Temporal Peru Reduced Streamflow2012 199(Baraer et al., 2012)https://doi.org/10.3189/2012JoG11J186The results suggest that seven of the nine study watersheds have probably crossed a critical transition point, and now exhibit decreasing dry-season discharge.
Temporal India Desertification2018 26(Ramarao et al., 2018)https://doi.org/10.1007/s00704-018-2513-6For the period 1951-2005...An assessment of P/PET estimated using the ensemble mean precipitation shows an increase in aridity over several semiarid regions of India...Our results further reveal a 10% expansion in the area of the semiarid regions during recent decades relative to previous decades
Anthropogenic Africa (South) Drought2008 320(Funk et al., 2008)https://doi.org/10.1073/pnas.0708196105Thus, late 20th-century anthropogenic Indian Ocean warming has probably already produced societally dangerous climate change by creating drought and social disruption in some of the world's most fragile food economies
Temporal Africa Drought2009 24(Kniveton et al., 2009)https://doi.org/10.1002/joc.1792From 1978 to 2002, the start of the wet season arrived later in the year for the majority of the region, as time progressed

Warming Global Drought2011 1781(Dai, 2011)https://doi.org/10.1002/wcc.81This article reviews recent literature on drought of the last millennium, followed by an update on global aridity changes from 1950 to 2008...recent warming has increased atmospheric moisture demand and likely altered atmospheric circulation patterns, both contributing to the drying
Warming Global Reduced Streamflow2009 680(Dai et al., 2009)https://doi.org/10.1175/2008JCLI2592.1One-third of the top 200 rivers (including the Congo, Mississippi, Yenisey, Paraná, Ganges, Columbia, Uruguay, and Niger) show statistically significant trends during 1948-2004, with the rivers having downward trends (45) outnumbering those with upward trends (19)... Comparisons with the CLM3 simulation suggest that direct human influence on annual streamflow is likely small compared with climatic forcing during 1948-2004 for most of the world's major rivers.

Temporal California Desertification2011 25(Lam et al., 2011)https://doi.org/10.3390/rs3010001Over a 24-year period (1982, 1988, 1994, 2000, and 2006)...the advancement rate of sand within the Kelso Dunes experienced an encroachment rate of approximately 5.9 m3/m/yr, with advancement accelerating towards the latter half
Warming Mongolia Desertification2013 123(Liu et al., 2013)https://doi.org/10.1371/journal.pone.0057599Here we use a recently developed 21-year (1988-2008) record of satellite based vegetation optical depth (VOD, a proxy for vegetation water content and aboveground biomass), to show that nearly all steppe grasslands in Mongolia experienced significant decreases in VOD. Approximately 60% of the VOD declines can be directly explained by variations in rainfall and surface temperature.
Temporal Africa Drought2012 41(Marshall et al., 2012)https://doi.org/10.1007/s00382-012-1299-yIn this paper, we examine the trends in Ea, precipitation (P), daily maximum temperature (Tmax), and daily minimum temperature (Tmin) on a seasonal basis using a 31 year time series of variable infiltration capacity (VIC) land surface model (LSM) Ea...the historical analysis reveals substantial drying over much of the Sahel and East Africa during the primary growing season
Temporal Africa Drought2014 349Top (Masih et al., 2014)https://doi.org/10.5194/hess-18-3635-2014The study is based on the review and analysis of droughts occurred during 1900-2013 [in Africa]...Most of the studies based on instrumental records indicate that droughts have become more frequent, intense and widespread during the last 50 years.
Temporal Global Desertification2014 98Top (Spinoni et al., 2014)https://doi.org/10.1002/joc.4124We couple the information obtained from the Koppen-Geiger (KG) climate classification and the FAO aridity index (AI), providing an overview of the most evident global changes in climate regimes from 1951-1980 to 1981-2010...Both KG and AI show that the arid areas globally increased between 1951-1980 and 1981-2010...North-Eastern Brazil, Southern Argentina, the Sahel, Zambia and Zimbabwe, the Mediterranean area, North-Eastern China and Sub-Himalayan India have been identified as areas with a significant increase of drylands extent.

Temporal Iberian Peninsula Drought2017 39(Pascoa et al., 2017)https://doi.org/10.1155/2017/4653126The long-term evolution of drought in the Iberian Peninsula is analyzed...for the period of 1901-2012...SPEI identified dryer conditions and an increase in the area affected by droughts.
Temporal Asia Drought2015 21(Son and Bae, 2015)https://doi.org/10.1016/j.jhydrol.2015.09.010For the period of 1963-2006...annual precipitation and runoff in the SAC regions appeared to decrease about 12.1% and 27.3%, respectively...Frequency and duration of droughts in the SAC regions were observed to increase about 9.2 and 1.5 months, respectively, and drought severity index intensified to about -0.15.
Temporal Europe (South) Drought2015 120(Spinoni et al., 2015)https://doi.org/10.1016/j.gloplacha.2015.01.0...A linear trend analysis shows that drought variables increased in the period 1950-2012 in South-Western Europe, in particular in the Mediterranean and Carpathian regions,
Warming Global Drought2019 105(Spinoni et al., 2019)https://doi.org/10.1016/j.ejrh.2019.100593We constructed a database of meteorological drought events from 1951 to 2016...Over North America, central Europe, central Asia, and Australia, the recent progressive temperature increase outbalanced the increase in precipitation causing more frequent and severe droughts.
Warming Iberian Peninsula Drought2014 408(Vicente-Serrano et al., 2014)https://doi.org/10.1088/1748-9326/9/4/044001We use high quality climate data from ground meteorological stations in the Iberian Peninsula (IP) and robust drought indices to confirm that drought severity has increased in the past five decades, as a consequence of greater atmospheric evaporative demand resulting from temperature rise.
Temporal China Desertification2019 8(Yin et al. 2019)https://doi.org/10.1007/s00382-018-4139-xWe delineated the AHCR of China using information about the balance of the atmospheric water supply and demand collected from 581 meteorological stations over the past 50 years...results indicate that the semi-arid region expanded significantly over the last five decades, mainly in northwest China, northern China, and the Tibetan Plateau and, by the 2000s, had increased by 33.53% relative to its extent in the 1960s.
Warming Nigeria Desertification2017 42(Obioha, 2017)https://doi.org/10.1080/09709274.2008.1190608...In the recent times, due to the increasing rate of global warming, the northeast region of Nigeria has been experiencing continuous climatic change characterized by drastic reduction in rainfall, increase in the rate of dryness and heat, which makes it a fast growing arid environment, with depletion in the amount of water, flora and fauna resources on the land.
Anthropogenic Global Drought1998 308(Dai et al., 1998)https://doi.org/10.1029/98GL52511Since the late 1970s, however, there have been some increases in the combined percentage areas in severe drought and severe moisture surplus, resulting from increases in either the drought area (e.g., over the Sahel, eastern Asia and southern Africa) or both the drought and wet areas (e.g., over the U.S. and Europe)...These changes are qualitatively consistent with those expected from increased greenhouse gases in the atmosphere.
Anthropogenic Global Drought2004 1544(Dai et al., 2004)https://doi.org/10.1175/JHM-386.1The global very dry areas, defined as PDSI < −3.0, have more than doubled since the 1970s, with a large jump in the early 1980s due to an ENSO-induced precipitation decrease and a subsequent expansion primarily due to surface warming...these results provide observational evidence for the increasing risk of droughts as anthropogenic global warming progresses and produces both increased temperatures and increased drying.
Anthropogenic Australia Drought2004 240(Nicholls, 2004)https://doi.org/10.1023/B:CLIM.0000018515.463...Rainfall over nearly all of Australia during the cooler half of the year (May-October) was well below average in 2002...drought conditions (precipitation minus evaporation) were worse than in previous recent periods with similarly low rainfall (1982, 1994). Mean minimum temperatures were also much higher during the 2002 drought than in the 1982 and 1994 droughts...The possibility that the enhanced greenhouse effect is increasing the severity of Australian droughts...needs to be considered.
Temporal China Drought2009 331(Zhou et al., 2009)https://doi.org/10.1127/0941-2948/2009/0396Over the recent decades, the EASM [East Asian summer monsoon] has been weakening from the end of the 1970s which results in a "southern China flood and northern China drought" rainfall pattern...the pronounced weakening tendency of the EASM in recent decades is unprecedented.
Temporal Sierra Leone Drought2019 8(Wadsworth et al., 2019)https://doi.org/10.3390/cli7120144Sierra Leone on the west coast of Africa has a monsoon-type climate...changes in rainfall over the last four decades are examined...there is evidence for a significant reduction in annual rainfall in the northwest.
Temporal Horn of Africa Drought2019 47(Haile et al., 2019)https://doi.org/10.1016/j.scitotenv.2019.1352...The results showed that despite regional differences, an overall increasing tendency of drought was observed across the [Greater Horn of Africa] over the past 52 yr, with trends of change of -0.0017 yr-1, -0.0036 yr-1, -0.0031 yr-1, and -0.0023 yr-1 for SPEI-01, SPEI-03, SPEI-06, and SPEI-12, respectively.
Temporal Nigeria Drought2018 81(Shiru et al., 2018)https://doi.org/10.3390/su10030871Gauge-based gridded rainfall and temperature data for the period 1961-2010 [for Nigeria] with spatial resolutions of 0.5deg were used...The occurrences of droughts, particularly moderate droughts with smaller areal extents, were found to increase for all of the seasons
Warming Nigeria Drought2019 70(Shiru et al., 2019)https://doi.org/10.1016/j.atmosres.2019.03.01...Nigeria for the period 1901-2010...a general decrease in the return periods of droughts indicates more frequent droughts during all cropping seasons of Nigeria. Therefore, it can be concluded that the rising temperature due to global warming would increase drought severity and frequency in all the cropping seasons of Nigeria.
Temporal Bangladesh Drought2019 29(Kamruzzaman et al., 2019)https://doi.org/10.3390/w11122437In Bangladesh...monthly precipitation data for 36 years (1980-2015) obtained from 27 metrological stations, were used in this study...The frequency of droughts in all categories significantly increased during the last quinquennial period (2011 to 2015).
Temporal Caribbean Drought2017 54(Herrera and Ault, 2017)https://doi.org/10.1175/JCLI-D-16-0838.1Climate change is expected to increase the severity and frequency of drought in the Caribbean...this work introduces a first of its kind high-resolution drought dataset for the Caribbean region from 1950 to 2016...linear trends in the scPDSI show a significant drying in the study area, averaging an scPDSI change of -0.09 decade-1 (p < 0.05).
Warming Global Drought2019 25Top (Peng et al., 2019)https://doi.org/10.1016/j.gloplacha.2019.04.0...Since the late 1940s, drylands have increased at a rate of 512,180 km2/decade. The main feature is the sharp jump in drylands expansion in the 1980s, with the area of drylands increasing 3.1% (1.90 x 106km2) between 1980 and 2008 compared to 1948-1979...rapid warming since the 1980s has become an increasing important cause of the recent global drying trend.
Anthropogenic China Drought2020 18Top (Li et al., 2020)https://doi.org/10.1029/2019EA000836The results show that summer hot drought events over northeastern China increased from 1961 to 2005...increased greenhouse gases emission forcing (GHG), and anthropogenic forcing (ANT) can largely reproduce the spatial and temporal features of the trends of summer hot drought events over northeastern China.
Warming Baja California Drought2020 5(Guerrero and Kretzschmar, 2020)https://doi.org/10.1016/j.ejrh.2019.100653We detected an abrupt downward change in annual precipitation in 1998, and a continuous period of reduction in precipitation rate from 1999 to 2016 (at least 17 years)...and an increase in dry seasonal/annual periods after 1998...also, we detected an upward change in maximum temperature...and an increase in dry seasonal/annual periods after 1998...the decrease of precipitation and increase in temperature have had negative impacts on groundwater availability that have affected agriculture and population.
Temporal China Drought2020 11(Han et al., 2020)https://doi.org/10.1002/joc.6527In China from 1950 to 2009...the annual and seasonal drought intensities have increased slightly in the past 60 years, while the disturbed area has broadened significantly, especially in eastern China which has become much drier than before.

Temporal Brazil Drought2020 40(Costa et al., 2020)https://doi.org/10.1016/j.wace.2020.100254Over the northeast region of Brazil for the period of 1961-2014...in most weather stations where there is a significant increase in consecutive dry days, there is also a trend of significant increase in consecutive wet days, thereby intensifying the seasonality, with the dry seasons becoming drier and the rainy seasons wetter.
Warming Global Drought2020 7(Zhang et al., 2020)https://doi.org/10.1002/joc.6555During 1980-2010, due to significant global warming (0.30 C decade -1) the global mean occurrence frequency of [short-term concurrent hot and dry extreme events] has a slightly increasing trend (0.34% decade -1)
Warming Europe Drought2019 56(Manning et al., 2019)https://doi.org/10.1088/1748-9326/ab23bf[In Europe] during the summer months of June, July and August...over the historical period 1950-2013...we find an increased probability of dry and hot events throughout Europe where rising temperatures are found to be the main driver of this change...the results point to a predominant thermodynamic response of dry and hot events to global warming and reaffirm previous research that soil moisture drought events are setting in faster and becoming more severe.
Anthropogenic China Drought2017 83Top (Chen and Sun, 2017)https://doi.org/10.1016/j.jhydrol.2016.11.044Drought occurrences across China increased consistently during 1951-2014, especially during the recent twenty years...external natural forcings were mainly responsible for the variability of droughts and anthropogenic influences for their increasing trends, suggesting that anthropogenic warming has increased hot drought occurrences, associated risks and impacts across China.
Temporal Spain Drought2014 14(Andrade & Belo-Pereira, 2014)https://doi.org/10.1002/asl2.542In western and central regions of [Iberian Peninsula]...an increase in the drought frequency since the 1980s is found during the months of winter and spring. These outcomes are consistent with the downward precipitation trends detected for these seasons in several studies.
Warming China Groundwater2007 502(Cheng & Wu, 2007)https://doi.org/10.1029/2006JF000631Numerous studies have reported permafrost degradation under climate warming in the 20th century in the Northern Hemisphere...long-term temperature measurements indicate that the lower altitudinal limit of permafrost has moved up by 25 m in the north during the last 30 years...permafrost degradation is one of the main causes responsible for a dropping groundwater table at the source areas of the Yangtze River and Yellow River, which in turn results in lowering lake water levels, drying swamps and shrinking grasslands.
Anthropogenic United States Reduced Streamflow2020 56(Overpeck & Udall, 2020)https://doi.org/10.1073/pnas.2006323117In the American Southwest, where declining flows in the region's two most important rivers, the Colorado (Fig. 1) and Rio Grande, have been attributed in part to increasing temperatures caused by human activities...warming is also causing flow declines in the northern Rocky Mountains and in the largest river basin in the United States, the Missouri
Warming Montenegro Drought2020 5(Buric & Doderovic, 2020)https://doi.org/10.1002/joc.6671For the period 1951-2018...Podgorica's climate has become more arid and extreme, as the number of days with precipitation >= 1 mm (R1) has significantly decreased.
Anthropogenic Chile Drought2015 189(Boisier et al., 2015)https://doi.org/10.1002/2015GL067265A precipitation decline, of consistent direction but of larger amplitude than obtained in simulations with historical climate forcing, has been observed in central Chile since the late 1970s...unlikely to be driven exclusively by natural phenomena but rather consistent with the simulated regional effect of anthropogenic climate change.
Temporal Iran Drought2014 107(Golian et al., 2014)https://doi.org/10.1007/s00704-014-1139-6From 1980 to 2013...the Mann-Kendall trend test shows that the northern, northwestern, and central parts of Iran have experienced significant drying trends at a 95 % confidence level.
Anthropogenic Syria Drought2012 253(Hoerling et al., 2012)https://doi.org/10.1175/JCLI-D-11-00296.1A change in wintertime Mediterranean precipitation toward drier conditions has likely occurred over 1902-2010 whose magnitude cannot be reconciled with internal variability alone. Anthropogenic greenhouse gas and aerosol forcing are key attributable factors for this increased drying.
Anthropogenic Australia Drought2014 106(Delworth & Zeng, 2014)https://doi.org/10.1038/ngeo2201Precipitation in austral autumn and winter has declined over parts of southern and especially southwestern Australia in the past few decades...in our simulations, many aspects of the observed regional rainfall decline over southern and southwest Australia are reproduced in response to anthropogenic changes in levels of greenhouse gases and ozone in the atmosphere
Warming United States Reduced Streamflow2009 193(Luce & Holden, 2009)https://doi.org/10.1029/2009GL039407The changing climate and water cycle of the Western U.S. are impacting water resources...the driest 25% of years are getting drier across the majority of the Pacific Northwest. The change is substantial, with most streams showing decreases exceeding 29% and some showing decreases approaching 50% between 1948 and 2006.
Warming Brazil Drought2020 74(Morales et al., 2020)https://doi.org/10.1073/pnas.2002411117The South American Drought Atlas shows that the frequency of widespread severe droughts and extreme pluvials since the 1960s is unprecedented.
Temporal Norway Drought2010 166(Wilson et al., 2010)https://doi.org/10.1016/j.jhydrol.2010.09.010For three periods: 1920-2005, 1941-2005 and 1961-2000...a signal towards earlier snowmelt floods was clear, as was the tendency towards more severe summer droughts in southern and eastern Norway.
Warming Egypt Drought2020 12(Sahour et al., 2020)https://doi.org/10.1007/s00704-020-03370-6Available water resources in the Middle East, as one of the most water-scarce regions of the world, have undergone extra pressure due to climatic change...at an annual time scale, 62.5% of the detected trends in aridity were found to be upward (up to 96% increase) due to the combined effects of the decrease in precipitation and the increase in potential evapotranspiration.
Anthropogenic China Drought2020 11(Chen, 2020)https://doi.org/10.1088/1748-9326/abb1f1During 1970-2017...the intra-seasonal distribution of precipitation, in both frequency and amount, has been getting significantly more uneven...suggesting detectable contributions from anthropogenic climate change...the increased unevenness has led to significant lengthening of the longest dry spells
Temporal India Reduced Rainfall2020 5(Sah et al., 2020)https://doi.org/10.1007/s00704-020-03421-yThis study examined the long-term (1951-2015) spatio-temporal trends, variability, and teleconnections of rainfall of 15 districts in the Terai region of Uttar Pradesh, India...our analysis revealed significantly declining trends in monthly rainfall for most of the districts in all the months, except February, April, May, and December...in seasonal and annual rainfall data, only decreasing trends were significant.
Warming Pakistan Reduced Streamflow2021 13(Latif et al., 2021)https://doi.org/10.1007/s00704-021-03529-9The present study concludes that Upper Indus Basin's vulnerability is growing in terms of significantly increased temperature, reduced precipitation, and eventually decreased river flows during the recent period from 1991 to 2013.

Warming Iran Drought2021 3(Sadeqi & Kahya, 2021)https://doi.org/10.1007/s00704-021-03658-1Using a long-term meteorological data (1960-2019) of 31 synoptic stations throughout Iran...our results revealed that the climate in Iran, in general, has become warmer and drier in the past 60 years and continuation of the current global warming trend will exacerbate this problem in the future.
Warming Pakistan Drought2021 24(Ullah et al., 2021)https://doi.org/10.1002/joc.7321The present work sought to investigate the spatiotemporal changes in drought characteristics over Pakistan during Rabi and Kharif cropping seasons...monthly precipitation and temperature data (1983-2019) from 53 meteorological stations...revealed an increase in drought severity, mostly over arid to semi-arid regions for both cropping seasons.
Warming China Drought2021 4(Sun et al., 2021)https://doi.org/10.1016/j.gloplacha.2021.1036...Observations indicate a significant increasing trend in drought severity in [northern East Asia]...correlation analysis indicates that the intensification of drought in NEA is strongly related to the changes in average temperature and related ECIs
Anthropogenic Global Drought2022 2(Zhang et al., 2022)https://doi.org/10.1088/1748-9326/ac43e0In this study, we provide evidence that anthropogenic forcings have contributed to the increased compound dry and hot events (CDHEs) over global land areas...the results show observed occurrences of CDHEs have increased over most regions across global land areas during 1956-2010 relative to 1901-1955...we find anthropogenic influences have increased the risk of CDHEs in large regions across the globe except for parts of Eurasia and North America.
Warming Iran Reduced Streamflow2022 1(Mahmoodi et al., 2022)https://doi.org/10.1007/s13762-021-03432-wStreamflow records from eight sites of the Dez River Basin, Iran, were analyzed by a modified Mann-Kendall test to examine possible trends in annual and monthly time series of streamflow...the results showed significant negative trends in the streamflow time series of the warm months (April, May, June, July, August, and September) over 34 year-long records.
Temporal Kazakhstan Drought2022 5(Ren et al., 2022)https://doi.org/10.1175/JCLI-D-21-0329.1Our results indicated that the dry season became drier while the wet season became wetter in Central Asia for 1982-2019
Temporal Global Aridity2022 9Top (Ullah et al., 2022)https://doi.org/10.1016/j.atmosres.2021.10599...The present study assessed spatiotemporal changes in global aridity over the period 1901-2019, using five aridity indices...except for the AIunep index, the rest of the indices displayed an obvious and consistent increase in aridity over Northern Hemisphere...the increase (decrease) in temperature (soil moisture) has intensified the process of potential evapotranspiration (PET) and aridity across the globe.
Anthropogenic Mongolia Reduced Streamflow2019 (Zorigt et al., 2019)https://doi.org/10.1007/s10113-019-01564-xMonthly and maximum runoff, precipitation, and air temperature data from 12 gauging stations collected between 1978 and 2015 were analyzed to characterize the hydrological regime response to climate change...river runoff in the Mongolian part of the Selenge basin has decreased from the first interval (1978-1995) of our study period compared with the consecutive interval from 1996 to 2015
Temporal China Drought2020 (Li et al., 2020)https://doi.org/10.1007/s00703-020-00727-4Drought is one of the major natural disasters in northern China...in the Inner Mongolian Plateau from 1962 to 2017...the degree of drought in the study area has increased.
Warming United States Reduced Streamflow2020 (Martin et al., 2020)https://doi.org/10.1073/pnas.1916208117We find that temperature has increasingly influenced the severity of drought events by decreasing runoff efficiency in the [Upper Missouri River Basin] since the late 20th century (1980s) onward. The occurrence of extreme heat, higher evapotranspiration, and associated low-flow conditions across the basin has increased substantially over the 20th and 21st centuries.
Warming Oman Drought2020 (Kenawy et al., 2020)https://doi.org/10.1016/j.atmosres.2020.10512...Spatial and temporal variability of drought in Oman was assessed for the period 1979-2014...results suggest a statistically significant increase in the frequency and severity of drought during the past four decades...the significant temperature rise in recent decades, combined with a significant decline of rainfall and relative humidity, can explain the prolonged drought episode lasting from 1998 to 2014.
Warming Dominican Republic Drought2022 (Zermeno-Diaz, 2022)https://doi.org/10.1002/joc.7621During the last decades, the variability of the Caribbean precipitation has been characterized by dry trends over land...the results suggest that the dry trends might have been intensified by the land-sea contrast trend that has characterized the effects of global warming
Warming Europe Drought2022 (Hansel et al., 2022)https://doi.org/10.1002/joc.7587Long-term variations in drought and five record drought summer half years are studied based on 63 stations across Europe with high-quality precipitation and temperature time series spanning the period 1901-2018...The aggregated drought evaluation index (ADE) shows increasing summer drought conditions over most of Europe, except for some stations in northern Europe.
