Volcanic eruptions can significantly impact global climate change through several mechanisms, primarily by releasing gases and particulates into the atmosphere. Here’s how they contribute:
- Release of Aerosols:
- Sulfur Dioxide (SO₂): When volcanoes erupt, they release sulfur dioxide, which can convert into sulfate aerosols in the atmosphere. These aerosols reflect sunlight away from the Earth, leading to temporary cooling.
- Other Aerosols: Volcanic eruptions can also emit other aerosols (like ash and dust), which further contribute to cooling by scattering solar radiation.
- Greenhouse Gases:
- Carbon Dioxide (CO₂): Although less significant than human emissions, volcanic eruptions release CO₂, a greenhouse gas that can contribute to long-term warming if large amounts are emitted over time.
- Stratospheric Effects:
- Eruptions that reach the stratosphere can spread aerosols over a larger area and for a longer period, enhancing the cooling effect. For instance, the eruption of Mount Pinatubo in 1991 injected large quantities of SO₂ into the stratosphere, causing global temperatures to drop by about 0.5°C for a few years.
- Changes in Precipitation Patterns:
- Volcanic aerosols can alter weather patterns, affecting rainfall distribution and intensity. This can lead to droughts in some regions and increased precipitation in others.
- Long-Term Climate Effects:
- Prolonged volcanic activity can contribute to longer-term climate changes, although the direct impact is generally more pronounced in the short term.
While volcanic eruptions can lead to temporary cooling due to aerosol emissions, the long-term contributions to climate change are less significant compared to human activities.

There has been notisable reduction in ozone layer, particularly in the stratosphere, mostly because of human activity and it resulting depletion of ozone layer. The Antarctic ozone hole which forms each year over Antarctica is where this loss was most clearly noticed.
According to the theory that researchers may be concealing knowledge about ozone depletion. Peer reviewed publications and international evaluations like example from the world meteorological organisation and the United Nations environment programme these are open platforms for the promotion of scientific research and discoveries about ozone depletion.
The main cause of ozone depletion that is proven by scientific studies is the atmospheric release of ozone depleting substances (ODS) such as chlorofluorocarbons(CFCs). Under some circumstances, these compounds degrade ozone molecules causing the ozone layer to weaken.
But the amount of ODS in the atmosphere has significantly decreased. And this decrease of ODS results of international efforts made in the wake of the 1987 Montreal protocol, which restricted the manufacture and use of ODS. And this results in especially in areas outside of the polar region the ozone layer is beginning to rebound.
In conclusion, international efforts have contributed to reducing the consequences of ozone depletion, despite the fact that it was a major environment and issue caused by human activity. Maintaining transparency in sharing research finding and their consequences for international environmental policies, scientific community keeps an eye on the ozone layer and its recovery.
