  • Nature's Carbon Sponges: Restoring Meadows in the Sierra Nevada

    The Nevada Irrigation District is restoring meadows, and therefore their carbon-sequestering abilities, in the Sierra Nevada mountains that were degraded by humans through things like building dams and mining.

  • Beavers Are Back in London — and They're Thriving

    A volunteer-run community organization is reintroducing beavers to London as part of a larger rewilding effort. The beavers are alleviating flooding and helping biodiversity thrive in the eight-hectare public park they live in by building dams and canals.

  • Inside the Icelandic plant turning CO2 into rocks

    A direct carbon capture plant in Iceland sucks carbon dioxide out of the air, mixes it with water, and pumps it underground to help combat climate change. When the mixture reaches the basalt bedrock, it causes a chemical reaction that turns the carbon into a solid so it can be stored underground in the porous rock.

  • U.S. East Coast adopts 'living shorelines' approach to keep rising seas at bay

    Contractors and homeowners in Maine are installing living shorelines to deal with the effects of rising sea levels and stronger storms caused by climate change. As opposed to concrete jetties and breakwaters, living shorelines use natural materials like logs, salt-tolerant plants, and coconut fiber to protect the land from erosion and create valuable habitat for local animals.

  • Food waste is a billion-dollar problem. Can this spray make a difference?

    Researchers in India developed a spray that is applied to mangoes to extend their shelf life by about a week, reducing food waste and increasing farmers’ profits.

  • The best coffee for the planet might not be coffee at all

    “Beanless coffee” companies around the world are taking inspiration from coffee substitutes of the past to create a drink that mimics coffee’s flavor and caffeine content that is more climate-resilient with less of an environmental impact.

  • Carmakers give up on software that avoids kangaroos

    Fence posts that flash blue and yellow lights while emitting a high-pitched noise when they detect oncoming car headlights are preventing car crashes involving kangaroos and wallabies in Australia. The practice is known as virtual fencing.

  • Biochar Is ‘Low-Hanging Fruit' for Sequestering Carbon and Combating Climate Change

    Biochar is an organic material that can be mixed with soil to improve soil health, increase crop production, and sequester carbon. To make it, wood or other biomass is heated at high temperatures in an oxygen-deprived environment, like a kiln.

  • Mini radio tags help track ‘murder hornets' and other invasive insects

    Scientists are using radio tracking technology to track invasive species like “murder hornets” to prevent them from overrunning the environment. The tagged hornet leads scientists to their nest, allowing them to eliminate the hive before an invasion occurs. Neither the U.S. nor Canada has had a giant hornet sighting since the last nest was destroyed in 2021, but this technology allows researchers to be prepared.

  • Dairy Digesters Promise to Cut Methane — Unfortunately, They Might Be an Inefficient Band-Aid

    Dairy digesters are oxygen-free systems that break down organic material like manure and turn methane into “biogas,” which can be used to generate electricity or processed into transportation fuel. Once heralded and championed by the California Department of Food and Agriculture as one of the most cost-effective emissions reductions programs, new research shows the real cost is up to 17-times more than what state and industry officials have publicly claimed.
