There are five dimensions to be considered in the study or prediction of weather or climate: longitude, latitude, altitude, time and the weather or climate attributes of concern. Longitude, latitude and altitude define the space where weather/climate events take place. Time plays a multifunctional role, being the basis for determining the variables to be collected, the data desired, physical laws of relevance, and time steps of integration. This paper is an attempt to theoretically sort out the sections in the time continuum from minutes to many years and in the spatial continuum from a few kilometers to hundreds of kilometers, that are relevant to the issue of CO2-induced climate change. 19 refs.
