Earth has become
warmer about 1 º F (0.5 º C) from 100 years ago. But why? And how? Actually
science experts also do not know for sure. Earth may be a naturally warm, but
many climate experts who believe that human actions have helped to make the
Earth becomes warmer.
** GREENHOUSE EFFECT **
The experts have
agreed that the greenhouse effect caused by the increasing number of greenhouse
gases (GHG) in the atmosphere which causes heat energy that should be released
into the earth's outer atmosphere is reflected back to the surface and cause
the Earth's surface temperature becomes hotter.
** GREENHOUSE GAS: **
There are several
gas diatmosfir that serves as a \ 'catcher \' solar thermal energy. Without
these gases, heat will be lost to space and Earth's average temperature can be
60 º F (33 º C) cooler. Because of its function as guardian of the warmth of
the Earth, these gases are then referred to as the Greenhouse Gas (GHG). Which
include among others: Carbon Dioxide (CO2), Nitrous-Oxide (NO2) and methane
(CH4).
** GREENHOUSE: **
Have you ever seen
a greenhouse? Greenhouse typically in the form of a small house which consists
entirely of glass and built to grow various crops, especially winter soften.
How does a greenhouse work? Glass panels allow incoming sunlight but keep it
causes heat energy is lost into the air. For convenience, imagine if you get
into the car parked under the sun, hot joknya not it? Well, as well as existing
plants in the greenhouse, which retained heat causes plants to survive in the
winter.
** GHG AND ATMOSPHERIC: **
The atmosphere is
all around us, he is the air we breathe. Greenhouse gases in the atmosphere
similar function with glass panels in a greenhouse. Sunlight enters the Earth's
atmosphere, through the layer of greenhouse gases. After reaching the entire
surface of the earth, soil, water and other ecosystems that absorb energy from
light. Once absorbed, this energy will be re-emitted into the atmosphere. Much
energy is returned to the air, but most caught by greenhouse gases in the
atmosphere causing the Earth to be warmer.
Greenhouse effect
plays an important role in human survival on Earth. Without those effects, the
Earth would be too cold to be occupied. But on the contrary, if the effect is
too strong, the Earth will be warmer than it should and will arise new problems
for human life, plants, and animals.
** CLIMATE CHANGE **
Climate is average
weather events in a specified region in the long term. For example, there is
the possibility of a winter day in New York, United States, there has been a
sunny day and warm, but the average weather - climate-tells us that winter in
New York generally will be cold and full of snow and rain . Climate change
represents a change in the weather over the long term, could be warmer or
colder. Rainfall or snow on average per year can be increased or decreased.
** WEATHER **
Weather portray
anything that happens in nature at a certain time in a certain place. Weather
is something natural phenomena terhadi from minute to minute. Weather can
change dramatically in a short time. For example, could have been raining for
an hour and suddenly the sky was clear and bright. Weather is what we hear on
the television news every night. Which included daily changes in weather is the
humidity, barometric pressure, temperature and wind conditions at a particular
location. Now, tell me, how the weather at your place today?
** CLIMATE **
Climate describes
the total weather that occurred during a specific period in a year at a certain
place, Which includes average weather conditions, season (cold, hot, spring,
fall, rain, and drought), and special natural phenomena (such as tornadoes and
floods). Climate tells us how to live in certain areas. Rainy city of Bogor,
Jakarta, hot, cool and Bandung. So, how the climate where you live?
** GLOBAL WARMING **
Global warming is a
term that indicates an increase in average temperature of the Earth, which then
causes changes in climate. A warmer Earth may lead to changes in rain cycles,
sea level rise, and a variety of impacts on plants, wildlife, and humans. When
scientists talk about the problems of climate change, which became the center
of attention is global warming caused by human activities.
It may be difficult
to imagine how humans can cause changes in climate on Earth. However, experts
agree that the act of men that spurred the large amount of greenhouse gases
released into the atmosphere and causing Earth becomes hotter.
Formerly, all the
climate change runs naturally. But with the Industrial Revolution, humans began
to change the climate and environment in which they live through the actions of
agricultural and industrial. The Industrial Revolution was a time when humans
began to use machines to simplify their lives. This revolution began about 200
years ago and change human lifestyles. Previously, people only took off a
little gas into the atmosphere, but this time with \ 'help \' population
growth, fossil fuel burning and deforestation, humans affect changes in
atmospheric gas composition.
Since the
Industrial Revolution, the need for energy to run the engine continues to rise.
Several types of energy, such as the energy you need comes from the foods you
eat. But other energy, such as the energy used to run cars and most of the
energy for lighting and heating homes, comes from fuels like coal and oil, or
more commonly known as fossil fuels because it occurs from the decay of fossils
of living creatures. Burning these fossil fuels releases greenhouse gases into
the atmosphere.
** WHEN WE RELEASE GREENHOUSE GASES INTO THE AIR? **
When you:
- Watch TV
- AC Install
- Lamp lit
- Use Hair Dryer
- Car driving
- Playing Video
Games
- Lit Radio
- Clothes Washing
or Drying with the machinery
- Using Microwave /
Oven
You've helped to
release greenhouse gases into the air. Why? Because every time you do these
things, you need electricity, and electricity generated by power plants - power
plants - most of which use coal and petroleum. Once again, burning coal and oil
produces greenhouse gases.
Other things that
cause us to help to release greenhouse gases into the air:
Throw garbage into
the landfill waste produces methane. Methane is also produced from animal waste
are kept to supply the needs of dairy and meat (like beef) and also from coal
mining; Driving a car; Using / buying
goods produced in factories because their production processes release
greenhouse gases into the air.
** DID WE CAN HELP PREVENT GLOBAL WARMING? **
Of course. If we
wanted to try, each person can carry out their part in helping to prevent
global warming. No one said that driving a car or use electricity is the wrong
activities. We just have to be more clever in the implement. Some people reduce
energy usage by carpooling or use of the car together. For example, four people
can stay in one same car different than driving four cars to go to the same
place.
The following are
things that are easy but it can make you participate in maintaining the Earth
became a better place to live!
- Read
Learning about the
environment is very important. There are many books you can read. For starters,
ask the teacher or library staff to give the title of the book can be read. Or
with the splendor of the internet, it's worth exploring your virtual nature to
look for sites that provide information about the environment and climate
change.
- Efficient Use of Electricity
Turn off lights,
televisions, and computers when you use it selasai.
Rise Bike, Bus, and
Walking
With the occasional
bus, ride a bike, or walking, you've save the use of fossil energy.
- Talking to Family and Friends
Talking to family
and friends about global warming. Let them know what you have learned.
- Tree Planting
Planting a tree at
home and school is a fun activity and one way to reduce the bail of greenhouse
gases. Trees absorb CO2 from the air.
(This is against
the WWF \ 's campaign - anti-carbon sink - so it May be excluded in our
campaign to school children - ed.)
- Recycling
Recycle cans,
bottles, plastic bags, and newspapers. When you recycle, you reduce the amount
of waste dumped in a landfill and you help the rescue of natural resources,
such as trees, petroleum, and metal materials such as aluminum.
- When shopping, buy
environmentally friendly goods One way to reduce the release of greenhouse
gases into the atmosphere is to buy energy-efficient products, such as
automobiles, electronics and lighting.
- Buying products that can be recycled? Look for products that have a recycling mark - three arrows forming a
cycle. Prokus that can be recycled normally made from objects that have been
used. Generally to create a recycled product that is used less energy than new
products. Less energy used, the better.
ENERGY STAR ®
Some objects, such as computers, TV, Stereo, and VCR label that read \ "Energy
\" with a picture of a star. Products with the ENERGY STAR ® label are
made to save energy. Buying this product will help preserve the environment.
