Caste Inequality in Occupational Exposure to Heat Waves in India
India is a leading global hot spot for extreme heat waves induced by climate change. The social demography of India is centered on its caste hierarchy rooted in endogamous occupational groups. We investigate the association between caste and climate inequality by studying occupational exposure during the 2019 and 2022 heat waves. We combine high spatiotemporal resolution heat stress information from satellite imagery with a large nationally and r…

Global evidence of rapid flash drought recovery by extreme precipitation
Flash drought affects agricultural activities and water availability. However, the rate of flash drought development and termination and their controlling mechanisms remain mostly unexplored. Using climate reanalysis (ERA5) datasets, we examine the flash drought development and recovery rates in seventeen climate regions across the globe during the 1981–2020 period. In most global climate regions, flash drought recovery (25.2 percentile/pentad) i…
Excessive pumping limits the benefits of a strengthening summer monsoon for groundwater recovery in India
Increasing risk of simultaneous occurrence of flash drought in major global croplands
Simultaneous occurrence of flash drought in major croplands can pose challenges for global food security. However, drivers of flash drought co-occurrence in the observed and future climate remain unrecognized. Using observations and climate model simulations, we examine the simultaneous occurrence of flash droughts in 16 major global croplands that grow wheat, rice, and maize. We show that significant warming combined with decreasing precipitatio…
The 2022 mega heatwave in South Asia in the observed and projected future climate
The heatwave in 2022 in South Asia disrupted the lives of millions of people and posed challenges to human health, energy, water, and food security. However, mega heatwaves’ causes, impacts, and occurrence (like in 2022) remain largely unrecognized. Here, we analyzed the 2022 heatwave, its mechanisms, and future likelihood using observational datasets and climate model simulations. In the last few years, the frequency and duration of heatwaves ha…
Enhanced risk of concurrent regional droughts with increased Enso variability and warming
Warming climate and Enso variability enhance the risk of sequential extremes in India
A framework to incorporate spatiotemporal variability of rainfall extremes in summer monsoon declaration in India
The Indian summer monsoon rainfall is a lifeline for agricultural activities and the socio-economic development of more than 1 billion people. All-India averaged summer monsoon rainfall has about 10% variability from its long-term mean. A departure of all-India averaged precipitation within ±10% is declared a normal summer monsoon. Using the long-term (1901–2021) gridded rainfall observations, we highlight the limitations in the current approach …
Increasing footprint of climate warming on flash droughts occurrence in Europe
Flash droughts are caused by a rapid depletion of soil moisture, and they severely affect vegetation growth and agricultural production. Notwithstanding the growing importance of flash droughts under the warming climate, drivers of flash droughts across the Europe are not well understood. Here we estimate the changes in flash droughts characteristics across Europe using the ERA5 reanalysis dataset for 1950–2019 period. We find a substantial incre…

Natural and anthropogenic drivers of the lost groundwater from the Ganga River basin
Ganga river basin is the most populated and among the worst water-stressed river basins in the world. The basin contributes to 40% of India’s gross domestic product. Despite the Ganga basin’s cultural, heritage, and economic importance, the interplay among the crucial factors that make the basin one of the global groundwater depletion hotspots is not well understood. Using observations from wells and Gravity Recovery and Climate Experiment satell…
Unprecedented drought in South India and recent water scarcity
Peninsular Indian agriculture and drinking water availability are critically reliant on seasonal winter rainfall occurring from October to December, associated with the northeastern monsoon (NEM). Over 2016–2018, moderate-to-exceptionally low NEM rainfall gave rise to severe drought conditions over much of southern India and exacerbated water scarcity. The magnitude and dynamics of this drought remain unexplored. Here, we quantify the severity of…
Changes in Physician Telemedicine Use during Covid-19: Effects of Practice Setting, Demographics, Training, and Organizational Policies
Telemedicine use increased during the COVID-19 pandemic, but uptake was uneven and future use is uncertain. This study, then, examined the ability of personal and environmental variables to predict telemedicine adoption during the COVID-19 pandemic. A total of 230 physicians practicing in the U.S. completed questions concerning personal and environmental characteristics, as well as telemedicine use at three time points: pre-pandemic, during the p…
On the occurrence of the worst drought in South Asia in the observed and future climate
Droughts in South Asia pose substantial challenges to water resources, agricultural, and socio-economic growth of more than two billion people. However, the most detrimental soil moisture droughts, their impacts, and occurrence in the observed and projected climate in South Asia remain unidentified. We conducted soil moisture simulations using the variable infiltration capacity model and meteorological forcing based on the four global observation…
Substantial decline in atmospheric aridity due to irrigation in India
Compound extremes of soil moisture (SM) drought and high vapor pressure deficit (atmospheric aridity) are disastrous for natural and social systems. Despite a significant expansion in irrigated area in India, the role of irrigation on SM and atmospheric aridity is not examined. We used observations, reanalysis datasets, and high-resolution simulations from the Weather Research and Forecasting (WRF) model to show that irrigation significantly modu…
Dominance of summer monsoon flash droughts in India
Flash droughts intensify rapidly after onset and cause short-term but devastating impacts on agriculture and the ecosystem. However, the drivers and characteristics of flash droughts in India have not been examined. Here we use a well-calibrated and evaluated variable infiltration capacity (VIC) hydrological model to simulate root-zone soil moisture to identify flash droughts in India for 1951–2018 period. We show that flash droughts predominantl…
A seven-fold rise in the probability of exceeding the observed hottest summer in India in a 2 °C warmer world
Heatwaves and extreme temperatures during summer (April–May) in India have profound implications on public health, mortality, water availability, and productivity of labourers. However, how the frequency of the hottest summers in observed record (1951–2015) will change under the warming climate in India is not well explored. Using observations from the India Meteorological Department, we show that mean maximum summer temperature has increased sig…
Intercomparison of regional-scale hydrological models and climate change impacts projected for 12 large river basins worldwide—a synthesis
An intercomparison of climate change impacts projected by nine regional-scale hydrological models for 12 large river basins on all continents was performed, and sources of uncertainty were quantified in the framework of the ISIMIP project. The models ECOMAG, HBV, HYMOD, HYPE, mHM, SWAT, SWIM, VIC and WaterGAP3 were applied in the following basins: Rhine and Tagus in Europe, Niger and Blue Nile in Africa, Ganges, Lena, Upper Yellow and Upper Yangt…
Changes in observed climate extremes in global urban areas
Climate extremes have profound implications for urban infrastructure and human society, but studies of observed changes in climate extremes over the global urban areas are few, even though more than half of the global population now resides in urban areas. Here, using observed station data for 217 urban areas across the globe, we show that these urban areas have experienced significant increases ( p -value <0.05) in the number of heat waves durin…
