• 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.

  • 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.

  • 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.

  • Water Efficiency Achievable Throughout U.S. without Decrease in Economic Activity

    A recent study showed that targeted efforts to increase water efficiency could save enough water annually to fill Lake Mead. It could happen without significantly compromising economic production, jobs or tax revenue.

  • 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.

  • EU Payments to Farmers Fail to Deliver on Competitiveness, Sustainability

    Over 40 billion euro is given annually to European agriculture as direct payments under the Common Agricultural Policy (CAP). Yet, the policy fails to deliver on what EU citizens are promised. The majority of payments are going to the regions causing the most environmental damage and the farmers in the least need of income support.

  • 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.

  • July 2020: Record Hot for Northern Hemisphere, 2nd Hottest for Planet

    July 2020 has tied for second-hottest July on record for the globe, according to NOAA’s National Centers for Environmental Information. What is more, the Northern Hemisphere saw its hottest July ever  — surpassing its previous record high set in 2019.

  • 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.”

  • Bay Area Coastal Flooding Triggers Region-Wide Commute Disruptions

    Researchers have modeled how coastal flooding will impact commutes in the Bay Area over the next twenty years. Regions with sparse road networks will have some of the worst commute delays, regardless of their distances from the coast.
