WHAT IS GLOBAL
WARMING - GLOBAL WARMING ISSUES
Articles About Global Warming - Global Warming
or if in the Indonesian language is called global warming is a process of
rising temperatures that occur in the atmosphere, ocean or on land earth.
According to several studies have been conducted, the average air temperature
at the surface of the Earth during the last 100 years has risen 0.74 ° C ± 0:18
(1:33 ± 0:32 ° F).

CAUSE OF GLOBAL
WARMING
There are some that become the cause of global
warming on earth. Humans, including one of the causes of global warming /
global warming. Why humans are also one of the causes of global warming? The
answer is because humans have increased the amount of carbon dioxide released
into the atmosphere when they burn fossil fuels, solid waste, and wood to heat
buildings, power vehicles and generate electricity. Why, what is the connection
between humans and carbon dioxide? Humans inhale oxygen during breathing and
releasing it in the form of carbon dioxide. While carbon dioxide is one of the
factors that cause greenhouse gases is the cause of Global Warming that we
shall discuss below. Therefore we need to plant is to reduce the impact of
Global Warming / Global Warming. Because of herbs / plants can absorb carbon
dioxide as the photosynthesis process. Photosynthesis split carbon dioxide and
release oxygen into the atmosphere and take the carbon atom.
Below we
will explain in detail about Global Warming Causes of Occurrence / Global
Warming that I quote from Wikipedia:
1. Greenhouse
Effect
All energy
sources that exist on Earth comes from the Sun. Most of the energy in the form
of short-wave radiation. When this energy arrives Earth's surface, it turns
into heat that warms the Earth. Earth's surface, will absorb some heat and
reflecting back the rest. Much of this heat is tangible long-wave infrared
radiation into space. But some of the heat remains trapped in Earth's
atmosphere due to accumulated amount of greenhouse gases such as water vapor,
carbon dioxide, sulfur dioxide and methane which trap this radiation. These
gases absorb and reflect radiation emitted wave and consequently the Earth's
heat is stored in the Earth's surface. This situation occurs continuously,
resulting in an annual average temperature of the earth continues to increase.
The greenhouse effect is needed by all living things on earth, because without
it, the planet will be very cold. With an average temperature of 15 ° C (59 °
F), the earth actually has more hot 33 ° C (59 ° F) from the original
temperature, if there is no greenhouse effect the Earth's temperature is only
-18 ° C so that the ice would cover the entire Earth's surface. However, on the
contrary, if these gases in the atmosphere has been excessive, will cause
global warming.
2. Feedback effects
Causes of
global warming are also influenced by various feedback processes that result.
An example is the evaporation of water. In the case of warming due to
increasing greenhouse gases such as CO2, warming will initially lead to more
amount of water that evaporates into the atmosphere. Because water vapor is
itself a greenhouse gas, warming will continue and increase the amount of water
vapor in the air until it reaches an equilibrium concentration of water vapor.
The resulting greenhouse effect is greater than the effect of CO2 alone. This
feedback effect only gradually because CO2 has a long age in the
atmosphere.Feedback effects due to the influence of clouds is the object of
current research. When viewed from below, clouds will reflect infrared radiation
back to the surface, thereby increasing the heating effect. In contrast when
viewed from above, clouds will reflect sunlight and infrared radiation to
space, thereby increasing the cooling effect. Whether the net effect produce
heating or cooling depending on some specific details such as the type and
height of these clouds.Another important feedback is the loss of the ability to
reflect light (albedo) of ice. As global temperatures increase, ice near the
poles melts at an ever increasing. Along with the melting of the ice, land or
water below it will open. Both land and water has the ability to reflect light
much less when compared to the ice, and consequently will absorb more solar
radiation. This will increase the heating and causing even more ice melts, it
becomes a continuous cycle.Positive feedback due to release of CO2 and CH4 from
the softening of frozen ground (permafrost) are other mechanisms that
contribute to warming. In addition, the melting ice will also cause release of
CH4 are also positive feedback.The ability of oceans to absorb carbon will also
be reduced if it warms up, this is caused by reduced levels of nutrients in the
zone and limit the growth of diatoms Mesopelagic than phytoplankton is low
carbon sinks.
3. Variation of
the Sun
There is a
hypothesis which states that the variation of the Sun, with a possibility
reinforced by feedback from the clouds, can contribute to warming. Difference
between the heating mechanism is due to the greenhouse effect is the increased
activity of the Sun would heat the stratosphere reverse the greenhouse effect
cools the stratosphere. There is some research that states that the
contribution of the Sun may have been overlooked in global warming. Two
scientists from Duke University estimated that the Sun may have contributed to
45-50% increase in average global temperature over the period 1900-2000, and
about 25-35% between 1980 and 2000. Stott and colleagues suggests that climate
models are used as guidelines now make exaggerated estimates of the effects of
greenhouse gases compared with the influence of the sun, they also suggest that
the cooling effects of volcanic dust and sulfate aerosols have also been
underestimated. Nevertheless, they concluded that by increasing the sensitivity
of climate to influence sun though, most of the warming that has occurred in
recent decades is caused by greenhouse gases. In 2006, a team of scientists
from the United States, Germany and Switzerland stated that they did not find
any increase in the level of "explanation" of the Sun in a thousand
years. Solar cycle only a small increase of 0.07% in the "statement"
for 30 years. This effect is too small to contribute to global warming. A study
by Lockwood and Fröhlich found no relation between global warming and solar
variability since 1985, both through the variation of solar output or
variations in cosmic rays.

EFFECTS OF GLOBAL
WARMING / DANGER GLOBAL WARMING
Clean water
is scarce (only 20% of the world that can get it). More frequent storms, new
diseases emerge, we have lost more than 1000 species in a short time, the polar
ice melts and sea levels rise, and many more ..

HOW GLOBAL
WARMING ERADICATE
Turn off the
electricity. (when not in use, do not leave electronic equipment on standby.
Unplug phone chargers. handful of outlets. Although electricity is not carbon
emissions, electricity generation using fossil fuel emissions a major
contributor). Replace light bulb (CFL all types, according to electric power.
Although the price is rather expensive, is more power-efficient light and
durable). Clean light (dust can reduce light levels up to 5%). If forced to use
the AC (close doors and windows for air conditioning is on. Set the temperature
is sufficiently cool, around 21-24o C). Use a timer (for AC, microwave, oven,
magic jar, etc.). Switch the engine waste heat air conditioner to operate
water-heater. Planting trees in your neighborhood. Drying clothes outside. Wind
and solar heat is better than using the machine (dryer) a lot of carbon
emissions. Use public transportation (to reduce air pollution). Efficient use
of paper (raw materials derived from wood). Say no to plastic. Almost all
plastic waste produces harmful gases when burned. Or you can also help collect
them for recycling back. Spread the word to the people around you, so that they
are participating in saving the planet.

GLOBAL WARMING IN
INDONESIA
The impact of global warming / global warming
in Indonesia include the change of seasons in which the dry season becomes
longer, causing crop failures, water crisis and forest fires. Another effect is
the loss of many species of flora and fauna, especially in Indonesia which has
a variety of species such as coral bleaching of 30 percent or as much as 90-95
percent of coral died in the Thousand Islands due to rising sea temperatures.
In addition, the study of the Meteorology and Geophysics Agency said in
February 2007 was a period with high rainfall intensity during the last 30
years in Indonesia. This indicates that climate change caused by global
warming. Indonesia is located on the equator, is the very first country that
will feel the impact of climate change. The impact has been felt that in 1998
became the year with the hottest temperatures and increasing in subsequent
years. 2070 is estimated at about 800 thousand homes are located on the coast
had to be moved and as many as 2,000 of 18 thousand islands in Indonesia will
be submerged due to rising sea water.
