• 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.

  • 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.

  • 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.

  • Difficult Tradeoffs: Climate Change and Dwindling Water Resources

    While a drought grips the southwestern United States and water supplies dwindle, decision-makers face increasingly difficult decisions about who, or what, gets water. Researchers have developed a model — the Framework for Assessment of Complex Environmental Tradeoffs (FACET) — designed to navigate and rigorously evaluate competing environmental, economic, and social impacts.

  • Increasing Pace, Intensity of Climate Hazards to Compound Security Threats: Report

    The other day the Expert Group of the International Military Council on Climate and Security (IMCCS) released its second annual World Climate and Security Report, which warns of the compound security threats posed by the convergence of climate change with other global risks, such as COVID-19.

  • How Does Climate Change Drive Migration, and What Can Be Done about It?

    April saw a 20-year high in the number of people stopped at the U.S./Mexico border, and President Joe Biden recently raised the cap on annual refugee admissions. Stanford researchers discuss how climate change’s effect on migration will change, how we can prepare for the impacts and what kind of policies could help alleviate the issue.

  • Climate Change Increases Extreme Rainfall and the Chance of Floods

    Climate experts warn that, without urgent action, climate change will continue to cause an increase in the intensity of extreme rainfall that can lead to severe flooding.

  • A 20-Foot Sea Wall? Miami Faces the Hard Choices of Climate Change.

    In Miami, the U.S. metropolitan area that is perhaps most exposed to sea-level rise, the problem is not climate change denialism. Patricia Mazzei writes that “the trouble is that the magnitude of the interconnected obstacles the region faces can feel overwhelming, and none of the possible solutions are cheap, easy or pretty.”

  • Retreat from Rising Seas

    As climate change causes seas to rise, coastal communities around the world face a difficult dilemma: Should they fight to keep their homes and communities above water, or accept that moving inland may be the best option?
