The Human Cost of Water Scarcity BY 2030, WATER DEMAND MAY EXCEED SUPPLY BY 40%, WHILE CLIMATE CHANGE IS EXACERBATING THE SITUATION HEALTH IMPACTS The consumption of dirty water causes cholera, typhoid, and diarrhea. Over 53,000 deaths annually are linked to water-borne diseases. ECONOMIC IMPACTS In developing countries, women and children walk hours daily to fetch water. This time could be used for education, income-generating work, or care-giving. ENVIRONMENTAL IMPACTS Rivers and lakes are drying up, and wetland ecosystems are being lost, reducing biodiversity. SOCIAL IMPACTS Water scarcity causes the large movement of people from countryside to cities. Potentially, it could cause, or increase, conflict between communities or nations.

💦 International cooperation is critical, as over 60% of the world’s #freshwater comes from rivers shared by multiple countries. If nations act unilaterally, water extraction could intensify and lead to greater instability worldwide.

Causes of the Global Water Crisis WATER SCARCITY IS DRIVEN BY A MIX OF ENVIRONMENTAL, ECONOMIC, AND SOCIAL FACTORS. THE KEY CONTRIBUTORS INCLUDE: 1. Climate Change Global warming is changing weather patterns, bringing longer droughts and more severe floods. Melting glaciers and shrinking rivers are reducing freshwater supplies. For example, Lake Chad has shrunk by about 90% due to drought — destabilizing crops and livelihoods across multiple countries — and Himalayan glaciers are retreating rapidly, threatening water for nearly two billion people downstream. 2. Poor Water Infrastructure Many low-income and rural communities lack basic water infrastructure for storage and treatment. In Pakistan, some villages still depend on open ponds shared with animals. Each year, about four trillion cubic meters of freshwater are wasted due to evaporation, leaks, and inefficient irrigation.

3. Overuse of Groundwater Using too much groundwater for farming and industry is causing underground water sources to dry up. When water is pumped out faster than nature can replace it, water levels drop permanently, making groundwater harder or impossible to access in the future. 4. Pollution of Water Resources Contamination of rivers, lakes, and aquifers with industrial waste, pesticides, and sewage has made once-reliable water sources unsafe for consumption. 5. Population Growth The global population is projected to reach 8.5 billion by 2030, increasing demand for water for domestic, agricultural, and industrial use. Rapid urbanization compounds the issue by replacing permeable land with concrete, reducing groundwater recharge by as much as 80% and increasing flash floods instead of sustainable storage.

💦 We're not truly running out of #water, but we're mismanaging the limited supply we can access. Plus, #ClimateChange disrupts natural cycles faster than governments can respond.

Urgent investment is needed to prevent #DayZero scenarios for billions of people.

Data centres are critical infrastructure powering the modern digital economy. With the right policy settings and renewable generation, Australia can position itself as a leader in clean digital infrastructure - creating jobs, improving grid resilience, and driving innovation across the energy system. Julia Hinwood Head of Infrastructure, CEFC

Just so its clear: data centres are not "critical infrastructure".

They are Mystery Factories that can perform inscrutable computation for any digital output, from crypto scams to child abuse material to hospital databases. The broad label just becomes a wide door for harm to run through.

@irishrainforest.bsky.social has shown that trees are much better at planting trees than humans ever will be - the only exception when humans are needed to plant trees is in situations where the indigenous trees are no longer present to plant themselves

Imagine humans asking trees to deliver babies

Very worth reading. I have to say that I didn't have enough space in my post to mention that I reject the carbon credit thing ~97% (global north using global south land=meh). For me, planting trees definitely also means natural succession, although we need to be ready to trial and error much more.

Global Water Distribution AVAILABLE FRESHWATER IS LIMITED AND UNEQUALLY DISTRIBUTED [Charts showing] EARTH’S WATER Saline (Oceans) 97% Freshwater 3% FRESHWATER Icecaps and Glaciers 68.7% Groundwater 30,1% Surface water 0,3% Other 0,9% FRESH, LIQUID SURFACE WATER Lakes 87% Swamps 11% Rivers 2%

💦 Only a small portion of the world’s #water is usable for drinking. To meet our basic needs for drinking, cooking, & hygiene, each of us needs at least 20L of safe freshwater per day.

Currently, 2.2 billion people lack access to safely managed drinking water.

Global Water Scarcity A GRAVE THREAT TO HUMAN SURVIVAL, ECONOMIC DEVELOPMENT, AND ENVIRONMENTAL STABILITY Over two billion people worldwide cannot access clean water. Almost two thirds of the global population (4 B people) find water scarce for at least one month per year. 4.5 billion people have inadequate water sanitation, exposing them to diseases, such as cholera and typhoid fever, and other water-borne illnesses. Agriculture uses 70% of the world’s accessible freshwater, but some 60% of this is wasted due to leaky irrigation systems, inefficient application methods as well as the cultivation of unsuitable crops. About 50% of the world’s wetlands have been destroyed since 1900. Wetlands support the cultivation of rice, a staple in the diet of half the world’s population; as well as providing water filtration, flood control, and storm protection.

🚰 According to the UN, one in three people worldwide do not have access to safe drinking #water, and by 2030, demand for water could exceed supply by 40%.

This must be part of the conversation around #AI.

We Have Entered “an Era of Global Water Bankruptcy” UNITED NATIONS REPORT WARNS OF IRREVERSIBLE CONSEQUENCES What is “Water Bankruptcy”? Nature provides water income in the form of rain and snow, but the world is spending more than it receives — extracting from its rivers, lakes, wetlands and underground aquifers at a much faster rate than they are replenished, putting us in debt. Climate change-fueled heat and drought are compounding the problem. • 50% of the planet’s large lakes have lost water since 1990 • 70% of major aquifers are in long-term decline • An area of wetlands almost the size of the EU has been erased over the past 50 years • Glaciers have shrunk 30% since 1970 • Even in places where water systems are less strained, pollution is reducing the amount of clean drinking water

Stop the Grindadráp Slaughter CALL TO ACTION: NOW IS THE MOMENT TO CONTACT YOUR MEP! MEPs are currently intensifying pressure on the EU Commission to take action against the annual Faroese whale slaughter, due to record-breaking kill numbers. The Faroe Islands enjoy preferen- tial trade arrangements with the EU, as well as access to EU pro- grammes, and security guarantees. However, they are not subject to EU law. MEPs have called for: • Country-of-origin labeling to enable consumer boycotts of Faroese fish products; • Revisions to fisheries agreements to include suspension clauses if the killing continues; • Increased pressure on Denmark, and an investigation into reports that Danish police and military have supported hunt activities and restricted NGO monitoring.

🐋 Please contact your #MEP to support ending the #Grindadráp annual slaughter.

Ongoing hunts completely undermine the EU’s international credibility on #MarineConservation.

At the least, give us the means to boycott Faroese products.

Make your voice heard!

Warming Oceans Mean... THE AVERAGE DAILY GLOBAL SEA SURFACE TEMPERATURE HAS REACHED 20.98º C. THE IMPACTS OF THIS INCLUDE: MORE CO2 Warmer waters have less ability to absorb carbon dioxide, meaning more planet- warming gas will stay in the atmosphere. MELTING GLACIERS Warmer waters will accelerate the melting of glaciers and ice sheets, which flow into the ocean, leading to sea level rise. FORCED MIGRATION Hotter oceans and heat- waves disturb marine species, causing them to move in search of cooler waters, destabilizing ecosystems and coastal economies. CORAL BLEACHING Between 2014–2017 around 75% of the world’s tropical coral reefs experienced heat-stress. For 30% of the world’s reefs, that heat-stress was enough to kill coral.

🌎 The oceans temperatures are steadily rising, with dire implications for our planet.

Our oceans produce half the Earth’s oxygen and drive weather patterns.

We will see more hurricanes and tropical storms, but the worst impacts of warmer oceans happen beneath the sea.

The North Atlantic Current is Slowing Down RESEARCH ON OCEAN VENTILATION SHOWS “AGING” WATER MASS Ocean ventilation occurs when surface water sinks, transporting oxygen and carbon to greater depths. (Simultaneously, colder water wells-up bringing nutrients to the surface.) The efficiency of this process can be tested by “water age” — ie. the time elapsed since a water mass was last in contact with the atmosphere. A new study has found that North Atlantic waters are aging overall. The process of renewal, and circulation, has significantly slowed over the last 30 years. [Graphic showing Atlantic currents]

🌎 “The combination of observations and models provides a consistent picture: North Atlantic waters are aging – and this is in line with the expected weakening of North Atlantic circulation as a consequence of #GlobalWarming.”

"every analyzed heatwave [in a set of 213] have become more intense and more likely due to climate change. The heatwaves over 2000-2009 have become 20 times more likely compared to pre-industrial levels, but over 2010-2019, this influence rises to 200 times."

What is a Seasonal Upwelling? COLD WATER BRINGING NUTRIENTS UP FROM THE DEEP An upwelling occurs when wind pushes warmer surface water away, leading to the colder, deep water being drawn up into its place. An upwelling brings nutrient rich water to the surface — this process is vital for sustaining fisheries and cooling coral reefs. The Gulf of Panama usually has a seasonal upwelling from January to April which fuels productivity across the food chain, but it has failed.

In 2025 the seasonal upwelling in the Gulf of #Panama failed to materialize. The process delivers nutrients that stimulate phytoplankton growth — the foundation of the marine food web.

This is critical for local dynamics and indicates broader changes in ocean systems.

Green vs. Greenwashed HOW TO DIFFERENTIATE REAL GREEN PRODUCTS FROM THE GREENWASHED — CLAIMS SHOULD BE: Evidence-based: If a product claims an environmental benefit, compared with the competition, then the claim should be substantiated. Explained clearly: Packaging and advertising should explain the product’s green claims in plain language and readable type in close proximity to the claim. Accurate: A product’s marketing claim should not overstate, directly or by implication, an environmental attribute or benefit. Specific: An environmental marketing claim should specify whether it refers to the product, the packaging, or just a portion of the product or package.

🌱 #Greenwashing is when companies falsely claim their products are more environmentally sound than they actually are, to capitalize on the demand for eco-friendly products.

Some guidelines on how to differentiate real green products from the greenwashed. ⬇️

How AI Will Revolutionize the Energy Grid: Energy Storage Long-duration energy storage is reaching an important turning point. In 2025 China had several breakthroughs, including activating what is reported to be the world’s first gigawatt-hour vanadium flow battery system, and connecting a hybrid energy storage project combining lithium-ion batteries and supercapacitors. ZH Energy launched the first commercial sulfur-iron flow battery, offering long-duration storage at dramatically lower cost — around 85% less than vanadium-based systems. In 2026, solutions like flow batteries, thermal storage, and next-gen solar cells will become viable at scale. Together, they address one of renewable energy’s biggest challenges: covering the long gaps between periods of generation. This added flexibility will be critical to achieving reliable, round-the-clock Carbon-Free Energy.

⏰ It’s long been the criticism of #RenewableEnergy: what happens when the sun goes in or the wind doesn’t blow?

The answer is simple: 🔋 batteries.

In 2025 we saw real innovation. In 2026, AI optimization will enable the tech to scale up, while prices go down.

How AI Will Revolutionize the Energy Grid: AI Autonomy Artificial intelligence is on track to become the “brain” of the power grid. In 2026, autonomous AI systems are expected to continuously adjust how electricity is produced and delivered to support cleaner energy use. These systems will coordinate devices such as EV chargers and Heating, Ventilation, and Air Conditioning (HVAC), responding in real time to grid conditions. When needed, they can temporarily reduce or shift energy use, keeping supply and demand in balance. AI will also improve grid reliability by using advanced analytics to spot early warning signs in equipment like transformers and power lines — often weeks before something breaks. Problems will be fixed in advance, reducing outages and moving the grid closer to the end-goal: a self-repairing system.

⚡ For the #energy sector, 2026 will be the year of granularity: the precise matching of supply and demand, down to the second and the electron, to ensure more Carbon-Free electricity makes it to end users in real time.
