CO2 concentration records

CO₂ concentration records track the amount of carbon dioxide in Earth's atmosphere over time, typically measured in parts per million (ppm). These records show that CO₂ levels have risen significantly since the Industrial Revolution, mainly due to burning fossil fuels like coal, oil, and gas. Higher CO₂ levels contribute to global warming by trapping more heat in the atmosphere. Monitoring these records helps scientists understand climate change trends, assess human impact, and inform policies aimed at reducing carbon emissions to protect the environment.
