Mountains and Glaciers: Water towers
UN World Water Development Report

Mountain waters are essential to humans and ecosystems

The 2025 edition of the #UnitedNations World Water Development Report highlights the importance of #mountain waters, including alpine #glaciers, which are vital for meeting basic human needs such as water supply and sanitation. They are also essential to ensuring #food and #energy security to billions of people living in and around mountain regions and areas downstream. They also support economic growth through various water-reliant industries. As the ‘water towers’ of the world, mountains are an essential source of fresh #water. They store water in the form of #ice and #snow during cold seasons, releasing it during warmer seasons as a major source of fresh water for users downstream. Mountains play a unique and critical role in the global #WaterCycle, and they affect atmospheric circulation, which drives #weather and #precipitation patterns.

#ClimateCrisis ‘wreaking havoc’ on #Earth’s #watercycle
#GlobalHeating is supercharging storms, #floods and #droughts, affecting entire ecosystems and billions of people
Rising temperatures, caused by burning #fossilfuels, disrupt #water cycle. Warmer air holds more water vapour, leading to more intense downpours. Warmer seas provide more energy to hurricanes and typhoons. #ClimateChange also increases drought by causing more evaporation from soil, and shifting rainfall. https://www.theguardian.com/world/2025/jan/06/climate-crisis-wreaking-havoc-on-earths-water-cycle-report-finds

"Rising temperatures are changing the way #water moves around our planet, wreaking havoc on the #WaterCycle."

This leads to both ferocious #floods and devastating #droughts.

"The real question isn’t if we should do something about it — it’s how quickly we still can."
