Global warming is one of the topics that are still warmly discussed in various print and electronic media. Al Gore said that "The warnings about global warming have been extremely clear for a long time. We are facing a global climate crisis. It is deepending. We are entering a period of consequences. "Because of the effects of global warming increase from year to year. So what is global warming? What causes global warming to occur? Then how do we handle it?
Global warming is where the temperature changes in the atmosphere and surface on earth. Temperature affects the climate and metabolism of organisms. A living thing has an optimal temperature so that if the temperature on earth is changed it will get a very big negative impact. It can even make an organism end up in death.
According to environmental ecologists, in the 21st century, the earth's temperature has increased the temperature by 4 degrees Celsius. This temperature rise is caused by emissions gases from a previous life. This temperature rise can make the polar glaciers begin to melt. It can threaten the life of organisms at the poles. In addition, the melting of the glaciers will make sea levels rise and make the surface of the land sink.
A number of compounds that are predicted to be the cause of temperature rise are the gases derived from combustion that it carbon compounds, CFCs are considered as compounds that cause the rise in temperature. The accumulation of carbon emissions in the atmosphere will form a layer that holds the geothermal out. With such a heat of the earth will bounce back to earth and will increase the temperature on earth this event is also called the greenhouse gas effect.
CFC (chlorofluorocarbon) is a compound commonly used in refrigeration and in aerosol products (spray). Moreover, these compounds are often used in everyday life. This CFC is designated as the compound responsible for the depletion of the ozone layer. As a result, as CFCs are accumulating in the atmosphere causing oxygen to meet with chlorine and cause the ozone layer to slow down more and more slowly. Global warming is a very long process, therefore, to overcome it also need a long time. We need to do things like reduce the use of CFC-related tools, promote reforestation, using environmentally friendly fuels.
In conclusion, global warming is becoming a very critical issue to be discussed by various parts of the world. This action is caused by humans and the impact is also felt by humans themselves. To overcome this global warming it is very difficult to eliminate the full impact but we can reduce the impact.
