“…However, the projected increase in minimum temperature toward EC varies from 4.6 • C in Bageshwar to 5.1 • C in Chamoli district for the IPCC AR5 RCP 8.5 scenario. Therefore, the lower line of the temperature, i.e., the minimum temperature, remains relatively stable, and the continuous increase in the upper limit of diurnal temperature represented by maximum temperature is of serious concern [68,69].…”

The climate change scenarios, especially global warming, have raised significant concerns, and the Himalayan regions such as Uttarakhand are highly vulnerable to such climatic shifts. Considering 10 Coordinated Regional Climate Downscaling Experiments in South Asia (CORDEX-SA), experiments with 3 regional climate models (RCMs), driven by 13 global climate models, historical estimates and future projections are analyzed from the mid-century (MC) i.e., from 2021–2050 to the end of the century (EC) i.e., from 2070–2099 to characterize annual and seasonal variations in precipitation and temperature. The analysis shows a decrease in the annual average precipitation by 5.92% at MC and an increase of 5.97% at EC for the Representative Climate Pathway (RCP) 4.5, while precipitation may likely increase from 2.83% to 15.89% towards MC and EC in the RCP 8.5. The maximum temperature may likely increase from 0.42 °C to 3.07 °C from MC to EC in the RCP 4.5 and from 0.83 °C to 5.49 °C in the RCP 8.5. In addition, the minimum temperature may increase from 0.80 °C to 3.25 °C from MC to EC in the RCP 4.5 and from 0.30 °C to 5.86 °C from MC to EC in the RCP 8.5. Notably, a decrease in the pre-monsoon precipitation at EC and a higher increase in the maximum temperature during the monsoon season are observed. An increase in the maximum temperature along with precipitation may lead to an increase in the frequency of the monsoon season’s extreme rainfall events.

“…Northeast India, which is one of the homogeneous regions and has famous for its enormous rainfall, has experienced a signi cant reduction in rainfall after 1950 (Guhathakurta et al, 2015). A study on rainfall over different climatic zones of India based on the distribution of the Köppen climate, reveals that after 1975, region of tropical moist-evergreen rain forest becoming tropical dry land and semiarid-dry climate becoming desert land (Rao et al, 2016). Recently, Ramarao et al (2019) have illustrated that compare to the previous decade, recent decades have experienced 10% expansion of the semiarid region over the Indian main landmass.…”

This study presents the reversal nature in rainfall over heavy rainfall zone (HRZ; more than 80% of the long-period average (LPA) of the Indian summer monsoon rainfall (ISMR)) and low rainfall zone (LRZ; less than 40% of ISMR-LPA) in India. The India Meteorological Department (IMD) high-resolution (0.25˚×0.25˚) dataset is used from 1901 to 2016. The single and multiple change point detection techniques are used to nd the change in rainfall pattern over both the regions. Further, the study period is divided into two halves P1 and P2 in order to study change in rainfall pattern in the recent and past periods. In P2, rainfall pattern gets reversed and interestingly ISMR has shown an increasing trend over LRZ and a decreasing trend is noticed over HRZ and the results are statistically signi cant. The increasing/decreasing number of moderate and high intensity rainfall events are the main cause for this reversal pattern. Additionally, the number of dry days is increased over the HRZ and deceased over the LRZ. This study further con rms that 'dry becomes drier and wet becomes wetter' paradigm is not solely acceptable for India. The present study provides information about changes in dry days and ISMR variability in the context of climate change, which will be useful to agricultural risk management, water resources, drought monitoring, model developers, and policy planer on the adaptation strategies for climate change.

“…The existing scholarly studies prove the gradual increase since the mid-19th century [3] [4] [5] [6] [7]. The regional warming studies also indicate the increasing temperature in particular locations and larger scales that include both natural and built habitats [8] [9] [10] [11]. Hence, many context-specific studies have recorded significant impacts on productivity [12], frequency and intensity of natural disasters [2] [13] [14] [15], the reoccurrence and severity of natural disasters [16], surface warming [17], water shortage [18] [19], societal health [20], etc.…”

While global warming is only one part of climate change effects, it poses the highest risk to our habitats and ecologies. It is alarming that global warming has heightened in multiple locations and is intensified since the early 1970s. Since then, there are certain global warming patterns that could guide us with an overview of what mitigation and adaptation strategies should be developed in the future decades. There are certain regions affected more than another, and there are certain patterns with adverse effects on regions, sub-regions, and even continents. This study provides an insightful analysis of recent global warming patterns, those that are affecting us the most with regional climate change of different types, upsurge in frequency and intensity of natural disasters, and drastic impacts on our ecosystems around the world. By analysing the global warming patterns of these last four decades, this research study sheds light on where these patterns are coming from, how they are developing, and what are their impacts. This study is conducted through grey literature and analysis of the recorded global warming data publicly available by the NASA-GISS data centre for global temperature. This brief-but comprehensive-analysis helps us to have a better understanding of what comes next for global warming impacts, and how we should ultimately react. The study contributes to the field by discovering three key points analysed based on available data and literature on recorded global temperature, including: differences between north and south hemispheres, specific patterns due to ocean surface temperature increase, and recent impacts on particular regions. The study concludes with the importance of global scale analysis to have a more realistic understanding of the global warming patterns and their impacts on all living habitats.
