People usually pay attention to the weather changes within a week, a month, or even compare the changes to the previous few years. As much as that is the case, there are some changes that cannot easily be seen and can only be observed by the scientists using some sensitive equipment. These changes make up certain patterns in the weather and have a tendency to occur every year. These overall weather changes are referred to as climate. Scientists have been claiming that there are some major changes to the climate everywhere in the world. These changes already have dire consequences to the human live. On such climate change is global warming (Cline, 1992).
Global warming (global climate change) is a global topic that has drawn a huge interest from the scientific researchers. Global warming has major impacts on other several sciences such as biology, geology, and environmental sciences among others. Therefore, this subject of global warming has provided opportunities for a wide area of the research studies. The effects of global warming are real and can easily be measured. The causes are mainly from the human being and the effects on the human being are also severe. The main cause of global warming is deforestation and the industrial emissions thus increasing greenhouse gases in the earth’s atmosphere (Vitousek, 1994).
The gases block the heat and thus prevent it from escaping the earth’s surface. These gases such as nitrous oxide, carbon dioxide, methane, and water vapor remain semi-permanently in the earth’s atmosphere and fail to respond either physically or chemically to the temperature changes thus causing changes in the climate. The greenhouse eventually absorbs the atmospheric heat thus causing global warming. Global warming is an increase in the temperature of the earth’s surface. If the global warming continues there would be some dangers living in the earth. The main effects and impacts of the global warming are (Hansen, 1998):
- Climate change – Global warming has caused the change in climate where the warmth of the world has increased rapidly. Additionally, researchers have predicted regional climate changes along the ecosystem.
- Changes in the sea level – The sea level has changed rapidly due to the global warming. The changes in the sea levels have been caused by the greenhouse effects. There are four major changes which happen before the changes in the sea level which are melting of the mountain glacier, thermal expansion, melting of the Greenland ice sheet, and melting of the polar ice. The changes in the sea levels may submerge the coastal cities and ports. Additionally, many islands may also vanish from the earth’s surface (Chapin & Körner, 2013)
- Human health – The human health is also at risk because of the global warming in form of spread of diseases. As the warmth on the earth’s surface increases, people might become affected by the tropical diseases.
- Water balance – There might be problems in the availability of water which may also become expensive and harder to solve. Global warming may make warmer parts of the world to have water crisis while in some parts it will be wetter than currently (Wheeler & Von Braun, 2013).
Global warming is a serious issue whose effects can lead to serious consequences at the world level. Although global warming is a worldwide problem at the moment, it can be easily controlled if people can agree to minimize the emission of the greenhouse gasses into the environment in which they live. Additionally, there are chances that global warming can be stopped if people can be taught its effects on ways in which they can prevent it.
