Soil salinization has become one of the major environmental and socioeconomic issues globally this is expected to be exacerbated further with projected climatic change. Determining how climate change influences dynamics naturally-occurring soil scarcely been addressed due highly complex processes influencing salinization. This paper sets out address long-standing challenge by developing data-driven models capable predicting primary (naturally-occurring) salinity its variations in world's drylands up year 2100 under changing climate. Analysis future predictions made here identifies dryland areas South America, southern western Australia, Mexico, southwest United States, Africa as hotspots. Conversely, we project a decrease northwest Horn Africa, Eastern Europe, Turkmenistan, west Kazakhstan response over same period. Excess salt accumulation root zone causes health, biodiversity food security. Authors used machine learning algorithms predict global scale 21st century.

Soil organisms represent the most biologically diverse community on land and govern turnover of largest organic matter pool in terrestrial biosphere. The highly complex nature these communities at local scales has traditionally obscured efforts to identify unifying patterns global soil biodiversity biogeochemistry. As a result, environmental covariates have generally been used as proxy variation activity biogeochemical models. Yet over past decade, broad-scale studies begun see this heterogeneity biomass, diversity, composition certain groups across globe. These provide new insights into fundamental distribution dynamics land.

The Paris Agreement's goal of limiting the increase in global temperature to 1.5° or 2°C above preindustrial levels requires rapid reductions greenhouse gas emissions. Although reducing emissions from fossil fuels is essential for meeting this goal, other sources may also preclude its attainment. We show that even if fuel were immediately halted, current trends food systems would prevent achievement 1.5°C target and, by end century, threaten target. Meeting and ambitious changes as well all nonfood sectors. could be achieved with less-ambitious systems, but only are eliminated soon.

Abstract. We present a new data set of attributes for 671 catchments in the contiguous United States (CONUS) minimally impacted by human activities. This complements daily time series meteorological forcing and streamflow provided Newman et al. (2015b). To produce this extension, we synthesized diverse complementary sets to describe six main classes at catchment scale: topography, climate, streamflow, land cover, soil, geology. The spatial variations among basins over CONUS are discussed compared using maps. large number catchments, combined with diversity extracted, makes well suited large-sample studies comparative hydrology. In comparison similar Model Parameter Estimation Experiment (MOPEX) set, relies on more recent data, it covers wider range attributes, its evenly distributed across CONUS. study also involves assessments limitations source used compute as detailed descriptions how were computed. hydrometeorological (2015b, https://doi.org/10.5065/D6MW2F4D) together introduced paper (https://doi.org/10.5065/D6G73C3Q) constitute freely available CAMELS which stands Catchment Attributes MEteorology Large-sample Studies.

Significance Over many millennia, northern peatlands have accumulated large amounts of carbon and nitrogen, thus cooling the global climate. shorter timescales, peatland disturbances can trigger losses peat release greenhouses gases. Despite their importance to climate, remain poorly mapped, vulnerability permafrost warming is uncertain. This study compiles over 7,000 field observations present a data-driven map nitrogen stocks. We use these maps model impact thaw on find that will likely shift greenhouse gas balance peatlands. At present, cool but anthropogenic them into net source warming.
