Climate is the general state of the atmosphere over a long period of time. Whereas weather is the expression of day conditions, climate is a composite of averages and extremes during a specified number of years.
The element of climate change through time as well as from place to place. Indirect evidence of climatig trends in the distant past is reveated in fossils, lake and ocean beds, peat bogs, glacial deposits, and soils. Widths of annual growth rings in trees correlate with temperature and rainfull fluctuations, especially along the drier margins of fivests, and fossil trees provide records of dramatic climatic events in the past.
Human activity has the potential of affecting large scale climate patterns through the introduction of materials into the atmosphere and the depletion of forest cover. Scientists now clearly recognize that the greenhouse effect, is being enhanced by human activities.
