Global Warming

Background

Since ancient times until the man with the present, people often experience growth in each time period dilewatinya. Present human civilization has experienced a lot of progress. During development, the human lead in reliance on farming and agriculture. Through the life orientation, people are always trying to keep and preserve their environment appropriately to safeguard the survival of mankind. Humans now have experienced a hang time of the industrial revolution in the field of industrial life. By using the life orientation, world agriculture even go down slowly. The values ​​of human life it changed, especially in human interaction with the environment. The changes that occurred this produces a positive or negative impact. One of the impacts of the industrial revolution happened and still continues at present in human life and civilization is no impact to the environment around the man himself.

Expansion efforts made by industry stakeholders such as the development of factories and manufacturing production with great capacity to override attention to the impact of the environment is slowly but surely led to negligence that ultimately will harm environment and human habitation have been found within the member kehidupannya.Para indication of the presence of the largest impact on the global environment and the world as a result of industrial work is done and has been growing rapidly at this time. This negative impact is the warming of the world and is often referred to as Global Warming. However, the Global Warming problem as the problem is still being debated within the truth by some who think Global Warming is the reason that the speed limit was created for industrial development.

While there is still debate about the truth of Global Warming situation between environmental experts, the Global Warming problem is not able diungkiri to be scrutinized and examined further for the sake of human survival.

Global Warming or Global Warming is the availability of the average temperature increase in the atmosphere, ocean, and terrestrial Earth.
Global average temperature at the Earth's surface has risen 0.74 ° C ± 0:18 (1:33 ± 0:32 ° F) for a hundred years. Intergovernmental Panel on Climate Change (IPCC) concludes, "most of the increase in global average temperatures since the mid-20th century is most likely caused by increasing concentrations of greenhouse gases due to human activity" via the greenhouse effect. Conclusion This policy was submitted by at least 30 scientific and academic bodies, including the national science academies of all G8 countries. However, there are still some scientists who do not agree with some conclusions of the IPCC presented.

Climate models project be referred to by the IPCC shows global surface temperature will rise 1.1 to 6.4 ° C (2.0 to 11.5 ° F) between 1990 and 2100.Perbedaan guesstimate is caused by the use of different scenarios-scenarios of emissions of greenhouse gases in the future, as well as models of different climate sensitivities. Although most of the research focused on the period up to 2100, warming and rising sea water interface is estimated to be continuous for more than a thousand years even if greenhouse gas emissions level was mainly stabil.Ini reflect heat capacity of the oceans.

Estimated increase in global temperature will cause other changes such as sea level rise, increased intensity of extreme weather phenomena and changes in the amount and pattern of precipitation. The consequences of global warming is terpengaruhnya other agricultural products, the loss of glaciers, and a variety of animal extinction.

Cause of Global Warming

Greenhouse
All available energy source on Earth comes from the Sun. Most of the energy is shaped short wave radiation, including visible light. When this energy the Earth's surface, it changes from light into heat which warms the Earth. Earth's surface, will absorb heat and reflect back some rest. Some of this heat tangible long wave infrared radiation to outer space. Yet some remain trapped in the atmosphere warm the earth due to overwrite the amount of greenhouse gases other water vapor, carbon dioxide, sulfur dioxide and methane which trap radiation wave. These gases absorb and reflect back radiation emitted wave and consequently warmer Earth will be stored on the surface of the Earth. This condition occurs continuously, resulting in an annual average temperature of the earth continues to rise.

Feedback
nasir cause of global warming is also influenced by a variety of feedback processes that result. For example is the evaporation of water. In the case of heating due to increasing greenhouse gases such as CO2, warming will initially cause more amount of water evaporating into the atmosphere. Since water vapor itself is a greenhouse gas, warming will continue and increase the amount of water vapor in the air until reaching an equilibrium concentration of water vapor. Greenhouse gases it produces larger when compared to the effect of CO2 itself. (Although this feedback improve the absolute water content in the air, the air relative humidity nearly constant or even slightly decreased as the air becomes warms up).

This feedback should impact only slowly as CO2 has a long life in the atmosphere. Another important feedback is the loss of the ability to reflect light (albedo) by es.Ketika global temperatures increase, ice near the poles are melting at a growing pace. Melelehnya equivalent to the ice, land or water beneath will open. Good land or water has the ability to reflect light a little more when compared with ice, and consequently will absorb more sun radiation. This will increase the heating and raises even more ice melts, becomes an ongoing cycle

Several Genesis Of Global Warming Impact

1. FIRE
Forest fires are common analysis = d due to his increased its surface temperature d area due to the effects of global warming. happen in time of drought


2. ES which oozed
Analysis of d = melting polar d due to increased temperatures can drastically until melted polar ice

3. SEA SURFACE a raised
Her analysis = high sea level rise is caused by water d have melted ice from the polar direction

Small Steps to Prevent Major Hazards (Global Warming)
Talking about preventive measures, many have commented that feel themselves not ready. Not ready to use hybrid cars, is not ready to not use the air conditioner, not yet ready to use the computer for long. Though it is only a few of the various measures to prevent global warming. There are still many other ways, namely by  Start with small things, Start from yourself and from now on.

There is a perception that I think is somewhat of a misnomer, efforts to prevent global warming is often associated with a return to the stone age. Do not use airplanes when traveling, do not use a computer, do not use motor vehicles and many other no-no. Indeed, it is important in preventing global warming, but I think we should not attempt to make us care about global warming is not productive at work. Live naturally. If it is deemed necessary with aircraft flying, yes use. If it is necessary to use a computer, so use it. Efforts of care we can show that the use of 'reasonable'. Hope turned off when not in use.

One Small Step is a Big Leap!!

Several months ago when the energy crisis, PLN urge to turn a 5 watt regular bulbs turned on at night between the hours of 19:00 to 22:00 pm, because at these hours is going electricity peak load. Small sound right? Only a 5 watt bulbs. But when her whole would care to turn off the lights turned 5 watt usual, then the energy crisis can be resolved. One small step is a big leap, one small step done early is a big leap in the future. Do not hesitate to do little things for good in the future. That's the hope to inspire each person to be able to take part in the efforts concerned Global Warming.
