Early 21st-century droughts in Europe have been broadly regarded as exceptionally severe, substantially affecting a wide range of socio-economic sectors. These extreme events were linked mainly to increases temperature and record-breaking heatwaves that influencing since 2000, combination with lack precipitation during the summer months. Drought propagated through all respective compartments hydrological cycle, involving low runoff prolonged soil moisture deficits. What if these recent are not previously thought? Using reconstructed over last 250 years, we show although 2003 2015 may be most driven by deficits vegetation period, their spatial extent severity at long-term European scale less uncommon. This conclusion is evident our concurrent investigation three major drought types - meteorological (precipitation), agricultural (soil moisture) (grid-scale runoff) droughts. Additionally, unprecedented drying trends for corresponding frequency also observed, reflecting recurring periods high temperatures. Since intense extended reemerge future, study highlights concerns regarding impacts such when combined persistent decrease moisture.

Abstract. Billions of people rely on groundwater as being an accessible source drinking water and for irrigation, especially in times drought. Its importance will likely increase with a changing climate. It is still unclear, however, how climate change impact systems globally and, thus, the availability this vital resource. Groundwater recharge important indicator availability, but it flux that difficult to estimate uncertainties balance accumulate, leading possibly large errors particular dry regions. This study investigates projections using multi-model ensemble eight global hydrological models (GHMs) are driven by bias-adjusted output four circulation (GCMs). Pre-industrial current values compared different warming (GW) levels result three representative concentration pathways (RCPs). Results suggest projected changes strongly vary among GHM–GCM combinations, statistically significant only computed few regions world. Statistically GWR increases northern Europe some parts Arctic, East Africa, India. decreases simulated southern Chile, Brazil, central USA, Mediterranean, southeastern China. In regions, reversals trends can be observed warming. Because most GHMs do not simulate atmospheric CO2 vegetation evapotranspiration, we investigate estimated affected inclusion these processes. leads differences up 100 mm per year. Most active less severe than without even instead simulated. However, where GCMs predict precipitation important, model agreement lowest. Overall, outcomes additional research simulating processes necessary.

Abstract River discharge is an Essential Climate Variable (ECV) and one of the best monitored components terrestrial water cycle. Nonetheless, gauging stations are distributed unevenly around world, leaving many white spaces on global freshwater resources maps. Here, we use a machine learning algorithm historical weather data to upscale sparse in situ river measurements. We provide reanalysis monthly runoff rates for periods covering decades past century at resolution 0.5° (about 55 km), with up 525 ensemble members based 21 different atmospheric forcing sets. This reconstruction, named Global RUNoff ENSEMBLE (G‐RUN ENSEMBLE), evaluated using independent observations from large basins benchmarked against other publicly available sets over period 1981–2010. The accuracy set observed flow not used model calibration found compare favorably state‐of‐the‐art hydrological simulations. G‐RUN estimates mean volume range between 3.2 × 10 4 3.8 km 3 yr −1 . ( https://doi.org/10.6084/m9.figshare.12794075 ) has wide applications, including regional assessments, climate change attribution studies, hydro‐climatic process studies as well evaluation, refinement models.

Abstract The Mediterranean basin is particularly prone to climate change and vulnerable its impacts. One of the most relevant consequences change, especially for southern regions, certainly water scarcity as result a reduction surface runoff groundwater levels. Despite progress achieved in recent years field impact on resources, results outcomes should be treated with due caution since any future projection derived implications are inevitably affected by certain degree uncertainty arising from each different stage entire modeling chain. This work offers comprehensive overview works basin, mainly focusing last ten research. Past trends components hydrological balance discussed companion paper (Noto et al. 2022), while present focuses problem availability scarcity. In addition, aims discuss sources related aim gain awareness studies interpretation reliability.
