• Humanity’s Ability to Feed Itself Under Growing Threat

    A new UN report warns that the world’s land and water resources are being exploited at “unprecedented rates,” and that the combination of this increasingly more rapid exploitation with climate change is putting dire – and threatening — pressure on the ability of mankind to feed itself.

  • DoD “Precariously Underprepared” for Security Challenges of Climate Change

    The United States Army War College recently released a report exploring the broad impact climate change will have on national security and U.S. Army operations, and offering what it describes as urgent recommendations. The second sentence of the report captures the report’s tone and argument: “The Department of Defense is precariously underprepared for the national security implications of climate change-induced global security challenges.”

  • U.S. Infrastructure Unprepared for Increasing Frequency of Extreme Storms

    Current design standards for United States hydrologic infrastructure are unprepared for the increasing frequency and severity of extreme rainstorms, meaning structures like retention ponds and dams will face more frequent and severe flooding, according to a new study.

  • July Equaled, or Even Surpassed, the Hottest Month in Recorded History

    July at least equaled, if not surpassed, the hottest month in recorded history. This follows the warmest ever June on record. The figures show that, based on the first 29 days of the month, July 2019 will be on par with, and possibly marginally warmer than the previous warmest July, in 2016, which was also the warmest month ever. The latest figures are particularly significant because July 2016 was during one of the strongest occurrence of the El Niño phenomenon, which contributes to heightened global temperatures. Unlike 2016, 2019 has not been marked by a strong El Niño.

  • Predicting Storm Surges, Flooding, and Tides to Help Coastal Communities

    When weather systems threaten the coast, emergency responders rely on high-precision storm modeling systems and real-time data to accurately predict hurricane activity and flooding threats, collaborate with each other, and make critical decisions that will protect the lives and property of millions of U.S. residents. During the 2018 hurricane season, the ADCIRC Prediction System (APS) played an integral role in accurately predicting the storm surges, flooding, wind and wave interactions, and speed of tides and currents associated with both Florence and Michael.

     

  • Improving Security of Nuclear Materials Transportation

    Nuclear power plants can withstand most inclement weather and do not emit harmful greenhouse gases. However, trafficking of the nuclear materials to furnish them with fuel remains a serious issue as security technology continues to be developed. Physicists conducted research to enhance global nuclear security by improving radiation detectors. According to them, improving radiation detectors requires the identification of better sensor materials and the development of smarter algorithms to process detector signals.

  • Predicting Earthquake Hazards from Wastewater Injection

    A byproduct of oil and gas production is a large quantity of toxic wastewater called brine. Well-drillers dispose of brine by injecting it into deep rock formations, where its injection can cause earthquakes. Most quakes are relatively small, but some of them have been large and damaging. Yet predicting the amount of seismic activity from wastewater injection is difficult because it involves numerous variables. Geoscientists have developed a method to forecast seismic hazards caused by the disposal of wastewater.

  • What Will Communities Do When the Water Runs Dry?

    Earlier this summer, the sixth-largest city in India, Chennai, ran out of water. Water crises are now global. Cape Town, South Africa, narrowly escaped Day Zero last year, but it’s still at risk, as are Sao Paulo and Mexico City. Iraq, Morocco and Spain also face water shortages. “What we are seeing in Chennai right now is a devastating illustration of human-driven climate disruption,” says an expert. “It is hard for me to picture a near future where access to clean, fresh water continues in as plentiful a way as it is in most of our country at this moment.”

  • Worst Rainfall in 150 Years Damages Pennsylvania Homes, Roads

    According to the 150 years of data used by the National Weather Service, 2018 was the wettest year in the Berks region of Pennsylvania, with 68.08 inches of precipitation measured at Reading Regional Airport. This year is ahead of last year’s pace, with 38.21 inches already, far above the normal rate of 24.18 inches. Records for the wettest 12-month period are being set each month, according to the weather service. Some municipal officials say their infrastructure and stormwater management systems can’t handle the amount of rain we’re now receiving, and they are trying to figure out what type of improvements they can afford.

  • Jakarta’s Giant Sea Wall Is Useless If the City Keeps Sinking

    Late last week, president Joko Widodo of Indonesia told the AP that he’s fast-tracking a decade-in-the-making plan for a giant sea wall around Jakarta, a city that’s sinking as much as 8 inches a year in places—and as seas rise, no less. Models predict that by 2050, a third of the city could be submerged. It’s an urban existential crisis the likes of which the modern world has never seen.

  • Innovative Approach to Flood Mapping Supports Emergency Management, Water Officials

    Dependable, detailed inundation estimates are vital for emergency managers to have enough situational awareness to quickly get the right resources and information to flood-impacted communities. In 2007, severe flooding in southeastern Kansas put a spotlight on the lack of timely, reliable projections for floodwater spread.

  • Climate Change, Population Growth Worsen North Carolina Coastal Flooding

    A historic 120-year-old data set is allowing researchers to confirm what data modeling systems have been predicting: climate change is increasing precipitation events like hurricanes, tropical storms and floods. Researchers found that six of the seven highest precipitation events in the record have occurred within the last 20 years, according to the study.

     

  • Texas might spend up to $20 billion to protect Houston from hurricanes. Rice University says it can do it for a fraction of that.

    A government plan to guard the Houston-Galveston region from deadly storm surge could cost as much as $20 billion and isn’t expected to become reality for at least 15 years. Rice University says it has a plan that could be completed faster for a fraction of the cost.

  • Hackers’ Latest Target: School Districts

    Some hackers demand ransom; others sweep up personal data for sale to identity thieves. But whatever hackers’ motives, school systems around the country have been the targets of their cyberattacks. Nearly two-thirds of school districts in the United States serve fewer than 2,500 students, and many do not have a staff member dedicated solely to cybersecurity.

  • Upholding Scientific Integrity at Federal Agencies

    Republicans and Democrats on a House subcommittee on Thursday agreed that science-related policy decisions should be based on facts, but differed on how to protect the federal scientists who gather and analyze those facts from undue influence.
