The close attention has been paid to the climatic change for its important influence on economy and society. Now, the warming of the global climate for the last one hundred years is one of the hot topics in the studies of the climatic change.56'7 It is generally acknowledged that the increasing of greenhouse gases, such as GO2, which enhanced the greenhouse effect, is responsible for the warming of the global climate in the 20th century, especially in the 1980s. In this paper, the global warming is reexamined using of the wavelet transform "microscope". Wavelet analysis is a mathematical technique introduced recently for seismic data and acoustic signals.4 It provides a two— dimensional unfolding of one-dimensional signals, resovling both the time and frequency as independent variable.
