Since ancient times human beings
up to now, human beings have always experienced growth in each time period that
was spent. Human civilization now has undergone a lot of progress. During
development, the man living with dependent on farming and agriculture. Through
the life orientation, human beings are always trying to maintain and preserve
its environment as well as possible with the aim to maintain the survival of
mankind. Humans now have experienced times of the industrial revolution that
took the life of the industrial field. Using the orientation of the
agricultural world, life seemed to decline slowly. The value of human life has
undergone a change, especially in human interaction with the environment.
The changes that happen to
produce a positive impact or negative. One of the effects of the industrial
revolution that has taken place and continues on the present in lives and human
civilization is its impact to the environment around the man himself. The
expansion of work done by the perpetrators of industries such as the
construction of factories and manufacturing production with large capacity with
override concern for the impact to the environment is slowly but surely have
resulted in negligence will ultimately be detrimental to the environment human
habitation and life.Environmental experts have found indication of impacts to
the environment and the world's largest globally due to the efforts of industry
does and has been growing rapidly at this time. This is the negative impact of
warming in the world and is often referred to as Global Warming. However, the
problem of Global Warming as an environmental issue of this truth is still
debated by some who think Global Warming is the reason which was created to
restrict the pace of industrial development. Although there is still debate
about the correctness of State Global Warming among the experts of the
environment, the problem of Global Warming is not diungkiri to be researched
and examined further for the sake of the continuity of human life.
GLOBAL WARMING
Global warming or Global Warming
is the process of increasing the average temperature of the atmosphere, oceans,
and landmasses of Earth.
The global average temperature at
the Earth's surface has risen 0.74 ± 0.18 ° C (1.33 ± 0.32 ° F) during the last
hundred years. The Intergovernmental Panel on Climate Change (IPCC) concluded
that, "most of the increase in global average temperatures since the
mid-20th century is very likely due to the increased concentration of
greenhouse gases due to human activities". via the greenhouse effect. These basic conclusions have been raised by at
least 30 scientific and academic bodies, including all of the National Academy
of science of the G8 countries. However, there are still some scientists who
disagree with some of the conclusions of the IPCC put forward.
Climate models project that the
reference made by the IPCC shows global surface temperature will increase 1.1
to 6.4 ° C (2.0 to 11.5 ° F) between 1990 and 2100. Difference of estimates was
caused by the use of different scenarios of emissions of greenhouse gases in
the future, as well as models of different climate sensitivities. Although most
of the research focused on the period up to 2100, warming and sea rise is
expected to continue for more than a thousand years, although the level of
greenhouse gas emissions have stabilized.This reflects the magnitude of the
heat capacity of the oceans.
Rising global temperatures are
expected to lead to other changes such as rising sea levels, increasing the
intensity of extreme weather phenomena, as well as change the amount and
pattern of precipitation. The consequences of global warming are another
terpengaruhnya agricultural output, the loss of glaciers, and punahnya the
different types of animals.
The Causes Of Global Warming
1. greenhouse effect
All sources of energy on earth
comes from the Sun. Most of the energy in the shape of shortwave radiation,
including visible light. When this energy is reached the Earth's surface, he
turned from the light into heat that warms the Earth. The surface of the Earth,
will absorb the most heat and reflect it back the rest. Some of this heat takes
the form of long-wave infrared radiation to space. But most of the heat stays
trapped in the Earth's atmosphere due to overwrite the amount of greenhouse
gases include water vapor, carbon dioxide, sulfur dioxide and methane into the
trap this radiation wave. These gases absorb and reflect back the wave
radiation emitted from the Earth and as a result the heat stored in the Earth's
surface. This state occurs continuously resulting in an annual average
temperature of the Earth is increasing.
2. the effect of Feedback
the causes of global warming are
also influenced by feedback processes it generates. An example is the
evaporation of water. In the case of warming due to increasing greenhouse gases
such as CO2, warming initially will cause more widespread water evaporates into
the atmosphere. Because water vapor is itself a greenhouse gas, the warming
will continue and increase the amount of water vapor in the air to achieve an
equilibrium concentration of water vapour. The greenhouse effect it produces is
greater when compared by due to CO2 gas. (Although this feedback increases the
absolute moisture content in the air, relative humidity of air is nearly
constant or even decreases slightly because the air becomes warmed up).[3] this
feedback effect only slowly because CO2 has a long age in the atmosphere.
Another important feedback is the loss of ability to reflect light (albedo) of
ice.[4] when global temperatures increase, ice near the Poles melts with
increasing speed. In conjunction with the melelehnya the ice, land or water
beneath it will open. Both land and water has the ability to reflect light less
when compared to the ice, and as a result it will absorb more solar radiation.
This will add to the warming and cause even more ice melts, it becomes a
continuous cycle.
This Is Some Scene From The
Effects Of Global Warming
1. Fire

effects of global warming. occur in the summer time.
2. Ice Melts
The melting of the ice dikutub in
the temperatures skyrocket rise drastically so it can melt the polar ice caps.
3.
The Surface Of Sea Water Rises
High sea level rise is caused by water ice that has
melted from the direction of the pole.
