the development of educational materials via the Internet be done about global warming, the study documents the following
one. The definition of global warming,
global warming (Global Warming) due to the increase of gas that envelops the Earth's atmosphere. Making the temperature rise inside the world. As a result, global seasonal changes. And rising gas mainly caused by the burning of fossil fuels
causes global warming pollution 2.
Global warming or climate change (Climate Change) is a big problem in the world today. Note the temperature The higher worlds A major cause of greenhouse gas emissions from greenhouse warming. Are critical to the world Because such gas Carbon dioxide or methane, will retain some heat in the world. Not to reflect back into the atmosphere Otherwise, the world will become a moon. The frosty night Daytime heat Because there is no atmosphere to filter energy from the sun. This behavior is similar to the principle of the greenhouse. Often called Greenhouse (Greenhouse Effect) increases. Greenhouse gas The atmosphere has the ability to retain heat more greenhouse gases (Greenhouse Gas), a gas that has the ability to absorb infrared waves. Or infrared radiation well. These gases are needed to maintain a constant temperature in the Earth's atmosphere. If the atmosphere is not greenhouse gases in the atmosphere. Like other planets Then in the Solar System The temperature in the daytime heat. And at night the cold. Because these gases absorb radiant heat wave in daytime and slowly heat is radiated out at night. The temperature in the atmosphere does not change abruptly. There are many qualified gas absorption heat. And was classified as a greenhouse gas. The gas is naturally occurring and is caused by human activity. The main greenhouse gas is water vapor, carbon dioxide, ozone, methane and nitrous oxide FC, but greenhouse gases controlled by the Kyoto Protocol are only six types of gases to be caused by human activity. (Anthropogenic greenhouse gas emission) only include carbon dioxide (CO2), methane (CH4), nitrous oxide (N20) gas, hydro fluoro carbon. (HFC) gases Perry fluoro carbon (PFC) and sulfur Hague's fluoride (SF6) is also a greenhouse gas caused by human activity, that is another matter NCAA. FC (CFC or Chlorofluorocarbon) which is used as a refrigerant and used to produce foam. But not defined in the Kyoto Protocol, due to the restricted substances in the Montreal Protocol ago.
