Global Warming, Spearman, Grey Correlation Theory.Abstract
In recent years, mankind has experienced the hottest period in its history as greenhouse gas concentrations have increased. As a hot topic for many years, the issue of global warming is gaining more and more attention.By exploring and analyzing the main factors affecting global temperature, we can take targeted measures to improve the global warming situation.In this paper, firstly,by building the ARMA model, we found that the global average temperature is increasing year by year.Secondly, we analyze that latitude and longitude are negatively correlated with global average temperature and time is positively correlated with global temperature by Spearman's correlation coefficient method, and year, CO2, population, forest area, land area, wetland area are all correlated with global temperature by gray correlation theory method, and the gray correlation of year, CO2 and land area is over 0.9.Finally, we give some effective suggestions to improve global warming,such as expanding forest area and reducing carbon emissions.
