What is global warming? Global warming is the average temperature of Earth has increased since 1950 until now the temperature continuing increasing. Global warming can also refer to climate change that causes an increase in the average of temperature. However, global warming is caused by natural events and human that are believed to contribute to increasing in average temperatures.

Causes of Global Warming

Global warming is a serious issue and is not a single issue but a number of environmental issues. Global warming is a rise in the surface temperature of the earth that has changed various life forms on the earth. The issues that cause global warming are divided into two categories include “natural” and “human influences” of global warming.

Natural Causes of Global Warming

The climate has continuously changed for centuries. The global warming happens because the natural rotation of the sun that changes the intensity of sunlight and moving closer to the earth.

Another cause of global warming is greenhouse gasses. Greenhouse gasses are carbon monoxide and sulfur dioxide it traps the solar heats rays and prevents it from escaping from the surface of the earth. This has cause the temperature of the earth increase.

Volcanic eruptions are another issue that causes global warming. For instance, a single volcanic eruption will release the amount of carbon dioxide and ash to the atmosphere. Once carbon dioxide increase, the temperature of earth increase and greenhouse trap the solar radiations in the earth.

Finally, methane is another issue that causes global warming. Methane is also a greenhouse gas. Methane is more effective in trapping heat in the atmosphere that carbon dioxide by 20 times. Usually methane gas can release from many areas. For instance, it can be from cattle, landfill, natural gas, petroleum systems, coal mining, mobile explosion, or industrial waste process.

Human Influences on Global Warming

Human influence has been a very serious issue now because a human does not take care of the earth.  The earth has been changing for many years until now it is still changing because of modern lifestyle of a human. Human activities include industrial production, burning fossil fuel, mining, cattle rearing or deforestation.

The first issue is industrial revolution. Industrial have been using fossil fuels for power machines. Everything that we use is involved in fossil fuel. For example, when we buy a mobile phone, the process of making mobile phone have involved machines and machines uses fossil fuels, during the process, carbon dioxide is releasing to the atmosphere. Besides industrial, transportation such as cars is also releasing carbon dioxide from exhaust.

Another issue is mining. During the process of mining, the methane will trap below the earth. Besides, rearing cattle will also cause methane because cattle released the form of manure. However, cattle is important because it make the latter equally responsible for the occurrence of global warming

Next is the most common issue that is deforestation. Deforestation is a human influence because a human has been cutting down trees to produce papers, wood, build houses or more. If human continuing deforestation, carbon dioxide will concentrate in the atmosphere because trees can absorb carbon dioxide from the atmosphere. Besides, human also releases carbon dioxide when breathe. Therefore the amounts of millions of people breath have release carbon dioxide to the atmosphere. If human continues deforestation, human breathing that releases carbon dioxide will stay in the atmosphere.

The Effect of Global Warming

The greenhouse gasses will stay in the atmosphere for many years since hundreds of years ago. However, the effect that global warming will cause on earth is extremely serious. There are many effects that will happen in the future if global warming continues. That includes polar ice caps melting, economic consequences, warmer waters and more hurricanes, spread of diseases and earthquake

The first effect is polar ice caps melting. As the temperature increase, the ice at the North Pole will melt. Once the ice melts the first effect will be raised on sea levels because the melting glaciers become oceans. According to the National Snow and Ice Data Center, “if the ice melted today, the seas would rise about 230 feet”. It affects many low-lying areas such as the Netherlands. In future, the Netherlands will be cover by water once the North Pole is melted. However, it is not going to happen so fast but the sea level will continue rise.

Another effect is the species loss of habitat. Species that include polar bears and tropical frogs will be extinct due to climate change. Besides, various birds will migrate to other places because animals are not like humans. They cannot adapt the habitat that changes their living or temperature.

Next effect is more hurricanes will occur and economic consequences still affect as well. Hurricane causes damage to houses and government needs to spend billions of dollars in damage and people need places to stay or have been killed. Once a disaster happens many people have died and diseases happen. Diseases are more serious because it can spread to other people very fast and more people will get the disease and the disease may become more serious because of different weather.

Overall of this assignment, I have understood that our earth is “sick”. We humans need to “heal” the earth. Global Warming have causes many problems for human but we human who make global warming happens. Many people have died because of disease or disaster. It also affects the economics of the country. However, we need to reduce the global warming by using less gasoline, recycle and human should help to reduce global warming instead of making the earth temperature increased. Our generation should start taking care of the earth because in the next generation they will suffer if we do not do reduce global warming. Therefore, global warming is a serious issue now. As a business student, we are learning it because we need to understand the effect of climate change that will affect us when we have our business and we can start saving the earth.
