Carbon dioxide (CO2) is a colorless gas found in Earth's atmosphere. It is produced through natural processes (respiration, volcanic eruptions) and human activities (burning fossil fuels, deforestation). CO2 is a greenhouse gas, trapping heat in the atmosphere, contributing to global warming and climate change.
Over the past century, human activities have increased CO2 levels significantly. Prior to the Industrial Revolution, CO2 levels were around 280 ppm. Today, they exceed 410 ppm, the highest in 800,000 years. This rise in CO2 is linked to rising temperatures, melting ice, and ocean acidification. Monitoring CO2 is critical for understanding climate change's impact.
Methane (CH4) is a colorless and odorless gas present in the Earth's atmosphere. It is generated through natural processes like wetlands, termites, and geological sources, as well as human activities such as agriculture, livestock farming, and fossil fuel extraction. Methane is a potent greenhouse gas, having a significantly higher heat-trapping capacity than carbon dioxide. Its impact on climate change includes contributing to global warming and influencing weather patterns. Over recent years, methane concentrations in the atmosphere have been increasing, warranting careful monitoring and mitigation efforts to address its environmental implications.
