• A Simple Simulation Helps Coastal Towns Plan for Rising Sea Levels

    Climate change causes sea level rise and increasingly strong coastal storms. Knowing how water moves through coastal structures can yield important insights for residents and planners.

  • Natural Hazards Threaten 57% of U.S. Structures

    As a result of increasing temperatures and environmental changes, more than half of the structures in the contiguous United States are exposed to potentially devastating natural hazards—such as floods, tornadoes, hurricanes, and wildfires.

  • Role of Managed Retreat as a Climate Change Response

    Managed retreat—the climate adaptation response of moving people and property out of harm’s way— is becomig more appealing as one of several responses to sea-level rise. Researchers explore what it would take for managed retreat to be supportive of people and their priorities. The key is to consider retreat alongside other responses like coastal defenses, and not just as an option of last resort.

  • “Managed Retreat” Can Reinvent Cities While Protecting Lives When Climate Change Floods, Burns or Bakes the Land

    Record-breaking heat waves; megadroughts, drying fresh-water sources; hotter and more frequent wildfires; intensifying hurricanes — this is what climate change looks like, and communities need to be prepared. Sometimes small adaptations can help reduce the heat or minimize the damage. But when the risks get too high, one strategy that has to be considered is managed retreat – the purposeful movement of people, buildings and other infrastructure away from highly hazardous places.

  • Texas Must Address Groundwater Future: Study

    Long-term water security is essential for the future of Texas, and the state acutely needs a common law system that can balance world-scale agricultural activity, industrial development and urban growth while also protecting private property rights, according to new research.

  • Earlier Flood Forecasting Could Help Avoid Disaster in Japan

    In Japan, thousands of homes and businesses and hundreds of lives have been lost to typhoons. But now, researchers have revealed that a new flood forecasting system could provide earlier flood warnings, giving people more time to prepare or evacuate, and potentially saving lives.

  • New Building Standard Can Map Out Tornado Threat for the First Time

    Of the natural hazards in Mother Nature’s arsenal, tornadoes are some of the most vicious. But while other hazards are regularly considered in building designs, tornadoes have not been part of the equation for most structures in the United States, even in highly tornado-prone regions. Now, an upcoming edition of a critical building standard gives tornadoes some much needed attention.

  • Overseas Climate Change Could Devastate U.K.

    The effects of climate change overseas could have a potentially devastating impact on the economy here in the UK. The UK economy is particularly exposed to risks because of London’s prominent role at the center of the global insurance market. Climate change will lead to rising sea levels and wildfires, as well as an increase in the frequency of extreme weather events such as droughts, floods, and severe storms.

  • Puerto Rico is Prone to More Flooding Than the Island is Prepared to Handle

    Puerto Rico is not ready for another hurricane season, let alone the effects of climate change, according to a new study that shows the island’s outstanding capacity to produce record-breaking floods and trigger a large number of landslides.

  • Acceleration of Coastal Overtopping around the World

    The combination of sea level rise, tides, storm surge and waves has increased the overtopping of natural and artificial coastal protection by nearly 50 percent in the last two decades. By combining satellite data and digital models, the researchers have shown that coastal overtopping, and consequently the risk of flooding, is set to further accelerate over the 21st century, by up to 50-fold under a high emission global warming scenario, especially in the tropics. This increase is principally caused by a combination of sea level rise and ocean waves.

  • Coastal Cities of the Future

    It’s time to put all the options on the table when it comes to discussing climate change adaptation. Managed retreat — the purposeful movement of people, buildings and other assets from areas vulnerable to hazards — has often been considered a last resort. But experts say it can be a powerful tool for expanding the range of possible solutions to cope with rising sea levels, flooding and other climate change effects when used proactively or in combination with other measures.

  • Managed Retreat Conference

    The Columbia Climate School and its Earth Institute, will hold a virtual conference 22-25 June 20201 on the subject of managed retreat. conference will address a range of scientific, social, policy, and governance issues around managed retreat (also known as strategic realignment and planned relocation).

  • Drought and Record Heat in the West: The Climate Change Connection

    As intense drought and record heat make their way across the Western U.S., the deep and devastating impacts of this extreme weather are clear — electric utilities are asking consumers to ration power and water, farmers are scrambling to sell or save their produce, and officials are making plans to keep their communities safe and cool. All before true summer weather arrives. Research shows that these extreme events are expected to continue as our climate changes.

  • Exploring the Possible Risks, Benefits of Geoengineering

    Climate change is creating impacts that are widespread and severe — and in many cases irreversible — for individuals, communities, economies, and ecosystems around the world. 2020 was one of the three warmest years on record, bringing with it a number of costly climate disasters, including the worst wildfire season ever recorded in the Western U.S., historic flooding in China and other parts of Asia, and severe droughts in South America. One of the approaches to avoid the most serious, possibly catastrophic impacts, of climate change is solar geoengineering.

  • Early Wildfires Detection Systems Successfully Tested

    The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) successfully tested four prototype technologies for early detection of wildfires in California this week. The test was the second phase of S&T’s Wildland Urban Interface (WUI) wildfire sensor technology program.
