• Assessing the Environmental Impact of Nuclear Power Generation

    Nuclear power is considered a panacea for the environmental degradation caused by fossil fuels. However, its environmental impact and natural resource use need to be assessed. Researchers make a life cycle assessment of resource use in nuclear power generation from uranium.

  • Climate Changes Lead to Water Imbalance, Conflict in Tibetan Plateau

    Climate change is putting an enormous strain on global water resources, and according to researchers, the Tibetan Plateau is suffering from a water imbalance so extreme that it could lead to an increase in international conflicts.

  • Developing Novel Hybrid Reef-Mimicking Structures

    Despite previous efforts to implement storm mitigation solutions — including concrete breakwaters — damage due to storm surge and flooding continues to devastate coastal areas around the world. In response to these threats, DARPA has launched the Reefense program to develop self-healing, hybrid biological, and engineered reef-mimicking structures to protect civilian and DoD infrastructure, personnel by mitigating damage related to coastal flooding, erosion and storm surge.

  • Most Major U.S. Cities Underprepared for Rising Temperatures

    This month, Denver, Las Vegas and Phoenix all posted record high temperatures. And across the nation, Americans are ramping up for a scorching summer. Yet despite more frequent and intense heat waves on the horizon, cities are underprepared to deal with the challenge.

  • Declining Water Reserves in California May Cut Hydropower Use in Half This Summer

    As summer approaches, it’s clear that the heavy rains which pummeled California in late 2021 did little to shore up the state’s water reserves, and analysts are warning that the state’s hydroelectric supplies — a cheap source of clean power in California — are once again at risk.

  • Critical Global Water Questions

    Recent intense heatwaves in India and widespread U.S. droughts have highlighted the need for a global approach to tackling chronic water shortages. The problem is that most governments are not equipped to deal with these challenges of water scarcity, sanitation and climate dynamics.

  • Add-on Benefits of Natural Defenses Against Sea-Level Rise

    Researchers modeled how investing in environmental conservation and protection can help San Mateo County, California, adapt to rising seas. The findings provide incentives for policymakers to prioritize nature-based approaches when planning for sea-level rise.

  • Groundwater Depletion Causes California Farmland to Sink

    A new study simulates 65 years of land subsidence, or sinking, caused by groundwater depletion in California’s San Joaquin Valley. The results suggest significant sinking may continue for centuries after water levels stop declining but could slow within a few years if aquifers recover.

  • California Hydropower Could Be Cut in Half This Summer: Report

    A third year of drought spells less hydropower, more natural gas, and higher electricity prices. The U.S. Energy Information Administration, or EIA, reported last week that as reservoir levels dip far below their historic averages, electricity generation from California’s hydroelectric dams could be cut in half this summer.

  • Challenges to Tidal Flats Pose Risks to 41M Americans Living in Coastal Counties

    About 29 percent of the United States’ population live in coastline counties – more than 41 million are in Atlantic counties. This high population density poses a critical challenge to sustainable developments in coastal areas.

  • Hydropower’s Future Is Clouded by Droughts, Floods and Climate Change – It’s Also Essential to the U.S. Electric Grid

    The United States has over 2,100 operational hydroelectric dams, with locations in nearly every state. They play essential roles in their regional power grids. But most were built in the past century under a different climate than they face today. As global temperatures rise and the climate continues to change, competition for water will increase, and the way hydropower supply is managed within regions and across the power grid in the U.S. will have to evolve.

  • Diminishing Snowmelt to Make Colorado, Utah, Wyoming Resemble the Arid Southwest

    New research predicts that changes in mountain snowmelt will shift peak stream flows to much earlier in the year for the vast Colorado River Basin, altering reservoir management and irrigation across the entire region. As a result, upper basin in Colorado, Utah, and Wyoming may more closely resemble the arid Southwest.

  • Climate Change Could Spark the Next Pandemic

    As the Earth’s climate continues to warm, researchers predict wild animals will be forced to relocate their habitats — likely to regions with large human populations — dramatically increasing the risk of a viral jump to humans that could lead to the next pandemic.

  • Droughts Self-Propagate, Just Like Wildfires

    Unlike other weather extremes such as hurricanes or winter storms, droughts affect humans in most climatic zones around the world; from the arid steppes of the Sahel to the humid rainforests of Amazonia. Moreover, droughts are expected to intensify in many regions following global warming.

  • Scientists Identify the Most Extreme Heatwaves Ever Recorded Globally

    Heatwaves are one of the most devastating extreme weather events. The western North America heatwave was the deadliest weather event ever in Canada, resulting in hundreds of fatalities. The associated raging wildfires also led to extensive infrastructure damage and loss of crops.
