Abstract: Report of the Nongovernmental International Panel on Climate Change (NIPCC) is reviewed, which shows completely contradictory position to that of the Intergovernmental Panel on Climate Change (IPCC). It is indicated in the report of NIPCC that nature but not human activity caused global warming. Publication of present paper does not mean the support of the authors to the report of NIPCC. Listen to both sides and you will be enlightened, heed only one side and you will be henighted. Listening to the different voices would be much better than accepting the onesideness in promoting the science of climate change. Finally, comparing with the report of NIPCC, the view-point of "Copenhagen Diagnosis" is introduced, which represents the position of IPCC, and a critical review of the report of NIPCC is given.

Key words: NIPCC, IPCC, global warming
