  • New climate risk classification created to account for potential 'existential' threats
    on September 15, 2017 at 1:06 am

    A new study evaluating models of future climate scenarios has led to the creation of the new risk categories 'catastrophic' and 'unknown' to characterize the range of threats posed by rapid global warming. Researchers propose that unknown risks imply existential threats to the survival of humanity. […]

  • Historic legacies affect climate change survival in Caribbean
    on September 12, 2017 at 5:48 pm

    Discussion of climate change has failed to pay enough attention to the social, political and historic factors which increase the vulnerability of Caribbean societies, and calls for a new approach focused on understanding and addressing these historic inequalities. […]

  • Study quantifies potential for water reuse in permian basin oil production
    on September 6, 2017 at 9:01 pm

    Hydraulic fracturing has once again made the Permian Basin one of the richest oil fields in the world. But the improved reserves come with some serious water management issues. Drilling for oil uses water upfront, and brings up large volumes of water that need to be managed. The study found that recycling the water produced during operations at other hydraulic fracturing sites could help reduce potential problems associated with the technology. […]

  • Jordan faces likelihood of much more frequent long and severe droughts
    on August 31, 2017 at 12:21 am

    on August 24, 2017 at 4:14 pm

    A team of researchers spent seven weeks in Antarctica collecting and studying 2,000-pound samples of glacial ice cores that date back nearly 12,000 years. The ancient air trapped within the ice revealed surprising new data about methane that may help inform today's policymakers as they consider ways to reduce global warming. […]

  • How 139 countries could be powered by 100 percent wind, water, and solar energy by 2050
    on August 23, 2017 at 4:13 pm

    The latest roadmap to a 100 percent renewable energy future outlines infrastructure changes that 139 countries can make to be entirely powered by wind, water, and sunlight by 2050 after electrification of all energy sectors. Such a transition could mean less worldwide energy consumption due to the efficiency of clean, renewable electricity; and a net increase of over 24 million long-term jobs. […]

  • Cause of Atlantic coastline's sea level rise hot spots now revealed
    on August 9, 2017 at 6:01 pm

    Seas rose in the southeastern US between 2011 and 2015 by more than six times the global average sea level rise that is already happening due to human-induced global warming, new research shows. The combined effects of El Niño (ENSO) and the North Atlantic Oscillation (NAO), both of which are naturally occurring climate processes, drove this recent sea level rise hot spot, according to the study. […]

    on July 27, 2017 at 2:29 pm

    A team of researchers has recently completed a global study on the trade-offs between the benefits provided by tropical forests and its conversion for agricultural use. The team examined deforestation activities of more than 50 countries in the tropics between 2000 to 2012, and identified regions where deforestation is most and least beneficial. […]

  • Climate change poses threat to European electricity production
    on July 25, 2017 at 1:01 pm

    The vulnerability of the European electricity sector to changes in water resources is set to worsen by 2030 as a consequence of climate change, conclude researchers. […]

  • Allowable 'carbon budget' most likely overestimated
    on July 24, 2017 at 3:41 pm

    While most climate scientists, including the Intergovernmental Panel on Climate Change, implicitly define 'pre-industrial' to be in the late 1800s, a true non-industrially influenced baseline is probably further in the past, according to an international team of researchers who are concerned because it affects the available carbon budget for meeting the 2 degrees Celsius (3.6 degrees Fahrenheit) warming limit agreed to in the Paris Conference of 2015. […]

  • Removing CO2 from the air required to safeguard children's future
    on July 18, 2017 at 3:37 pm

    Reducing greenhouse-gas emissions is not enough to limit global warming to a level that wouldn't risk young people's future, according to a new study by scientists who say we need negative emissions. Measures such as reforestation could accomplish much of the needed CO2 removal from the atmosphere, but continued high fossil fuel emissions would demand expensive technological solutions to extract CO2 and prevent dangerous warming. […]

  • Global hotspots for potential water conflict identified
    on July 17, 2017 at 8:00 pm

    More than 1,400 new dams or water diversion projects are planned or already under construction, fueling the potential for increased water conflict between some countries. […]

  • More children living in high-poverty neighborhoods following Great Recession
    on July 17, 2017 at 7:08 pm

    More children are living in high-poverty neighborhoods following the Great Recession -- a troubling shift because children in these neighborhoods are a year behind academically. […]

  • Ecological underpinnings of rural poverty
    on July 14, 2017 at 6:04 pm

  • Climate change to deplete some US water basins used for irrigation
    on July 12, 2017 at 3:04 pm

    Certain hotspots in the country will experience severe reductions in crop yields by 2050, due to climate change's impact on irrigation, a new study by climate scientists, economists, and agriculture experts finds. […]

  • Does the European public understand the impacts of climate change on the ocean?
    on July 11, 2017 at 12:55 pm

    Although many are relatively well informed, an alarming number remain either uninformed or misinformed when it comes to the impacts of climate change on the ocean, a new in-depth study of the European public's awareness shows. Many believe that Arctic sea-ice is already completely lost during the summer and that sea temperatures have already risen by more than 2°C. Climate science needs to be effectively communicated to the public so that citizens demand climate action. […]

  • Cellulosic biofuels can benefit the environment if managed correctly
    on June 29, 2017 at 6:28 pm

    Could cellulosic biofuels -- or liquid energy derived from grasses and wood -- become a green fuel of the future, providing an environmentally sustainable way of meeting energy needs? In a new article, researchers say yes, but with a few important caveats. […]

  • Regulating the indirect land use carbon emissions imposes high hidden costs on fuel
    on June 27, 2017 at 2:54 pm

    Biofuel policies like the Low-Carbon Fuel Standard in California are trying to minimize the indirect land use change related emissions by accounting for the indirect land use change factor as part of the carbon emissions per gallon of biofuels. A new study examines the costs and benefits of using this approach at a national level. […]

  • Rising seas could result in 2 billion refugees by 2100
    on June 26, 2017 at 2:57 pm

    In the year 2100, 2 billion people -- about one-fifth of the world's population -- could become climate change refugees due to rising ocean levels. Those who once lived on coastlines will face displacement and resettlement bottlenecks as they seek habitable places inland, according to new research. […]

  • Mathematical confirmation: Rewiring financial networks reduces systemic risk
    on June 22, 2017 at 2:39 pm
