Determining the Atmospheric Variation and Future Climate Change: An Approach Based on Paleoclimate Studies | Chapter 6 | Challenging Issues on Environment and Earth Science Vol. 7

Carbon dioxide (CO2) concentrations have been quickly increasing since the industrial revolution in the 18th century, indicating the impact of global warming. The atmosphere is made up of a variety of gases, and the general composition of these gases remains consistent for the ecosystem's growth. The Earth's weather and climate pattern were influenced by minor variations in air composition. As the amount of CO2 and other greenhouse gases in the atmosphere increased, the sun's radiation was absorbed, causing the earth's temperature to rise. Climate change occurred multiple times in the geological past, according to Paleoclimatic studies. The concentration of oxygen in the atmosphere varies due to a variety of natural factors. The CO2 level was extremely high. CO2 concentrations range from 7000 to 350 parts per million (PPM), oxygen (O2) concentrations range from 1% to 35%, sea level ranges from 450 to (-)50 metres below current sea level, and the Earth's average temperature ranges from 29 to 11 degrees Celsius. In comparison to the present, the sun's brightness ranged from 95% to 100%. Throughout geological history, Earth has experienced various warm and cold periods. We (humans) are currently living in a short time cycle on Earth, necessitating research into the planet's future climate. Attempting to analyse Paleo-climatic change across geological time, impacting causes, and observing that average atmospheric CO2, O2, and Earth's average temperature The temperature and water level were both significantly higher than they are now. Prepared the influence of CO2 and O2 on flora, animals, and natural disasters based on observed facts. Also developed the line diagram, which suggested that atmospheric CO2, O2, Earth's average temperature, and sea level will naturally grow in the future, affecting the environment in a variety of ways.
