Why is the weather so bad this year?

Global greenhouse gas emissions lead to global warming. Zhou Lingxi, a researcher at the Atmospheric Composition Observation Service Center of China Meteorological Bureau, said that global warming caused by global greenhouse gas emissions has become an indisputable fact. According to the annual report of the United Nations Intergovernmental Panel on Climate Change (IPCC)200 1, the global average temperature rose by about 0.6℃ in the last century, and the global temperature will rise by 1.6℃ to 5.5℃ by the end of this century, while the sea level will rise by 9 to 85 cm. "However, due to the different effects of emissions in different regions and the uncertain cooling effect caused by volcanic eruption or aerosol, the degree of warming in different regions is not the same, but it is warming in general." At present, it is also at a peak temperature in the history of the earth. Every 6.5438+million years, the earth is a cycle of alternating cold and warm, and the alternating activities are mainly controlled by sunshine, and the sunshine amount of the earth is determined by its orbit and celestial orientation. "From the geological age, it is also at a temperature peak in the history of the earth, so it has superimposed some influences on the basis of global warming."
