GLOBAL WARMING
The term ‘Global
Warming’ refers to the rise in the temperature of planet earth which will bring
an end to the mountains old human civilization. The Green house gages including
CFC-11 and CFC- 12 make the earth hotter and hotter by absorbing maximum quantity
of thermal radiation of the sun. These gasses permit the rays of the sun to
penetrate but don’t let the thermal radiations escape from the earth’s
atmosphere once they enter it. This causing what is termed as the Greenhouse
effect which is responsible for the increase in the temperature all over the
world. The rise in temperature disturbs the rain cycle, the ecological balance,
the cycle of seasons etc.
Thus, we have to face frequent floods and
droughts through the world. With the increase in temperature and the melting of
glaciers, even snowfall has reduced its occurrence and intensity. The winter
temperatures are showing a gradual increase. With the warming of the planet
there is also rise in humidity because the rise in temperature has increase the
rate of evaporation. The local governments should work against the emission of
the Greenhouse gages by improving the vehicles, creating awareness among the
people, selling environment-friendly appliances; encourage recycling of paper,
metal and glass etc. Such efforts are needed by the people at the grass-root
level.
Global warming can be best defined as the
increase in the overall warming of our planet, which if not checked will burn
all of us alive in the near future. According to a recent study Green house
gages are the major cause for the increase of the average temperature of earth.
There is a danger of coastal regions drowning due to increase in sea level with
the shrinking of glaciers. Thus there is a grave danger of an entire
civilization becoming extinct in a watery grave. Animals and plants are also
finding it difficult to cope up with these temperature changes.
Species after species of both flora and fauna
might disappear from the face of earth. Not only this, even human life is
getting affected by Global Warming. Epidemics are spreading frequently. There
is heat stress responsible for killing people. Disease like dengue fever,
yellow fever and encephalitis are indirect results of Global Warming. As the
saying goes “It’s never too late”, the government should now try to educate the
people about various kinds of pollution and create public awareness.
People should be involved in helping to reduce
and control pollution. Moreover, punishment should be strictly given in case of
violation of any environmental law so that such people learn a lesion. Until we
all get serious and resolve to make our planet a better place to live in,
humanity stands amidst grave danger of perishing and being destroyed due to the
severe and increase problem of pollution. The need of the day calls each and
every citizen of planet earth to plant trees everywhere.
According to the Human Development Report
(H.D.R) 2007, developed countries should cut their carbon emission at least by
80 %, by the year 2050, with 20 -30 % cuts by 2030, if the earth has to be
saved from the adverse effects of Global Warming. The report also calls for 20
% in carbon emission by fast growing economies like Indian and China. The UN
report says that there is a small window of opportunity in this century for
limiting the global temperature increase to 2 degrees centigrade. If this is
not done, humanity will face a series of climactic changes that will wreak
havoc on the planet. These will include flooding of coastal areas, crop
failures, epidemics, severe water scarcity and increase in natural disasters.
According
to the report, climate change will affect the world’s poor most. Global warming
will initiate droughts and flooding which will destroy the sources of live hood
for poor people in Africa, Asia and South America. The poorer sections will
also be the most prone to health disaster like spread of malaria and diarrhea.
The H.D.R also makes it clear that the rich countries have to take the main
responsibility for controlling emissions.
All living organisms will be burn alive. Yes!
Global warming if not check will bring an end to life on planet earth. Thus
governments all over the world are concerned about the adverse effects of the
rise of the average temperature of planet earth. IN 1992, the earth Summit was
held at Riode Janeiro, Brazil where 150 countries agreed to confront the
problem of Greenhouse gages. In 1997, in Japan, 160 nations signed an agreement
called as Kyoto Protocol. The Protocol calls upon the developed nations to
reduce the emissions of Greenhouse gages up to 50 % by 2012.
Global warming is the increase in average global
temperature due to increase in amount of green house effects in the earth’s
atmosphere. The average global temperature is 15 degree centigrade which is
maintained due to presence of certain gases like Carbon dioxide, methane, water
vapor, nitrous oxide and chlorofluro carbon present with troposphere. The gages
are collectively called heat trapping or green house gages. Lanth’s temperature
is maintained by traditional infer-red (heat) radiation by these Green House
effects which prevent heart from escaping to outer space, so one functionality
comparable to glass panels of a green house which keep carbon dioxide
concentration higher and so higher temperature inside the green house. So the
effect is called Green House effect.
The challenge before us is to reduce Global
warming. Global warming will melt the polarize caps. It is estimated that if
all the ice on the earth melts, about 200 feet of water would be added to the
surface of all oceans. Satellite pictures have shown that the solar ice has
been shrinking by 10 percent per decade since 1980. Due to global warming,
India-Khumba glaciers of Md. Everest has retreated by 5 km since 1953 while sea
ice cover of Arctic Ocean has declined by 6 % from 1978 to 1953.
The time has gone from our hands for debating on
the issue of Global warming. Today the need of the day demand implementation of
measures to decrease Global warming. Some of the measures that may help to
check global warming are (a) Control of population growth by decreasing the
birth rate (b) Afforestation (Planting more tress on new areas) (c)
Deforestation reversal by reforestation (d) Reduction in the use of chlorofloro
carbons (e) Shift from coal to natural gas on electricity as energy resource
(f) To trap and use methane as a fuel. (g) More use of non-conventional source
of energy like wind power and solar energy. Automobiles should be made more
fuel efficient and less taking on the environment.
The global
warming theory is the liberal that the world is becoming dangerously warmer
due to the emission of greenhouse gases, such as carbon dioxide, methane, and
nitrous oxide. Liberals have used the theory of man-made global warming to seek rationing by
government of life-saving energy production and consumption. The most accurate data from satellites confirms that
there has been virtually no global warming since 1998. The media insist
otherwise by publicizing local variations in unscientific surface
thermometers,when the more scientific atmospheric temperature does not show
such an increase.
Moreover, natural periods of global warming and
global cooling are expected to occur regardless of human activity, and not long
ago liberals were demanding more government control to combat an alleged
cooling in temperatures, with some scientists warning of a possible ice age. Global cooling, a theory that predates global warming,
obviously occurs naturally many times throughout Earth's geological history. The
ease of refutation of anthropogenic global cooling claims foretells the
eventual fate of the current global warming hysteria.
Many political activists use the term
"global warming" to refer to anthropogenic
global warming theory (AGW), which asserts that human activity such as spewing "greenhouse gases" is causing an increase in temperature and
is more significant than natural causes and cycles. The AGW theory is supported
by left-leaning political parties, as well as a majority of sovereign states,
national agencies, and an intergovernmental panel (see IPCC). The reality is that
there is no immediate global crisis, and even dire warnings by the UN's Intergovernmental
Panel on Climate Change (IPCC) admit that significant effects will not be manifested for
at least 100 years. Predictions made by climate models publicized by the IPCC have not come to pass in
recent years. Many scientists, such as Hal Lewis, have decried global warming
as a conspiracy for the purpose of securing trillions of dollars in grant
money.
In November 2009, emails were disclosed that
implicated a wrongful manipulation and concealment of data by scientists who
have insisted that there is dangerous man-made global warming. Prior to ClimateGate, both the Republican and Democratic party
Platforms in 2008 suggested that global warming is happening, that it is caused
by human activity, and that it should be counteracted. For example, in 2007,
the Republican presidential candidate Senator John McCain called global warming "an issue we can no
longer afford to ignore". In 2010, an independent analysis cleared the
scientists involved of any wrongdoing as
scientists, but remarked upon their omissions as data-presenters.
Accordingly, the effects of the scandal still linger.
