Ozone Layer Healing as Harmful Chemicals Decline, MIT Study Confirms

Breaking News, Climate Actions, Fact Check, Learning & Developments

A new study by the Massachusetts Institute of Technology (MIT) has confirmed that the ozone layer over Antarctica is recovering, thanks to global efforts to reduce ozone-depleting chemicals like chlorofluorocarbons (CFCs). The study published in Nature on March 5, 2025, provides the strongest evidence yet that human intervention, rather than natural climate variations, is responsible for this progress. The ozone layer, located in the stratosphere 15 to 30 kilometers above Earth, acts as a protective shield, absorbing harmful ultraviolet (UV) rays from the sun. In 1985, scientists discovered a recurring seasonal “hole” in the ozone over Antarctica, allowing dangerous UV radiation to reach Earth's surface, increasing the risk of skin cancer and environmental damage.

New Study Warns Methane Emissions Could Hinder Ozone Layer Recovery

Breaking News, Climate Actions, Environment, Learning & Developments

A new study has highlighted the complex relationship between methane emissions and the recovery of the stratospheric ozone layer warning that rising methane levels could slow ozone restoration especially in polar regions. The ozone layer, which shields Earth from harmful ultraviolet radiation, has shown signs of recovery due to global efforts like the Montreal Protocol. However the study published in Advances in Atmospheric Sciences, suggests that future ozone replenishment remains uncertain due to global warming and human activities. Researchers from Beijing Normal University emphasize that methane plays a dual role while it is a potent greenhouse gas driving global warming, it also triggers complex chemical interactions that impact ozone levels. Understanding these dual effects is ...

Huge Success for Ozone Layer: Scientists Hail Rapid Decline in Harmful Gases, Thanks to Montreal Protocol

Breaking News, Climate Actions, Environment

Scientists said on Tuesday that international efforts to protect the ozone layer had been a "huge success" after they revealed that the harmful gas in the atmosphere is declining faster than previously thought. The Montreal Protocol, signed in 1987, aims to detect ozone-depleting substances found mainly in refrigerants, air conditioners, and aerosol sprays. New research has found that atmospheric levels of hydrochlorofluorocarbons (HCFCs), harmful gases that cause holes in the ozone layer, will rise in 2021—five years earlier than predicted. "This is a big achievement. We can see that things are going in the right direction," the lead author of the study, Luke Western, from the from the University of Bristol in England, told AFP. The most harmful CFCs were phased out in 2010 to...
