Climate change is any significant long-term change in the statistical

properties (principally it is mean and spread) of meteorological

variables of a region (or the whole Earth) over a significant period,

regardless of cause. All the theories of climate change attempt to

account for variations in the amount of solar energy received by the

earth and the spatial and temporal distribution of the energy over

time [1-5]. It has been noted also that sector-wise, the combustion

of fossil fuels is the main source of carbon dioxide emission,

followed by deforestation and land clearance for agriculture [2].

In the last decades, researches have shown that man can influence

climate change through the following: a) alteration in the albedo

of the earth surface as a result of deforestation, land clearing, for

cultivation or construction and animal grazing; b) Increase in CO2

content of the atmosphere as a result of bush burning and burning

of fossil fuels through transportation such as coal, gas, oil etc.; c)

Interface and interference with ozone layer by pollution deriving

from human activities.
