The Forest Underground: How an Australian Missionary Regrew the African Sahel

Austria rolled out the KlimaTicket, an annual pass that gives the holder access to all forms of public transportation in the country, to encourage increased use of public transport with an eye toward climate change mitigation. The uptake has exceeded expectations with 134,000 tickets sold within just the first two months, but it's still unclear what effect the program will have on the country's carbon emissions.

After years of drought and land-clearing that left Niger with few trees left, the country now boasts about 200 million trees, which have mostly been reestablished naturally. While the effects of climate change could threaten the future of these trees, this method has also increased crop yields in villages. This model of letting trees grow back with little human influence could be implemented in other countries.

In Kenya, like other countries in the world, deforestation is the major driver of tree cover loss. To solve this, a local startup called Seedball Kenya has developed the seedball technology whereby seeds of indigenous tree and grass species are coated with charcoal waste mixed with nutritious binders then thrown like balls into the planting grounds.

Scientists are testing if adding alkaline substances to seawater can allow oceans to absorb more carbon dioxide emissions. Early tests suggest this could be a potential way to combat climate change, but there are still many questions about how this can scale, how it impacts the natural ecosystem, and if it’s cost effective to implement.

Beavers and the dams they build have been found to be tools against climate change as the planet’s temperature continues to rise. Dams slow water down and allow it to seep into the Earth, providing groundwater for humans, and also cools down both water and air temperatures. Beaver dams also create wetland ecosystems that are practically resistant to wildfires.

New Jersey schools are working to make climate education widespread by implementing general education standards that include climate change education in every grade and subject. These new education standards have been inspiring students to brainstorm solutions to climate-related issues like reducing food waste and increasing coastal resiliency. The state has also earmarked $5 million to help local teachers attend professional development sessions to teach them how to create new climate change-focused lesson plans.

After a clean air zone was created in London, where vehicles have to pay a daily fee to enter unless they meet strict pollution standards, more young students in the area began walking and biking to school.

In 2020, Nigeria's Centre for Community Empowerment and Poverty Eradication (CCEPE) and Small Scale Women Farmers Organisation of Nigeria (SWOFON) began to train women farmers on the use of dung and plant wastes as organic fertiliser and pesticides; to date, CCEPE has trained 40 women farmers in Asa and 20 women farmers in Kaima, resulting in more bountiful harvests and economic savings.

Following the success of New York City's divestment of pension funds from fossil fuels, a process that started in 2015, other cities around the US are exploring ways to achieve net-zero portfolio emissions. In most cases, the divested pension funds have performed at least as well financially as a city’s non-divested funds.

Students at Catholic University of America in a net-zero design course are analyzing church structures and making suggestions for green improvements to address the climate crisis, reduce carbon emissions and support the Vatican’s Laudato Si’ mission to conserve energy and protect the planet. Though in its early days, the course has proven beneficial for U.S. dioceses, and students say it’s impacted the way they see architecture and design, and how it can have implications tied to the environment.
