Project Puffin: A 50-year triumph that brought puffins back to Maine

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.

A startup is making buildings more eco-friendly by converting their energy needs from oil and gas to electric heat pumps. BlocPower is a Black-owned clean tech startup that provides a no money down lease option, making it financially accessible.

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.

The nonprofit Mahila Housing Trust provides women in India who are particularly vulnerable to extreme heat and heat-related illness with white solar reflective paint for the roofs of their homes. Painting the roofs white cools the inside of the homes by several degrees.

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.

Alongside clean energy, wind farms built on property leased from locals in Nebraska are generating jobs, income, and local taxes that keep small towns like Petersburg afloat.

The Office of Heat Response and Mitigation works to address the urban heat effect caused by intense summer temperatures. The Office has worked on several practices like coating streets and surfaces in light-colored, water-based asphalt treatments that reflect sunlight and absorb less heat than standard pavement. So far, 100 miles of residential roads have been covered in the treatment and roads with the treatment have an average surface temperature that is 10.5 to 12 degrees Fahrenheit lower than traditional asphalt.

A neighborhood group and a roofing company in Los Angeles, California, painted streets, parking lots, and a schoolyard with a “cool pavement” coating that reflects the heat from the sun. The coating keeping the surface cooler and providing relief from the urban heat island effect.
