The cause of global warming is what

100 years ago when greenhouse gases in Earth's atmosphere is not much concentration. Heat waves are reflected off the world have very different human activities cause greenhouse gases. Earth's atmosphere in concentrations up Heat wave has accumulated on the surface.
Global warming is not just talking about that happened or recently But climate change began when about 100 years ago, after the man started about steam engine and bring fossil fuels including coal and oil to use and that is the beginning of the release of carbon dioxide to the atmosphere. in large quantities by human hands.
Scientists predicted that approximately a century ago are a reality today.
About Year 1890 Svante Arrhenius, a Swedish scientist. Has studied the relationship between carbon dioxide in the atmosphere with the average temperature of the earth's surface and found that if carbon dioxide in the atmosphere of the world halve The average temperature of the earth's surface down to 5 degrees Celsius
During that time, the early industrial era. Emissions are different. Svante more up-to-air prediction that in future the world will heat up From burning coal as fuel. Causing enormous quantities of carbon dioxide rising into Earth's atmosphere. The phenomenon is called that. Global warming.
Global warming. Is similar to that we build an outdoor greenhouse. Sunlight to pass into the greenhouse. But heat can not occur outside the vent. High temperatures inside greenhouses and more.
Normally Earth's atmosphere consists of various gases and water vapor when short wave radiation from the sun through the atmosphere into surface. It will be absorbed by the ground water plants and animals will then be spit out of energy in the form of long wave infrared radiation. A heat wave. Back to the atmosphere and some is stored the gas in the atmosphere that wrapped the world. So the world of the past, we can maintain the proper temperature. Not hot like Venus. Or cold like Mars.



Carl Sagan (Carl Sagan), scientists of the world's greatest one ever said that "If you remove the polishing liquid paint globe Thickness of liquid is compared with the atmosphere compared to the size of the world. "



Today, Earth's atmosphere with greenhouse gases are covered too. Greenhouse gases include carbon dioxide as the main Including methane gas, CS gas, ozone, etc. FC has good properties of absorption and retention infrared radiation. Infrared radiation, so it should reflect the world outside. Retention will be accumulated in the atmosphere. Surface resulting in global warming and more.



Dr. Arnon Snidvongs Director of network analysis, research and training to change the world in Southeast Asia. Chulalongkorn University, told us that
"Problem of global warming is. Greenhouse gases, it is not thicker. But it strengthened. The main reason is the carbon that had accumulated in the form of oil and coal. It should be in its place on earth. But we came out to burn the energy used. The result is that carbon dioxide The natural, if we give enough time for it. Natural processes in the world will gradually Carbon dioxide in the atmosphere to pull away. Now, we dig up carbon burning 80 million barrels per day, it quickly than natural processes can be removed. It has accumulated in the atmosphere increased as the current global warming is too serious a natural condition. "

2. In addition to gas and carbon dioxide. Greenhouse gases also include what.

Greenhouse gases include gases is important.

53% carbon dioxide (380 ppm).

In today's atmosphere of carbon dioxide molecules in every 380 million molecules of air mass or a 380 ppm (parts per million) and has increased about 1 percent per year compared to approximately 100 years ago during the Industrial Revolution. Saturation level of carbon dioxide in the atmosphere at about 280 ppm, scientists predict that in another 100 years if no changes or slow down the power consumption of fossil fuels. Concentration of carbon dioxide will increase to almost 1,000 ppm, which increases at a rate faster than the past much

Why carbon dioxide rose and more. In the atmosphere. In addition to that from burning fossil fuels already. Another significant cause is. The deforestation and burning forests into farmland. Because the tree is a good feature to prevent absorption of carbon dioxide to the atmosphere rise. When the forest is reduced. Carbon dioxide in the atmosphere has increased. And burned forest also remains in the soil become damaged as this type of gas in the atmosphere increased by

B 10 years before scientists can survey measuring carbon dioxide and global temperature back to 650,000 years ago, when analyzed from the ice bar is deep down under the earth's surface. And have concluded that global temperature is related to the amount of carbon dioxide in the atmosphere. Any time when a lot of carbon dioxide. Global temperature will rise by



But it is alarming period 650,000 years ago without any of the increased amount of carbon dioxide in excess of 300 ppm as in the present



Actually, just do not think that carbon dioxide is always the culprit. If the world is lacking because this type of gas. Plants would not be able to photosynthesize and create food for the mankind. But only the man made carbon dioxide comes with too much And beyond the natural removal process.

17% methane (1.8 ppm).

Of gases from rice cultivation. Husbandry And the burning of fossil fuels. Although methane in the atmosphere will be negligible. But methane gas molecules can absorb infrared rays than carbon dioxide to 25 times.



Problem of emission of methane in the atmosphere has become a political issue between countries. That is the last time the International Conference on the global warming problem. Developed countries, mostly in industries that release carbon dioxide in large quantities. Will try to raise the issue that developing countries, mostly in agriculture. Methane emission is too much. The examples of rice for the flooding to control weeds. The lack of oxygen to the soil. Some bacteria can produce more methane. Because methane is a storage heat better. Therefore, developed countries and then trying to pressure developing countries to share responsibility with a certain level.



13% earth's surface level ozone (0.03 ppm).

When the high atmosphere. Ozone protects Earth from ultraviolet radiation. However, ozone levels in the earth's surface acts as the SIM Dan substances out that react with tissues of living organisms. Can be considered as ozone in the atmosphere that even the world a little. However, the ability to absorb infrared radiation. Warm up with the world.



12% nitrous oxide gas (0.3 ppm).

Nylon industrial fiber production. Chemical and plastics industries. Nitric acid used in the production process. The emission of nitrous oxide to the atmosphere. Including nitrogen fertilizer used in farming. Even if the natural gas will be released this type of out. However, nitrous oxide from the gas industry is increasing rapidly. Resulting in heating up the atmosphere.

5% gas, C FC (1 ppm).

This type of gas is a gas containing compounds chloro Fluid Organic Carbon Road. Are used in air conditioning, refrigerator, spray liquid fire, are a major cause of vulnerability of the ozone hole in the atmosphere. The ultraviolet light down to earth even more. Although the current global campaign to reduce emissions, CFO C by up to 40% but still remain in the atmosphere has to absorb infrared radiation. And heat accumulation, approximately 0.28 watts / square meter

3. Who are the carbon dioxide emissions.
"There is new evidence that confirm global warming in the last 50 years mostly from human activities."
IPCC (Intergovernmental Panel on Climate Change).
Year 2007 IPCC or the International Commission on climate change. Including more than 2,500 scientists from around the world come together to work investigates the facts and solve global warming have reported the possibility that more than 90 percent of human action. Such as burning fossil fuels. Are a major cause of global warming in the last 50 years.

Current atmospheric carbon dioxide is the world's three billion tons of carbon dioxide humans emit into the atmosphere each year to 26,000 million tons, while the 1970 emissions of this type of man is 15,000 million tons annually by human activities. emission of carbon dioxide to the atmosphere include

Industrial growth is a major catalyst for the fuel and electricity. Currently China and India, the rate of economic growth rapidly Allegedly contributed to global warming. No different from the United States and European countries.

Including the use of electrical appliances. Air conditioning And facilities in the daily life of people in the city. This is all according to the emission of carbon dioxide total

Transport by air and sea around 22%.

Today, people travel through increased vehicle. Demand for car use is rapidly increasing. Resulting in carbon dioxide emissions per year 2% higher and potentially more and more expected next 15 years the world will have a total of 700 million automotive vehicles.

And since the low cost airlines. People around the world are traveling by plane hits the rise. Not to count that airlines around the world are there plans to expand air routes to link up across all countries in the future. The energy metabolism of the aircraft will cause more gas pollution in the sky. And also to destroy ozone in the atmosphere has decreased.



Agriculture approximately 4%.

Forest Research Institute of the Brazilian Amazon reported. The result of the Amazon forest burned dozens of million hectares each year to turn into farmland. The emission of carbon dioxide to the atmosphere more than four times the amount of gas caused by this type of Brazilian oil burned for energy.



4. In which most carbon dioxide emissions.

In the emission of carbon dioxide to the atmosphere most of the countries with the U.S. resources to the most extravagant. American emissions of this type of 5,762 million tons per year, representing 24 percent of global emissions. While the U.S. has a population of only 5 percent of the population in the world. Followed by China at the rate of economic growth the world's highest consecutive years. China, resulting in carbon dioxide emissions to the atmosphere each year 3,474 million tons or 15 percent.

While the Thai people, particularly Bangkok Carbon dioxide emissions to the atmosphere each year 172 million tons or 2.8 tons per year each, which is higher than countries in Southeast Asia.



If represent carbon dioxide emissions per capita will find that Arab population in the United Arab Emirates, Kuwait are all top-post. Emissions by this kind of 26 tons each year because these countries have less population. But oil is a major industrial activities that cause emissions of carbon dioxide in high volume. Followed by people in capitalist countries, including Australia, United States, Canada, full of carbon dioxide emissions each 15-20 tons per year.

5. Today, global warming or how

Today, the average temperature of Earth increased by about one degree Celsius compared to the approximately 100 years ago, especially after the 1980 global temperature has increased rapidly

First glance may seem to understand that global warming a little. Do not forget that there is a year round average temperature of the whole world around 100 years ago, in fact, land is often warming than surface water. That is, while the land area which is only about 20 percent of the earth warming 3-4 degrees Celsius over the sea surface, which is four times the earth may be warming slightly.
