  • The daring plan to save the Arctic ice with glass Audio icon

    The nonprofit Arctic Ice Project is testing an unusual approach to combat climate change: by scattering a thin layer of reflective glass powder over parts of the Arctic. By putting this material on top of the ice, they’re studying if the powder can protect the ice during the summer months and rebuild it over time. In one pond in Minnesota, just a few layers of the material made young ice 20 percent more reflective and delayed the melting of the ice. Other scientists question the impact the material can have on the Arctic ecosystem, but the approach could be a way to counteract the effects of global warming.

  • As Concerns Over Climate Change Rise, More Developers Turn to Wood

    Eastern Washington University recently built the first tall wood office building in the state joining hundreds of other large “mass-timber” projects in the United States. This growing industry constructs panels, beams, and columns from trees that need to be thinned to curb wildfires in forests. While wood buildings can be more expensive to build than ones constructed from concrete and steel, environmentalists are on board because wood can store carbon, which can help offset greenhouse gas emissions.

  • Soap on tap? A startup arrives in NYC with a plan to take the plastic out of cleaning products.

    To make food and cleaning products more accessible to those experiencing economic hardship, the startup Algramo has installed more than 2,500 automated bulk-dispensing systems throughout Chile where people can purchase an item and come back to refill it using the same container. Instead of competing against other consumer good companies, Algramo works with them to help change their packaging practices to reduce their plastic waste. Algramo is scaling the service to New York City and Indonesia to help cash-strapped and eco-friendly shoppers.

  • The art of fire: reviving the Indigenous craft of cultural burning

    A 3-year pilot is developing a traditional fire management program for First Nation communities using cultural burns, a practice banned for over a century. Cultural burns are used to reinvigorate the landscape so that seeds and berries grow and animals return. The low intensity, slow burns also reduce wildfire risks and other issues linked to climate change, such as infestations. Stories about cultural burns are being recorded from tribal elders to preserve the rich cultural knowledge about traditional fire management techniques. First Nations hope to be able to use cultural burns on their tribal lands.

  • University of Arizona researchers unveil new model for desert farming in warming world

    In an experimental garden in Arizona, scientists are seeing how to produce sustainable and local food in a desert environment. They’re growing plants under a photovoltaic “canopy” of solar panels that provide necessary shade for the crops and, at the same time, generate cheap, renewable energy for irrigation systems and farm equipment. So far, they’ve been able to grow basil, Anasazi red beans, and a special bell pepper. While not all crops will work in this system and scaling the garden has its challenges, learning how to grow food in the desert is necessary to adapt to a future with climate change.

  • Could 80,000 family woodlot owners be the key to saving the Acadian forest?

    Community Forests International created a carbon project to preserve Acadian forest. They measured and quantified carbon storage on small family-owned forest land, certified it by third-party standards, and sold the carbon offsets to an architecture and engineering firm. A conservation easement was also put on the land to ensure the forest’s longevity. The organization has stored enough carbon dioxide to equal the greenhouse gas emissions of 8,229 passenger vehicles driven for a year in three Wabanaki-Acadian forest preserves. The money raised helped buy some of the land to practice sustainable agriculture.

  • Who Can Breathe in Lane County?

    As smoke from local wildfires created an unhealthy outdoor environment, cities in Oregon looked to expand temporary housing options for those experiencing homelessness. While not all have been successful, the Portland area saw success from being able to rely on their "system for responding to severe weather, as well as the Multnomah County’s Emergency Management Department."

  • Can an Algorithm Help Solve Political Paralysis?

    Citizen assemblies bring together residents for in-depth discussions about solutions to social issues. This alternative form of democracy led to policy changes in many countries, including legalizing abortion in Ireland. In the UK, an algorithm was applied to form a 110-person “climate assembly.” In a multistage process, the algorithm selected a representative sample of the U.K.’s population, sometimes oversampling harder to reach groups to ensure inclusion. A small stipend was also offered to offset costs for people with lower incomes. The group submitted a final report with climate policy recommendations.

  • California May Need More Fire to Fix its Wildfire Problem

    Prescribed burns are considered the best way to contain catastrophic wildfires, and fires sparked by lightning or by Native Americans once burned more land in California than has burned in 2020's record-setting fires. But burning its way out of danger is hardly a simple matter for California now. Obstacles are many. Long-standing policies of aggressive fire suppression, plus climate-change-induced drought and pestilence, have amassed more fuel for fires. Dense populations in fire-prone areas, make for daunting logistical and financial obstacles.

  • How trucking eels is reviving a river

    Biologists are trapping baby eels in the Susquehanna River and are physically relocating them via trucks upstream past hydroelectric dams. These dams have interrupted the natural migration route the eels have traditionally taken, which has had unintended consequences for other ecosystems on the East Coast. While this technique, known as assisted migration, may be one way to save some species from climate change, some question whether the cost and conservation consequences are worth it. So far, biologists have have moved over 1 million eels since 2008.
