Episode Overview
Title: An old Atlanta railway is becoming a cool escape
Date: July 24, 2026
Host: Dr. Anthony Leiserowitz, Yale Center for Environmental Communication
This episode of Climate Connections explores the transformation of a neglected Atlanta railway corridor into the Atlanta BeltLine, a 22-mile loop that is being developed as a leafy, shaded path for walking and biking, and will double as the world’s longest linear arboretum. The initiative aims to address urban heat and stormwater challenges posed by climate change, while also connecting neighborhoods and creating accessible green spaces for residents.
Key Discussion Points and Insights
The Atlanta BeltLine Project
- The BeltLine will form a 22-mile loop around Atlanta, transforming an overgrown and neglected railroad corridor into a vibrant urban greenway.
- The path will link parks, affordable housing, art, businesses, and public transit across the city.
- [00:07] “When complete, the Atlanta beltline will form a 22 mile loop around the city, linking parks, affordable housing, art businesses and public transit.” – Dr. Anthony Leiserowitz
The World’s Longest Linear Arboretum
- The path will be surrounded by hundreds of different plant and tree species, creating a unique, sprawling arboretum.
- This green corridor will offer significant ecological benefits, including:
-
Shading for walkers and cyclists
-
Improved air quality
-
Stormwater filtration
-
[00:13] “And hundreds of different types of plants and trees will surround the path, forming the world’s longest linear arboretum.” – Dr. Anthony Leiserowitz
Urban Connectivity and Accessibility
- The project will allow people to travel through 45 neighborhoods by foot or bike.
- [00:30] “And it’s a way that people can get through 45 neighborhoods either by bike or by foot, that is going to be completely shaded.” – Greg Levine
- The design ensures substantial shade, providing a “cool escape” from Atlanta’s increasingly hot climate.
Climate Change Adaptation
- Greg Levine, executive director of Trees Atlanta (the nonprofit managing the arboretum), explains that both old growth and newly planted trees are integral to the project.
- Trees are vital urban infrastructure in the face of growing climate extremes:
-
Help keep the city cool during heat waves
-
Filter stormwater during heavy rains
-
Support urban wildlife
-
[00:40] “These trees will help keep the city cool on hot days and they’ll filter stormwater when it rains. They’ll also create havoc for wildlife.” – Dr. Anthony Leiserowitz
Biodiversity and Community Engagement
- The BeltLine brings nature back into the city:
- [01:01] “In the evenings, you can hear insects. If you get here early in the morning, there’s birds flying all around.” – Greg Levine
- Over half of the arboretum is already completed.
- Along the path, signage, public art, and guided tours educate users about the ecosystem.
