GLOBAL WARMING
In my
article this time I will discuss about Global Warming. Global warming is defined many experts that
process, causes, impacts / consequences and how to overcome the most important
thing in the study about global warming. We all know the impact is very harmful
to the health of our planet and of course has implications for all the
inhabitants of the earth. First of all let us discuss definition Global
Warming. In General, Global Warming (Global Warming) are events increasing the
average temperature in the layer of the atmosphere and Earth's surface.
According
to various studies, at this moment in Earth's surface temperature has shown a
drastic increase of around 0.6 ° C, which occurred in the last century.
Improvement and looks fairly small, but the impact of global warming are very
big for the Earth and life on Earth. In symptoms or signs of global warming we
can observe and feel. The symptoms of global warming is the turn of a difficult
season we predicted, the frequent occurrence of a tornado, bleached reefs, and
floods and droughts in the region of an unusual experience.
Many
experts who express an opinion about the causes or factors of global warming.
According to the experts that the Earth's surface warming due to increased
greenhouse gases in the atmosphere that trap heat, not only that, there are
many more causes of global warming need to be friends to know in repair and
overcome it.
There are
many causes of global warming: the first is the model of a greenhouse.
Greenhouse became one of the causes of global warming is a greenhouse where the
model both in homes, buildings or places that use the concept of building glass
can reflect light instead of absorbing air and sunlight. So that the impact of
the glass umah concept is very influential on the increase and improvement of
global warming on Earth.
The
second is Wastage in electricity consumption. Electricity is used by everyone,
but many people are not aware of the savings on electricity usage. Various
appeals have been widely driven or carried out, but in reality many people can
not do. Pembororsan electricity still happens everywhere so that electrical
waste could be one contributor to the increasing global warming.
The third
is the use of fuel. Fuel used vehicles in addition to harm the health also
gives the effect of the increase in global warming of the air pollution
produced by each vehicle. The longer the number of users of automobiles and
motorcycles more. It is thus the amount of air pollution that occurs even more.
The
fourth is the air pollution from Industrial and Factory. More and more
industries and plant-growing, more and more global warming. Indeed the plus
side, industry and factory can provide opportunities for the welfare of the
people .Disisi downside losses smoke generated from the industry and very detrimental
to acknowlege earth plant.
The fifth
is deforested rainforest. Many forest fires occurred illegally without
permission from the government. In fact, many forest functions, one of which is
to prevent flooding. Additionally, hutanpun can reduce heat in the earth's
temperature is increasing. A source said that global warming increases by 50%
the cause is CO2, or carbon dioxide. Where the carbon dioxide emissions caused
by damage or forest fires. So deforestation has led to the increase in global warming
of the earth.
Many of
the impacts resulting from the global warming, both positive and negative
effects in a variety of fields. In the field of Agriculture: While CO2 is
essential for plant growth, all agriculture also depends on a steady supply of water,
and climate change tends to destroy supplies through floods and droughts. It
has been suggested that higher latitudes - Siberia, for example - could be
productive due to global warming, but the soil in the Arctic and adjacent
territories is very poor, and the amount of sunlight that reaches the ground in
the summer will not change because it is governed by the tilt of the earth.
Agriculture can also be disturbed by forest fires and changes in seasonal
periodicity, as is already happening, and the change of pasture and water
supplies can affect cattle grazing and domestic prosperity. Increased warming
may also have a greater effect on the countries where the climate is already
near or at the limit temperatures which results in a reduction or crop failure
- in the tropics or sub-Saharan Africa, for example.
In the
field of Health: warmer winters would mean fewer deaths, particularly among
vulnerable groups such as the elderly. However, the same group is also
vulnerable to additional heat, and deaths from the heat wave estimated to be
about five times larger than the prevention of deaths in the winter. It is
widely believed that a warmer climate will encourage migration spread of
diseases caused by insects such as mosquitoes and malaria, which already appeared
in places that have never been seen before.
Impact on
the Liquefaction Pole: While the opening of the Arctic ice-free year-round
between the Atlantic and Pacific oceans will give some commercial benefit, is
far outweighed by the negatives. Adverse effects include loss of polar bear
habitat and increased movement of hazardous ice for shipping. The loss of ice
albedo (reflection of heat), causing the ocean to absorb more heat, is also a
positive feedback; warm waters increase glacier and Greenland ice cap melting,
as well as increasing the temperature of the Arctic tundra, which then releases
methane, a greenhouse gas that is very strong (methane is also released from
the seabed, where it is trapped in ice crystals called clathrates). The melting
of the Antarctic ice sheet is expected to further increase the sea level rise
which no benefit is gained.
impact of
glacial melt Acidification: A matter of considerable concern, seems to be no
benefit on the changing pH of the ocean. This process is caused by the increase
of CO2 is absorbed in water, and may have a severely destabilizing effect on
the entire food chain from melting glaciers samudra.Efek very detrimental to,
the impact of the principle is that millions of people (one-sixth of the world
population) rely on fresh water each persdiaan years from the melting of the
natural springs and regrowth cycle and the water supply - drinking water,
agriculture - the possibility of failure.
Impacts
on Sea Level Rise: Many low-lying parts of the world is to be greatly affected
by rising sea simple. Rice fields flooded with salt water, which damage crops.
Sea water polluting the river because it is mixed with fresh water upstream,
and aquifers become polluted. Given that the IPCC does not enter the water from
the melting of the Greenland and Antarctic ice caps due to uncertainty at that
time, estimates of sea level rise is feared to be much underestimated the scale
of the problem. No benefits are proposed for sea level rise
Impact on
the Environment: The positive effects of climate change could include green
rain forests and enhancement of plant growth in the Amazon, increased
vegetation in northern latitudes and the possibility of an increase in plankton
biomass in some parts of the ocean. Negative responses may include further
growth of oxygen-poor ocean zones, contamination or fresh water saturation,
increase the natural fire events, the spread of vegetation that died because of
the drought, the increased risk of coral extinction, global photoplankton
decline, changes in migration patterns of birds and animals, change periodicity
seasonal, food chain disruptions and species loss.
Impact in
Economics: The economic impact of climate change could be catastrophic, while
there is only very little benefit. Stern report confirms the overall pattern of
economic difficulties, and while a certain number can be contested, because the
costs of climate change far outweigh the costs of prevention. Certain scenarios
projected in the IPCC AR4 report would witness massive migration to countries
flooded lowlands. Disruption of global trade, transport, energy supply and
labor markets, banking and finance, investment and insurance, all would wreak
havoc on the stability of both developed and developing countries. The market
will survive the increased volatility and institutional investors such as
pension funds and insurance companies will experience considerable
difficulties.
To reduce the effect of
global warming which happened, you can try to do: First, choose the energy
saving lamps as the lighting in your house. Energy saving lamps have more
expensive than the general lamps, but the energy which is needed to light up is
smaller than general lamps. Beside of that, this lamp is more durable.
Second, do not forget to
turn off the lamps when they were not in use again. When paying the bills, you
will choose to pay online. This method is more econimal than pay directly. You
can reduce the using paper which is used as noted invoice. You can save the
fuels of your vehicles because you are not need to use your vehicles as when
pay directly.
Third, laptops and
computer are the most things which is used in daily in every house. You should
turn off this device when they are not in use too. And You can choose to do not
use the screen saver to save the energy.
Fourth, when shopping,
you should bring your own bag which is made from the cloth. Avoid to use
plastic bags which is given by the supermarket. Plastic is a material that is
difficult to be processed naturally by the environment. It took hundred years
to make it decomposed.
Fifth, to have friendly
environment, you can use bicycle which will good for your healthy too. In
addition, you must keep the condition of tap in your house in good
condition. From a lot of researches, broken taps can make the a lot of
litter waters wasted in vain. Though, amount of the waters in the Earth is not
much anymore. The last, always try to fill your courtyard with the trees. Tree
can release oxygens which can make the air become fresh.
