Global warming and green house gases

Air contains 380 now on part per million of carbon dioxide which is the main gas causing global warming compared with 275 the parts per million of air before the industrial revolution



What global warming?

Global warming: a progressive rise in temperature of the bottom layer near the surface of the Earth atmosphere because this height and increase the emission.green house gases Gases greenhouse gases or deep green ", the most important greenhouse gas, methane, which consists of mikrobet interactions in rice fields and ruminant livestock and burning of biomass (trees, plants and animal waste) and brackish Marsh water produces. In addition to methane gas now rose oxide (consisting also of mikrobet interactions occur in water and soil) and chlorofluorocarbons (which cause erosion of the ozone layer) and finally ozone gas, which consists inlower atmosphere.

Greenhouse scholars concept

Greenhouse: the temperature is rising in a change in the flow of thermal energy and environment. And this name is usually called the rising rate of Earth temperatures. And on the causes of this phenomenon on the ground level is due to the phenomenon of global warming planet divided only scientists who argue that natural phenomenon and that the Earth's climate is a natural hot and cold periods been citing this by the somewhat icy or cold between the 17th and 18th century in Europe, and another attribute the phenomenon to accumulation Greenhouse gases in the atmosphere.

At the end of the nineteenth and twentieth century disturbance emerged in atmospheric constituents resulting from human activities such as industry, transport, and since the industrial revolution and so far as a result of fossil fuel dependency "coal, oil, natural gas as a source of energy, and using alkloroflorokarbon gases in significant industries, led by scientists at the increased warmth on the Earth's surface and a So-called " greenhouseGlobal Warning " this is the result of increase:

Greenhouse gases

The following chemical compounds are the most important greenhouse gases:

1-Water vapour

2. Carbon dioxideCO2

3- (Now rose oxideN2O)

4-Methane CH4

5-Ozone O3

6-Alklorflorkrbon FCs))

The role of greenhouse gases

Heat up Earth from the Sun leads to high fever and was steaming water and air both horizontally and vertically; meanwhile lost ground thermal energy from terrestrial radiation emitted in the form of rays, "infrared", where the rate of solar energy is gaining ground equivalent to inspecting the ground to space radiation. This thermal equilibrium leads to proven surface temperature rate when a certain amount is 15 °s.

Greenhouse gases "play vital and important in moderating the temperature of the Earth's surface where the Earth sucks:-energy from solar radiation and reflect part of the radiation into outer space, and part of this energy or radiation absorbed by certain gases in the atmosphere. These gases are greenhouse gases play a vital role, as in the heating surface to the level that makes life possible on Earth.

-Where the natural gas to absorb part of the infrared light emitted from the surface and keep the atmosphere to keep surface temperatures constant natural webmadlha "no limits 15 °x". Without these gases to the surface temperature got to 18 °° c.

The foregoing and as a result of growing humanitarian activities and particularly industrialized we notice now: the increase of greenhouse gases to the point of exceeding what atmosphere to maintain surface temperatures constant and when a certain amount. The presence of additional quantities of greenhouse gases and their accumulation in the atmosphere to retain more heat in the atmosphere and surface temperature begins to rise.

Indicators for the beginning of this phenomenon :

Air contains 38 is currently part of million CO2 which is the main gas causing global warming compared to 275 parts per million of air before the industrial revolution. Here we note that the amount of CO2 concentration in the atmosphere is about 30% higher than pre-industrial concentration.



Global warming is already changing the world "

To declare a United Nations report that climate change already affects huge leaves on the nature of the world and its environment.

The report believes climate change forum for coordination between Governments, that there is a noticeable effect on human societies and the impact on human beings less pronounced impact on nature.

Draft report warns seen by BBC Difficulties facing human communities adapt to all potential climate changes.

The report will include the high temperatures of the planet 1.5 one degree Celsius for general 1990 levels will make about one third of the animal and plant species in danger of extinction.

He adds that more than 1 billion people will be more vulnerable to water shortages, mainly to thaw icy mountain and spaces that serve as a natural reservoir of fresh water.

Expected conflicts of various parties on drafting the report before its publication in the language that will be conclusive and did not affect the general direction.

Meet scientists and Government officials in Brussels intensive negotiations before the report.

And interviewed officials of the United States, China and India scientists about the drafting of the report which had devastating effects "warns" millions "especially in the poorer world.

Because many scientists global warming to the so-called greenhouse gases, like carbon dioxide, heavy state industries by burning fossil fuels in the atmosphere of the planet.

The report includes 29 more than 1,000 scientific data on forms of change in physical and biological aspects of the natural world.

Report says 85% of those data points to global warming.

Studies on global warming.

According to a study published in science magazine famous science SCIENCE , The warming of the Earth and increase the risk of epidemics among wildlife and marine with increased risks of transmission of these diseases to humans.

Tell the world ((Woodrow harviell)) of the University (Cornell) and Chair of scientific research ((that is surprising and astonishment that climate-sensitive diseases appear across different types of generators of viruses and disease bacteria, parasites and infect a wide variety of organisms, including corals and shellfish and wild plants and humans sounds)).

Researchers have devoted their studies for two years about the relationship between the change in temperature and the growth of viruses, bacteria and other disease factors with some factors, such as rodents, mosquitoes, flies, and have found that with rising temperature, increases the activity of vector insects-wekward-infect more humans and animals, and found that successive winters and temperate Thermally lost its natural role in reducing a bacterial, viruses, vectors, as well as Summers has noted that in the last decade of the last century and increased heat, increasing the length of time that disease can be passed through to the living species vulnerable to thermal changes, especially in seas and oceans.

Says researcher ((Richard austvild)) of the Institute for the study of ecosystems in New York (( is not only the problem of white and colour Morgan says environmentalists, or some sporadic cases of malaria can be controlled, it has many different facets and we are concerned )).

We study the lives of many birds and animals affected by high temperatures, and little bird researchers for example (alakiba) in Hawaii, where live birds 700 altitude meters in the mountains of the island (Maui) , invoking cold on this height of mosquitoes and insects that destroy her life, but the heat make mosquitoes up to such Height of the bottomless pit with malaria afflicting spores preparation of these birds weftkt by leaving only a small number
