Recent climate impacts on run-of-river hydropower and electricity systems planning in Switzerland
The transition towards renewable energies together with climate change is rendering electricity systems more vulnerable to climate conditions and trends. This study examines the impacts of recent climate change and variability on run-of-river (RoR) hydropower production and electricity systems planning. We present an end-to-end pipeline to convert runoff and hydropower specifications into hydropower generation and subsequently integrate it into a…
Future changes in spatially compounding hot, wet or dry events and their implications for the world’s breadbasket regions
Recent years were characterized by an increase in spatially co-occurring hot, wet or dry extreme events around the globe. In this study we analyze data from multi-model climate projections to analyze the occurrence of spatially compounding events and area affected in future climates under scenarios at +1.5 ∘ C, +2.0 ∘ C, +3.0 ∘ C and higher levels of global warming using Earth System Model simulations from the 6th Phase of the Coupled Model Inter…
Attributing observed permafrost warming in the northern hemisphere to anthropogenic climate change
Permafrost temperatures are increasing globally with the potential of adverse environmental and socio-economic impacts. Nonetheless, the attribution of observed permafrost warming to anthropogenic climate change has relied mostly on qualitative evidence. Here, we compare long permafrost temperature records from 15 boreholes in the northern hemisphere to simulated ground temperatures from Earth system models contributing to CMIP6 using a climate c…
Intergenerational inequities in exposure to climate extremes
Young generations are severely threatened by climate change
Revisiting assessments of ecosystem drought recovery
The time taken for ecosystems to recover from drought (drought recovery time) is critically important for the ecosystem state. However, recent literature presents contradictory conclusions on this feature: one study concludes that drought recovery time in the tropics and high northern latitudes is shortest ( 12 months) in these regions. Here we explore the reasons for these contradictory results and revisit assessments of drought recovery time. W…
Intercomparison of daily precipitation persistence in multiple global observations and climate models
Daily precipitation persistence is affected by various atmospheric and land processes and provides complementary information to precipitation amount statistics for understanding the precipitation dynamics. In this study, daily precipitation persistence is assessed in an exhaustive ensemble of observation-based daily precipitation datasets and evaluated in global climate model (GCM) simulations for the period of 2001–2013. Daily precipitation time…
Evapotranspiration simulations in Isimip2a—Evaluation of spatio-temporal characteristics with a comprehensive ensemble of independent datasets
Actual land evapotranspiration (ET) is a key component of the global hydrological cycle and an essential variable determining the evolution of hydrological extreme events under different climate change scenarios. However, recently available ET products show persistent uncertainties that are impeding a precise attribution of human-induced climate change. Here, we aim at comparing a range of independent global monthly land ET estimates with histori…
Worldwide evaluation of mean and extreme runoff from six global-scale hydrological models that account for human impacts
Global-scale hydrological models are routinely used to assess water scarcity, flood hazards and droughts worldwide. Recent efforts to incorporate anthropogenic activities in these models have enabled more realistic comparisons with observations. Here we evaluate simulations from an ensemble of six models participating in the second phase of the Inter-Sectoral Impact Model Inter-comparison Project (ISIMIP2a). We simulate monthly runoff in 40 catch…
Early warnings of hazardous thunderstorms over Lake Victoria
Weather extremes have harmful impacts on communities around Lake Victoria in East Africa. Every year, intense nighttime thunderstorms cause numerous boating accidents on the lake, resulting in thousands of deaths among fishermen. Operational storm warning systems are therefore crucial. Here we complement ongoing early warning efforts based on numerical weather prediction, by presenting a new satellite data-driven storm prediction system, the prot…
Anthropogenic climate change affects meteorological drought risk in Europe
Drought constitutes a significant natural hazard in Europe, impacting societies and ecosystems across the continent. Climate model simulations with increasing greenhouse gas concentrations project increased drought risk in southern Europe, and on the other hand decreased drought risk in the north. Observed changes in water balance components and drought indicators resemble the projected pattern. However, assessments of possible causes of the repo…
Towards pan-European drought risk maps
Drought in Europe is a hazard with a wide range of transboundary, environmental and socio-economic impacts on various sectors including agriculture, energy production, public water supply and water quality. Despite the apparent importance of this natural hazard, observed pan-European drought impacts have not yet been quantitatively related to the most important climatological drivers to map drought risk on a continental scale. This contribution a…
Todayʼs virtual water consumption and trade under future water scarcity
The populations of most nations consume products of both domestic and foreign origin, importing together with the products the water which is expended abroad for their production (termed 'virtual water'). Therefore, any investigation of the sustainability of present-day water consumption under future climate change needs to consider the effects of potentially reduced water availability both on domestic water resources and on the trades of virtual…
Predicting above normal wildfire activity in southern Europe as a function of meteorological drought
Wildfires are a recurrent feature of ecosystems in southern Europe, regularly causing large ecological and socio-economic damages. For efficient management of this hazard, long lead time forecasts could be valuable tools. Using logistic regression, we show that the probability of above normal summer wildfire activity in the 1985-2010 time period can be forecasted as a function of meteorological drought with significant predictability (p <0.05) se…
