  • 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.

  • 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.

  • Wildfires are killing California's ancient giants. Can seedlings save the species?

    The United States National Park Service is planting giant sequoia tree seedlings in groves that were decimated by extreme wildfires in Sequoia and Kings Canyon National Parks. The effort aims to preserve the endangered species as the organization doesn’t believe the trees in these areas will regenerate on their own.

  • Minnesota-grown technology helps scientists track wildlife around the globe

    The Minnesota-based company Advanced Telemetry Systems develops trackers specifically designed for hundreds of different animals. These devices allow researchers to do things like find invasive species, learn more about critically endangered species, or better understand population declines.

  • Rewilding in Argentina helps giant anteaters return to south Brazil

    A rewilding project at Iberá National Park in Argentina is reintroducing giant anteaters where they were previously considered extinct by bringing orphaned pups onto wild, protected land and allowing them to roam freely.

  • In Oregon, a youth program prepares vulnerable landowners for wildfires

    Oregon’s Community Wildfire Protection Corps pays young adults to remove overgrown brush to make fire-safe buffers around the homes of people who are older, disabled, or without financial means. At the same time, the youth who participate receive training for careers in wildland firefighting.

  • Climate change is ravaging the oceans. Some startups see a solution in marine carbon capture

    Marine carbon capture, a term for various methods that trap carbon deep in the ocean, can help mitigate climate change by reducing the amount of the greenhouse gas in the atmosphere. Startups around the U.S. are advancing helpful technologies.

  • Making cities 'spongy' could help fight flooding — by steering the water underground

    The concept of “sponge cities” is taking off as a way to prevent flooding. This style of urban design focuses on creating environments that absorb more water with plants and open ground as opposed to pipes and concrete.
