Local communities are mounting resistance to the construction of AI data centers in their areas, citing concerns over electricity and water use, noise, and limited local economic benefit. The debate is playing out across multiple regions as companies race to expand computing capacity for artificial intelligence, turning siting decisions into a contested political issue.

California is examining results from projects that place solar panels over irrigation canals, an approach meant to generate clean power while reducing water evaporation. The state is learning how the panels perform in practice and whether covering canals at scale could cut both water loss and emissions, drawing attention to a idea piloted in the Turlock Irrigation District's Project Nexus.

A new report warns that climate change and the rapid growth of artificial intelligence are together placing unprecedented pressure on the world's water systems. Rising temperatures are disrupting rainfall and depleting supplies, while AI data centres consume vast amounts of water for cooling, intensifying competition for a scarce resource.

The European Union is moving to restrict the energy and water consumption of data centres, a sector whose rapid growth driven by cloud computing and artificial intelligence has put mounting pressure on electricity grids and water supplies. The proposal signals tighter regulation of tech infrastructure across member states, with debate focusing on how sustainability rules will affect data centre operators and Europe's digital economy.

California is preparing for flooding and landslides as forecasters expect a strong El Niño this year, a warming of equatorial Pacific waters that disrupts weather worldwide. After years of coastal erosion — with Pacifica, south of San Francisco, already hit — officials warn the storms the pattern typically brings could prove especially damaging to weakened coastlines and hillsides.

A powerful nor'easter is battering the Northeastern United States, causing coastal flooding and leaving more than 130,000 customers without power. High tides are threatening coastal communities as the storm pushes water onshore, with utilities working to restore service. Outlets including AP and Spectrum News are tracking flooding conditions and outage numbers as the storm continues.

NASA's Perseverance rover has uncovered evidence that Jezero Crater on Mars was more complex than previously thought, indicating it was not simply an ancient lake. The finding suggests the crater experienced a richer and more varied geological history, with implications for understanding Mars' past water activity and its potential to have once supported life.

Researchers subjected water to light roughly 10 billion times brighter than sunlight, expecting faster evaporation, but the water did not evaporate any quicker. The surprising null result challenges assumptions about how extremely intense light interacts with liquid water, and is drawing attention from physicists curious about what limits evaporation under such extreme conditions.

Bridgewater argues that the current surge in artificial intelligence capital expenditure can only be justified if enterprise and consumer adoption of AI scales rapidly enough to generate returns. The hedge fund's analysis adds to the debate over whether massive spending on data centres and chips by tech companies will pay off, or whether it resembles an investment bubble.

The Kansas Department of Health and Environment has issued a boil water advisory for the City of Eskridge, a small community in Kansas. Residents are being told to boil tap water before drinking or cooking until tests confirm the supply is safe. Similar advisories are typically lifted within 48 hours once water samples come back clean.

More than 27 citizen and environmental groups plan to hold a rally against data centers on October 6 in the Main Capitol Rotunda in Harrisburg, Pennsylvania. Organizers are expected to voice opposition to data center development in the state, citing concerns over energy demand, water use, and impacts on local communities. The coordinated event signals growing grassroots resistance to data center expansion across Pennsylvania.

Singapore's national water agency PUB has urged the public to avoid several areas across the city-state because of flash flood risks. The advisory comes amid heavy rainfall, and residents are being told to stay clear of affected low-lying spots until conditions improve. The warning is drawing wide attention as floods can develop quickly during intense downpours in Singapore.
