Urban activities — think construction, transportation, heating, cooling and more — are major sources of greenhouse-gas emissions. Today, a growing number of cities are striving to slash their emission to net zero — here’s what they need to do.
Worry over the planet’s future is taking a toll on emotional well-being, researchers say. Here’s how to cope so we don’t lose hope for our planet and for ourselves.
To understand what might be lost, ecologist Janet K. Jansson taps molecular methods to explore Earth’s underground microbes, from the permafrost to the grasslands
The technology could transform how growers protect their harvests, by detecting plant diseases very early on. But the challenge is to develop tools that are as affordable as they are effective.
The only way for humanity to solve its environmental problems may be to abandon our quest for continual economic expansion. It’s time to study what a future of degrowth might look like, some researchers say.
There are two types of wildfire in the state, and they’re on the rise for different reasons. Each needs a distinct management approach, a researcher says.
Where other species succumbed, the killifish survived contaminated habitats. It’s a finding that could help researchers understand environmental risk factors for humans.
Evidence that the approach helps to save trees, preserve ecosystems and reduce carbon emissions is often hard to come by. But it can succeed if it’s done right, says an economist.
Peoples who live close to nature have a rich lore of plants, animals and landscapes embedded in their mother tongues — which may hold vital clues to protecting biodiversity
Getting our homes and workplaces to be energy efficient has major benefits — but not when it is done one window at a time. Here’s why deep retrofits and biomaterials are key to more sustainable living.
ACs and refrigerators help keep people safe — but they also further warm the planet. Scientists are working on eco-friendlier solutions as global demand for cooling grows.
The wet landmasses, though inherently impermanent, have been essential to both people and wildlife for thousands of years. But recent shifts have brought on some rapid losses that worry scientists.
