To control weather over large areas of the world would seem,at this time,to be impossible.
Howerever,man has been highly successful in his attempts to modify the weather on a very samll scale.He has developed microclimates inside and outside homes and offices.
Micro means small,and microclimate refers to the climate conditions over a small area.There are many things that might cause the climate in a small area to be different from the general climate of the region in which it is located.
For example,within cities there might be smaller areas where the climate is different.The microclimate in the yard of one home may be quite different from the one in the yard across the street.It is the number of trees and their position in a yard that affect the microclimate.One could probably name many other things that would change the microclimate of a yard.
Heaters and air-conditioners now in houses and automobiles are good examples of the methods man uses to control microclimates.A completely air-conditioned house is one in which the microclimate can be controlled to suit man's comfort.
