How oxygen influence climatic change?

Oxygen itself does not directly influence climate change, as it is a stable gas that makes up about 21% of Earth's atmosphere. However, the burning of fossil fuels and deforestation, which release carbon dioxide and other greenhouse gases into the atmosphere, can deplete oxygen levels and contribute to climate change. Additionally, changes in oxygen levels in the oceans can impact marine ecosystems and contribute to climate change through feedback loops. Overall, while oxygen itself does not directly cause climate change, human activities that affect oxygen levels can indirectly contribute to the problem.
