Essay on Climate Change in 400 words....!!!
Climate change is basically a modification in the distribution of the pattern of the average weather conditions on the Earth. When this change lasts for a few decades or centuries, it is referred to as climatic change. Several factors contribute towards change in the climatic conditions. Here is a look at these contributory factors and repercussions of climate change:
Factors Responsible for Climate Change
Here is a look at some of the main factors that cause a change in the climatic conditions on the Earth:
Solar Radiation
Sun radiates its energy that reaches the Earth and is emitted back in the space. This energy is carried to different parts of the globe by way of winds, ocean currents and other mechanisms, thereby, impacting their climatic conditions.
Volcanic Eruption
Volcano eruption is quite common on the Earth and this is another reason for the climatic change here. The effect of volcanic eruption on the Earth lasts for a few years.
Human Activities
Life on the Earth itself contributes to the changes in its climate. The process of carbon emission by humans is one of the reasons that lead to changes in the climate. Emission of carbon due to fossil fuel combustion, burning of industrial wastes and vehicular pollution add to it.
Orbital Variations
Variation in the Earth’s orbit causes a change in the seasonal distribution of sunlight received on it. This variation results in Milankovitch cycles that impact the climate adversely.
Climate Change Effects
Here is a look at the repercussions of climate change:
Effect on Forests
Forests serve as home for numerous species of animals and plants and maintain the ecological balance on the Earth. However, changes in the climate have led to extinction of forests in many regions.
Effect on Water
The water system on the Earth has been disturbed due to climate change. The rainfall pattern has become erratic thereby causing extreme conditions such as drought and flood. It has also caused melting of glaciers.
Effect on Wildlife
Climatic changes have become a threat for the survival of various wild species. A number of species of wild animals and plants have gone down and many are on the verge of extinction.
Conclusion
Climate change is a global problem. Besides the natural forces, human activities have also contributed majorly to this change. While the natural forces cannot be controlled, human beings must ensure they control the activities that lead to negative impact on the weather in order to maintain harmony on the Earth.
Answer:
Nowadays, people around the world has been focusing on facing climate change. Climate change is the major global challenge today, and the world is becoming more vulnerable to this change. The recent report from United Nations predicted that average global temperature could increase by 6˚ Celsius at the end of the century (Vidal 2013). Increasing temperature causes warming oceans and lead to changing on weather and rainfall pattern which threats both urban and rural population. Australian Academy of Science defines climate change as the long term change in weather pattern which causes several events such as melting of polar ice, raising sea level, and increasing intensity of natural disaster (Australian Academy of Science 2018). This essay outlines the main problems caused by climate change, and evaluate three possible strategies to address its negative impacts. The essay argues that climate change has negative impacts on human life. However, its impact could significantly be reduced by implementing three strategies, including supporting green transportation, building green city and implementing organic farming. There are various potential impacts of climate change on human life. Firstly, the rise of sea level as a result of increasing global temperature and melting of polar ice. A report from Union of Concerned Scientist points out that average global sea level has increased by 8 inches since last century (Union of Concerned Scientists 2018). This increases the risk for low laying areas from flood and threats coastal properties. Nowadays, 65% of major cities are located in low-laying coastal zones (Nordhaus 2006, cited in Hunt & Watkiss 2010). Secondly, climate change may also affect on energy demand. European Environmental Agency claims that there has been increasing trend in cooling demand during summer season and predicts 30% increase in the use of energy by 2080 due to air conditioning (Hunt & Watkiss 2010). Another impact of climate change is the effect on human health. The report from Intergovernmental Panel on Climate Change (IPCC) points out that climate change affects human health due todecreasing quality of fresh air caused by air pollution and disruption of food supplies (WHO 2007). These three impacts are the major impacts of climate change, and it would be worsened by the rapid growth of urbanisation and population. Without systematic and organised action, such effects from climate changes will be become more difficult in the future. In order to address the effects of climate change, there are three strategies that can be done. First of all by establishing green transportation. Transportation is the most important sources of emission. To sum up, climate change has negative impacts on human life. There are many problems that is caused by climate change, including increasing sea level, rising demand on energy, and threatening human health. This essay argues that three solutions including: supporting green transportation, building greener city and implementing organic farming could significantly address these problems.
