The United Nations issues a warning that the world’s water cycle is becoming increasingly unpredictable, with impacts ranging from droughts to flooding. It says rivers, glaciers and groundwater systems are facing worsening disruption, increasing the risk of both water scarcity and excess water in different regions.
The UN’s assessment links part of the volatility to climate drivers, including an unprecedented or strengthening El Niño expected to intensify conditions that can produce prolonged dry spells in some places and heavy rainfall in others. Multiple outlets describe the pattern as an erratic swing between too little and too much water, rather than a return to normal seasonal behavior.
While the sources agree on the overall message—greater unpredictability and heightened risk during the El Niño period—they focus on different aspects. One outlet emphasizes specific affected components such as rivers, glaciers and groundwater, while another highlights the overall “erratic” character of the global water cycle and frames El Niño as an amplifier of a longer-term trend.
