Discuss the impact of climate change on the hydrological cycle and the resulting geographic variations in water availability.

Climate change affects the hydrological cycle by altering precipitation patterns, increasing evaporation rates, and shifting the distribution and intensity of storms. These changes lead to geographic variations in water availability, with some regions experiencing increased flooding while others face more severe droughts. These variations impact agriculture, water supply, and ecosystem health, leading to challenges in water management, food security, and socio-economic stability.
