  • Indigenous Elders Are at Risk of Freezing to Death Because Wood Is So Expensive

    A collaborative experiment between Indigenous community activists, tribal officials, loggers, nonprofits, and the U.S. Forest Service is delivering firewood to residents who need it for heating and cooking. The program, called Wood for Life, also doubles as a forest management initiative to thin out Arizona’s forests to prevent deadly wildfires. The shuttering of a local coal mine and the COVID-19 pandemic exacerbated this home heating crisis and group members in 2020 delivered a total of 650 cords of wood to several Indigenous nations.

  • Can global innovation competitions help unearth the next sustainability solution?

    Initiatives set up by NGOs and private-public partnerships aim to make innovation possible around the world and support sustainability entrepreneurs in countries that often don’t have access to those opportunities. The European Institute of Innovation and Technology set up the ClimateLaunchpad competition to provide entrepreneurship coaching and training to clean-tech finalists and the Uplink global platform from the World Economic Forum brings innovators and investors together to support sustainability ideas.

  • Meet the TikTok stars using viral videos to save the planet

    The growing account known as “EcoTok” on the social media app TikTok is working to expose more people to data about the climate crisis and tackle scientific misinformation. With more than 80,000 followers and 1.2 million likes, the account features short videos with scientists, students, and activists highlighting ways that young people can be more sustainable. Their ability to engage people in environmental and scientific issues has led to partnerships with TED Countdown and the UN Environment Programme.

  • Harnessing People Power to Protect Alaska's Last Remaining Wilderness

    A viral campaign from Indigenous activists, TikTok creators, and documentary filmmakers led to about 6.3 million letters being sent to federal agencies encouraging them to halt fossil fuel development in the Arctic National Wildlife Refuge. They created social media content and a toolkit for creators to use on their platforms that made it easy for the message to spread.

  • French Polynesia's pearl farmers combat climate change with sustainable practices

    A rapidly changing climate is shaking up how French Polynesian pearl farmers are doing business. Kamoka Pearl Farm is incorporating more sustainable practices like using its own oysters to create the nuclei that form pearls and using fish to organically clean the oysters instead of power washing them.

  • Planting crops — and carbon, too

    Maryland farmer Trey Hill became the first seller in a tech startup’s carbon marketplace, paying him $115,000 for initiating regenerative farming practices. By introducing cover crops, he has been able to sequester about 8,000 tons of carbon in the soil, which then buyers can purchase the credits to offset the carbon they produce. If more farmers get on board, supporters say it can be a tangible solution to curbing climate change.

  • How Solar Panels Could Help Save Struggling Farms

    As the amount of farmland decreases in the United States and climate change brings hotter and drier conditions, many farmers are turning to agrivoltaics — growing crops and installing solar panels on the same land — as a way to make ends meet. Research on a garden in Arizona showed that certain crops like tomatoes and chiltepin peppers were able to thrive under the shade of solar panels, while also improving the solar panels’ productivity. “It’s a very unique positive feedback,” said one of the researchers.

  • One, two, tree: how AI helped find millions of trees in the Sahara

    Tree mapping helps researchers understand deforestation and climate change, however the technologies used often miss trees that aren’t clustered. Researchers, in collaboration with NASA, used high-resolution satellite images, previously only available to commercial entities, to find a surprisingly large number of trees in the Sahara Desert. Using AI deep learning and one of the world’s most powerful supercomputers at the University of Illinois, they identified more than 1.8 billion trees, manually marking nearly 90,000 so the computer could “learn” which shapes and shadows indicated the presence of trees.

  • How Bison Are Saving America's Lost Prairie

    Tall grass prairie used to span across 13 states in North America. However, after settlers arrived grassland prairies were decimated. By reintroducing bison to the land along with seasonal fires, the nature conservancy, which manages the Joseph H. Williams Tallgrass Prairie Preserve in northeastern Oklahoma, resuscitated the prairie. The preserve is the largest tract of grassland prairie remaining in the world.

  • Soil: The Dirty Climate Solution

    More and more farmers are turning to regenerative agriculture techniques as a way to cut down on costs, increase crop yields, and sequester carbon into soil as a way to reverse the effects of climate change. One farming family in Minnesota switched to no tillage farming and also planted cover crops and used animals to fertilize their land. Some people question their methods, but these farmers saw their cost of production decrease and increased the amount of organic matter in their soil compared with their neighbors.
