Really hot today! "How often have you heard that statement came out of the people around you or from yourself? You are not wrong, these data indicate that there is indeed the planet continues to experience an alarming increase in temperature from year to year. Besides the hot weather around us, you must also recognize the increasing number of natural disasters and natural phenomena that tend increasingly uncontrollable lately. Starting from flood, tornado, bursts of gas, until the rainfall which is erratic from year to year. Realize that these are all signs of nature which shows that our beloved planet is undergoing a process of damage that leads to destruction! This is directly related to global issues more intense lately discussed by the world community that is Global Warming. What is global warming? Briefly, global warming is the increasing of the average temperature of the earth's surface. The question is why the Earth's surface temperature can be increased?
Research has been conducted by experts during the last few decades show that the heat of the planet Earth was directly related to greenhouse gases generated by human activities. Gas that keeps the earth's surface temperature to keep warm is known by the term "greenhouse gases". Called greenhouse gases because of the work system gases are similar to the workings of the greenhouse that serves to hold the hot sun for the temperature inside the greenhouse to keep warm. That way, the plants in it will be able to grow well because it has a pretty hot sun. Our planet is basically gases need to keep life in it. Without the presence of greenhouse gases, the Earth will become too cold to live in the absence of an isolating layer of the sun's heat. For comparison, the planet Mars which have a thin layer of atmosphere and do not have the greenhouse effect has an average temperature of 32 degrees Celsius.
The biggest contributors to global warming today is Carbon Dioxide (CO2), methane (CH4) produced agriculture and livestock which is mainly from the digestive systems of animals, Nitrogen Oxide (NO) of fertilizer, and gases used in refrigerators and air conditioning (CFC). The destruction of forests which should serve as storage of CO2 is also increasingly aggravate this situation because the trees that die will release the stored CO2 into the atmosphere within its network. Each greenhouse gas has a global warming effect that really different. Some gas produces more severe heating effect of CO2. As an example, a molecule of methane produces 23 times the warming effect of CO2 molecules. NO molecules even generate up to 300 times the warming effect of CO2 molecules. Other gases such as chlorofluorocarbons (CFCs) have a warming effect of CO2 up to a thousand times. But fortunately the use of CFCs has been banned in many countries because CFCs have long been blamed for the destruction of the ozone layer.
