“…Over the past few decades, three nearby islands have sunk, and the largest island, Sagar, is progressively sinking as well. This has led to a high number of environmental migrants (Bera et al, 2021;Mandal et al, 2019). The negative effects of such occurrences include the loss of land, decreased agricultural output, inundation of low-lying coastal areas, and departure of individuals looking for work in metropolitan enclaves.…”

Climate change has been a major existential threat to humanity, and much-debated predictions of its devastating consequences are becoming a reality. The various natural hazards and disasters are a cause of grave concern, and there is a need to study these hazards, their impact on the society, the nation’s economy, and various other vulnerabilities in the future. There is a huge gap in understanding the impact of climate change on the society, and it seems that we all are living in a state of denial. So, there is a strong need to combine all available data in one document to give a holistic view of actual problem. Therefore, this paper, will review the various likely vulnerabilities in front of India and how climate change will exacerbate the Natural hazards. It will also bring out the likely impacts of climate change on the India’s economy.Moreover, it’s evident from this review that India’s vulnerability to climate change and consequential hazards is greatly amplified because of its socioeconomic, demographic, and geographic characteristics and large population, which strain the existing infrastructure. Various findings based on review of data is also listed at the end to give the consolidated outcomings of the review, which highlight the major threats as heat waves, erratic precipitation, cyclones and floods. The paper will also highlight how developing countries like India are spearheading the drive to decrease the carbon footprint and prevent further impacts on the climate.

“…Climate change as a result of global warming shows its effect on many hydrometeorological parameters. As a result of the changes in hydrometeorological parameters, there is an increase in events such as the rise of sea level due to the melting of glaciers, the occurrence of hurricanes, floods, and droughts in many parts of the world as a result of sudden temperature changes, and the increase in forest fires [1][2]. These global effects of climate change include regional differences [3][4].…”

Türkiye, which has a complex climate structure, is shown among the countries that will be most affected by climate change with the effect of global warming. These effects will differ in different regions due to their topographic structure, location, and orographic characteristics. Trend analyzes are used to determine the direction and magnitude of this variability. In this study, trend analysis was carried out by using hydrometeorological data obtained from streamflow and meteorology stations located in the Karasu Sub-Basin located in the Euphrates-Tigris Basin. Three innovative trend methods, namely the Şen-Innovative Trend Analysis, Onyutha Trend Test, Combination of Wilcoxon Test and Scatter Diagram trend tests, were used together with the classical Mann-Kendall method in the monthly scale analysis of hydrometeorological data of the 1979-2020 period. Both graphical and statistical trend analysis can be done with innovative methods. The results obtained in the study, in which trend analyses were evaluated at the α=0.05 significance level, reveal significant and insignificant decreasing trends in the parameters of mean streamflow, maximum precipitation, total precipitation, mean and minimum relative humidity. Significant and insignificant increasing trends were determined in the maximum, minimum, and mean temperature, maximum relative humidity, and mean wind speed data. The trends obtained in the methods used in general are consistent with each other. The findings of this study could lead to a better knowledge of the region's hydrology and contribute sustainable water management. The trend analysis methods used in the study are thought to be quite helpful in the analysis of hydro-meteorological time series.

“…Expected effects of changes in global climate include warmer temperatures, rising sea levels, and potentially more frequent and extreme weather events such as hurricanes, tropical cyclones and heat waves. The Sundarbans located in the southern part of West Bengal, India and Bangladesh lies on the delta of Ganges, Brahmaputra and Meghna rivers in the Bay of Bengal falls in one of the most vulnerable zones of abrupt climate change (Mandal , et al 2019a). The Indian Sundarbans are located in the districts of North and South 24 Parganas representing the coastal part of West Bengal.…”

Sundarbans in West Bengal of India by virtue of its strategic location in the Eastern coast on the Bay of Bengal falls in one of the most vulnerable zones of abrupt climate change. Temporal trends of weather parameters of Canning Town (22o18'10.8'' N Latitude, 88o39'58.4'' E Longitude, elevation 3.52 m msl) representing Indian Sundarbans were analysed by non-parametric Mann-Kendall test and Sen's slope approaches. Analysis of long term rainfall data (1966-2015) indicated that Canning receives a mean annual rainfall of 1821 mm (±341.8 mm) with a considerable variation (CV = 18.8%). The results revealed that total annual rainfall trend decreased non-signicantly at the rate of 0.94 mm yr-1. On an average 84.4 rainy days in a year was recorded in the region, whereas during last ten years (2006-2015), the number of rainy days was reduced to 79.7 days yr-1. There was no signicant change in maximum, minimum and mean temperature of the region. Bright sunshine hours declined signicantly at an annual rate of 0.055 hr yr-1. Reference crop evapotranspiration (ET ) calculated using FAO Penman-Monteith method revealed that annual ET signicantly decreased at the rate of 5.98 mm yr-1. There was 2.7 times surplus rainfall than crop evapotranspiration during monsoon months indicating very high scope of water harvesting to tackle water logging during the monsoon season and unavailability of fresh water for irrigation during lean season.
