“…IPCC (2019) indicates that mountain biodiversity are Reason for Concern (RFC) due to expected global warming of 1.5 °C by the twenty-first century. Various studies suggest that warming in the Himalaya has been much greater than global average over last 100 years (Kumar et al, 2006;Shrestha et al, 2019;Krishnan et al, 2020). It has also been reported that temperature in Himalayan region increased by 1.5 °C as compared to an average increase of 0.74 °C globally in last century (Shrestha et al, 2012;Gautam et al, 2013;Krishnan et al, 2020).…”

“…It is widely reported that the global average temperature has risen by around 1 °C since pre-industrial times (Hoegh-Guldberg et al, 2018;Allen et al, 2018). At the current rate of temperature rise, it is likely that global warming will reach 1.5 °C by 2052 and 3-5 °C by the end of the century (Allen et al, 2018;Krishnan et al, 2020). Even if all the 'Nationally Determined Contributions' made under 2015 Paris agreement are met, global warming is projected to exceed 3 °C by the end of this century (Allen et al, 2018).…”

“…Even if all the 'Nationally Determined Contributions' made under 2015 Paris agreement are met, global warming is projected to exceed 3 °C by the end of this century (Allen et al, 2018). India's average temperature has risen by around 0.7 °C during 1901-2018 (Srivastava et al, 2019;Krishnan et al, 2020); the largest increase in the annual mean temperature (0.2 °C per decade) observed in some areas of north India (Krishnan et al, 2020). The mean temperature rise over India by the end of the twenty-first century is projected to be in the range of 2.4-4.4 °C under RCP8.5 scenario (Krishnan et al, 2020).…”

There are a few regions in the world, where climate change impacts are more intense than other regions of the world, and Himalaya is the case. The Himalaya, one of the biodiversity hotspot regions and provider of ecosystem services to billion of people all across the world. Present study reviewed and synthesized climate change studies in the Himalayan region in general and Indian Himalayan region (IHR) in particular. Analysis of the literature indicates exponentially increase in climate change studies 2005 onward in the IHR, and maximum are from Jammu and Kashmir (105) followed by Uttarakhand (100) and Himachal Pradesh (77). Among the subject types, maximum climate change impact was studied on water resources/glacier retreat (141 studies) followed by agriculture (113) and forests/biodiversity (86). Increasing temperature, frequent drought spells, erratic rainfall and declining snowfall are commonly reported indicators of climate change. For instance, temperature is reported to increase by 1.5 °C in the Himalaya than an average increase of 0.74 °C globally in last century; however, it varied in eastern (0.1 °C per decade and western Himalayas (0.09 °C per decade. An increase in temperature between 0.28 and 0.80 °C per decade was reported for North-western Himalaya and 0.20-1.00 °C per decade for Eastern Himalaya. The higher altitude of Himalayan and Trans-Himalayan zone are reported to be warming at higher rates. Many of the glaciers were reported to be retreating in both eastern and western Himalaya. Heavy rainfall is becoming very common in the region often accompanied by cloudbursts that aggravate flood situation many times. Perception-based studies of the region reported to provide firsthand and detailed descriptions of climate change indicators and impacts from rural and remote areas, where no instrumental data are available.

Hot stressful work conditions impose subsequent suppressions on workers' wellbeing resulting in heat-related morbidities, reduced productivity, and economic burden. Heat stress evaluations require costly monitoring tools that may be uneconomical while monitoring multiple locations simultaneously under the targeted workplace, especially in industrially developing countries.

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 radiation (Srad) during 1984–2016 over 14 different agro‐climatic zones (ACZs) in India. The changes in the DTR trend between two time periods:1951–2016 and 1991–2016 (recent period) are also assessed. The results indicate an overall increasing trend in DTR (0.038°C/decade), Tmax (0.078°C/decade, significant), Tmin (0.049°C/decade) during 1951–2016 and Srad (0.10 MJ/m2/day/decade) during 1984–2016. However, a decreasing trend in DTR (−0.02°C/decade) and a significant increasing trend in Tmin (0.210°C/decade) was noted during 1991–2016. The decadal changes showed an evident decline in DTR during the recent period since 1991. The relative increase in Tmin (0.21°C/decade, significant) compared to Tmax (0.18°C/decade) resulted in a decreasing DTR trend. This was evident across the 5 out of the 14 agro‐climatic zones for the 1991–2016 period. The seasonal analysis showed a significant (95%) increasing trend in DTR during pre‐monsoon and monsoon (1951–2016), and a negative trend for the post‐monsoon and monsoon since 1991. There were also interesting spatial differences found with the ACZs in the north‐west, parts of Gangetic plain, north‐east, and central India exhibiting negative DTR trends. The effect of Srad is larger on Tmax than Tmin; therefore, the decrease in Srad in parts of Gangetic plain likely contributed to a smaller increase in Tmax relative to Tmin and led to a decreasing trend in DTR. At the same time, the west coast, east coast, and southern region show positive trends. The observational analysis finds a distinct increase in the Tmin and also highlights the need for future assessments to continue investigate the causes of these spatio‐temporal changes found in this study.
