The Guardian - Climate warning as world’s rivers dry up at fastest rate for 30 years
This recent article from The Guardian reports on the alarming rate at which global rivers are drying up, with 2023 marking the fastest decline in 30 years. The World Meteorological Organization (WMO) released its State of Global Water Resources report, revealing that over 50% of the world’s river catchment areas were in deficit last year. Major rivers such as the Amazon, Mississippi, Ganges, and Mekong hit record-low water levels, threatening water security for millions of people.
The report attributes these extreme conditions to climate breakdown, with 2023 also being the hottest year on record. The shift from La Niña to El Niño mid-year contributed to widespread droughts and devastating floods. In regions like North and South America, Asia, and Oceania, rivers ran dry, while countries such as New Zealand, the Philippines, and parts of Africa faced destructive floods. This dual threat of too much and too little water underscores the volatility of the global water cycle as temperatures rise.
WMO Secretary-General Celeste Saulo warned that water is the "canary in the coalmine of climate change," pointing to the urgent need for action. Rising global temperatures are accelerating the hydrological cycle, resulting in unpredictable rainfall, more frequent droughts, and faster melting of glaciers. Alarmingly, glaciers worldwide lost over 600 gigatonnes of water in 2023, with Switzerland’s Alps losing 10% of their volume in the past two years.
As we navigate the growing complexities of water resource management in an era of climate volatility, ongoing initiatives like the Canada1Water project (C1W) are essential. C1W provides critical data and insights into the impacts of climate change on Canada’s water systems, offering a vital resource for decision-makers seeking to develop sustainable water management strategies and ensure long-term water security for the country.
