  • 'Green'-feed: Industrial microbes could feed cattle, pigs, chicken
    on June 20, 2018 at 1:48 pm

    Today, producing feed for pigs, cattle and chicken causes immense impacts for the climate and the environment. In the future, animal feed production is likely to be shifted from croplands to large-scale industrial facilities as it could bring both financial and environmental benefits. Replacing 2 percent feed with protein-rich microbes could decrease agricultural greenhouse gas emissions, global cropland area and nitrogen losses by over 5 percent. […]

  • Machine learning may be a game-changer for climate prediction
    on June 19, 2018 at 9:35 pm

    New research demonstrates that machine-learning techniques can be used to accurately represent clouds and their atmospheric heating and moistening, and better represent clouds in coarse resolution climate models, with the potential to narrow the range of climate prediction. This could be a major advance in accurate predictions of global warming in response to increased greenhouse gas concentrations that are essential for policy-makers (e.g. the Paris climate agreement). […]

  • Political leaning influences city water policies as strongly as climate
    on June 19, 2018 at 9:29 pm

    Researchers examined city water policies over the course of four years to create a database of water conservation policies. They also developed an associated index of the number of different categories of policies each city adopted and gathered data on the climate, water sources, population, economy and political leanings of each city and its surrounding metropolitan statistical area -- as reflected in the 2008 and 2012 presidential elections. […]

  • Ocean's heat cycle shows that atmospheric carbon may be headed elsewhere
    on June 19, 2018 at 5:28 pm

    A new study examined the global carbon cycle and suggests that scientists may have misgauged how carbon is distributed around the world, particularly between the northern and southern hemispheres.

  • Local interventions boost coral's resilience to bleaching
    on June 19, 2018 at 2:24 am

    Local conservation actions can significantly boost coral's resilience to, and recovery from, climate-induced thermal bleaching by reducing other energy-sapping stresses the coral faces, a new study finds. Scientists found they could reduce the extent of bleaching by half if they removed or reduced populations of coral-eating snails from affected reefs. The coral's recovery from bleaching was also enhanced. […]

  • Better be safe than sorry: Economic optimization risks tipping of Earth system elements
    on June 15, 2018 at 7:44 pm

    Optimizing economic welfare without constraints might put human well-being at risk, a new climate study argues. While being successful in bringing down costs of greenhouse gas reductions for instance, the concept of profit maximization alone does not suffice to avoid the tipping of critical elements in the Earth system which could lead to dramatic changes of our lifelihood. The scientists use mathematical experiments to compare economic optimization to the governance concepts of sustainability and the more recent approach of a safe operating space for humanity. All of these turn out to have their benefits and deficits, yet the profit-maximizing approach shows the greatest likelihood of producing outcomes that harm people or the environment. […]

  • Land-based portion of massive East Antarctic ice sheet retreated little during past eight million...
    on June 15, 2018 at 7:44 pm

  • What saved the West Antarctic Ice Sheet 10,000 years ago will not save it today
    on June 14, 2018 at 2:12 pm

    The retreat of the West Antarctic ice masses after the last Ice Age was reversed surprisingly about 10,000 years ago, scientists found. The reason for the rebound is that, relieved from the weight of the retreating ice, the Earth crust lifted. This made the ice re-advance towards the ocean. Unfortunately, this mechanism is much to slow to prevent dangerous sea-level rise caused by West Antarctica's ice-loss in the present and near future. […]

  • Ocean waves following sea ice loss trigger Antarctic ice shelf collapse
    on June 14, 2018 at 1:52 pm
