• Technologies to Manage Climate Change Already Exist – but U.K. Needs to Scale Up Efforts Urgently

    In the U.K., climate change is being tackled by taking baby steps. Andreas Busch writes that this is unfortunate, because “The world already has effective engineering solutions to manage climate change and to limit global temperatures from rising above 1.5°C – a target set by the Intergovernmental Panel on Climate Change (IPCC). But there is a desperate lack of conviction from politicians and society to address the climate emergency.”

  • The Sea Wanted to Take This California Lighthouse. Now, It’s Part of a Conflict Between a Town and Two Tribes

    For decades, the Trinidad Memorial Lighthouse stood like atop the coastal bluff overlooking the rocky outcrops of Trinidad Bay in northern California. But then, climate change began to take its toll: “the ground began to crumble. Rain moved the earth. The bluff cracked, a sidewalk warped, and thus ended the charmed life of the Trinidad Memorial Lighthouse, which suddenly threatened to slide into the Pacific,” Hailey Branson-Potts writes.

  • Policy Decisions' Effect on Migration from Sea Level Rise

    A new modeling approach can help researchers, policymakers and the public better understand how policy decisions will influence human migration as sea levels rise around the globe. “Sea level rise is going to reorganize the human population around the globe,” says one researcher.

  • Greenhouse Gas Concentrations in Atmosphere Reach Yet Another High

    Levels of heat-trapping greenhouse gases in the atmosphere have reached another new record high, according to the World Meteorological Organization. This continuing long-term trend means that future generations will be confronted with increasingly severe impacts of climate change, including rising temperatures, more extreme weather, water stress, sea level rise and disruption to marine and land ecosystems.

  • Conservatives More Likely to Support Climate Policy If They Experience Weather-Related Harm

    People who identify as politically conservative are more like to support climate change mitigation policies if they have reported experiencing personal harm from an extreme weather event such as a wildfire, flood or tornado, a new study indicates.

  • Studying Large Storm to Help Lessen Their Impact on Coasts

    When cyclones or other massive oceanic storms make landfall, their giant waves batter coastlines and sometimes cause widespread damage. Researchers have analyzed months of data of large nearshore waves to provide new insights that could help improve the designs of a variety of coastal structures from seaports to seawalls to better withstand destructive waves.

  • Florida’s Building Code Doesn’t Take Sea Rise into Account. That Could Change This Year.

    The last time the Florida building code changed, in 2016, it required any new construction along the coast to elevate buildings by one foot. Three years later, this does not look to be enough. Experts call for going up yet another foot. Alex Harris notes that elevating the base of homes is a clear sign that political debates over climate change notwithstanding, “the people who plan and build in coastal Florida consider the threat of sea rise very real.”

  • Rising Seas Threaten Low-Lying Coastal Cities, 10 percent of World Population

    A new report from the Coalition for Urban Transitions finds that, because sea level rise exacerbates flooding and storm surge, it is a critical threat to urban coastal areas. More than 10 percent of the world’s population now resides in urban centers or quasi-urban clusters situated at less than 10 meters above sea level.

  • Hurricanes in U.S. Have Become Bigger, Stronger, More Destructive

    A new study shows that hurricanes have become more destructive since 1900, and the worst of them are more than three times as frequent now than 100 years ago. A new way of calculating the destruction, compensating for the societal change in wealth, unequivocally shows a climatic increase in the frequency of the most destructive hurricanes that routinely raise havoc on the North American south- and east coast.

  • How Scientists Got Climate Change So Wrong

    Few thought it would arrive so quickly. Now we’re facing consequences once viewed as fringe scenarios. Had a scientist in the early 1990s suggested that within 25 years a single heat wave would measurably raise sea levels, at an estimated two one-hundredths of an inch, bake the Arctic and produce Sahara-like temperatures in Paris and Berlin, the prediction would have been dismissed as alarmist. But many worst-case scenarios from that time are now realities.

  • Plants Demand More Water as Climate Warms, Leaving Less for People

    As climate changes, plants in North America, much of Eurasia, and parts of central and South America will consume more water than they do now, leading to less water for people, according to a new study. The research suggests a drier future despite anticipated increases in precipitation in populous parts of the United States and Europe that already face water stresses.

  • World Scientists Declare Climate Emergency

    A global coalition of scientists says “untold human suffering” is unavoidable without deep and lasting shifts in human activities that contribute to greenhouse gas emissions and other factors related to climate change. In a paper published in BioScience, the authors, along with more than 11,000 scientist signatories from 153 countries, declare a climate emergency, present graphics showing trends as vital signs against which to measure progress, and provide a set of effective mitigating actions.

  • California Wildfires Signal the Arrival of a Planetary Fire Age

    Another autumn, more fires, more refugees and incinerated homes. For California, flames have become the colors of fall. Stephen Pyne writes that free-burning fire is the proximate provocation for the havoc, since its ember storms are engulfing landscapes. But in the hands of humans, combustion is also the deeper cause. Modern societies are burning lithic landscapes - once-living biomass now fossilized into coal, gas and oil - which is aggravating the burning of living landscapes. “Add up all the effects, direct and indirect – the areas burning, the areas needing to be burned, the off-site impacts with damaged watersheds and airsheds, the unraveling of biotas, the pervasive power of climate change, rising sea levels, a mass extinction, the disruption of human life and habitats – and you have a pyrogeography that looks eerily like an ice age for fire,” he writes. “You have a Pyrocene. The contours of such an epoch are already becoming visible through the smoke. If you doubt it, just ask California.”

  • Techno-Fix Futures Will Only Accelerate Climate Chaos – Don’t Believe the Hype

    Thanks to the efforts of climate activists, the climate and ecological emergency has never been more prominent. But acknowledging the problem is just a starting point. Now this momentum must be harnessed to dramatically reduce greenhouse gas emissions and reverse habitat destruction.

  • Should New York Build a Storm Surge Barrier?

    It’s been seven years since Superstorm Sandy brought the city that never sleeps to a grinding halt. The Superstorm Sandy anniversary also marks seven years since New York started talking about building storm surge barriers to protect itself from future storms. At a recent event hosted by Columbia University, experts discussed a study that is evaluating the feasibility of building storm surge barriers around New York and New Jersey. The panelists also debated whether such a measure is a good idea.
