(i) Altered precipitation patterns: A warmer atmosphere holds greater moisture, intensifying extreme rainfall events and floods in regions like the Indian monsoon belt while aggravating prolonged droughts elsewhere. (ii) Cryosphere and ocean disruptions: Accelerated melting of Himalayan glaciers increases river runoff initially but causes long-term water shortages, while accelerated polar melting raises sea levels, threatening coastal cities.
