Prediction Of Global Temperature Based on ARIMA And GM Model

Abstract

Global temperatures have risen rapidly in recent decades .In order to find the rising trend of global temperature, this paper establishes ARIMA model and GM model to fit the past temperature changes and predict the future temperature trend. The results showed that the global average temperature will reach 23.55 °C by 2050. Then through the evaluation index SSE, it is judged that the ARIMA ( 0,1,2 ) model hasthe best prediction effect.
