Across the United States, people are recognizing that climate change is a major threat to any vision of a healthy future. They are responding by developing solutions to not only avoid the health harms from climate change, but also actively improve health and limit climate change.
In Austin, Texas, city officials have grown increasingly concerned about their residents enduring more days with extreme heat. In particular, they worry that extreme heat events prevent young people from getting physical activity and harm people’s overall well-being.
Austin leaders decided to respond by increasing green space and tree shade around some of the city’s public schools, especially those that largely serve students of color or those in lower-income neighborhoods. More trees create cooler spaces for physical activity. They also help address climate change by decreasing the need for air conditioning, which use about 6 percent of all electricity produced in the United States. Trees are effective because green space and shade reduce temperatures over heat-storing concrete.
At first glance, planting some trees may seem like a limited and short-term approach in the face of a changing global climate. Trees, however, are an important climate solution because they remove carbon from the atmosphere. Increasing levels of carbon in the atmosphere causes climate change. We need more trees—lots more.
