climate as the statistical average of weather over a period of time,
such as the 30 year "normals" used by the National Weather
Service. Another way to think of it is that climate is what determines
what crops we plant for a given region and when we plant and harvest
them. Climate includes weather patterns over months, seasons, decades,
centuries. These could include a persistent heatwave or drought. More
technically, climate is defined as the weather conditions resulting
from the mean state of the atmosphere-ocean-land system, often described
in terms of climate normals or average weather conditions.
