The scientific definition of climate includes a very complex interaction between several dynamic systems that leads to a very delicate balance. Antropogenic, or human induced, climate change is a critical issue in science and in the affairs of humankind. The political heat of the debate has masked the scientific aspect of it from the public. Though the target of substantial research, the conclusions of climate change studies remain subject to numerous uncertainties. In this talk we present a very brief review of the basic arguments regarding anthropogenic climate change with particular emphasis on scientific uncertainty.
