Carbon dioxide (CO₂) is one of the most well-known greenhouse gases. It contributes to the greenhouse effect by trapping heat in the Earth's atmosphere, leading to global warming and climate change. While CO₂ is naturally present due to various processes, human activities, particularly burning fossil fuels and deforestation, have significantly increased its concentration in the atmosphere since the Industrial Revolution. This rise in greenhouse gases, including methane and nitrous oxide, enhances the greenhouse effect, resulting in rising temperatures, altering weather patterns, and threatening ecosystems worldwide. Efforts to mitigate these effects include reducing emissions and promoting renewable energy sources.
