  • 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. […]

  • 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

  • Climate change label leads to climate science acceptance
    on June 21, 2017 at 2:32 pm

  • Corn better used as food than biofuel, study finds
    on June 20, 2017 at 6:29 pm

    Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better utilized as food or as a biofuel has persisted since ethanol came into use. For the first time, researchers have quantified and compared these issues in terms of economics of the entire production system to determine if the benefits of biofuel corn outweigh the costs. […]
