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. theguardian.com/world/2025/jan

@koen_hufkens @biodiversity from the abstract “.. mean transit times of water through aboveground vegetation vary from ~5 days in croplands to ~18 days in evergreen needleleaf forests, with a global median of 8.1 days. In herbaceous..land-cover types with comparatively low water storage &high seasonal water use, such as grasslands, the water stored in biomass may be.. transiting in less than one day. .. plants store little water compared to other pools..”

"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."

@rbreich
It is actually a good demonstration of #TrickleDown – if we remember that the popular concept is completely upside-down!
The #MoneyCycle is very similar to the #WaterCycle: Rain on the highlands feeds millions of tiny streams (low incomes) that *Trickle Down* & feed the crops, populations, towns & cities & the #economy generally, while excess water fills rivers & finally flows into the oceans (the 0.01%).
Rain on the oceans (Top-rate #TaxCuts, bailouts,+++) feeds none of the above.
