Global warming

Global warming refers to the rise of the climate of the earth's atmosphere and the oceans due to the greenhouse effect. Between 1906 and 2005, the global average temperature of the atmosphere near the ground increased by 0.74 degrees Celsius. In general, the scientific community has found that the rate of observable climate change over the past 50 years is twice that of the past 100 years, so it is inferred that climate change in this period is driven by human activities. The heat caused by the temperature rise will provide a huge kinetic energy for the air and the ocean, resulting in large typhoons, hurricanes, tsunamis and other disasters. The rising temperature will result in Glacier melting and sea level rise which cause the coastal ecological environment disaster.

Global warming is a nature-related phenomenon. Human activities like burning fossil fuels, such as oil, coal, etc., deforestation and incineration will produce a lot of carbon dioxide, or greenhouse gases. These greenhouse gases can penetrate through the visible light from the solar radiation, absorbing the long-wave radiation from the earth and the infrared from the ground. It results in the rise of the Earth's temperature rise and facilitating the greenhouse effect. When the greenhouse effect continues to accumulate, it results in the imbalance of ground gas system absorption and emission of energy. The energy constantly accumulates, resulting in rising temperatures and global warming. Deforestation, land reduction and other land use changes have changed indirectly in the atmosphere. The increase in the concentration of greenhouse gases can also lead to global warming.

Due to the increase in the population, the annual emissions of carbon dioxide produced by human activities alone directly leads to the increase of the atmospheric carbon dioxide. It directly affects the Earth's surface climate change. Mineral combustion emission caused by electric energy consumption is also one of the main reasons for the global warming.

The growing environmental pollution has become a major global problem, but also one of the major factors leading to global warming. In the 21st century, research on global climate change has clearly pointed out that the temperature of the Earth's surface has risen since the end of the last century.

Sea level changes are rising. According to the experts’ predict ion, in the middle of the next century, the sea level may rise 50cm. If there are no measures taken, it will

directly lead to the destruction of fresh water resources and pollution and other adverse consequences. In addition, a large number of toxic chemical wastes and solid wastes produced by human activities continuously discharge into the sea. The major leaking oil events in ocean and the destruction of the ecological environment in coastal areas caused by human activities are the main factors that cause the destruction of the ecological environment of sea. The toxic chemicals not only pose a serious threat to human survival, but also to the ecological environment of the Earth's surface.

Human activities cause serious damage to the land due to excessive deforestation, agricultural production and grazing, resulting in large-scale floods and dust storms which cause significant economic losses to the society and worsening the ecological environment.
