On the eve of the UN Climate Change negotiations in Glasgow, COP26, the heads of ten international organizations issued today a united and urgent call to governments to prioritize integrated water and climate action given the all-pervasive impacts on sustainable development.
“This letter also appeals for urgent and accelerated action to address the water-related consequences of climate change,” said World Meteorological Organisation (WMO) spokesperson Clare Nullis at a media briefing in Geneva.
The letter urges governments to address more effectively the water dimensions of climate change adaptation and mitigation, as provided for in a UN-agreed framework to accelerate progress towards Sustainable Development Goal 6 (ensure availability and sustainable management of water and sanitation for all).
It was signed by the heads of WMO, the Food and Agriculture Organization of the United Nations (FAO), the UN Educational, Scientific and Cultural Organization (UNESCO), the World Health Organization (WHO), the International Fund for Agricultural Development (IFAD), the UN Environment Programme (UNEP), the UN Children’s Fund (UNICEF), the UN University (UNU), the UN Economic Commission for Europe (UNECE) and the Global Water Partnership (GWP).
Reading the letter, Ms Nullis said that “climate change is dramatically affecting the water cycle, making droughts and floods more extreme and frequent and decreasing the natural water storage in ice and snow. Rising temperature and variability in flow patterns of water bodies also strongly affect water quality in surface and groundwater.”
“Changing precipitation patterns are already impacting agriculture, food systems, and livelihoods are becoming increasingly vulnerable, as well as ecosystems, and biodiversity. Rising sea levels threaten communities, infrastructure, coastal environments and aquifers,” she continued.
According to a recent UNICEF report on the impact of climate change on children, over one third of the world’s children (920 million) are currently severely exposed to water scarcity.
In addition, the UN World Water development Report 2020 emphasizes that water is the “climate connector”, allowing for greater collaboration and coordination in policy-making across the majority of targets for climate change (Paris Agreement), sustainable development (2030 Agenda and its Sustainable Development Goals ), and disaster risk reduction (Sendai Framework).

New data showing that rivers were at their lowest level for decades last year provides further evidence that the climate crisis is real and countries must act immediately to protect themselves from the increasing threat to communities and livelihoods, the UN World Meteorological Organization (WMO) said on Thursday.
The key findings from WMO’s State of Global Water Resources 2025 report covering the hydrological cycle and extreme events in the five-year period to last year:
Highlighting the long-term decline in the Earth’s freshwater storage and glacier melt, WMO Secretary-General Celeste Saulo explained that the planet’s water reserves used to act as a planetary “savings account” that absorbed the occasional dry season, avoiding a water crisis. “One of the central stories of the 2025 report is what is happening to that savings account? And the simple answer is that we are depleting it,” she told journalists in Geneva.
Groundwater reserves are equally stretched and have been in decline since 2014, WMO’s report states, with nearly two-thirds of monitored wells worldwide showing levels lower than the historical norm and indicating a shift “further toward deficit…not recovery”.
“At the same time, we are seeing more water-related disasters,” Ms. Saulo said, while also stressing that the currently strengthening El Niño “will increase the risk of drought in some areas, and flooding in others”.
Glaciers disappearing
In 2025, for the fourth consecutive year, every major glaciated region on Earth lost ice mass, leading to short-term hazards including floods and long-term water insecurity, according to WMO.
Responding to a question about whether the changing global water cycle might have contributed to the deadly Nepal-China flooding disaster, Ms. Saulo explained that melting ice and rock was just one factor in the chain of events that ultimately sent a massive and deadly wall of water and debris downstream on 26 August, killing at least 1,367 people.
“You asked if it could happen again? Absolutely; the problem in this region is that there’s 63,700 glaciers at the last count,” she told a Press Conference in Geneva. “Even if you’re looking with remote sensing with satellites at these glaciers, you might see some faults, you might see some slight shifting, that does not mean necessarily catastrophic collapse. So, in order to plan for this, it’s very, very difficult. But the international community is looking very hard at ways in which we can bring people together to solve some of these monitoring issues.”
Data indicates that glaciers shrank between 2023 and 2025 with cumulative losses of 1,400 gigatonnes of water – or about one third of annual fresh water needs.
Every major glacier region on Earth lost ice for the fourth consecutive year.
“All 19 glacier regions around the globe lost ice; in Central Asia, Iceland, the Russian Arctic and western Canada and the United States, it was among the three worst years on record,” said Wayne Jenkinson, WMO’s Director of Hydrology and Cryosphere.
Some regions with smaller glaciers such as Central Europe, the Caucasus, the western Canada and the United States may already have reached “peak water”, Mr. Jenkinson warned.
“After this point, the glacier gives less meltwater each year simply because there is less ice left to melt. That matters for every community downstream that relies on water during hot, dry summers,” he explained.
Narelle van der Wel, WMO’s Head of Cryosphere Monitoring, Predictions and Services, stressed that while some further glacier loss is unavoidable, the eventual scale of the decline is not predetermined.
“Some glacier loss is inevitable, but total loss of glaciers is not yet inevitable,” she said, pointing to emissions reductions as central to limiting future losses.
Preparing for moving baselines
The report does not attribute every observed change to climate change alone. WMO says pressure on water resources and natural variability also contribute.
Mr. Jenkinson said governments need to prepare for “moving baselines” as historical patterns become less reliable.
“The situation 30 years ago is not where we are today,” he said. Countries, he added, need to prepare “for those changes that have really already arrived”.
