Abstract: The two different viewpoints on climatic change reflect two aspects of natural climatic cnange and human activity influence. Human activity influence on climate is mainly temperature-increasing effect(caused by increase of CO₂ content in atmosphere). Cold and warm trends reflected by the climatic changes with time are different. Human activity influence only superimposes the trends, retarding, intensifying of even controlling climatic changes Before the twenty first century climatic change won’t be controlled by human activity influence, but still by natural climiate a change processes.
