Abstract

Rising temperatures along with decreasing and irregular rainfall represent a major global concern. This study examines trends in temperature and rainfall across five divisional headquarters of Rajasthan—Bikaner, Jaipur, Jodhpur, Kota, and Udaipur. Historical records of minimum and maximum temperatures, as well as rainfall data spanning 50 years (1970–2020), were obtained from the Climate Research and Services of the India Meteorological Department in Pune. Trend detection and the magnitude of changes were analyzed using the Mann–Kendall (MK) test and Sen’s slope method. The findings reveal a significant upward trend in both minimum and maximum temperatures at all five locations. In contrast, rainfall exhibited a slight but statistically insignificant increase in Kota and Udaipur, while Bikaner, Jaipur, and Jodhpur showed a declining trend.
