Global
warming is defined as an increase in the average temperature of the
Earth’s surface.
Causes
of global warming: Global
warming occurs as a result of the increased concentration of
greenhouse gases in the atmosphere. Greenhouse gases include carbon
dioxide, methane, and water vapour. These gases trap solar radiations
released back by the Earth. This helps in keeping our planet warm and
thus, helps in human survival. However, an increase in the amount of
greenhouse gases can lead to an excessive increase in the Earth’s
temperature, leading to global warming. Global
warming is a result of industrialization, burning of fossil fuels,
and deforestation.
Effects
of global warming: Global warming is
defined as an increase in the average temperature of the Earth’s
surface. It has been observed that in the past three decades,
the average temperature of the Earth has
increased by 0.6ºC. As a result, the natural water cycle has
been disturbed resulting in changes in the pattern of rainfall. It
also changes the amount of rain water. Also, it results in the
melting of Polar ice caps and mountain glaciers, which has caused a
rise in the sea level, leading to the inundation of coastal regions.
Control
measures for preventing global warming:
(i) Reducing
the use of fossil fuels
(ii) Use
of bio-fuels
(iii) Improving
energy efficiency
(iv) Use
of renewable source of energy such as CNG etc.
(v) Reforestation.
(vii) Recycling
of materials
