Abstract:
Climate Change is the statistically significant variation of
either mean or its variability, persisting for an extended
period of time, typically decades or longer due to
changes of atmospheric composition attributable to
human activities (IPCC, 2001) Factors that may change
the natural rhythm of climate are, oceanic processes
such as ocean currents (/.e, Gulf current), biotic
processes, variations in solar radiation received by earth
(i.e, sunspot activity), plate tectonics and volcanic
eruptions, variations in the earth's orbit, mountain-building, con tin ental d rift and hum an-induced
alterations of the natural world. Of these, the human
induced alteration of the natural world effects are
currently causing global warming, and "climate change"
is often used to describe human-specific impacts such as
changes in greenhouse gas concentration in the
atmosphere. Climate change, particularly global
worming occurs when rate at which energy is received
from the sun to the earth exceed the rate at which it is lost
to the space which determines the equilibrium
temperature and climate of earth. This energy is
distributed around the globe by winds, ocean currents,
and other mechanisms affecting the climates of different
regions.
