can snap off and fall on cars, homes, and power lines. But scientists aren't sure how ice storms affect long-term forest health. Researchers are changing that. […]

  • Beyond wind speed: A new measure for predicting hurricane impacts
    on December 5, 2017 at 5:00 pm

    What if there was a better way to forecast and communicate hurricanes' damaging economic impacts, before they happen? Civil engineers have developed an innovative new approach to assessing the resiliency of coastal communities to hurricanes. They've created a 'multi-hazard hurricane impact level model,' which estimates economic damages to be caused by storms, before they happen. […]

  • Off track: How storms will veer in a warmer world
    on November 15, 2017 at 5:49 pm

    The dry, semi-arid regions are expanding into higher latitudes, and temperate, rainy regions are migrating poleward. In a new paper, researchers provide new insight into this phenomenon by discovering that mid-latitude storms are steered further toward the poles in a warmer climate. […]

  • Texas' odds of Harvey-scale rainfall to increase by end of century
    on November 13, 2017 at 8:38 pm

    Texas' risk of Harvey-scale rainfall will increase by the end of this century, new research concludes. By 2100, the annual probability of Hurricane Harvey's record rainfall returning to Texas will rise to 18 percent, if the growth of greenhouse gas emissions continues unmitigated. […]

    on November 8, 2017 at 2:20 pm

    New research provides a physical understanding for why central pressure deficit is a better indicator of economic damage from hurricanes than peak wind speed. […]

  • Sea-level rise, not stronger storm surge, will cause future NYC flooding
    on October 23, 2017 at 10:25 pm

    Rising sea levels caused by a warming climate threaten greater future storm damage to New York City, but the paths of stronger future storms may shift offshore, changing the coastal risk for the city, according to a team of climate scientists. […]

  • Warming seas could lead to 70 percent increase in hurricane-related financial loss
    on October 12, 2017 at 7:18 pm

    Hurricane-related financial loss could increase more than 70 percent by 2100 if oceans warm at the worst-case-scenario rate predicted by the Intergovernmental Panel on Climate Change, according to a new study. The study used a combination of hurricane modeling and information in FEMA's HAZUS database to reach its conclusions. […]

    on October 12, 2017 at 4:39 pm

    Those who are afraid of thunderstorms should move to Kiel, whereas those who do not feel threatened by thunder and lightning should settle in Garmisch-Partenkirchen, because average thunderstorm activity is lowest in the city in Northern Germany and highest in the city in Bavaria, report scientists who evaluated data on thunderstorm occurrences. […]

  • Rainfall trends in arid regions buck commonly held climate change theories
    on October 12, 2017 at 4:30 pm

    To explore the links between climatic warming and rainfall in drylands, scientists analysed more than 50 years of detailed rainfall data (measured every minute) from a semi-arid drainage basin in south east Arizona exhibiting an upward trend in temperatures during that period. […]

    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. […]

    on October 5, 2017 at 7:11 pm

    The 2017 hurricane season has highlighted the critical need to communicate a storm's impact path and intensity accurately, but new research shows significant misunderstandings of the two most commonly used storm forecast visualization methods. […]

  • 12,000 years ago, Florida hurricanes heated up despite chilly seas
    on October 5, 2017 at 4:50 pm

    Category 5 hurricanes may have slammed Florida repeatedly during the chilly Younger Dryas, 12,000 years ago. The cause? Hurricane-suppressing effects of cooler sea surface were out-weighed by side effects of slowed ocean circulation. […]

  • 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. […]

  • Hurricane Harvey may have worsened beach erosion
    on September 20, 2017 at 3:48 pm
