5 Caution: what do we mean by “climate” Before we can answer the question, we have to have general agreement on what we mean by “climate.” It is not uncommon to mistake “weather” for “climate” Weather pertains to occurrences from hour to hour, or day to day, in a specific location. Climate pertains to average weather over an extended period of time, in a specific region or on a larger scale. Climate can correspond to averages over a season, year, or century and over a county, state, country, or the globe.
