• Urban Development and Greenhouses Gasses Will Fuel Urban Floods

    When rain began falling in northern Georgia on September 15, 2009, little did Atlantans know that they would witness epic flooding throughout the city. Researchers are asking whether a combination of urban development and climate change fueled by greenhouse gasses could bring about comparable scenarios in other U.S. cities. Based on a new study, the answer is yes.

  • How Do Floods Become a Disaster?

    Since the 1990s, the number of fatalities from river floods has declined worldwide, but the amount of damage has risen sharply. Researchers attribute the decline in casualties to improved flood warning, technical protection measures and heightened hazard awareness.

  • It’s Official: July Was Earth’s Hottest Month on Record

    New global data show that July was the world’s hottest month ever recorded. The combined land and ocean-surface temperature was 1.67 degrees F (0.93 of a degree C) above the 20th-century average of 60.4 degrees F (15.8 degrees C), making it the hottest July since records began 142 years ago.

  • Flood Risks in Germany Were Clearly Underestimated

    Expert say that to better estimate flood risks, risk maps should also consider historical data. The floods which devastated Rhineland-Palatinate and North Rhine-Westphalia caused 15 confirmed deaths, with more than two dozen people still unaccounted for. The damage is estimated at more than EUR 10 billion.

  • Middle-Class Residents Prefer to Stay Put after Floodwaters Recede

    Flood disasters lead some people to move far from the places they had called home. A new study finds that middle-class people who made long-term plans to stay in their neighborhoods before they flooded are less likely to relocate even if they suffered significant damage.

  • Global Warming Increased U.S. Crop Insurance Losses by $27 Billion in 27 Years

    Higher temperatures attributed to climate change caused payouts from the nation’s biggest farm support program to increase by $27 billion between 1991 and 2017, according to new estimates from Stanford researchers. Costs are likely to rise even further with the growing intensity and frequency of heat waves and other severe weather events.

  • Action Essential to Protect Water Security from Climate Impacts

    A new report says that urgent action is needed to protect global water security from the impacts of climate and climate change.

  • July: U.S. West Hit with Extreme Heat, Drought, Unrelenting Wildfires

    July was an exceptional month of triple threats in the western United States: record heat, drought and raging wildfires. Other parts of the country saw extreme rainfall. The average temperature last month across the contiguous U.S. was 75.5 degrees F (1.9 degrees above average).

  • Dire Outlook on Global Warming: IPCC

    The IPCC warns that in twenty years, the world will likely reach — and even surpass — the 1.5-degree Celsius warming threshold that scientists have predicted will lead to irreversible changes such as melting glaciers, rising sea levels, and devastating floods and droughts around the world.

  • For Forest Towns, 3 Wildfire Lessons as Dixie Fire Destroys Historic Greenville, California

    How can people prepare for a future that’s unlike anything their communities have ever experienced? The emergence of extreme fires in recent years and the resulting devastation shows that communities need better means to anticipate mounting dangers, and underscores how settlement patterns, land management and lifestyles will have to change to prevent even larger catastrophes. Our research team of landscape architects, ecologists, social scientists and computer scientists has been exploring and testing strategies to help.

  • Four Explanations for Why Europe Is Burning

    Barely halfway through summer, the area burned by wildfires raging through the Balkans, Italy, and the southeastern Mediterranean has already eclipsed yearly averages.

  • National Security Agencies Must Include Climate Risks and Their Analyses

    The Pentagon and other federal agencies were given a July deadline to draw up plans for potential climate risks, under an executive order by President Biden. Antonio Busalacchi and Sherri Goodman write that such plans are an essential first step, but the greater challenge for national security agencies is to continue to redirect their focus to changing climate conditions that pose a complex, two-pronged threat: social and political instability overseas and damage to U.S. infrastructure.

  • Administration Commits $3.46 Billion to Reduce Effects of Climate Change

    Communities across the country have been impacted by the effects of hurricanes, floods, wildfires, earthquakes, and other events. The increasing duration, intensity, and severity of such disasters—which are exacerbated by climate change as well as changes in population, land use, and weather patterns—are alarming and devastating. New funds made available by the government for hazard mitigation.

  • Warming to Affect Water Availability for Hydropower, Public Water Supply in Wales

    New research shows that as the temperature increases, water supplies in Wales dwindle, leading to shortages for both the hydropower industry and public water consumptions. As the temperature rises, more water will have to be released from reservoirs to satisfy consumer demands – but such releases will lower water levels in the reservoirs below the needs of hydropower generation.

  • “Less Than 1% Probability” that Increase in Earth’s Energy Imbalance Occurred Naturally

    The fundamental energy balance sheet for our planet is straightforward: Sunlight in, reflected and emitted energy out. If the Earth’s oceans and land surfaces send as much energy back up to space as the sun shines down on us, then our planet maintains equilibrium. But for decades the system has been out of balance, resulting in the growing number, intensity, lethality, and damage of extreme weather events. The reason: The increasing emission of greenhouse gases.
