To study the long range power-law correlations of the monthly average anomalies over the global, Northern Hemisphere, and China in the recent 140 years,the detrended fluctuation analysis (DFA)method is applied in this paper, which can effectively eliminate noise and possible nonstationarities in the data. The preliminary results show that there exist two different scaling invariant ranges, divided by one crossover in the three temperature series, which may indicate two different underlying physical mechanisms. Fist of all, they all present the positive long range correlations, and the persistence of the global temperature is the strongest, while China weaker than Northern Hemisphere. Secondly, the global and Northern Hemisphere temperatures can nearly behavior like 1/f noise, and China temperature can show behaviors between 1/f noise and Brown noise.
