What is global warming? Water vapor, which consists of various gases in the atmosphere, carbon monoxide (CO), carbon dioxide (CO2), ozone (O3), CFC (chlorofluorocarbon), methane (CH4), diazotoxide (N2O), etc. The gases trap some of the heat falling on the earth from the sun's rays. Thus, it ensures that the earth is at a comfortable temperature for all biotic species. This feature of the atmosphere is called the greenhouse effect. Due to excessive formation and accumulation of greenhouse gases, industrial and technological changes, excessive consumption of fossil fuels, intensive growth of population, standard of living and human activity, increase in the temperature of the troposphere layer. leads to contraction. Such a situation sets the stage for many life-threatening problems.Global warming is a chain of disasters caused by a significant increase in the earth's temperature, forest fires, desertification, melting of glaciers, increased water, excessive precipitation and continuous formation of floods and excessive erosion. As a result of global warming, natural disasters lead to changes in the climate system. The history of global warming During glacial and interglacial periods in history, important ecological and climatic changes occurred, and some species of biotics became extinct, while others did. These events are completely influenced by the cycle and conditions of nature. After the transition to a regulated regime in the late Mesolithic, the climate was more or less the same until recently. However, about 30 years ago, it began to change rapidly. Evidence obtained through the science of paleoecology proves that the climate system is not at a constant level. This is not a natural process and develops entirely depending on human activity. According to a study by the Ministry of Environment and Forestry, it contributes to energy use, industry, forest burning and destruction, agricultural activities and global warming.Global warming Download 143.93 Kb.
