    An intensity−duration−frequency model linking food shock risk to supply chain diversity in the USA finds that boosting a city’s food supply chain diversity increases the resistance of a city to food shocks of mild to moderate severity.

    The capacity to create an equitable and sustainable ‘blue economy’ from ocean resources will be determined by addressing social conditions, governance and infrastructure, not just resource availability, as shown by a fuzzy logic model incorporating multidisciplinary criteria.

    Analysis of forest-management studies finds that forest removal is more likely to increase streamflow in areas with greater water storage between the surface and bedrock, and that forest planting is more likely to decrease streamflow in drier climates.

    Climate has affected organized armed conflict within countries, and intensifying climate change is estimated to increase future risks of conflict, although other drivers are substantially more influential and the mechanisms of climate–conflict linkages remain uncertain.

    A global model finds that the environmental impacts of the food system could increase by 60–90% by 2050, and that dietary changes, improvements in technologies and management, and reductions in food loss and waste will all be needed to mitigate these impacts.

    Population-weighted analysis of US weather conditions shows that the nation’s weather has generally become more pleasant since 1974, possibly explaining the lack of broad public support for action on climate change; projections of future US weather indicate that conditions will probably worsen.
