Iran’s policy priorities intensify water crisis
Heat-amplifying boreal forests exacerbate snowmelt, fuel availability and wildfires in sub-Arctic regions
Forests, once the largest terrestrial carbon sink, are increasingly becoming significant sources of carbon emissions worldwide due to large wildfires and the accumulation of fire fuels in warming environments that deplete soil and vegetation moisture. Despite growing needs such as Nature-Based Solutions, there is a lack of operationalized near-real-time satellite observations of forest fuel conditions to assess whether forests are acting as carbo…

Balancing thermal power decarbonization and energy security under hydroclimatic risks
Global hydroclimatic risks and strategic decommissioning pathways for thermal power units
Amplifying feedback loop between drought, soil desiccation cracking, and greenhouse gas emissions
The continuous escalation of carbon dioxide (CO2) emissions into the atmosphere is recognized as the primary catalyst for anthropogenic climate change. In 2021, CO2 emerged as the predominant contributor to the warming effect of all human-made greenhouse gases (GHGs), accounting for two-thirds of their global heating impact [1]. While the primary anthropogenic source of increased atmospheric CO2 concentration is the combustion of fossil fuels, th…

Probabilistic modeling of crop-yield loss risk under drought
Assessing the risk of yield loss in African drought-affected regions is key to identify feasible solutions for stable crop production. Recent studies have demonstrated that Copula-based probabilistic methods are well suited for such assessment owing to reasonably inferring important properties in terms of exceedance probability and joint dependence of different characterization. However, insufficient attention has been given to quantifying the pr…
Streamflow droughts aggravated by human activities despite management
Human activities both aggravate and alleviate streamflow drought. Here we show that aggravation is dominant in contrasting cases around the world analysed with a consistent methodology. Our 28 cases included different combinations of human-water interactions. We found that water abstraction aggravated all drought characteristics, with increases of 20%–305% in total time in drought found across the case studies, and increases in total deficit of u…
Large and inequitable flood risks in Los Angeles, California
Increasing cloud water resource in a warming world
Under global warming, terrestrial water resources regulated by precipitation may become more unevenly distributed across space, and some regions are likely to be highly water-stressed. From the perspective of the hydrological cycle, we propose a method to quantify the water resources with potential precipitation capacity in the atmosphere, or hydrometeors that remain suspended in the atmosphere without contributing to precipitation, namely cloud …
The adaptive benefits of agricultural water markets in California
Climate change is expected to increase the scarcity and variability of fresh water supplies in some regions with important implications for irrigated agriculture. By allowing for increased flexibility in response to scarcity and by incentivizing the allocation of water to higher value use, markets can play an important role in limiting the economic losses associated with droughts. Using data on water demand, the seniority of water rights, county …
Intense agricultural irrigation induced contrasting precipitation changes in Saudi Arabia
Groundwater extraction has grown tremendously in Saudi Arabia to meet the irrigation water demand since the 1980s, and irrigation is one of the major anthropogenic factors modulating regional hydroclimate. However, the link between irrigation and hydroclimate is not well understood in a dry region such as Saudi Arabia. In this study, we utilize three different regional climate models to explore the physical mechanisms behind the irrigation impact…
A typology of compound weather and climate events
Climate Extremes and Compound Hazards in a Warming World
Climate extremes threaten human health, economic stability, and the well-being of natural and built environments (e.g., 2003 European heat wave). As the world continues to warm, climate hazards are expected to increase in frequency and intensity. The impacts of extreme events will also be more severe due to the increased exposure (growing population and development) and vulnerability (aging infrastructure) of human settlements. Climate models att…

Changes in the exposure of California’s levee-protected critical infrastructure to flooding hazard in a warming climate
Levee systems are an important part of California’s water infrastructure, engineered to provide resilience against flooding and reduce flood losses. The growth in California is partly associated with costly infrastructure developments that led to population expansion in the levee protected areas. Therefore, potential changes in the flood hazard could have significant socioeconomic consequences over levee protected areas, especially in the face of…
Increasing concurrence of wildfire drivers tripled megafire critical danger days in Southern California between1982 and 2018
Wildfire danger is often ascribed to increased temperature, decreased humidity, drier fuels, or higher wind speed. However, the concurrence of drivers—defined as climate, meteorological and biophysical factors that enable fire growth—is rarely tested for commonly used fire danger indices or climate change studies. Treating causal factors as independent additive influences can lead to inaccurate inferences about shifting hazards if the factors int…
Latitudinal heterogeneity and hotspots of uncertainty in projected extreme precipitation
Projected precipitation from climate models is used in a wide range of fields for climate change impact assessment. However, the spatial pattern of uncertainty across latitudes and the global uncertainty hotspots are not well understood despite their importance for regional adaptation planning. In this study, we describe uncertainties in projected extreme precipitation changes per K global warming across latitudes, and decompose the overall uncer…
Increasing exposure of energy infrastructure to compound hazards
Floods and debris flows pose a significant threat, especially when extreme rain falls over burned areas. This is an example of a compound event in which two concurrent or consecutive events lead to extreme societal impacts. Compound and cascading hazards are becoming increasingly important and have notable impacts on threatened communities across the world. Wildfire followed by an intense precipitation event can result in a large flood under whic…

Climate-informed environmental inflows to revive a drying lake facing meteorological and anthropogenic droughts
The rapid shrinkage of Lake Urmia, one of the world's largest saline lakes located in northwestern Iran, is a tragic wake-up call to revisit the principles of water resources management based on the socio-economic and environmental dimensions of sustainable development. The overarching goal of this paper is to set a framework for deriving dynamic, climate-informed environmental inflows for drying lakes considering both meteorological/climatic and…

Iran’s Socio-economic Drought
Iran is currently experiencing serious water problems. Frequent droughts coupled with over-abstraction of surface and groundwater through a large network of hydraulic infrastructure and deep wells have escalated the nation’s water situation to a critical level. This is evidenced by drying lakes, rivers and wetlands, declining groundwater levels, land subsidence, water quality degradation, soil erosion, desertification and more frequent dust storm…

A near real-time satellite-based global drought climate data record
Reliable drought monitoring requires long-term and continuous precipitation data. High resolution satellite measurements provide valuable precipitation information on a quasi-global scale. However, their short lengths of records limit their applications in drought monitoring. In addition to this limitation, long-term low resolution satellite-based gauge-adjusted data sets such as the Global Precipitation Climatology Project (GPCP) one are not ava…
Changes in concurrent monthly precipitation and temperature extremes
While numerous studies have addressed changes in climate extremes, analyses of concurrence of climate extremes are scarce, and climate change effects on joint extremes are rarely considered. This study assesses the occurrence of joint (concurrent) monthly continental precipitation and temperature extremes in Climate Research Unit (CRU) and University of Delaware (UD) observations, and in 13 Coupled Model Intercomparison Project Phase 5 (CMIP5) gl…
