• 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.

  • World's Largest Outdoor Earthquake Simulator Undergoes Major Upgrade

    A major upgrade to the world’s largest outdoor earthquake simulator reached a milestone mid-April when the facility’s floor—all 300,000 lbs of it—was put back into place. When completed this fall, the simulator will have the ability to reproduce multi-dimensional earthquake motions with unprecedented accuracy to make structures and their residents safer during strong shakes.

  • Teaching Drones to Hear Screams from Catastrophe Victims

    In a disaster, time is of the essence when searching for potential victims who may be difficult to find. Unmanned aerial vehicles make the perfect platform for state-of-the-art technology allowing emergency crews to find those in need and provide situational awareness over a large area.

  • Analysis: The Texas Electric Grid and the Improvements that Didn’t Come

    After the deadly and expensive electrical outages during a winter freeze in February, Texas lawmakers passed major bills aiming to make such disasters less likely in the future. But there’s still a lot to do.

  • 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.

  • 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.”
