• The Historic Claims That Put a Few California Farming Families First in Line for Colorado River Water

    Twenty families in the Imperial Valley received a whopping 386.5 billion gallons of the river’s water last year — more than three Western states. Century-old water rights guarantee that supply.

  • Reforms Needed to Expand Prescribed Burns

    Prescribed fire, which mimics natural fire regimes, can help improve forest health and reduce the likelihood of catastrophic wildfire. But this management tool is underused in the fire-prone U.S. West and Baja California, Mexico, due to several barriers. Study highlights four strategies to overcome barriers to prescribed fire in the West.

  • First 10 Months of 2023 See Record 25 Billion-Dollar Disasters

    NOAA confirmed another billion-dollar disaster in October, bringing the total to a record 25 disasters in the first 10 months — the largest number of disasters for any year since NOAA has kept track of these types of events. The Mississippi River’s water level dropped to historic lows along parts of the river.

  • Scientists Map Loss of Groundwater Storage Around the World

    Global water resources are stretched by climate change and human population growth, and farms and cities are increasingly turning to groundwater to fill their needs. Unfortunately, the pumping of groundwater can cause the ground surface above to sink. A new study maps, for the first time, the permanent loss of aquifer storage capacity occurring globally.

  • Climate Change Is a National Security Risk

    Climate change is affecting practically everything on Earth, from natural systems to human endeavors. National security is no exception. The U.S. Defense Department recognizes that climate change is a “threat multiplier” as it exacerbates existing environmental stresses and security risks.

  • Biden’s $8 Billion Quest to Solve America’s Groundwater Crisis

    A looming depletion of groundwater across the U.S. has drawn nationwide attention in recent years, as local officials in states from Kansas to Arizona struggle to manage dwindling water resources even as homes and farms get thirstier. With little fanfare, the administration is using infrastructure funding to revive dormant plans for pipelines and reservoirs in rural areas across the U.S. West.

  • Floridians Believe in Climate Change, Want Government Action

    The latest edition of the Florida Climate Resilience Survey found that 90 percent of Floridians believe climate change is happening, a higher figure than in the nation as a whole: a recent Yale University survey found that 74 percent of Americans as a whole think climate change is happening.

  • Arizona Is Evicting a Saudi Alfalfa Farm, but the Thirsty Crop Isn’t Going Anywhere

    As Arizona struggles to adapt to a water shortage that has dried out farms and scuttled development plans, one company has emerged as a central villain. The agricultural company Fondomonte, which is owned by a Saudi Arabian conglomerate, has attracted criticism over the past several years for sucking up the state’s groundwater to grow alfalfa and then exporting that alfalfa to feed cows overseas. Now Arizona has cancelled one of the company’s leases and says it will not renew the others, but the decision will do little to solve a water shortage largely driven by irrigated agriculture.

  • Experts Warn of Risk of Civil Unrest in U.K. Due to Food Shortages

    Food shortages—especially a shortage of popular carbohydrates such as wheat, bread, pasta, and cereal — caused by extreme weather could lead to civil unrest in the U.K., according to a new study, which has surveyed some of the country’s leading food experts.

  • Are We Running Out of Water? Water Security Threatened by Droughts and Heatwaves Worldwide

    Increased demand for water due to global population growth, coupled with the increasing frequency of extreme weather events, endangers our water security. Nonetheless, little is known about the relationship of water use by sectors and the occurrence of drought-heatwave events, particularly at the large scale.

  • Climate Intervention Technologies May Create Winners and Losers in World Food Supply

    A technology being studied to curb climate change – one that could be put in place in one or two decades if work on the technology began now – would affect food productivity in parts of planet Earth in dramatically different ways, benefiting some areas, and adversely affecting others.

  • What’s Causing the Panama Canal Logjam

    Low water levels have, the result of prolonged drought conditions, led to a traffic jam at one of the world’s busiest maritime passages. The Panama Canal Authority has capped the number of ships that cross the canal each day, and has restricted their maximum weight and draft, or how deep below the waterline a ship sits. The bottleneck demonstrates how accelerating climate change is threatening global supply chains.

  • What Fuels Wildfires in Sierra Nevada Mountains

    Wildfires in California, exacerbated by human-driven climate change, are getting more severe. To better manage them, there’s a growing need to know exactly what fuels the blazes after they ignite. One of the chief fuels of wildfires in California’s Sierra Nevada mountains is the decades-old remains of large trees.

  • How Do We Dismantle Offshore Oil Structures Without Making the Public Pay?

    More than 12,000 offshore oil and gas installations straddle the globe, and industry analysts anticipate annual offshore oil and gas investments to reach $173 billion by 2024. A number of oil companies are expected to significantly expand their offshore drilling activities in the coming years. At the same time, many jurisdictions face a growing need to dismantle offshore infrastructure, whether because it is aging, the resources are depleted, or mandated net-zero strategies require some installations to be decommissioned earlier than expected.

  • ‘A Silent Killer’: How Saltwater Intrusion is Overtaking Coastal Farmland in the U.S.

    As hurricanes get stronger, storm surges are bringing saltwater to farmland—and leaving salt there once waters evaporate. And as sea level increases due to climate change, the difference between ocean water levels and soil elevation is decreasing, making post-storm water runoff more difficult. With enough flooding, the soil on farms could become so salinized that crops can no longer be grown on that land. The salt eventually makes contact with freshwater aquifers, thus salinizing them.
