Good news, the Ozone layer is healing. This isn’t a miracle, but a collective global climate change effort made by scientists and world leaders. Interestingly, the ozone layer blocks ultraviolet (UV) tradition from the upper atmosphere that harms humans and plants.

Tragedy struck in 1985 when researchers found the ozone “hole”, a result of human-emitted chlorofluorocarbons (CFCs). These depleting chemical and greenhouses gases were actively found in refrigerators and aerosol spray serving as coolants.

This hole was discovered in the ozone over the south pole. After further research, there was a prediction our ozone layer would collapse by 2050 if nothing was done. This would cause various skin cancers, destroy marine life and even crops.

The world had to respond and fast. Dr Susan Solomon led a team to the south pole to measure the extent of the damage. She and her team gave a report to the world stage, calling for politicians and world leaders to act fast to save our planet.

In 1987, more than 200 countries signed the Montreal Protocol which stopped the production and consumption of CFCs. We are currently en route to the Ozone layer recovery.

The Montreal Protocol treaty ( now the Kigali Amendment) was expanded to include hydrofluorocarbons (HFCs), CFCs and hydrochlorofluorocarbons (HCFCs) replacement gases. This remains the only treaty signed and agreed by all nations so far and is exactly the push we need for climate change.

“The Montreal Protocol began life as a mechanism to protect and heal the ozone layer. It has done its job well over the past three decades. The ozone layer is on the road to recovery. The cooperation we have seen under the Montreal Protocol is exactly what is needed now to take on climate change, an equally existential threat to our societies,” said UN Secretary-General Antonio Guterres.

Some particles of the banned halons and chlorofluorocarbons still remain in the atmosphere, probably for years to come. The ozone layer currently fluctuates in size annually, reaching its largest point during the coldest months. These months are from late September to early October in the southern hemisphere.

Sadly, recent findings show that ozone depletion could increase if we don’t reduce global greenhouse emissions rapidly. There’s currently a push for greener energy, electric vehicle automobiles and the phasing of coal and plastic.

There is an abundance of wind, sun and hydropower to fuel our daily lives. Even though this transition can’t be immediate, using a kinder natural gas is the way to go. World Ozone day happens every September 16, we can only hope to celebrate beating climate change.
