Earth’s protective layer is healing. What’s behind the change and what does it mean for the environment?

There’s good news to report about the environment. The Earth’s ozone is set to fully recover within the next four decades. A new United Nations report indicates efforts to reduce chemicals that eat into that protective layer of Earth’s atmosphere are paying off. 

Joining the discussion: 

• David Fahey is Director of the U.S. National Oceanic and Atmospheric Administration and Co-Chair of the Montreal Protocol’s Scientific Assessment Panel.
• Yixing Xu focuses on clean energy technology and energy policy as research director for Breakthrough Energy Sciences.
• Michael K. Dorsey is director of Arizona State University’s Sustainability Solutions Service, and a chair professor at ASU’s College of Global Futures. 
• Sweta Chakraborty is CEO of “We Don’t Have Time U.S.”

A climate success story: The ozone layer is on track to recover within 4 decades.

The healing of the Earth's invisible shield is an inspirational example of the world coming together to address global challenges like the climate crisis.
