The climate and yield used was for a period of 20 years between 1998 to 2017. Descriptive and inferential methods of research were utilized. The rice production in Pampanga showed an increasing trend within the 20 year period. The irrigated rice comprised 97 of the total rice yield while the remaining 3 came from rainfed rice. The correlation of rice yield vs. rainfall and temperature was also examined. It was found out that there is a no significant relationship between rice yield and temperature. While the relationship of rain fall and rice yield is inverse and significant. Taking into account the monthly averages of rainfall and temperature as well as the climatic needs of the different stages of development of rice a new cropping calendar was proposed. The current cropping calendar is proposed to be moved one month forward so that the ripening phase which is susceptible to excess rainfall be moved to a month where less amount of rain is expected. The results of this research will be communicated to the farmers of Pampanga once approved and examined by the concern government agencies. Introduction Climate change is a broad range of global phenomena which is primarily and mostly created by burning fossil fuels which add heat-trapping gases to the Earth s atmosphere NASA 2016 . It is one of the biggest challenges facing humanity in the 21st century. The Intergovernmental Panel on Climate Change IPCC predicted that throughout the .
