Change of flow Anthropogenic influence on climate has changed temperatures, precipitation, atmospheric circulation, and many other related physical processes, but it river as well? Gudmundsson et al. analyzed thousands time series flows hydrological extremes across the globe compared them with model simulations terrestrial water cycle (see Perspective by Hall Perdigão). They found that observed trends can only be explained if effects change are included. Their analysis shows human affected...
Risk management has reduced vulnerability to floods and droughts globally1,2, yet their impacts are still increasing3. An improved understanding of the causes changing is therefore needed, but been hampered by a lack empirical data4,5. On basis global dataset 45 pairs events that occurred within same area, we show risk generally reduces faces difficulties in reducing unprecedented magnitude not previously experienced. If second event was much more hazardous than first, its impact almost...
Young generations are severely threatened by climate change
Abstract The Paris Agreement of the United Nations Framework Convention on Climate Change aims not only at avoiding +2°C warming (and even limit temperature increase further to +1.5°C), but also sets long‐term goals guide mitigation. Therefore, best available science is required inform policymakers importance and adaptation needs in a +1.5°C warmer world. Seven research institutes from Europe Turkey integrated their competencies provide cross‐sectoral assessment potential impacts...
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...
Abstract. Global water models (GWMs) simulate the terrestrial cycle on global scale and are used to assess impacts of climate change freshwater systems. GWMs developed within different modelling frameworks consider underlying hydrological processes, leading varied model structures. Furthermore, equations describe various processes take forms generally accessible only from individual codes. These factors have hindered a holistic detailed understanding how operate, yet such an is crucial for...
Abstract The extent and impact of climate‐related extreme events depend on the underlying meteorological, hydrological, or climatological drivers as well human factors such land use population density. Here we quantify pure effect historical future climate change exposure to using an unprecedentedly large ensemble harmonized simulations from Inter‐Sectoral Impact Model Intercomparison Project phase 2b. Our results indicate that global warming has already more than doubled both area annually...
Global sustainability is intertwined with freshwater security. Emerging changes in global availability have been recently detected as a combined result of human interventions, natural variability and climate change. Expected future socio-economic climatic will further impact resources. The quantification the impacts challenging due to complexity interdependencies between physical systems. This study demonstrates vulnerability based assessment through conceptual framework, considering...
The main objective of this study was to explore the impact various spectral indices on performance change vector analysis (CVA) for detecting land cover changes island Crete, Greece, between last two decades (1999–2009 and 2009–2019). A set such indices, namely, normalized difference vegetation index (NDVI), soil adjusted (SAVI), albedo, bare (BSI), tasseled cap greenness (TCG), brightness (TCB), representing both conditions area, were estimated Landsat satellite images captured in 1999,...
Abstract Wildfire is an integral part of the Earth system, but at same time it can pose serious threats to human society and certain types terrestrial ecosystems. Meteorological conditions are a key driver wildfire activity extent, which led emergence use fire danger indices that depend solely on weather conditions. The Canadian Fire Weather Index (FWI) widely used index this kind. Here, we evaluate how well FWI, its components, climate variables from derived, correlate with...
Abstract. Floods are one of the most common natural disasters worldwide, leading to economic losses and loss human lives. This paper highlights hydrological effects multi-temporal land use changes in flood hazard within Yialias catchment area, located central Cyprus. A calibrated model was firstly developed describe processes internal basin dynamics three major subbasins, order study diachronic changes. For implementation model, use, soil hydrometeorological data were incorporated. The...
Solar power is the third major renewable energy, constituting an increasingly important component of global future—low carbon—energy portfolio. Accurate climate information essential for conditions solar energy production, maximization, and stable regulation planning. Climate change impacts on output projections are thus crucial importance. In this study effect projected changes in irradiance temperature performance photovoltaic systems Greece examined. were obtained from 5 regional models...

Tourism is highly dependent on the climatic conditions of a given destination. This study examines impact two degrees global warming European summer tourism from climate comfort perspective. The changes in are realized with aid Climatic Index (TCI). Four ENSEMBLES Regional Climate Models (RCMs) provided data for Europe under A1B emission scenario that used analysis potential favorability. Results show change will positively affect central and northern Europe, increasing further economic...
Abstract. Climate models project a much more substantial warming than the 2 °C target under probable emission scenarios, making higher-end scenarios increasingly plausible. Freshwater availability such conditions is key issue of concern. In this study, an ensemble Euro-CORDEX projections RCP8.5 used to assess mean and low hydrological states +4 global for European region. Five major catchments were analysed in terms future drought climatology impact +2 versus was investigated. The effect...
Abstract The European Space Agency (ESA), through the Climate Change Initiative (CCI), is currently providing nearly 4 decades of global satellite‐observed, fully homogenized soil moisture data for uppermost 2–5 cm layer. These are valuable as they comprise one most complete remotely sensed sets available in time and space. One main limitation ESA CCI set limited depth at which content represented. In order to address this critical gap, we (a) estimate calibrate Soil Water Index using...
Abstract Recent studies have shown that temperature and precipitation in the Mediterranean are expected to change, contributing longer more intense summer droughts even extend out of season. In connection this, frequency forest fire occurrence intensity will likely increase. present study, changes future danger conditions assessed for different regions Greece using Canadian weather index (FWI). Gridded climate output as estimated from three regional models Coordinated Regional Downscaling...
Abstract. As the adverse impacts of hydrological extremes increase in many regions world, a better understanding drivers changes risk and is essential for effective flood drought management climate adaptation. However, there currently lack comprehensive, empirical data about processes, interactions, feedbacks complex human–water systems leading to impacts. Here we present benchmark dataset containing socio-hydrological paired events, i.e. two floods or droughts that occurred same area. The...
