As global temperatures rise, extreme heat events are projected to become more frequent and intense. Extreme heat causes a wide range of health effects, including an overall increase in morbidity and mortality. It is important to note that while there is sufficient epidemiological evidence for heat-related increases in all-cause mortality, evidence...

The short term effect of multiple air pollutants e.g. aerosols (black carbon, BC; PM2.5 and PM10) and trace gases (NO2, SO2, and O3) on all-cause mortality was systematically investigated in a typical urban pollution hotspot over central Indo-Gangetic Plain (IGP). To our knowledge, this would be the first report of mortality estimates for exposure...

The urban population has increased from about 750 million in 1951 to 4.2 billion in 2018. This uncontrolled population growth has resulted in an unplanned, fast and unsustainable urban development. Due to this, environmental conditions at the local and global ecosystem levels have deteriorated. However, the public health aspect of urban ecology has...

Climate extremes are often associated with increased human mortality and such association varies considerably with space and time. We therefore, aimed to systematically investigate the effects of temperature extremes, daily means and diurnal temperature variations (DTV) on mortality in the city of Varanasi, India during 2009-2016. Time series data...

The effects of climate on infectious-diseases could influence the health impacts, particularly in children in countries with unfair socioeconomic condition. In a prospective cohort of 461 children under 16-years-of-age in Varanasi-city, India, the association of maximum-temperature (Tmax), relative-humidity (RH), absolute-humidity (AH), rainfall (R...

Background: There is no doubt that global warming, with its extreme heat events, is having an increasing impact on human health. Heat is not independent of ambient temperature but acts synergistically with relative humidity (RH) to increase the risk of several diseases, such as cardiovascular and pulmonary diseases. Although the skin is the organ i...

Background Temperature and relative humidity (RH) impact human health. However, little is known about the combined association between temperature and RH on respiratory health in the elderly. In this study, we evaluated the interactive associations of temperature and RH on airway obstruction in elderly German women. Methods Using data from the sec...

Given that people spend the majority of their time indoors, accurate measurement of pollutants in indoor environment settings is critical especially when the levels of air pollution often surpass those of outdoor environments. While extensive studies have been focussed on outdoor air quality, limited studies have examined indoor air quality in a re...

Background Relative humidity (RH) and air pollution significantly affect respiratory health. However, how RH and air pollution interact and modify each other and affect lung function in adolescence is largely unknown. This study assesses the interactive association of RH and air pollution on lung function, i.e. forced vital capacity (FVC) and force...

Fraction of exhaled Nitric Oxide (FeNO) is a marker of airway inflammation. We examined the main effects and interactions of relative humidity (RH) and air pollution on adolescents’ FeNO. Two thousand and forty-two participants from the 15-year follow-up of the German GINIplus and LISA birth cohorts were included. Daily meteorological (maximum [Tma...

Multi-model climate projections are increasingly used to quantify the impacts of climate change on major staple crops under different climate change scenarios. Despite uncertainty associated with different climate projections, it helps in providing a direction and magnitude of change in crop production in future with different uncertainty levels. I...

https://doi.org/10.1093/bjd/ljad008 The rising global prevalence of skin diseases and related disabilities has elevated this category of illnesses to the fourth most common cause of nonfatal disease burden in recent decades, and skin diseases can be highly climate sensitive.¹ In addition to other environmental and genetic determinants, both climate...

Diurnal temperature range (DTR) which reflects the difference between the daily maximum (Tmax) and minimum temperature (Tmin) is an important indication of changing climate and a critical thermal metric to assess the impact on agriculture, biodiversity, water resources, and human health. The major aim of this study is to assess the probable future...

It has now been well established that the rise in global mercury has driven climate change phenomena that have led to extreme temperature events, sea level rise, change in the hydrological cycle, frequent droughts and floods, and cyclones and forest fires and caused a myriad of adverse impacts on vital worldwide sectors such as agriculture, water a...

Regional climate models (RCMs) are routinely applied for regional climate assessments. The RCM simulated rainfall typically overpredict the light rain/drizzle events. To correct the typical errors noted in RCM rainfall simulations, in this study, three bias‐correction methods: linear scaling (SCL), local intensity scaling (LOCI), and empirical quan...

Diurnal temperature range (DTR) is an important indicator of climatic change and a critical thermal metric to assess the impact on agriculture and human health. This study investigates the seasonal, annual and decadal changes in the spatio‐temporal trend in DTR and air temperatures (maximum: Tmax and minimum: Tmin) during 1951–2016 and solar radiat...

India and other Southeast Asian countries are severely affected by Japanese encephalitis (JE), one of the deadliest vector-borne disease threat to human health. Several epidemiological observations suggest climate variables play a role in providing a favorable environment for mosquito development and virus transmission. In this study, generalized a...

Heat wave (HW) and severe heat wave (SHW) events are the manifestations of extreme temperature causing an array of impacts on health, ecosystem, and economy. Since the mid‐20th century, an increasing trend in the characteristics of heat waves has been observed over India causing an increased rate in human mortality. Our study aimed to analyse month...

CANEGRO-Sugarcane model was used to assess the impact of climate change on sugarcane in different combinations of elevated temperature and CO2 concentration. Additionally, we used dynamically downscaled bias-corrected regional climate model (RCM) data using RegCM4 under RCP4.5 scenarios (2040–2060) to project the future change in sugarcane stalk fr...

Potential impact of change in climate on Indian agriculture may be significantly adverse, if not disastrous. There are projections of potential loss in wheat yield due to the rise in daily minimum (Tmin) and maximum (Tmax) temperature, but only few researchers have considered the extent of such loss on a spatial scale. We therefore, systematically...

Climate variability impacts the components of hydrological cycle especially evapotranspiration (ET) and soil moisture, that plays a crucial role in determining water flux of an agriculture system and is thus, essential to study the response of ET to climate change. The present study is an attempt to understand the trend in observed ET (1978–2003) a...

Heat extremes are observed as Heat Waves (HW) and Severe Heat Waves (SHW) during pre-monsoon and early summer monsoon season during March-July over India. Studies suggest a marked change in the characteristics of heat waves and severe heat waves in recent decades observing an increasing trend in the intensity, frequency and duration of their occurr...

Diurnal Temperature Range (DTR) has been recently used in several study as a temperature metric to assess the additional burden of mortality due to unusual temperature. Importantly most of the studies have reported the mortality burden due to increase in DTR as the places where the studies were performed have very low mean temperature in compared t...

The entire Indo-Gangetic Basin (IGB) has long been exposed to high ambient particulate matter concentration with aerodynamic diameter <10 μm (PM10) (Pande et al., 2018; Dey and Girolamo 2011; Singh et al., 2017). A zone of accumulated and persisting airborne particulates has especially been recognized over central IGB (Kumar et al., 2018). The long...

The impact of extreme temperature on morbidity and mortality has been well established in many developed countries and some developing countries. With the increasing night time temperature, the gap between maximum and minimum temperature has led to decline in diurnal temperature variability that can have serious consequences on health particularly...

The paper aims to explore the biasness in the RegCM climate model outputs for diverse agro-climatic zones of Uttar Pradesh, India, with emphasis on wheat (Rabi growing season) and rice (Kharif growing season) yields with and without bias correction using quantile mapping approach for the baseline period of 1971–2000. The result shows that RCM highl...

For evaluating the impacts of climate change on crop yields regional climate models (RCMs) are now considered better than general circulation models (GCMs). In order to assess what extent the climate output of RCM-RegCM4.0 is biased, this is analysed by comparing the base line simulated daily weather with the observed weather for the corresponding...

Many scientific studies have shown the impact of extreme temperature in the form of excess mortality, mostly evident during seasonal temperature variations and prolonged periods of high temperatures. The rising concern about global warming and future health need to be addressed well and for that it is imperative to study the present and past effect...

Regional Climate Models (RCMs) providing regional climate are nowadays the most useful tool for impact assessments using crop simulation models, but are often limited by inherited biasness from their parent Global Circulation Models (GCMs) and hamper the true result. Given this paucity, we have evaluated the biases in the RCM-RegCM climate outputs...
