• Globe had 2nd warmest year to date, 4th warmest September on record

    The average global temperature set in September 2017 was 1.40 degrees F above the 20th-century average of 59.0 degrees. This average temperature was the fourth highest for September in the 1880-2017 record. This marked the 41st consecutive September and the 393rd consecutive month with temperatures above the 20th-century average. The year-to-date average temperature was 1.57 degrees F above the 20th-century average of 57.5 degrees. Arctic and Antarctic sea ice coverage remains small.

  • Warming seas could lead to 70 percent increase in hurricane-related financial loss

    If oceans warm at a rate predicted by the Intergovernmental Panel on Climate Change, the UN-sponsored group that assesses climate change research and issues periodic reports, expected financial losses caused by hurricanes could increase more than 70 percent by 2100, according to researchers. The finding is based on the panel’s most severe potential climate change scenario – and resulting increased sea surface temperature – and is predicted at an 80 percent confidence level. The model drew on hurricane data for the last 150 years gathered by NOAA.

  • NOAA-funded effort to better predict droughts

    On average, droughts cost an estimated $9 billion in damages every year in the United States, according to NOAA. A single drought in 2012, which spread across the U.S. and brought very dry conditions to Michigan, caused some $32 billion in damage nationwide, mostly due to widespread harvest failure. Scientists work to develop a better system to predict droughts.

  • Houston officials let developers build homes inside reservoirs. But no one warned buyers.

    Hurricane Harvey forced many Houston-area residents to realize that their homes were built inside the two massive reservoirs which had been built west of Houston decades ago to protect the city from catastrophic flooding. These homeowners are now coming to terms with the fact that in big enough rainstorms, their neighborhoods are actually designed to flood. Trouble is, nobody told them about it. Today, about 14,000 homes are located inside the reservoirs, or “flood pools,” as city planners call them.

  • Psychology holds key to getting people out before disaster strikes

    Natural disasters are becoming more frequent and intense. Recent hurricanes, floods, bushfires and earthquakes have highlighted the significant potential for mass trauma. Yet we know relatively little about the psychology of decision-making in dangerous conditions. Evacuation is a key strategy for keeping city residents safe. Yet our study identifies several barriers to evacuation in high-density cities. Importantly, psychological factors could affect decision-making in these situations.

  • This is only a Test: Asteroid tracking network observes close approach

    Yesterday, 12 October 2017, a small asteroid designated 2012 TC4 safely passed by Earth at a distance of approximately 26,000 miles (42,000 kilometers). This is a little over one tenth the distance to the Moon and just above the orbital altitude of communications satellites. This encounter with TC4 was being used by asteroid trackers around the world to test their ability to operate as a coordinated international asteroid warning network.

  • Wildfires create much more pollution than previously thought

    Naturally burning timber and brush launch what are called fine particles into the air at a rate three times as high as levels officially noted in emissions inventories at the U.S. Environmental Protection Agency, according to a new study. This does not mean that burning biomass produces more pollution than it previously did, but the new research makes clearer how much and what pollutants are inside a wildfire plume. Fine particles, the microscopic, sooty specks that form aerosols, are a hazard to human health, particularly to the lungs and heart.

  • After hurricanes, Congress ponders future of flood insurance program

    The devastating hit Houston took from Hurricane Harvey has exacerbated — and highlighted — the enormous financial jam facing the National Flood Insurance Program. Thanks to the recent onslaught of hurricanes hitting Texas, Florida and Puerto Rico, there has never been a greater need for the program. But that need has also set off a new round of calls to dramatically overhaul a program that hasn’t been able to sustain itself without major subsidies from the U.S. Treasury.

  • Advancing the accuracy of hurricane storm surge forecasts

    Of the thirteen named storms so far this season, eight have been hurricanes, with five of the eight — Harvey, Irma, Jose, Lee, and Maria — reaching Category 3 or higher. Storm surge — how high ocean waters rise and where flooding occurs —  is often the greatest threat to life and property during a tropical cyclone. A single storm can devastate livelihoods and cause tens of billions of dollars in damage.

  • Mass casualty incidents and the overlap between trauma systems and hospital disaster preparedness

    A single patient with a gunshot wound (GSW) to a vital body part (e.g., head, chest, abdomen, or major artery) will stress a typical community hospital. The more than 500 people who were injured in Las Vegas on 1 October have been transported to a number of hospitals around Las Vegas and have overwhelmed some of the hospitals closest to the scene. A number of the injured are in critical condition and hence the death toll is likely to rise. Among other issues, this tragedy illustrates the overlap between trauma systems and hospital disaster preparedness.

  • USGS helps four cities improve urban waterways

    This fall more than $1.5 million is being invested in improving urban lands and waters thanks to expanded USGS partnerships with Albuquerque, New Mexico; San Antonio, Texas; Gary, Indiana; and Harlem and Bronx, New York.

  • Hurricane loss model estimates damage caused by Hurricane Irma at $19 billion

    A team of researchers estimates that Hurricane Irma caused $19.4 billion in wind-related losses to Florida residents alone. The data does not cover flood losses. Of that total, $6.3 billion will be paid by insurance companies. As a result, roughly two-thirds of the losses will be borne by homeowners.

  • AI, citizen science, disaster response combine to help Hurricane Irma’s victims

    A highly unusual collaboration between information engineers at Oxford, the Zooniverse citizen science platform, and international disaster response organization Rescue Global is enabling a rapid and effective response to Hurricane Irma. The project draws on the power of the Zooniverse, the world’s largest and most popular people-powered research platform, to work with volunteers and crowd source the data needed to understand Irma’s path of destruction and the damage caused.

  • Drones could save lives in disaster zones

    Research from the University of South Australia has shown for the first time that drones can be used to detect human vital signs in war zones and natural disasters. The researchers have successfully trialed unmanned aerial vehicles to measure heart and respiratory rates using remote-sensing imaging systems, while hovering three meters from humans.

  • Testing bridges for safety after major hurricanes

    After Hurricane Irma hit, there was a major concern about South Florida’s bridges, mainly the ones in the Florida Keys. Would the structures be safe to cross for drivers anxious to get back home? Would relief efforts be impaired due to damage caused by massive winds? Fortunately, all forty-two bridges that connect the mainland to the Keys were inspected and declared safe by Monroe County officials. If another major hurricane like Irma hits South Florida, researchers and engineers shares an easy and cost-effective way to test a bridge for safety.
