Around the world, in the field of environment, as connected to energy and climate, many common concepts are inherently confusing or have become confused. This paper highlights some of the related contradictions in such very basic concepts as science, climate, climate system, climate change. Historical documents (among others, the birth document of the Consensus in Villach, 1985, and the 1992 UN Framework Convention on Climate Change, UNFCCC) testify, how the climate science has been distorted step-by-step, to the point, where physical reality is no longer the reference for some researchers, but the problem itself. In reality, the physics-oriented climate science can exclusively be regarded as basis for climate science, as far as the rules of sciences are strictly followed. The so-called “science-for-policy” is nothing else than sophistry. Healthy and honest climate science can only be considered beyond any enforced climate change “consensus”.
