What's needed to get spring Chinook back to Walla Walla? Cooperation — and patience

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.

During the Industrial Revolution, farmers began harvesting monoculture crops which produced promising profits but proved harmful to the soil and weakened the immune capabilities of native plants. Lately, however, permaculture practices have been on the rise amongst farmers to better diversify their yields and reduce reliance on chemicals.

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 Jamaica, locally-led coral nurseries are working to restore the coral reef that have been lost to natural and manmade disasters. These organizations have small coral gardens where they can grow free of danger and when they’re big enough, are transported to a reef. With coral and fish being so codependent in the underwater ecosystem, the regrowth of coral has meant an increase of fish and fishing for the country, which many people rely on for their livelihood.

Scalesia, is a species of tree native to the Galapagos Islands that is quickly disappearing thanks to human activity. With much of the island's wildlife dependent on this tree, the ecosystem is threatened with the tree's extinction. Conservationists have taken action, however, by planting thousands of the trees as part of a shade-grown coffee operation.

Local Ocean Conservation is in Watamu, Kenya has made approximately 21,000 turtle rescues and "treated more than 650 turtles in its rehabilitation center and clinic" since it's inception in 1997. The group responds to fishermen who have accidentally caught turtles in their nets and then remunerates the fishermen for their "time, effort, and phone calls." This incentive-based relationship combined with a ban on the international tortoiseshell trade has helped decrease the poaching of turles, and the group has now expanded their efforts to include more initiatives to protect the endangered species.

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.

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.

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.
