Abstract: This paper studies the multifractality of the time series of atmospheric CO₂ concentration using the MFDFA methodology. The data of the atmospheric CO₂ recorded from Jubany Station, (Antarctica) during the period 1994-2009 was analysed. The data was further divided to subsets of four years and the analysis was repeated. The results show that the complete set reveals more complex pattern than subsets in most of the cases. The degree of multifractality and degree of correlation does not vary appreciably in recent past. However a low value of suggests that the atmospheric CO₂ concentration is expected to increase at a higher rate in the future.
