• Devastating Hurricanes Could Be Up to Five Times More Likely in the Caribbean

    Global warming is dramatically increasing the risk of extreme hurricanes in the Caribbean, but meeting more ambitious climate change goals could up to halve the likelihood of such disasters in the region, according to new research.

  • Natural Disasters Must Be Unusual or Deadly to Prompt Local Climate Policy Change

    Natural disasters alone are not enough to motivate local communities to engage in climate change mitigation or adaptation, a new study found. Rather, policy change in response to extreme weather events appears to depend on a combination of factors, including fatalities, sustained media coverage, the unusualness of the event and the political makeup of the community.

  • Amateur Drone to Aid in Natural Disaster Damage Assessment

    It wasn’t long after Hurricane Laura hit the Gulf Coast Thursday that people began flying drones to record the damage and posting videos on social media. Those videos are a precious resource, say researchers at Carnegie Mellon University, who are working on ways to use them for rapid damage assessment.

  • Sea Level Rise Matches Worst-Case Scenario

    Ice sheets in Greenland and Antarctica whose melting rates are rapidly increasing have raised the global sea level by 1.8cm since the 1990s, and are matching worst-case climate warming scenarios. “The melting is overtaking the climate models we use to guide us, and we are in danger of being unprepared for the risks posed by sea level rise,” says one expert.

  • U.S. Flood Strategy Shifts to ‘Unavoidable’ Relocation of Entire Neighborhoods

    For years, even as seas rose and flooding worsened nationwide, policymakers stuck to the belief that relocating entire communities away from vulnerable areas was simply too extreme to consider — an attack on Americans’ love of home and private property as well as a costly use of taxpayer dollars. Christopher Flavelle writes that now, however, that is rapidly changing amid acceptance that rebuilding over and over after successive floods makes little sense. Using tax dollars to move whole communities out of flood zones is swiftly becoming policy, marking a new and more disruptive phase of climate change.

  • Better Typhoon Predictions

    Tropical cyclones, also known as typhoons, wreak havoc in Asia and the Pacific. The storms can be deadly—in 2013, Typhoon Haiyan, the strongest ever recorded, was responsible for 6,340 deaths—and cost billions in damages. Current forecast models can only predict these storms 10 days in advance, at most, and they cannot precisely predict how intense the storms will become. To rectify this, an international team of researchers has developed a model that analyzes nearly a quarter of Earth’s surface and atmosphere in order to better predict the conditions that birth typhoons, as well as the conditions that lead to more severe storms.

  • Warming May Force Some Favorite Produce Crops to Get a Move On

    Record drought and heat have some farmers worried about where and when crops can be grown in the future, even in California where unprecedented microclimate diversity creates ideal growing conditions for many of the most popular items in America’s grocery stores Warmer California temperatures by mid-century will be too hot for some crops, just right for others.

  • The World's Biggest Waves: How Climate Change Could Trigger Large Landslides and “Mega-Tsunamis”

    Natural hazards which are triggered, made more frequent, or exacerbated by climate change can’t be prevented, but damage to infrastructure and populations can be minimized. This can be achieved through scientific understanding of the physical processes, site-specific engineering risk analysis and coastal management of hazard-prone regions.

  • Warming Greenland Ice Sheet Passes Point of No Return

    Nearly forty years of satellite data from Greenland shows that glaciers on the island have shrunk so much that even if global warming were to stop today, the ice sheet would continue shrinking. The finding means that Greenland’s glaciers have passed a tipping point of sorts, where the snowfall that replenishes the ice sheet each year cannot keep up with the ice that is flowing into the ocean from glaciers.

  • Sea-Level Rise Linked to Higher Water Tables Along California Coast

    In the first comprehensive study of the link between rising sea levels and inland water tables along the California coast, researchers found an increased threat to populated areas already at risk from rising water tables, and the possibility of flooding in unexpected inland areas.

  • Resilience solutions for international power system planners

    When a power system fails, consequences can be catastrophic. At-risk communities may be left without access to lifesaving medical resources, while sanitation, manufacturing, and other critical services may be rendered powerless and unable to function. If a nation or region is geographically isolated or otherwise poorly equipped to respond, recovery time can take even longer.

  • Demographics Data Helps Predict N.Y. Flood Insurance Claims

    In flood-prone areas of the Hudson River valley in New York state, census areas with more white and affluent home owners tend to file a higher percentage of flood insurance claims than lower-income, minority residents, raising the issue of developing more nuanced, need-based federal flood insurance subsidies in these floodplains, according to a new study.

  • A Warming California Will See Reservoirs Overwhelmed by Floods

    By the 2070s, global warming will increase extreme rainfall and reduce snowfall in the Sierra Nevada, delivering a double whammy that will likely overwhelm California’s reservoirs and heighten the risk of flooding in much of the state.

  • Facing Climate Threats, Landmarks May Have to Adapt and “Transform”

    How much effort should be spent trying to keep Venice looking like Venice – even as it faces rising sea levels that threaten the city with more frequent extreme flooding? As climate change threatens cultural sites, preservationists and researchers are asking whether these iconic locations should be meticulously restored or should be allowed to adapt and “transform.”

  • Let’s Not Forget the Important Lessons the Coronavirus Taught Us about Supply Chains

    Resilience is priceless when you really need it. It turns out our economic systems are more fragile than we thought. As locations across the world implemented “shelter-in-place” orders in an effort to flatten the coronavirus contagion curve last spring, we got a real-time lesson in how intertwined our transportation and distribution systems are. It was staggering to see how efforts to curb the human toll of a pandemic rippled across every sector and created incalculable emotional and social impacts.
