What changes are happening to the atmosphere?

The atmosphere is experiencing significant changes primarily due to climate change, driven by increased greenhouse gas emissions from human activities such as burning fossil fuels and deforestation. This leads to rising global temperatures, altered weather patterns, and increased frequency of extreme weather events. Additionally, atmospheric concentrations of carbon dioxide and other pollutants are rising, impacting air quality and contributing to health issues. Ozone depletion and shifting chemical balances are also ongoing concerns that affect both the environment and human health.
