The world’s rivers are facing an unprecedented drought, with water levels declining at an alarming rate due to climate change. According to a recent report by the World Meteorological Organization (WMO), river levels have plummeted over the past five years, reaching a record low in 2023.
More than half of all river watersheds experienced abnormal conditions in 2023, with most operating at a deficit. This coincides with the hottest year on record and extreme weather events, highlighting the clear connection between climate change and low water level in rivers.
Celeste Saulo, Secretary-General of the WMO, emphasizes the urgency of the situation, stating that water is a crucial indicator of climate change. The increasing frequency and intensity of extreme rainfall, floods, and droughts have severe consequences for lives, ecosystems, and economies.
Rising temperatures have accelerated the Earth’s natural water cycle, making it more erratic and unpredictable. This results in both water shortages and excessive rainfall, posing significant challenges.
The transition from La Niña to El Niño, two opposing climate patterns, is further exacerbating the issue. While these cycles have occurred for centuries, climate change is intensifying their effects, making them more difficult to predict.
The Amazon river basin experienced its lowest water levels since 1902 last year, primarily due to the shift from La Niña to El Niño and widespread ocean warming. The WMO report’s data, although from 2023, remains relevant in light of recent events like Hurricane Helene, which caused devastating flooding and loss of life.
In conclusion, the report presents a concerning picture of the future of riversheds worldwide if climate change continues unchecked. Urgent action is necessary to address this crisis and protect our water resources.
