The disruptions to the water cycle pose significant risks to ecosystems, agriculture, and human populations. Rivers, vital for trade, water supply, and energy production, are increasingly unreliable. Melting glaciers threaten water security for two billion people and contribute to rising sea levels. The report also highlights the growing frequency of extreme weather events, such as catastrophic floods in Texas and Southeast Asia, and severe droughts in Eastern Europe and the Middle East. These changes exacerbate water scarcity, increase the risk of natural disasters, and threaten biodiversity and ecosystem stability.
