Supernovas May Have Triggered Deadly Ancient Climate Shifts, and They Could Happen Again
New research links nearby supernovas to drastic shifts in Earth’s ancient climate. These cosmic explosions may have eroded the ozone layer, triggered global cooling, and even caused mass extinctions. Tree ring data supports the theory, raising concerns that future stellar events, like the expected Betelgeuse explosion, could again pose serious at...

Space Research Reveals How Icy Comets and Asteroids Could Reshape Earth-Like Planets
New scientific models and telescope observations from 2024 and 2025 reveal how comet and asteroid impacts can change atmospheres on Earth-like exoplanets, potentially supporting life or triggering climate disruption.

Illegal Ozone-Depleting Gases Traced To China: Study
Industries in northeastern China have spewed large quantities of an ozone-depleting gas into the atmosphere in violation of an international treaty, scientists said Wednesday.

Someone's Secretly Making Ozone-Depleting Chemical, Suspect Scientists
Emissions of a banned, ozone-depleting chemical are on the rise, a group of scientists reported Wednesday, suggesting someone may be secretly manufacturing the pollutant in violation of an international accord.

Environment Ministry To Develop Next Generation Refrigerants
The Ministry of Environment, Forest and Climate Change (MoEFCC) has announced an ambitious collaborative research and development programme to develop next generation, sustainable refrigerant technologies as alternatives to HFCs.

Refrigerator Coolants Contribute to Ozone Depletion: NASA
A class of chemical coolants used in refrigerators and in home and automobile air conditioners contributes to ozone depletion by a small but measurable amount, says a new NASA study.

New ozone-depleting gases found in atmosphere
Worried scientists said today that they had found four new ozone-destroying gases in the atmosphere, most likely put there by humans in the last 50-odd years despite a ban on these dangerous compounds.

Acid rain, ozone depletion led to mass extinction 250 million years ago
Acid rain and ozone depletion fuelled extinction of 90 per cent of marine species and 70 per cent terrestrial species around 250 million years ago, a new study has found.
