🗞️ Driving the news: A groundbreaking 35-year study has revealed drastic changes in global river flows, with nearly half of the largest rivers experiencing significant declines
Using satellite data and modeling, scientists mapped water flow in all rivers, uncovering unexpected rapid shifts driven by climate change and human activity

🔭 The context: Rivers like the Congo, Yangtze, and Plata have seen reduced flow, while smaller, upstream rivers—often in mountainous areas—show increased flow rates due to accelerated ice and snowmelt
This comprehensive study highlights the first global mapping of daily river flows, offering insights beyond the localized snapshots of past research

🌍 Why it matters for the planet: Declining water flow in major rivers jeopardizes freshwater supplies, agriculture, and natural flood defenses like river deltas
Meanwhile, increased flow in smaller rivers raises flooding risks and disrupts ecosystems, demonstrating how climate change and human actions are unbalancing Earth's water system

⏭️ What's next: Researchers aim to pinpoint the exact causes of these changes and devise responses, including reducing fossil fuel use, adapting to altered water cycles, and reevaluating hydropower and floodplain developments
Immediate action is critical to safeguard water resources and mitigate further damage

💬 One quote: “Rivers are dynamic and beautiful beasts… humans should never take them for granted or squander the resources they provide us with.” – Hannah Cloke, hydrology professor, University of Reading

📈 One stat: 44% of the largest rivers experienced annual water flow declines, while small upstream rivers saw a 42% increase in large floods over 35 years.
