Global predictions of primary soil salinization under changing climate in the 21st century

This study uses machine learning to predict changes in primary soil salinity in drylands globally up to the year 2100 under different climate change scenarios. The models predict increased salinity risk in parts of South America, Australia, Mexico, and South Africa, while some regions in North America, the Horn of Africa, and Central Asia may experience a decrease.

Version 3 of the Global Aridity Index and Potential Evapotranspiration Database

This paper introduces version 3 of the Global Aridity Index and Potential Evapotranspiration Database (Global-AI_PET_v3). It offers improved estimates of potential evapotranspiration (PET) and aridity index (AI) globally at a 30 arc-second resolution, based on the FAO-56 Penman-Monteith equation and WorldClim 2.1 climate data. The updated dataset shows higher correlation with weather station data compared to previous versions and provides a valuable tool for various scientific applications.

SoilGrids 2.0: producing soil information for the globe with quantified spatial uncertainty

SoilGrids 2.0 uses machine learning and a large global dataset of soil observations with environmental covariates to produce updated maps of soil properties like pH, organic carbon content, and texture. The maps include estimates of uncertainty and show improved performance compared to previous versions, but highlight the need for more soil data, particularly at high latitudes.

Coastal flooding will disproportionately impact people on river deltas

The study found that 339 million people lived on river deltas in 2017, with 89% residing in tropical cyclone zones. 31 million delta inhabitants are exposed to 100-year flood risk, 28 million in developing economies, and 25 million on deltas that can’t naturally mitigate flooding.

Sea-level rise exponentially increases coastal flood frequency

The study finds that the odds of exceeding critical water level thresholds increase exponentially with sea-level rise, doubling approximately every 5 years. By 2100, the present-day 50-year extreme water level is projected to be exceeded almost daily during high tides for 90% of the U.S. coast, highlighting the urgent need for adaptation measures.

Hyperpycnal (over density) flows and deposits

Hyperpycnal flows, formed when dense river discharges plunge into lakes or oceans, create unique deposits called hyperpycnites. These deposits differ depending on the flow type (pebbly, sandy, muddy), with variations arising from factors like flow duration, sediment concentration, and basin salinity. Lofting, caused by freshwater buoyancy, is unique to marine/saline settings and creates distinctive rhythmites in hyperpycnites.
