摘要：Global warming has been a heated topic in recent decades and it is shown that the average temperature of U.S. has been increasing since 1901 and more quickly from 1970s. However the data reveals that on state level a different temperature changing pattern exist and some area might experience cooling during coming decades. This paper uses SVAR model to analyze the different temperature trends of two representative states Georgia and California and identifies the possible factors and causes of this differences.
