Droughts of the future are likely to be more frequent, severe, and longer lasting than they have been in recent decades, but drought risks will lower if greenhouse gas emissions cut aggressively. This review presents a synopsis tools required for understanding statistics, physics, dynamics its causes historical context. Although these applied most extensively United States, Europe, Amazon region, not as widely used other drought-prone regions throughout rest world, presenting opportunities research. Water resource managers, early career scientists, veteran researchers see improve our drought.

Abstract The current and projected anthropogenic global warming the attendant increase in severity extent of soil degradation may exacerbate intensity duration drought occurrence agroecosystems. Restoration organic matter (SOM) content degraded/depleted soils can water retention (SWR) more at field capacity (FC) than that permanent wilting point (PWP), thus plant available (PAWC). magnitude PAWC depend on texture initial SOM content. Thus, restoration make them as well agroecosystems climate‐resilient. Management practices which enhance health by restoring include conservation agriculture, cover cropping, residue mulching, complex farming systems involving integration crops with trees livestock. Such technologies must be fine‐tuned under site‐specific conditions. Additional research is needed to establish cause‐effect relationship between ameliorative effect drought‐resilience for diverse cropping systems.

Abstract This review examines the role of atmospheric evaporative demand (AED) in drought. AED is a complex concept and here we discuss possible definitions, subsequent metrics to measure estimate AED, different physical drivers that control it. The influence on meteorological, environmental/agricultural hydrological droughts discussed, stressing important spatial differences related climatological conditions. Likewise, drought has implications regarding how consider their attempts quantify severity. Throughout article, assess literature findings with respect to: (a) recent trends future projections; (b) several uncertainties data availability; (c) sensitivity current AED; (d) roles both radiative physiological effects increasing CO 2 concentrations may play as progress into future. All these issues preclude identifying simple effect Rather it calls for evaluations impacts under climate scenarios, considering feedbacks governing system. article categorized under: Paleoclimates Current Trends > Earth System Behavior

Abstract Sahel rainfall is dynamically linked to the global Hadley cell and regional monsoon circulation. It therefore susceptible forcings from remote oceans land alike. Warming of enhances stability tropical atmosphere weakens deep ascent in Sahara nearby changes structure position shallow circulation allows more intense convective systems that determine seasonal rain accumulation. These processes can explain observed interannual multidecadal variability. Sea surface temperature anomalies were dominant forcing drought 1970s 1980s. In most recent decades, amounts have partially recovered, but rainy season characteristics changed: intermittent wetting concentrated late away west coast. Similar subseasonal subregional differences trends characterize simulated response increased greenhouse gases, suggesting an anthropogenic influence. While uncertainty future projections remains, confidence them encouraged by recognition mean depends on large‐scale drivers atmospheric circulations are well resolved current climate models. Nevertheless, observational modeling efforts needed provide refined changes, expanding beyond total accumulation metrics intraseasonal risk extreme events, coordination between scientists stakeholders generate relevant information useful even under uncertainty.

Abstract Terrestrial ecosystems are essential for food and water security CO 2 uptake. Ecosystem function is dependent on the availability of soil moisture, yet it unclear how climate change will alter moisture limitation vegetation. Here we use an ecosystem index that distinguishes energy limitations in Earth system model simulations to show a widespread regime shift from between 1980 2100. This found both space time. While this mainly related reduction energy-limited regions associated with increasing incoming shortwave radiation, largest towards where radiation increases accompanied by decreases. We therefore demonstrate stronger than implied individual trends terrestrial evaporation, important implications future services.

Drought is one of the most difficult natural hazards to quantify and divided into categories (meteorological, agricultural, ecological hydrological), which makes assessing recent changes future scenarios extremely difficult. This opinion piece includes a review scientific literature on topic analyses trends in meteorological droughts by using long-term precipitation records different drought metrics evaluate role global warming processes hydrological severity over last four decades, during sharp increase atmospheric evaporative demand (AED) has been recorded. Meteorological do not show any substantial at scale least 120 years, but an agricultural seems emerge as consequence AED.
