It’s been 35 years since the sign­ing of the Mon­tréal Pro­to­col, which was an inter­na­tion­al effort to address the deple­tion of the ozone lay­er. Now, all these years lat­er, we’re won­der­ing — did we save the ozone lay­er? And, if so, can we save the cli­mate too?

In this week’s episode, Son­ak Patel and Han­nah Cun­ning­ham dis­cuss the Mon­tréal Pro­to­col and the envi­ron­men­tal cri­sis that was the dis­cov­ery of the deple­tion of the ozone lay­er. Did the Mon­tréal Pro­to­col work? Did we save the ozone lay­er? And, if we did, can we also band togeth­er to address the envi­ron­men­tal cri­sis of the 21^st cen­tu­ry: cli­mate change?
