The hottest Water resources Substack posts right now

A strong "super" El Niño looks likely and, combined with already record-warm oceans and a powerful heat dome, will drive unprecedented heat, worsening droughts, fires, and chaotic weather over the next year.
Weather and water systems are more vulnerable than ever. Forecasting capabilities have been degraded by data cuts just as snowpacks and reservoirs hit record lows, raising the risk of surprise disasters and real shortages.
Energy politics are amplifying the crisis—war and fossil-fuel leverage are driving up prices while utilities and some politicians push back against rooftop solar and climate laws, even as cheap, flexible solar technologies offer a fast path to cleaner, decentralized power.

A vast freshwater reservoir was discovered under the seabed off the U.S. East Coast that could theoretically supply a city like New York for around 800 years.
Researchers think the water was trapped by ancient glaciers and sealed in sediment layers hundreds of metres below the seafloor, and some samples are already close to drinkable.
Similar offshore freshwater reservoirs may exist globally and represent a huge potential water resource, but accessing them will require major engineering, legal and political work.

Groundwater and aquifers are being depleted rapidly around the world, with many basins and underground reserves falling fast enough to threaten long-term water supplies.
Rising temperatures from climate change are increasing evaporation and plant transpiration, melting glaciers, and shrinking wetlands, all of which reduce how much fresh water recharges rivers and aquifers.
The shrinking freshwater supply is causing wells, lakes, and reservoirs to dry up, harming ecosystems and food production, and makes cutting fossil fuel use and wasteful consumption urgently necessary.

A new type of aerogel can purify seawater using only sunlight. This means it could help provide clean water in areas that really need it.
There is a huge problem with water scarcity around the world, and most of Earth's water isn’t drinkable. This breakthrough could change that by making desalination cheaper and more accessible.
The process of using this aerogel might create waste, but there’s potential for that waste to be used in making batteries. This could solve multiple problems at once.

Atmospheric rivers are low-level jets of air that carry huge amounts of water vapor.
When atmospheric rivers hit California, they can lead to extreme rainfall due to orographic lift.
Climate change is making atmospheric river events more intense by increasing the precipitation from these systems.

Long-term institutional investing can provide a unique edge in the financial market.
Establishing unconventional investment profiles can lead to great returns but might challenge conventional wisdom.
Harvard's approach to investing in water resources and farmland involves complex strategies and global acquisitions.

The village of Kallio, once submerged under a reservoir, has reappeared due to Greece's severe drought. This shows how drought can reveal forgotten parts of history.
Greece is currently facing a historic drought caused by extreme heat and lack of rainfall. These conditions are making water resources very limited and raising serious concerns.
Climate change and overtourism are worsening Greece's water issues. Managing water use sustainably is now more important than ever to balance human needs and natural resources.

The belief in a permanent drought due to climate change led German dam operators to overfill reservoirs before winter, worsening December floods.
Climate change predictions can influence human behavior like dam management, impacting flood risk.
Balancing water management practices with changing climate patterns is crucial to prevent exacerbating natural disasters.
