From #Himalaya to #Arctic - #GlaciersAtRisk: A Wake-Up Call on #WorldWaterDay

Story by Namrata Dadwal, March 21, 2025

"This year on World Water Day on March 22, the UN is highlighting '#GlacierPreservation'. Why? Because these frozen reservoirs that supply freshwater to nearly two billion people are disappearing at an alarming rate due to #ClimateChange.

"According to the #Copernicus Climate Change Service (#C3S), Earth's #glaciers have lost over 8,200 gigatonnes of ice since 1976, leading to #RisingSeaLevels and #WaterScarcity concerns. Nearly 6,000 gigatonnes were lost between 2000 and 2023, with the 2010s being the worst decade on record for glaciers almost the annual ice loss was more than double that of the 1980s, with an average of 370 gigatonnes of ice vanishing each year."

#WaterScarcity on the Rise: #Rivers Drying at Record Rates

by Vivek SainiVivek Saini, October 8, 2024

"Rivers worldwide are drying up at the fastest rate in 30 years, posing a critical threat to ecosystems, agriculture, and human populations. In 2023, unprecedented heatwaves, prolonged droughts, and erratic rainfall patterns resulted in the most severe year of water depletion in three decades, according to World Meteorological Organization (WMO) reports. This alarming phenomenon is a direct consequence of climate change, worsened by unsustainable human activities, raising the spectre of widespread water scarcity.

A Crisis Accelerating: Rivers Drying at Record Rates

"The world’s rivers, crucial lifelines for billions of people, have shown alarming signs of depletion, with some drying up completely. The WMO’s recent State of the Global Climate report revealed that rivers in Europe, South America, Africa, and Asia experienced their lowest levels since the early 1990s. Rivers like the #Yangtze, #AmazonRiver, and #Danube can no longer support the #ecosystems and communities that depend on them for agriculture, drinking water, and transport.

"The impact of climate change, marked by rising global temperatures, has played a significant role in this crisis. The warming of the Earth’s surface increases the evaporation rate from rivers, lakes, and reservoirs, intensifying water loss. Regions already prone to droughts, such as the Middle East, parts of Africa, and southern Europe, face even more severe shortages due to intensified drought cycles. In 2023 alone, the Danube, Europe’s second-longest river, saw record-low water levels, which crippled shipping routes and threatened agricultural output in countries like #Hungary and #Romania.

"This drying trend is not limited to one region. The #ColoradoRiver continues to shrink in the United States, causing severe #WaterShortages for millions in states like #Arizona and #Nevada. Similar trends have been observed in the #IndusRiver in #SouthAsia, which supports millions of people in #Pakistan and #India. These drying rivers are a wake-up call for the global community to address water conservation and management issues before irreversible damage occurs​."

The consensus of experts was that the combination of the winds, unseasonably dry conditions & multiple fires breaking out one another in the same geographic region made widespread destruction inevitable.

The article highlights many valid points, but the bottom line is that there was nothing that could’ve stopped the devastating tragedy. The destruction, suffering, & death toll continue to rise.

Pour celles et ceux que ça intéressent, les incendies en Californie cette semaine m'ont rappelé les remarques d'Elisabeth Anker dans son excellent livre, Ugly Freedom, sur l'accaparement de l'eau et les justifications de cet accaparement par les résidents (richissimes) de Rancho Santa Fe.

On lira un long passage traduit ici :

outsiderland.com/danahilliot/n

Et un extrait ci-dessous :

"Les habitants de Rancho Santa Fe peuvent sembler excessivement égoïstes, motivés uniquement par l’irresponsabilité et la cupidité, mais l’enjeu est bien plus important que la psychologie personnelle. L’accent mis sur la psychologie occulte la vision du monde plus large et partagée qui influence leurs actions. Une histoire de liberté populaire et largement appréciée sous-tend toutes leurs revendications et leur confère une lisibilité politique. Pour les habitants de Rancho Santa Fe, l’utilisation de l’eau est une forme de liberté qui implique le choix individuel de consommer des ressources naturelles que l’on paie. La liberté consiste à extraire des biens précieux du patrimoine commun sans se soucier des autres ; c’est la capacité de payer, et non le bien collectif, qui détermine la liberté d’action. Dans cette version de la liberté, les frontières territoriales délimitent la pratique de la liberté : les frontières souveraines, à la fois du soi et de la propriété – des espaces privés et autodéterminés sur lesquels on a autorité – fixent la limite de la liberté. La liberté est enfermée dans un moi individuel et une propriété personnelle, barricadée contre les autres dans une affirmation de séparation. La responsabilité s’étend aux quatre acres de la propriété privée, mais pas au-delà, qui semble séparable des lacs bas et des collines desséchées immédiatement adjacents."

Dans le même ordre d'idées, on lira une réflexion passionnante de la philosophe marxiste Amy E. Wendling, dans The Ruling Ideas. Bourgeois Political Concepts (2011) sur la question de savoir si l'eau (ou le corps humain) peuvent être l'objet de la propriété. Elle prend notamment l'exemple de l'appropriation privée des grandes nappes d'eau phréatiques (Ogallala Aquifer) du Midwest par des businessmen du Texas (et les conséquences qui s'ensuivent, notamment en terme de pénurie, dans les régions et États voisins). Elle cite notamment un article de Charles Laurences concernant le sinistre businessman texan [T. Boone] Pickens :

telegraph.co.uk/earth/8359076/"

« À l'exception du Texas, tous les États situés au-dessus de l'aquifère d'Ogallala exercent un certain contrôle gouvernemental sur l'utilisation de l'eau]. Le Texas autorise, au contraire, des droits illimités à la propriété privée de l'eau. Charles Laurence écrit

"Mais le Texas, fidèle à son style conscient d'« individualisme sauvage », n'a pas de tels contrôles juridiques. Il maintient ses lois de l'époque du Far West sur le « droit de capture ». Cela signifie que si vous avez de l'eau sous votre terre, ou une rivière qui la traverse, vous pouvez en prendre et en utiliser autant que vous le souhaitez. Vous pouvez arroser le maïs ou les vaches, ou vous pouvez gagner de l'argent en vendant l'eau à la banlieue assoiffée la plus proche. Si vous voulez transformer votre terre en désert, vous pouvez le faire."

La partie de l'Ogallala située sous le Texas en a souffert, tout comme les communautés agricoles qui en dépendent. Mais il ne s'agit pas seulement d'un problème d'action collective auquel sont confrontés les propriétaires terriens, qui, selon Laurence, ont réduit le forage de puits et modifié d'autres pratiques d'utilisation de l'eau en reconnaissant clairement la dimension collective du problème. Au lieu de cela, Pickens prévoit de commercialiser l'eau en l'acheminant vers une grande zone urbaine géographiquement éloignée.

While Trump & Republicans deny the climate crisis, disasters remind Americans why the US government should be mitigating climate change. Republicans aren’t just ignoring CC, their agenda includes rewarding more fossil fuel drilling, which will increase GHG emissions, removing safeguards & regulations that Pres Biden put in place, & possibly defunding FEMA.

CA farmers could soon enjoy bumper crops thanks to Trump’s pledge to lift water restrictions. But who'll pick them if he follows thru on his deportation threats?

The country’s largest AG constituency backed Trump re his promises to “open the faucet” & deliver more water to the C Valley. Now it’s reckoning with an uncomfortable contradiction: he also campaigned on mass deportations of undoc. #immigrants *at least half of CA's AG workforce.

Freshwater is scarce, worldwide.

"An international team of scientists using observations from NASA-German satellites found evidence that Earth's total amount of freshwater dropped abruptly starting in May 2014 and has remained low ever since. Reporting in Surveys in Geophysics, the researchers suggested the shift could indicate Earth's continents have entered a persistently drier phase."

The system that moves #water around the #Earth is off balance for the first time in human history

The #WaterCycle refers to the complex system by which water moves around the Earth.

By Laura Paddison, CNN
Published Oct 17, 2024

"Humanity has thrown the global water cycle off balance 'for the first time in human history,' fueling a growing water disaster that will wreak havoc on economies, #FoodProduction and lives, according to a landmark new report.

"Decades of destructive #LandUse and #WaterMismanagement have collided with the human-caused #ClimateCrisis to put 'unprecedented stress' on the global water cycle, said the report published Wednesday by the Global Commission on the Economics of Water, a group of international leaders and experts.

"The water cycle refers to the complex system by which water moves around the Earth. Water evaporates from the ground — including from lakes, rivers and plants — and rises into the atmosphere, forming large rivers of water vapor able to travel long distances, before cooling, condensing and eventually falling back to the ground as rain or snow.

"Disruptions to the water cycle are already causing suffering. Nearly 3 billion people face #WaterScarcity. #Crops are shriveling and cities are sinking as the groundwater beneath them dries out.

"The consequences will be even more catastrophic without urgent action. The water crisis threatens more than 50% of global food production and risks shaving an average of 8% off countries’ GDPs by 2050, with much higher losses of up to 15% projected in low-income countries, the report found.

'“For the first time in human history, we are pushing the global water cycle out of balance,' said Johan Rockström, co-chair of the Global Commission on the Economics of Water and a report author. '#Precipitation, the source of all #freshwater, can no longer be relied upon.'

"The report differentiates between '#BlueWater,' the liquid water in #lakes, #rivers and #aquifers, and '#GreenWater,' the moisture stored in #soils and #plants.

"While the supply of green water has long been overlooked, it is just as important to the water cycle, the report says, as it returns to the atmosphere when plants release water vapor, generating about half of all rainfall over land.

"Disruptions to the water cycle are 'deeply intertwined' with climate change, the report found.

"A stable supply of green water is vital for supporting vegetation that can store planet-heating #carbon. But the damage humans inflict, including destroying #wetlands and tearing down #forests, is depleting these carbon sinks and accelerating #GlobalWarming. In turn, climate change-fueled heat is drying out landscapes, reducing moisture and increasing [#wildfire] risk.

"The crisis is made more urgent by the huge need for water. The report calculates that, on average, people need a minimum of about 4,000 liters (just over 1,000 gallons) a day to lead a 'dignified life,' far above the 50 to 100 liters the United Nations says is needed for basic needs, and more than most regions will be able to provide from local sources.

"Richard Allan, a climate science professor at Reading University, England, said the report 'paints a grim picture of human-caused disruption to the global water cycle, the most precious natural resource that ultimately sustains our livelihoods.'

"Human activities 'are altering the fabric of our land and the air above which is warming the climate, intensifying both wet and dry extremes, and sending wind and rainfall patterns out of kilter,' added Allan, who was not involved in the report.

"The crisis can only be addressed through better management of natural resources and massive cuts in planet-heating pollution, he told CNN.
"The report’s authors say world governments must recognize the water cycle as a '#CommonGood' and address it collectively. Countries are dependent on each other, not only through lakes and rivers that span borders, but also because of water in the atmosphere, which can travel huge distances — meaning decisions made in one country can disrupt rainfall in another.

"The report calls for a 'fundamental regearing of where water sits in economies,' including better pricing to discourage wastefulness and the tendency to plant water-thirsty crops and facilities, such as #DataCenters, in water-stressed regions."

#AI #GenerativeAI #DataCenters #Water #WaterScarcity: "The building of new data centres is increasing demand for water resources. Some data centres are presently located in areas of water stress or are likely to be in the future. Developing cooling technologies which minimise or do not require water is becoming increasingly important. Perhaps AI will find a scalable solution to this problem."

Due to climate change, population growth, and increased demand, water scarcity is expected to escalate significantly over the next few decades. Regions already experiencing water stress will face more severe shortages, impacting agriculture, industry, and daily life.

Deeply concerning, global warming is responsible for crises around the world:

Mexico City is home to nearly 22M people. But for months, the sprawling city has been suffering from diminishing water supplies — and now, one of the world's most populated cities is on the verge of a "day zero" where it will no longer have enough water to provide residents.

#ClimateChange exacerbates extreme weather events and #WaterScarcity, leading to conflicts over dwindling water resources.

Despite this, the construction of dams continues, driven by the belief that #hydropower can mitigate climate change.

Dams emit significant greenhouse gases and are vulnerable to climate impacts. Tensions rise over projects like the Grand Ethiopian Renaissance Dam, with China's involvement adding to the struggle for resource control.
