• Methods for protecting England’s coastal communities “not fit for purpose”

    In October 2018, a stark report suggested that current methods being used to protect England’s coastal communities are “not fit for purpose.” The Committee on Climate Change’s Managing the coast in a changing climate report showed that between 2005 and 2014, over 15,000 new buildings were built in coastal areas at significant risk of coastal flooding and/or erosion. Experts say that evidence suggests there should be far stricter controls on coastal developments.

  • More people are getting bigger, requiring more food

    Food demand is growing as people get bigger. Feeding a population of 9 billion in 2050 will require much more food than previously calculated. The number of people on Earth could level off at around nine billion in a few years, compared to just over 7.6 billion now. But an average person in the future will require more food than today. Changes in eating habits, attitudes towards food waste, increases in height and body mass, and demographic transitions are some of the reasons.

  • Severe Caribbean droughts would magnify food insecurity

    Climate change is impacting the Caribbean, with millions facing increasing food insecurity and decreasing freshwater availability as droughts become more likely across the region, according to new research. Since 1950, the Caribbean region has seen a drying trend and scattered multiyear droughts. But the recent Pan-Caribbean drought in 2013-16 was unusually severe and placed 2 million people in danger of food insecurity.

  • Bolstering resilience to withstand floods

    Historically, flooding is the most destructive natural disaster in this country. Facing this ever-growing threat, many wonder, “What can be done to protect life and property, reduce insurance claims, as well as help communities become more resilient?” DHS S&T has initiated multiple projects across the nation through its Flood Apex Program to offer an answer to this question.

  • Technologies to remove CO2 from air and sequester it key to climate change mitigation

    To achieve goals for climate and economic growth, “negative emissions technologies” (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change, says a new report from the National Academies of Sciences.

  • A dry future? New interactive map highlights water scarcity around the globe

    The average person in Europe uses 3,000−5,000 liters of water per day, of which the lion’s share is spent on food production. The world’s limited water resources are becoming an even more pressing issue as populations grow and climate change causes droughts in both south and north. Studies have already provided a number of ways to reduce our consumption of water, but this valuable information is often left unused.

  • Fracking-related water storage tied to earthquake risk

    In addition to producing oil and gas, the energy industry produces a lot of water, about 10 barrels of water per barrel of oil on average. New research has found that where the produced water is stored underground influences the risk of induced earthquakes.

  • World heritage sites under threat from climate change

    UNESCO World Heritage sites in the Mediterranean such as Venice, the Piazza del Duomo, Pisa, and the Medieval City of Rhodes are under threat of coastal erosion and flooding due to rising sea levels. The authors have identified areas with urgent need for adaptation planning and suggest the iconic nature of such sites can be used to promote awareness of the need to take action to mitigate climate change.

  • Climate change could cause global beer shortages

    Severe climate events could cause shortages in the global beer supply, according to new research. The study warns that increasingly widespread and severe drought and heat may cause substantial decreases in barley yields worldwide, affecting the supply used to make beer, and ultimately resulting in “dramatic” falls in beer consumption and rises in beer prices.

  • Geoengineering, other technologies won’t solve climate woes

    The countries of the world still need to cut their carbon dioxide emissions to reach the Paris Agreement’s climate targets. Relying on tree planting and alternative technological solutions such as geoengineering will not make enough of a difference.

  • Global hotspots for potential water conflicts

    Scientists at the Joint Research Center (JRC) of the European Commission have identified the hotspots where competition over the use of shared water resources could lead to disagreements between countries. The scientists determined that the Nile, Ganges-Brahmaputra, Indus, Tigris-Euphrates and Colorado rivers are “water hotspots”, where “hydro-political interactions” are most likely to occur. These areas are already under water stress, and future demographic and climatic conditions are expected to exert further pressure on scarce water resources.

  • The 1800s Global Famine could happen again

    Researchers have completed the most thorough analysis yet of The Great Drought — the most devastating known drought of the past 800 years — and how it led to the Global Famine, an unprecedented disaster that took 50 million lives. She warns that the Earth’s current warming climate could make a similar drought even worse.

  • Florida Panhandle counties less prepared for emergency than rest of state

    found that the vast majority of counties in the Florida Panhandle were less prepared for emergency evacuation compared to the rest of the state. Of the 67 counties in Florida, 10 were rated as having weak levels of evacuation preparedness, and all of these counties were located in the Panhandle/North Florida. Eleven of 16 counties with moderately rated plans also were in this region. Only seven of the counties in the Panhandle had strong plans.

  • Hurricane Michael damage could be worst in decades: Florida governor

    Hurricane Michael is intensifying into a Category 4 storm as it speeds toward Panama City on the Florida Panhandle. Heavy rains and strong winds have started after tens of thousands of residents evacuated. Experts had been warning residents to evacuate – but at about 11:00 am Wednesday, Florida authorities said that those residents who had not yet evacuated should barricade themselves in their homes. Falling trees, collapsed powerlines, and rising water would likely strand residents on the road if they left their homes now, so they would be safer staying put.

  • Civil engineering professor urges Midwest tornado preparation

    Researchers rely on a pair of analytical observations more commonly invoked in fields such as cognitive psychology, economics or political science — prospect theory and game theory — to make Tornado Alley safer. The unofficial geographic designation encompasses Texas, Oklahoma, Kansas, Iowa, Missouri, and other parts of the central United States.
