  • It Spied on Soviet Atomic Bombs. Now It's Solving Ecological Mysteries.

    Environmental scientists are using modern computing software to correct, orient, and analyze satellite images from the Corona spy project, launched in the 1960s and ’70s to monitor the Soviet military. The images have revealed human environmental impacts, challenged long-held assumptions, and helped predict future challenges. Within the last two years alone, the images have contributed to new information about climate change including rock glacier movements in Central Asia, shoreline changes in Saudi Arabia, and ice loss in Peru, helping scientists fill in knowledge gaps.

  • 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.

  • New York's Real Climate Challenge: Fixing Its Aging Buildings

    A housing project in Brooklyn is taking nine apartment buildings and retrofitting them to be more sustainable and cut carbon emissions. Casa Pasiva is a $20 million project that aims to reduce heating and cooling costs because of updated machinery and thick exteriors that will improve air quality. Funding for these types of initiatives is not always certain, but a collaboration between a developer and a nonprofit, with some city financing, made this first-of-a-kind green building renovation in New York possible.

  • Hurricane Sandy battered NYC 8 years ago. Since then, how has the city shored up against future superstorms? Oyster castles.

    As a way to soften the impacts of a future storm, an artificial oyster reef was installed in New York City. This green infrastructure can absorb the shock of waves and decrease the amount of flooding, as well as build up the shore over time effectively reversing erosion. Environmentalists argue that this type of barrier is more cost-effective than traditional seawalls and will adapt to sea level changes over time.

  • Could Carbon Dioxide Be Turned Into Jet Fuel?

    Scientists at Oxford University have come up with a process that could turn carbon dioxide into jet fuel. The greenhouse gas, which is a major contributor to climate change, is constantly emitted by the aviation industry and this method would allow for that gas to be recycled into a liquid fuel for flights. Scaling the experiment has its challenges, but the process could result in net-zero emissions from airplanes.

  • Could Seaweed Help Save Us From Climate Catastrophe?

    Seaweed aquaculture is a growing field that scientists are investigating for a number of climate-related uses, from reducing methane emissions in livestock to replacing plastic in packaging. Governments, startups, and researchers around the world are getting into the algae business that is also helping to create new jobs. There are challenges with scaling many of these products, but recent research for many of these initiatives have shown signs of early success.

  • The rise of the land salmon

    In Florida, a land-based salmon farming operation has optimized the ideal conditions for fish to be raised sustainably on land. “There is no winter here, there are no diseases, there are no sea lice. We optimize everything the fish needs," explains the company's chief sales and marketing officer. Although the practice is still "in its infancy" and struggles to return a profit, it has caught on elsewhere and land-based salmon are now sold in a variety of grocery stores.

  • How A 24-Year-Old CEO Makes Sustainable Tees from Milk

    After witnessing milk going to waste on his uncle dairy’s farm in China, Robert Lou came up with the idea to turn the leftover milk into clothing. It takes five glasses of milk to produce one t-shirt and he’s sold over 3,000 of them since launching his company Mi Terro. He hopes to use 15 percent of the world’s food waste in 20 years to lower greenhouse gas emissions and supply income to farmers. He’s also piloting a new flexible packaging material out of grain products.

  • The world's fastest-growing source of food

    Local villages along the coast of India are seen as a model for large-scale seaweed cultivation, which can be a form of sustainable agriculture and climate mitigation. As the country’s land is being lost to soil degradation, seaweed cultivation has had a positive socio-economic impact on the communities. About 1,200 families, mostly women farmers, are involved in collecting seaweed for industrial use, allowing them to increase their economic independence.

  • Reusing, recycling, rethinking

    Mason & Greens is a zero-waste store that reduces environmental impact by selling package-free items, from shampoo bars to organic produce. Dry goods and the wines, oils, and kombucha on tap are bought with reusable containers and priced by the ounce, which reduces plastic waste and allows customers to buy only what they need. In addition to minimizing products' carbon footprints, the store has been profitable since it opened and the owners say that, while prices are initially higher for consumers, reusable products may be less expensive in the long run because they don’t have to be replaced as frequently.
