    Abstract

    The fourth IPCC (UN Intergovernmental Panel on Climate Change) assessment report-AR4 in 2007, insisted that the rise of observed earth's average temperature over the past 50 years was very likely (90%) caused by human activities, among which the increasing of greenhouse gases emissions by human being is the main factor.By analyzing the geological records in this study, we found that the fluctuation of CO₂ concentration was the result, but not the cause of climate changes instead, and CO₂ concentration was varying according to air temperature.During the historical period human being has released much CO₂ into the atmosphere.At the same time, the temperature also increased, both of which might be coincident.The theory that the global warming was due to the releasing of CO₂ cannot explain the fact that temperature decrease during some periods of modern human time.Comparing to the long term climate change, we can see that modern global warming is just a warm period within the long-time climatic fluctuation, showing that the global warming has no connection to the concentration of CO2.It could be wrong to ignore natural factors and simply attribute the global warming to human activities.
