IMPROVEMENT green house effect
atmospheric temperature changes are generally associated with several factors such as changes in activity of the Sun, or the pattern of rotation of the Earth. However, most scientists believe that global warming is caused mainly by the greenhouse effect. This effect occurs when the bulk of the energy from the sun reaching the Earth kepermukaan not reflected back out into space, malaah otmosfera earth system fails to function properly.
As we find, according to the Wien law, the nature of radiation from an object depends on its temperature. The sun have a surface temperature of 6000 degrees, glowing in the waves seemed terutamamya which is simply the energy in our atmosphere. However, due to Earth's temperature is much lower than the temperature of the Sun, the planet we draw out the energy in the form of infrared radiation. Gases such as carbon-dioxide, methane and nitrous oxide, which is also transparent in the visible wavelength, is opaque in the infrared radiation. Their characteristics are preventing workers from out of the last keangkasa. They absorb the energy to make our atmosphere warm. Most of the solar energy is absorbed by the lower atmosphere, as happened on Venus.
It is probable that the greenhouse effect and global warming, which is accelerating since the 19th century, due to the impact of human activities on the environment. Most of the gas which has the characteristics of the greenhouse effect has been released into the atmosphere through the activities of the modern use of fossil fuels in industry and transport. It can also be caused by certain agricultural activities such as cattle. We expected that carbon-dioxide has increased by 30 percent since the beginning of industrial era, which is a major contribution to aggravate the greenhouse effect.

Global Warming
Earth's average temperature is generally not very stable, but varies with time, as has been proved by analysis of geological layers. Our planet is several tens of degrees colder at 20 000 years ago, the glaciers on the peak days of snow. This temperature change is actually very slow, the temperature change of 0.2 degrees from 1000 until the end of the 19th century.
The fact that the international community is worried about how quickly the temperature changes now, the pace of change has not been seen in the past. Since the end of the 19th century, about one hundred years alone, the average temperature has risen 0.6 degrees. Computer simulation shows that the warming will be faster and the average temperature could rise by 1.4 to 5.8 degrees by the end of the 21st century. This phenomenon we call global warming.
Greenhouse Effect
Atmospheric temperature variations are generally associated with several factors such as changes in activity of the Sun, or the speed of rotation of the Earth. However, most scientists believe that global warming is caused mainly by the greenhouse effect. This effect occurs when the bulk of the energy from the sun reaching the Earth kepermukaan not reflected back out into space, but diserapi by our atmosphere.

The effects of global warming
As has been pointed out, global warming causes glaciers to melt and sea levels rose by several tens of centimeters. The thickness of the ice at the poles also be less. Since the 21st century, this phenomenon is increasing more rapidly, where its effect seems more pronounced, especially the increase in sea levels and extreme weather changes involving precipitation cycles of drought and devastating.
This effect can be felt by people with frequent floods, drought, shortage of drinking water, the spread of malaria, lack of zones of the sea or the scarcity of the island. In the long run, the melting ice in Greenland, which causes sea level rise of 6 meters, we can predict the loss of most of the waterfront zone of the world.
Faced with the threat and the need to address the problem, the international community found to be quite shy. The Kyoto Protocol was negotiated in 1997, seeks to force industrial countries to take the steps necessary to reduce air pollution which aggravate the greenhouse effect. The result of the decision of Russia to participate in this protocol, it will have the opportunity to bring results. However, without the participation of the United States, which is presently the world's largest air pollutants, the results of this protocol usahan somewhat limited. Because of this agreement is not so ambitious, we believe it is not able to effectively slow down global warming. Therefore, the terrible disaster that is threatening.

EARTH WARMING DUE TO NATURAL DISASTERS
Amsterdam # Amsterdam, Netherlands - The number of natural disasters in 2007 rosespectacularly, according to the International Red Cross. When compared with last year,the figure increased 20 percent recorded until October, the number of natural disastersreached more than 400. Each year 270 million people become victims of natural disasters in the world. In previous decades this figure was 240 million. Almost half ofthese natural disasters related to weather, world disasters report issued by the International Red Cross. Climate change summit currently taking place in Bali havereached an agreement about the reduction of CO2 greenhouse gases, which affectweather changes.

Overview of Global Warming, Effects And How To Prevent Global Warming World
We are all both know that global warming is happening. Melaporakn IPCC research that 0.15 to 0.3 o C. If the increase in temperature continues, estimated in 2040 (33 years from now) layer of ice at the poles of the earth will be depleted melt. And if the earth continues to heat up, in 2050 will be a shortage of fresh water, so that famine would be widespread throughout the universe.
The air will be very hot, millions of people fighting over food and water. Breathing the smoke and dust. The houses in coastal areas inundated by sea water. Sea water overflow more and more widespread, so that eventually swallow the whole island.Property will disappear, so does the human soul.
The study conducted scientist at the Center for Coastal and Marine Area Development, Bandung Institute of Technology (2007), was no less horrific.Apparently, the Gulf sea levels rise as high as 0.8 cm in Jakarta. If world temperatures continue to rise, it is predicted, in 2050 in Jakarta daera areas (such as: Kosambi, Penjaringan, and Cilincing) and Bekasi (such as: Muaragembong, Babelan, and Tarumajaya) will be submerged everything.
Well,,, we all already know it ... and some people still try to tell you that this incident actually was going on ... but still not a few people who still do not care. Maybe because we still feel comfortable with the situation now ... can menikamti everything from food, water, air, land sukup to play ball, which is still quite peaceful social, etc ...
Well ... it is ... then how about if 10 years from now, or 20 years, or up to 30 years. I know there will be no significant changes at this time because we all still consider this a normal thing, but I would be very foolish man if I do not keep trying to inform this.
So what can we do?
There are some easy ways that we can do, namely;
1. Turn off the electricity. (When not in use, do not leave electronic equipment on standby. Unplug the phone charger. Handsfree from the socket. Although not emit carbon electricity, PLN's power plants using fossil fuel emissions big contributor.)2. Replace light bulb (the type of CFL, according to electric power. Even though the price is somewhat expensive, this lamp is more efficient electricity and durable).3. Clean light (dust can reduce lighting levels up to 5%).4. If forced to use air conditioning (close doors and windows for air conditioning is on. Set the temperature is cool enough, about 21-24o C).5. Use a timer (to AC, microwave, oven, magic jar, etc.).6. Switch the engine waste heat air conditioner to operate a water-heater.7. Planting trees in your neighborhood.8. Drying clothes outside. The wind and the sun's heat better than using the machine (dryer) which emit lots of carbon.9. Use public transportation (to reduce air pollution).10. Efficient use of paper (raw materials derived from wood).11. Say no to plastic. Almost all plastic waste produces harmful gases when burned.Or you can also help collect them for recycling back.

Livestock: Main Causes of Global Crisis
The only way to avoid the "point of no return" from climate catastrophe is to take actionagainst the main causes of disasters that damage - namely, the production of meat.Currently we have all the evidence, all the information to say so. Livestock industry is aproducer of top greenhouse gas.
The UN report published last year 2006 stating that the livestock industry producesmore greenhouse gas emissions than all transportation combined world-aircraft, trains,cars, motorcycles, etc., simultaneously. [ii]
Latest calculation tells us that the livestock industry is responsible for at least 50% ofglobal warming. [iii]

the true story
There were few precedents for the global sweep of extreme cold and ice that killed dozens in India, paralysed life in Beijing and threatened the Florida orange crop. Chicagoans sheltered from a potentially killer freeze, Paris endured sunny Siberian cold, Italy dug itself out of snowdrifts and Poland counted at least 13 deaths in record low temperatures of about minus 25C (-13F).
The article goes on with example after example demonstrating that we’re currently experiencing the worst winter in many decades.
The reason? Global warming, of course:
Guo Hu, the head of the Beijing Meteorological Bureau, linked this week’s conditions to unusual atmospheric patterns caused by global warming.
Folks, it doesn’t matter what kind of weather we have — it’s all because of global warming. No evidence required, because the meme is firmly entrenched.

Global warming effect on the Sea by Sara Goudarzi
Warming oceans, one of the major consequences of global climate change, are making another marine species feel like a fish out of water, scientists report.
Biologists have known for years that global climate change, is linked to declining fish stocks, but a new study of eelpouts--big-headed fish that resemble eels--is the first to go deeper and see how warmer seas are linked to how fishes take in oxygen.
Scientists at the Alfred Wegener Institute for Polar and Marine Research in Germany studied the relationship between sea temperature and eelpouts counts in the Southern North Sea, combining data from the field with lab investigations of eelpout physiology.
The researchers not only found that the oxygen levels in the waters of the North and Baltic seas have dropped due to increasing temperatures over the past 50 years, a factor that reduces fish populations. They also found that eelpouts need more oxygen in warmer waters, a second factor that is reducing their numbers.
Difficulty in taking up oxygen via respiration and blood circulation, caused by the warming waters, proved to be the key factor in diminishing the size of the fish stock.
The study, published in the Jan. 5 issue of the journal Science, also noted that the population of eelpouts dropped as average summer temperatures increased. The impact was also observed in the short term such that eelpout numbers decreased the year immediately after a warm summer. (global climate change )
Animals tolerate a limited range of environmental conditions. Anything out of their tolerance window can cause damage. Fish in the North Sea have evolved to tolerate a wider range of temperatures than fish elsewhere due to the large seasonal fluctuations there. However, warming waters and their impact on oxygen supply can stress fish to the point that their thermal tolerance range is thrown off and they perish, the scientists said.
In the future, eelpouts could prove to be important bioindicators that would help experts assess what might happen to other marine species in the region, the scientists said.
Worldwide, warming waters can be expected to strain species that require lots of oxygen, forcing them to either relocate to cooler waters or face.

awareness of global warming
Global warming is the increase in the average temperature of Earth's near-surface air and oceans since the mid-20th century and its projected continuation. Most of the observed temperature increase since the middle of the 20th century has been caused by increasing concentrations of greenhouse gases, which result from human activity such as the burning of fossil fuel and deforestation and the other. Global dimming, a result of increasing concentrations of atmospheric aerosols that block sunlight from reaching the surface, has partially countered the effects of warming induced by greenhouse gases.
Global warming will also cause a variety of implications to the universe on earth 'll also will give effect to all occupants of the earth. Event of global warming is ignored by the people will affect humans. Global warming is not only involve the disaster, but such effects would affect the economics, political, humanitarian and others. So as resident this planet together, let us preserve the planet and govern well
Remember that our planet as we are alive
