Scientists have been monitoring the recovery of the ozone layer for 40 years since its discovery in 1985, but progress remains slow. The Montreal Protocol, an international treaty aimed at reducing ozone-depleting substances, has been effective in cutting emissions, but it may take until 2070 for a full recovery.
The ozone hole forms every Antarctic spring due to extremely cold temperatures and polar stratospheric clouds, which accelerate ozone depletion. Despite efforts to phase out CFCs and other harmful chemicals, many of these substances have atmospheric lifetimes exceeding 50 years, leading to ongoing ultraviolet radiation risks.
Research suggests that climate change may be influencing the rate of ozone layer recovery, complicating the process. Continuous monitoring and research are essential to understand how climate change feedbacks affect the healing process.
The international response to the ozone crisis serves as a model for what can be achieved through science, diplomacy, and policy convergence. It highlights the importance of coordinated, evidence-based action in protecting the environment.
