This research explores volcanic eruptions' role in atmospheric composition and Earth's climate. It examines gas emissions, such as sulfur dioxide and carbon dioxide, and their effects, including short-term cooling and temperature disruptions. Case studies, like Mount Agung (1963) and Mount Ruapehu (1995-1996), highlight ecological and economic impacts. The study further compares volcanic emissions to human-induced CO2 contributions, emphasizing their role in climate dynamics. The findings...
