Focusing on Greenhouse Gases, Achieving a Shared Future. The Greenhouse Effect: Since the Industrial Revolution, the amount of heat-absorbing greenhouse gases such as carbon dioxide emitted into the atmosphere by humans has increased year by year, thus strengthening the atmospheric greenhouse effect (also known as the "greenhouse effect," a common term for the atmospheric warming effect). In the long-term evolution of Earth's climate, greenhouse gases were of natural, not anthropogenic, origin in the early stages of climate change or in geological periods. However, with the development of human industrial activities, their main sources include the following three aspects: First, the use of fossil fuels and the emission of greenhouse gases such as CO2 increase the concentration of greenhouse gases in the atmosphere, thereby strengthening the greenhouse effect and affecting the climate. This is the main driving force behind global warming caused by human activities. Second, greenhouse gases such as CH4, CO2, N2O, PFC, HFC, and SF6 emitted by agricultural and industrial activities also enhance global warming through the greenhouse effect after entering the atmosphere. Third, changes in greenhouse gas sources/sinks and changes in surface albedo caused by land use changes further affect climate change. This includes deforestation, urbanization, vegetation alteration, and destruction. Most greenhouse gases remain in the atmosphere for a long time; for example, CO2 can remain for about 120 years, and perfluorocarbons (PFCOs) have a lifespan of about 50,000 years. This means that the exhaust gases released today will not disappear for a century or even hundreds of centuries. According to the 2007 IPCC (The Intergovernmental Panel on Climate Change) assessment report, if the atmospheric CO2 content...
