Ozone layer, is it disappearing?

Protects against Ultraviolet radiation UV-radiation can give you skin cancer There is: UVA, UVB and UVC UVC most dangerous UVA least dangerous UVC stopped by ordinary oxygen UVB stopped by Ozone UVA not stopped

Ozone hole only over Antarctica

The ozone miracle Ozone is created when UVC collide with ordinary oxygen. UVC is completely stopped by oxygen Oxygen is created when UVB collide with ozone. Ozone will never disappear

Ozone in Sweden

Ozone variation

Ozone in the tropics

The strongest UV radiation

Ozone layer globally

Important facts about ozone Thinnest at equator Thickest at the northern hemisphere Only ozone hole around south pole Most ozone is produced at the equator and transported by the winds to the north and south.

Ozone layer will never disappear in the future. We have stopped dangerous HFC-gases that made the ozone layer thinner.
