1. IntroductionHumanity is threatened by global warming due to the increase in CO2 emissions since the Second Industrial Revolution. Based on the “Global Warming 1.5 °C Special Report” from the Intergovernmental Panel on Climate Change, the average global temperature increased by approximately 1.09 °C after industrialization as of 2018, and the increase is expected to reach 1.5 °C between 2030 and 2052 [1].
