GLOBAL
WARMING
Global warming is An increase in the average
temperature of the earth surface Resulting from increased the amount of
greenhouse gas emissions in the atmosphere. The process of increasing the
presence of an average temperature of the atmosphere, the sea and the dry land
earth. Global warming would be followed by climate change. As the increasing
the rainfall in several parts of the world So as to cause flooding and erosion.
While, in another hemisphere Will experience dry season prolonged caused the
temperature increase.
The global average temperature on the surface of the
earth has risen 0.74 ± 0.18 °C (1.33 ± 0.32 °F) During the last hundred years.
Intergovernmental Panel on Climate Change (IPCC) concluded that, “Most of the
increase in the average global temperature since the middle of the 20th century
Most likely caused by an increase in the concentration of Greenhouse gases due
to human activity” Through the greenhouse effect. Conclusion this base has been
mentioned by at least 30 a body of scientific And academic, Including all
national academy of sciences of the G8 nations. However, there are still some
scientists who did not agree With some conclusions mentioned by the IPCC.
Climate models used as the reference by ipcc
projects Show global surface temperatures will increase 1.1 until 6.4 °C (2.0
until 11.5 °F) Between
1990 and 2100. The differences in the forecast was
caused by the use of Different
scenarios regarding emissions of greenhouse gases in the future, As well as the sensitivity of the
climate models different.
Although
most research focused on the period until 2100, Heating and the increase in the
face of the waters of the sea Is
expected to continue for more than a thousand years Although the level of greenhouse
gas emission has been stable. This
is reflected from the heat of it.
Increased global temperature is estimated The changes will cause another. Like a rise in the sea level, The phenomenon of increasing
intensity of weather extremes, As
well as changes the number and pattern precipitation. The implications of global warming
the other is terpengaruhnya of agricultural products, The loss of glaciers, and punahnya
different kinds of animals. Global
warming occurs when there is a concentration of certain gases. Known as the greenhouse gases, Who continues to grow up in the air, It is caused by the humans, industrial activity, particularly CO2 and
chlorofluorocarbon. Which is mainly carbon
dioxide, That is generally produced by the
use of coal, Petroleum,
Gases and deforestation and forest burning.
With the increase in the amount of carbon dioxide in
the air, A green plant that serves To neutralize carbon dioxide no
longer able to work. The
amount of forest that is in the whole world the shrinking Because used to economic reasons. A style of human life lead to the
use of fossil fuels continues to rise. The use of fossil fuels really have any
negative impact At
some of the environment.
As
has been mentioned above that The
result of burning fossil fuels in the form of carbon dioxide In the form of a poison that can
damage the environment.
Carbon dioxide is destroy ozone The main task of ozone protect us
from ultraviolet rays And
solar radiation other dangerous.
In
addition to this problem, fossil fuels such as petroleum, Coal and others. To take a fossil fuel needs process
of exploration. Fossil
fuels often find myself in the forest
In
which to do the digging must open and destroy forest.
Nitric acid produced by a vehicle and industrial
emissions, While
methane emissions caused by the activity of industry and agriculture. Chlorofluorocarbon CFCs Destructive to the ozone layer As also greenhouse gases causing
global warming, But
now removed in the montreal protocol.
Carbon
dioxide, chlorofluorocarbons, methane, Nitric acid is the gases pollution
that accumulates in the air And
filtering more heat from the sun.
While
the ocean and vegetation captured so much co2, His ability to become “the roof” now excessive due to emission. This means that every year, The number of akumulatif of
greenhouse gases Who is in the air increased And that means speeding up global
warming.
The increase in global temperature changes is
expected to cause any As
sea levels rising, The
intensity of the phenomenon of increasing weather extremes, As well as changes the number and
pattern precipitation.
The
implications of global warming another was affected agricultural products, the loss of gletser, And extinct different
kinds of animals. Some
scientists doubt that it is About
the amount of warming that is expected to happen in the future, And how warming as well as changes
the Will vary from one region to
another. Until
this moment still happens political debate
And
the public in the world about what,
If
there are action must be done to reduce
Or
reverse further warming Or
to adapt to its consequences which there is. Largely of governments of countries
in the world have signed And
ratified Protokol Kyoto, Which leads on emission
reduction of greenhouse gases.
The cause of global warming And serious for the environment
bio-geofisik. (as
melting ice in polar, To
raise the surface of the sea,
The
expansion of the desert sand,
Increased
rain and flooding, the
climate change, Extinct
flora and fauna certain,
Migratory
animals pests and diseases,
etc. While the impact for socioeconomic
activity covering : (a) Function
disorder against coastal areas and coastal town. (b) Function disorder against
infrastructure and facilities like road network, of
seaport and airport. (c) The
settlement of the problem.
(d) The
reduction of agricultural land productivity. (e) Increased risk of cancer and
epidemics.
According to Kompas, (27 April 2007) We might still know many people who
are unaware With
the impact on the dangers of global warming. We are still too indifferent to
respond to the problems And
we can actually make that a generation is coming. Currently
still many people only think about ourselves
Without
considering where we live are nearing this irregular. No more than the man who often
littering, Cutting
down trees with as one pleases,
Turn
on the electricity in vain And
still many other activities are Which
exacerbate the condition on earth our beloved this.
And it turns out the nation that we are placed in
indonesia is this The
state which is a contributor / highest number of contributors to the order of
the number three In
terms of increasing heat in this world.
Because
of the increased carbon dioxide emissions as well as other gasses. Known as the greenhouse gases that
envelop and traps the earth heat.
Greenhouse
gases is the gases in the atmosphere that having the function of As panels of glass in a greenhouse
on duty catch energy heat of the sun so as not detachable wholly into the
atmosphere back.
And also experts say, The earth has already lost the
ability to “cools” himself. Gas produced by the industry, As well as the more scarcity of the
forest as an absorbent carbon, Make hot trapped. Like being trapped in this heat in
an automobile that the glass closed doors of the. You can see some of the global
warming effect. 100
million people in the coastal area will be flooded permukimannya asia, And 4,000 from about 17,500 island
in indonesia will sink.
Both water will not be enough to mankind 25 years
again. The Eternal
ice third (permafrost) in kutup will melt down fully 40 years from now. The surface of water would rise to
approximately 64 metres if a of ice layer in the earth to melt. Fourth 2050 years, 130 million of the
world population threatened starvation, Especially in asia and africa. Fifth year 2080 more
than 100 million people threatened flood every year, And 30 percent of the line of coast
in the world will disappear. Sixth
years 2090 there will be a flood of waters giant in north America, And these can recurring 3-4 years
once. Seventh next 100 years 80 % species
of plants And
animals in the world will be endangered.
According to Tempo.co (JAKARTA,SELASA, 19 MEI 2015 | 04:30 WIB). Unique river means quell global
warming. During this scientist The solution is to reduce global
warming which is the amount of
carbon which is excessive. But it
turns out have nature own mechanisms to overcome the problem, Namely passing a network of river. scientists from Woods Hole Oceanographic Institution in Boston, united states, Successfully identified river role in
reducing the rate of global warming. Research
has already been published in the journal nature may 14 edition 2015. “Act as the circulatory
system in the earth, They
really immersive carbon into the sea and reduce significantly The volume of carbon dioxide that can
come back into the atmosphere in the form of greenhouse gases,” Geokimia experts said, Valier Galy, As quoted from Science Daily, Senin, 18 Mei 2015.
Galy involving two colleagues, Bernhard Peucker-Ehrenbrink and Timothy Eglinton To take samples to 43 system river
that flows across the whole world.
Sample
selection based on the geological conditions, the climate, vegetation, And the environmental pollution
from human beings. Research
result indicates galy noted river capable of carrying 200 megaton Or equivalent 200 million tons of
carbon dioxide into the ocean. That
number,
galy added, Is
still approximately 0.02 percent compared to the total volume of carbon dioxide
is in the atmosphere. “but
the amount of carbon dioxide are disentangle will increase by 20 percent A thousand years until the next,” he added. Galy unravel generally carbon
dioxide (CO2) Converted
to organic carbon through photosynthesis.
But,
the return of carbon in the atmosphere
When
the plant is dying and dissolves on the ground. A
small portion of it and it ended at the Jordan And
drifting on until to sea. Don
Rice, Program Director pada National Science Foundation's Division of Ocean
Sciences, Who
fund institution research galy welcome positive result of the research such. “this study reveals the importance
of The relationship between the volume
of carbon with a cycle of the river,” rice said.
