Climate of the earth has never been strictly constant in the recent almost 5 billion years. The shorter or longer time changes and fluctuations lead to changes in state of the geographical skin, or, with its more recent and frequent name, the environment. This is why a fourth sub-chapter has been opened in our homepage, for the response to effects of clime given or due by the society, besides the other three ones, i.e. past, present (recent past) and future.

Climatology is embedded into various other sciences, which often leads to discussions even on the concepts of climate, as well as of climate change and fluctuation. Even more frequent and heavy discussions are observed on causes and likelihood of continuation of the present climate change, since the times we are faced to the risk of human-induced climate change. Our homepage does not intend to prefer any view or scientific result against the others in these questions. Nevertheless we still transfer a system of scientific paradigms via selection of the sites and proportions of the views reflected in this selection. But, this is definitely one of the missions of the GEOGRAPHY nEtQUIPMENT to systematise and forward that part of knowledge which has been established by the professional (not by the “official”) science.

Probably, you have already recognised, Dear Reader, that we have a separate entry called Meteorology, as well. It is not our intention, by this, to put our vote to such a classification of sciences. It has a rather practical reason, since there are so many interesting and useful sources in both topics that this may explain the separation, itself. So, materials and referring homepages about the weather, i.e. on definite sequence of the atmospheric states for shorter period of time are arranges into Meteorology. Those questions in which these states correspond to longer period of time, with no special emphasis on their sequence, but treated as statistical ensembles, i.e. to climate, we sorted into Climatology.
