Greenhouse Effect and its
relationship with Global warming
house is a natural
phenomenon that keeps the earth’s atmosphere warm.
phenomenon, the temperature of the earth would become too cold for living
beings to survive.
The greenhouse gases (CO2, methane, etc.) absorb the heat of sun and the earth and emit
it back to the earth’s surface.
Thus, these gases
prevent a part of heat rays from escaping into atmosphere.
This cycle is repeated
many times to maintain the earth’s temperature to an optimum 15ºC.
The concentration of
these gases has increased due to increased industrialization, increase in
number of automobiles etc, leading to the heating up of the earth’s surface (global warming).
· This has increased the
overall temperature of the earth, resulting in changes in the earth’s climate.
During the last century, the temperature of earth has increased by 0.6ºC.
This increase in
temperature is ultimately believed to cause the melting of polar ice caps, rise
in the sea level, and submerging of the coastal areas.
Greenhouse effect can
be controlled by reducing the use of fossil fuels, which produce greenhouse
gases on burning, afforestation, efficient energy usage, etc.
