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.

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.

Examining NYC storm surge infrastructure resilience
With the recent Hurricanes Harvey, Irma, and now Maria, which ravaged much of Texas, Florida, and Puerto Rico, as well as Hurricane Katrina and Superstorm Sandy, from which NYC infrastructure is still recovering, it has become clear that addressing threats to infrastructure is critical to keeping our communities safe, functional, and healthy. Storm surge has emerged as one of the most destructive forces on infrastructure, especially interconnected structures in cities.

Improving forecasts of hurricane strength
As Hurricane Irma approached U.S. shores, researchers sponsored by the Office of Naval Research (ONR) were using air-dropped autonomous sensors to compile real-time ocean observations to help forecasters predict the strength of future tropical storms. This marked the first time a new, specialized version of the sensors—called ALAMO (Air-Launched Autonomous Micro Observer) sensors—was being used in hurricane-prediction research.

No internet? No problem: Improving communications during natural disasters
Storms like Hurricane Irma and other natural disasters bring with them lots of uncertainty: where will they go, how much damage will they cause. What is certain is that no matter where they strike, natural disasters knock out power. And no power means no internet for thousands of people in affected areas. Researchers are proposing a new way of gathering and sharing information during natural disasters that does not rely on the internet.

Limiting warming to 1.5°C still possible
Significant emission reductions are required if we are to achieve one of the key goals of the Paris Agreement, and limit the increase in global average temperatures to 1.5°C; scientists say. A new study, investigating the geophysical likelihood of limiting global warming to “well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C,” concluded L limiting the increase in global average temperatures above pre-industrial levels to 1.5°C, the goal of the Paris Agreement on Climate Change, is not yet geophysically impossible, but likely requires more ambitious emission reductions than those pledged so far.

Economic costs of Harvey, Irma $200-$300 billion; insured cost to reach $70 billion
The insured cost of Hurricanes Harvey and Irma is likely to reach $70 billion, while the economic cost — which includes uninsured losses – is in the range of $200 billion to $300 billion, leading insurers say. Lloyd’s of London said the claims would make 2017 one of the worst years for natural disasters with the hurricane season not yet over.
