Combining aquaculture and hydroponics, aquaponics unearths value in “waste” flows and re-routes them back into the economy. It’s an inspiring example of how a circular-economy business model can work.
The Orbiting Carbon Observatory satellite makes precise measurements of Earth’s carbon dioxide levels from space.

Peruvian glaciers have shrunk by 25% since 1987, causing water shortages in rural villages. But ancient technology could help manage this precious resource.

Climate change threatens the water supply of nations around the world. But it’s difficult to measure whether a region has sufficient water to satisfy the people who live there. Could satellites help?

New research forecasts that climate change will make multiyear stretches with low snow levels more common across western North America – bad news for water managers, farmers, foresters and skiers.

Millions of Americans rely on groundwater for their lives and livelihoods, but regulation is piecemeal. A new study maps groundwater wells nationwide and finds that they are drilling steadily deeper.
Sunburnt Victorian fields are set to become more common under climate change.

What exactly is inside those red fire extinguisher canisters, and does it work better than water?
The white “bathtub ring” around Arizona’s Lake Mead (shown on May 31, 2018), which indicates falling water levels, is about 140 feet high.

Western states adopted a 7-year plan in May 2019 to manage low water levels in the Colorado River. Now they need to look farther ahead and accept that there will be less water far into the future.
Is your community’s water tainted with lead? The data might not have been reported.

Flint’s highest recorded lead levels were typical for water systems that report problems. What’s more, a number of cities haven’t reported their lead issues.
The global water crisis means scientists face urgent decisions on how to foster water managers’ care. Here, the North Saskatchewan River with the Rocky Mountains, Banff National Park.

Over the past 20 years, Great Lakes water levels have gone from sustained multiyear lows to multiyear highs. Climate change is accelerating the transition between dry phases and wet phases.
Everything in an animal’s body is made out of cells. And these cells need chemicals, such as salt, in and around them to work properly. The chemical balance needs to be just right.

In many municipalities, aging water infrastructure is serving fewer people than it was built to accommodate. Out of sight has meant out of mind – but resulting changes in water quality may affect safety.
Melbourne’s water supplies are running low after years of drought.

Lead contamination is not just a problem for Flint, Michigan. It is an issue in many regions. One epidemiologist figured out how to measure past lead exposure using treasured biological samples.
The more fuel there is for the fire to burn, the bigger the fire. Leaves, trees and grass fuel the fire.
