    There lacks a method to measure the rapid changes of vehicle emissions. Here the authors proposed a big data approach ‘TrackATruck’, and their estimates using the new approach show that the heavy-duty trucks (HDT) emissions of primary cargo routes/terminals were underestimated by 2–10 times in proxy-based emission inventories.

    Here the authors develop a set of global, long-term, spatial projections of urban land expansion for understanding the planet’s potential urban futures. The global total amount of urban land increases by a factor of 1.8-5.9 over the 21st century, and the developed world experiences as much new urban development as the developing world.

    There lacks a spatially explicit mapping of global carbon footprint in China that considers both international and interprovincial trade. Here the authors map the carbon footprints of global regions in China and show the hotspots concentrated in key manufacturing hubs, including the Yangtze River Delta, Pearl River Delta, and North China Plain.

    Generally it is thought that confining clay layers provide protection to low-arsenic groundwaters against intrusion of shallower, high-arsenic groundwater bodies. Here, the authors show that impermeable clay layers can increase arsenic input to underlying groundwater systems due to reduction of iron oxides coupled to carbon oxidation.

    A primary element of modern wildfire management is to aggressively suppress small fires before they become large, but benefits can be offset by the fact that these practices promote older forests that are more ‘flammable’. Here the authors show that this downside puts numerous human communities at elevated risk of fires in boreal Canada.

    Countries are adopting ecological compensation policies aimed at achieving no net loss of biodiversity and ecosystem services. Here, Sonter and colleagues apply spatial simulation models to case studies in Australia, Brazil, Indonesia, and Mozambique to show that compensation alone is not sufficient to preserve biodiversity.

    Arctic plant growth is predominantly nitrogen limited, where the slow nitrogen turnover in the soil is commonly attributed to the cold arctic climate. Here the authors show that the arctic plant-soil nitrogen cycling is also constrained by the lack of larger detritivores like earthworms.

    Plastic pollution is an escalating problem and there is a need to predict the range of plastic sizes that an organism of interest could feasibly ingest. Here the authors use previously published data to develop an allometric equation for plastic size ingested as a function of animal body size, a relationship which could help predict risk of plastic introduction into food webs.

    The dominant emission sources of anthropogenic radionuclides come from either atmospheric nuclear weapons tests or the nuclear industry (i.e., reprocessing plants or reactor accidents). Here, the authors identify a new environmental isotope tracer ($$^{233}$$233U/$$^{236}$$236U) which can help distinguish emissions from nuclear weapons tests, and can also provide constraints on past weapon designs and fuel sources, for which many details remain classified or lost.

    Global soil carbon dynamics are regulated by the modification of soil organic matter (SOM) decomposition by plant carbon input (priming effect). Here, the authors collect soil data along a 2200 km grassland transect on the Tibetan Plateau and find that SOM stability is the major control on priming effect.
