300 word essay on climate change
Answers
Answer:
As the name suggests, climate change is a change in the climatic conditions on the Earth. Several factors contribute towards this change since centuries. However, the more recent ones that are mainly a result of human activities are having a negative repercussion on the atmosphere.
Researchers continually observe the pattern to understand the past, present as well as the future climatic conditions. A record of the climate has been accumulated and is updated regularly based on the geological evidences to study the changes occurred. These evidences include the records of flora and fauna, glacial and periglacial processes, records of sea levels, borehole temperature profiles and sediment layers among other things.
Here is a closer look at the causes and effects of climate change:
Causes of Climate Change
The factors that contribute towards climate change are:
Solar Radiation
The energy emitted by the Sun that reaches the Earth and is carried further to different parts of the planet by winds and ocean currents is one of the main reasons for climatic change.
Human Activities
The new age technology is adding to the emission of carbon on the planet which in turn is having a negative impact on the climate.
Apart from this, the orbital variations, plate tectonics and volcanic eruptions also cause changes in the climate.
Effects of Climate Change
Impact on Forests and Wildlife
A number of species of plants and animals have gone extinct due to the change in the climatic conditions and many others are on the verge of going extinct. With the mass extinction of trees in certain regions, many forests are also diminishing.
Impact on Water
Changes in the climatic conditions are also having a negative impact on the water system. It has resulted in the melting of glaciers and erratic rainfall patterns that in turn are leading to environmental imbalance.
It is important to take the climate change issue seriously and control human activities that are contributing towards this change.

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.
