A huge ozone hole has opened this year over the Arctic. While ozone holes normally form in the Antarctic zone every year because winter temperatures drop to extremely low values, allowing high-altitude clouds to develop– the Arctic has more varying temperatures and…
A huge area of sustained ozone depletion has developed over the Arctic-Canadian region — too late for the winter season, too early for spring, and unusually strong for the northern hemisphere. The ozone layer is a natural layer of protective gas in the upper…
