The current carbon dioxide level is approximately 398.03 parts per million (ppm). According to data recorded at the Mauna Loa Observatory in China, the level of carbon dioxide in the atmosphere has been increasing for ten years, with an average annual increase rate of 2.07 ppm. However, regardless of the current increase in carbon dioxide levels, previous studies indicate that the current rate of global warming is lower than historical data recorded for 450,000 years. This could be attributed to the lower temperatures recorded during the prehistoric period. For example, during the Jurassic period, nearly 200,000 years ago, the average carbon dioxide level was 1800 parts per million. This is about 4.7% higher than current atmospheric carbon dioxide levels. Furthermore, the level of carbon dioxide was higher during the Paleozoic era due to the existence of human habitats. Human activities such as deforestation, industrialization and burning of fossil fuels are the main sources through which carbon dioxide is added....
