Is Tree Planting A Get-Out-Of-Jail-Free Card On Climate?

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.

Kathmandu is one of the most polluted countries in the world--a title once caused by the excess smoke produced by brick creation in the city. However, after a 2015 earthquake destroyed much of the old technology used to fuel the brick industry, leaders took to leveraging updated technology with an increase in energy and production efficiency.

In California’s wildfire-prone Sierras, forest managers are turning to an ancient, if not quite intuitive, tool: more fire. In 2019, the Forest Service will manage 250,000 acres with controlled burns and “mechanical thinning,” using equipment to take out small trees. Though such plans face some hurdles, states across the country are adopting them, reducing wildfire severity while often benefiting ecosystems.

In the wake of more than 100 forest fires in Maule, Chile, hundreds of burned acres of forest are being replanted by three Border Collies named Das, Olivia, and Summer and an organization called Pewos. The dogs bound through miles of terrain with special backpacks that release native seeds to regrow the area. So far the dogs have worked in 15 forests in the region and plants are starting to come back.

In Indonesia, transferring land management rights to local residents is slow-going, but one community is setting an example for what can happen when the residents are in charge. Mandiri farmers formed a cooperative and began replacing hillsides; now, tourism to the area has increased and attitudes towards the land and community have changed.

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.

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.

London charges higher-emission vehicles every day they enter the city center, called the Ultra Low Emission Zone, on top of the already existing London Congestion Charge for non-electric vehicles to enter the zone. Since the charges were implemented, the city has seen an increase in electric vehicle adoption and improved air quality.

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.
