  • Energy efficient homes mean less air pollution. But are they affordable?

    To reduce greenhouse gas emissions that contribute to climate change and air pollution, Habitat for Humanity Salt Lake Valley is building airtight homes that will also reduce energy costs and be affordable for people experiencing economic hardship. The home are largely being built by volunteers, so the process has been slow and there have been mistakes in building the homes. However, the homes are estimated to reduce carbon dioxide emissions by 4.9 tons a year.

  • Green teen memes: how TikTok could save the planet Audio icon

    Many young TikTok users are sharing videos about environmental issues, like climate change and biodiversity, and it is leading to resource sharing, personal connections, and people reaching out to learn more about environmental topics like gardening, soil restoration, renewable energy, and environmental racism. Some believe the Covid-19 lockdown has increased engagement even further. A subculture called “grass TikTok” emerged to share information about plant species and has nearly 380 million views. The potential ban of TikTok in the US could lead to declining biodiversity engagement online.

  • 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.

  • In Slumping Energy States, Plugging Abandoned Wells Could Provide an Economic Boost

    North Dakota is using some of its COVID-19 pandemic relief funds to plug 239 abandoned oil wells and reclaim 2,000 acres of lands. Abandoned wells can contaminate groundwater and leak methane that is hazardous to human health and contributes to climate change. While not everyone agrees that the funds should be used to plug wells, state officials say the economic relief program is keeping about 600 oilfield workers employed.

  • Fragile cities are being inundated with people fleeing the impacts of climate change. How can they cope?

    Durable Solutions Initiative (DSI) aims to create long-term solutions to help internally displaced people in under-resourced urban areas, many of whom fled climate-related disasters. DSI relies on ideas from the displaced communities about how to move towards self-reliance. In Somalia, the participatory and locally-created approach led to Midnimo I, a donor-funded initiative that created short-term jobs, built or upgraded community-prioritized infrastructure projects like schools and hospitals, and improved relations between authorities and displaced communities, benefiting nearly 350,000 people directly.

  • How a Young Activist Is Helping Pope Francis Battle Climate Change

    Molly Burhans, a young cartographer and environmentalist, is using GIS technology to map out the Catholic Church’s global property holdings to encourage them to improve the environmental impact on the lands they own. Burhans’ organization called GoodLands has been working with various parishes and dioceses to help Church leaders — including Pope Francis — understand their vast landholdings. While finances and COVID-19 have impacted her progress, Burhans’ maps have been used for other purposes like mapping Catholic radio stations in Africa and tracking the whereabouts of priests accused of sexual abuse.

  • The Radio Station at the Heart of a Fishing Community

    Kadal Osai (Sound of the Sea) is a radio broadcast with programming designed for fishers and their families since 2016. It reaches about 50,000 people from 30 fishing villages within a 15-kilometer radius of the station’s headquarters. Twelve radio jockeys provide 24-7 programming, with climate change and marine conservation two popular topics. The programming has provided a conservation mindset for many local fisherfolk, leading to behavior changes and helping them adapt to the rapidly changing world. The shows have shifted how they value the lives of sea creatures and what the ocean provides more broadly.

  • 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.

  • Cold Hard Cash for Your Greenhouse Gas

    Refrigerants being used in old air conditioners or grocery story cooling systems leak into the atmosphere contributing to global warming. Tradewater, a company in Illinois, picks up these containers, destroys the refrigerants, gives them cash, and then sells them as carbon offset credits. They collect up to 250,000 pounds of refrigerants per year, but there is still more out there. Supermarkets in the United States could switch to more natural refrigerants, but barely 1 percent are known to have done that. Getting rid of these refrigerants can be an important solution to combating climate change.

  • An unusual snack for cows, a powerful fix for climate

    A farmer on Prince Edward Island fed his cows seaweed and noticed that they produced more milk and had better pregnancy success. A study of his cows found that they also reduced methane emissions by about 18 percent, a decent amount that could be beneficial in combating climate change. The farmer is now part owner of North Atlantic Organics, which produces seaweed supplements for livestock. Now, other companies around the world are popping up to do the same thing and scale this climate solution.
