Ozone Hole Plutus Ias What is the ozone hole? each year for the past few decades during the southern hemisphere spring, chemical reactions involving chlorine and bromine cause ozone in the southern polar region to be destroyed rapidly and severely. this depleted region is known as the “ozone hole”. The environmental crises of the past often seem to disappear—have problems like acid rain and smog been solved?.
Ozone Hole Continues Shrinking Wordlesstech In much needed good news for the environment, scientists have announced that the 2025 antarctic ozone hole was relatively small and short lived, confirming the long term trend towards the recovery of earth’s protective shield against the sun. The ozone layer plays a vital role in making the planet habitable for us and other species by absorbing most of the sun’s ultraviolet radiation. but, during the 1970s–90s, humans were emitting large quantities of substances that depleted the ozone layer. this led to the creation of ozone holes at the earth’s poles, exposing life to higher levels of ultraviolet radiation and increasing. In 1985, scientists discovered a “hole” in the ozone layer over antarctica that opened up during the austral spring, between september and december. this seasonal ozone depletion was suddenly allowing uv rays to filter down to the surface, leading to skin cancer and other adverse health effects. Antarctic ozone today: the 2025 ozone hole is growing and now covers 20 million square kilometres (msqkm), much larger than average. the polar vortex is near its maximum extent and covers 32 msqkm, about average.

How the ozone hole was discovered the concern over ozone depletion dates back to 1985, when scientists identified a growing hole in the ozone layer above antarctica. To monitor the state and recovery of the ozone layer, each year, the final diameter and depth of a ‘hole’ that opens annually in the ozone layer over antarctica is measured. for 2024, the hole over the earth's southern pole was relatively small compared to other years.

Ozone depletion and the ozone hole have generated worldwide concern over increased cancer risks and other negative effects. the ozone layer prevents harmful wavelengths of ultraviolet (uvb) light from passing through the earth's atmosphere.
