As of October 2023, atmospheric carbon dioxide (CO2) levels are approximately 420 parts per million (ppm), continuing an upward trend due to human activities like fossil fuel combustion and deforestation. This increase poses significant challenges for climate change, contributing to global warming and related environmental impacts. Monitoring CO2 levels is crucial for understanding and addressing climate change.
