Global warming refers to the increase in global temperatures. In the past 100 years or so, the global average temperature has undergone two fluctuations of cold-warm-cold-warm, which is generally seen as an upward trend. After entering the 1980s, global temperatures have risen significantly. From 1981 to 1990, the global average temperature rose by 0.48°C from 100 years ago. The main cause of global warming is the fact that humans have used fossil fuels (such as coal, oil, etc.) for most of the past century, and discharged a large amount of CO2, or greenhouse gases, into the atmosphere Because these greenhouse gases are highly transparent to visible light from solar radiation, they are highly absorptive to the long-wave radiation reflected by the Earth, which is often referred to as the “greenhouse effect”, leading to global warming. The consequences of global warming will redistribute global precipitation, melt glaciers and frozen soil, and increase sea levels, which will harm the balance of natural ecosystems and result in climate change and threaten human food supply and living conditions.
The specific cause of the global warming trend is that people incinerate fossil minerals to generate energy or there is deforestation that injects CO2 into the Earth’s atmosphere. The Intergovernmental Panel on Climate Change predicts that by the climate model, until 2100, global temperature estimates are expected to increase by approximately 1.4-5.8 degrees Celsius (2.5-10.4 degrees Fahrenheit). According to this forecast, global temperatures will experience dramatic changes that have never been seen in the past 10,000 years, which will have a potentially significant impact on the global environment. There are two main reasons for global climate change: human and natural reasons, among which humans account for the main reason.
