Is ozone increasing?

As a keen observer of environmental trends, I've noticed recent discussions regarding ozone levels in our atmosphere. Could you provide a brief overview of the current state of ozone levels? Are they increasing, decreasing, or staying relatively stable? What factors are influencing these changes? Are there any specific regions or areas of the world where ozone levels are fluctuating more significantly? Additionally, how do these ozone level changes impact our environment and human health? I'm particularly interested in understanding the potential implications for climate change and air pollution.
