The world is facing an escalating water crisis as climate extremes intensify, with floods, storms, and glacial loss occurring at increasingly abnormal rates.
This is according to the State of Global Water Resources 2024 report released by the World Meteorological Organisation (WMO).
The UN agency describes a planet under mounting pressure from water-related disasters, driven by rising global temperatures and erratic weather patterns.
The report documents events ranging from flash floods in Europe to monsoon devastation in South Asia, warning that such occurrences are becoming more frequent and severe.
Rising Temperatures and Alarming Data
“This year has been marked by relentless water-related hazards,” said Celeste Saulo, WMO Secretary-General. “We’ve seen catastrophic flooding in Pakistan, South Sudan, and Indonesia — and the trend shows no signs of slowing.”
According to the WMO, 2024 was the hottest year in 175 years of recorded observation, with global surface temperatures averaging 1.55°C above pre-industrial levels.
This warming has triggered widespread hydrological disruptions, including the loss of 450 gigatonnes of glacial ice — enough to raise global sea levels by 1.2 millimetres, posing a serious threat to coastal populations.
In central and eastern Europe, Storm Boris caused flash floods that displaced tens of thousands. In the Czech Republic, rivers surged to levels typically expected only once every century.
“The water cycle is no longer predictable,” said Stefan Uhlenbrook, WMO Director of Hydrology. “What used to be rare is becoming routine.”
Regional Impacts and Global Interconnectedness
The report highlights wetter-than-average conditions in central-western Africa, Lake Chad, Kazakhstan, southern Russia, and parts of Asia, while regions such as South America and southern Africa experienced severe droughts.
These extremes underscore the interconnected nature of the global water cycle, where disruptions in one region can have ripple effects across borders.
Beyond the immediate disasters, the WMO warns of a critical gap in water data. Key indicators such as streamflow, groundwater levels, and soil moisture remain under-monitored, limiting the ability of governments and agencies to manage resources and respond to emergencies.
“Without reliable data, we’re flying blind,” Saulo said. “We must invest in monitoring systems and international cooperation to safeguard water security.”
Mitigation and Preparedness
To address the crisis, experts recommend a coordinated global response focused on expanding real-time monitoring of water systems, including streamflow, groundwater, and water quality; Investing in satellite-based hydrological models and open data platforms to improve forecasting and early warning systems.
They also call for upgrading infrastructure such as flood defenses, irrigation systems, and urban drainage networks to withstand increasingly frequent extreme events; training of local authorities and communities in disaster preparedness, water conservation, and climate adaptation, ensuring equitable access to water, especially for vulnerable populations in drought-prone and flood-risk areas, coordinating water governance across sectors including energy, health, agriculture, and urban planning, as well as reducing greenhouse gas emissions to limit further warming and hydrological disruption.
A Call for Global Action
As the world faces the intensifying demands of climate-triggered water disasters, the WMO calls for swift and unified action.
With glaciers vanishing, river basins destabilising, and rainfall patterns shifting, the report calls for a comprehensive global strategy to protect lives, ecosystems, and economies from the deepening crisis.
