Weather is immediate

Today's temperature, wind and precipitation are weather.

Climate summarizes patterns

A climate description includes averages, ranges, extremes and seasonal behaviour over long periods.

One event does not define climate

A hot day or cold week is a data point within a much larger record.

Climate shapes probabilities

Long-term change alters the background conditions in which individual weather events occur.
