Abstract/Summary

Nowadays, climate change and its following impacts have influence on human life, society, and natural ecosystems in many regions on a global scale. Based on the datasets of temperature and human activities, this research analyses the temperature variation trend in Nanjing from 1980 to 2020 by linear regression and time series decomposition. In addition, by comparing correlation coefficients and multiple linear regression, this research explores the correlation between changing temperatures and human activities in the past 41 years. The results show that the temperature of Nanjing has had an increasing trend in the past 41 years, and the warming amplitude is the largest in the spring. Also, temperature change has a correlation with some human activities, and the correlation between total energy consumption and temperature is the biggest. Thus, the influence of human activities on climate is really important.
