Describe 3 ways that global warming will affect our nation’s national security in the future. What are some short term solutions?
Global warming is the effect of the rise in climatic temperatures around the world’s climatic system. This effect has been witnessed over the recent years with a change in weather and climatic patterns (Butera 2018). It is caused by an increase in greenhouse gases in the atmosphere that trap most of sun’s radiation. In this way, little sun’s radiation goes back into space making the earth to be warmer over time. Most of recent devastating climatic changes have been attributed to global warming.
The rise in temperatures is likely to result in prolonged heat waves. Our bodies will suffer some health complications while trying to adapt to the changes in the environment. In severe cases, it can result to deaths (Saad & Jones, 2016). The workforce will be reduced since most of the people will be seeking health services or they may be too weak to work. The hospitals will also be overwhelmed by the number of patients visiting the health facilities. Therefore, this can cause a threat to nation’s economic security.
Climate change caused by global warming can also be a threat to the nation’s military. The rise in water levels dues to melting of polar ice will result to flooding of military bases. In this way, their operations might come to a halt since some of the equipment might get destroyed by the flooding. An example is when the 1992 Hurricane Andrew nearly wiped out Homestead Air Force Base in Florida (Saad & Jones, 2016). Such events may jeopardize the military operations in their work of providing security to the people.
Agriculture and fisheries are dependent on favorable climatic conditions. Increase in the greenhouse gases increases the temperature that will result in an increase in water evaporation. Crops will find it hard to survive even under irrigation. The crops might wither before maturity leading to low harvest. The soil acidity will also increase making it unpleasant for crops growth. An increase in water temperatures will also shift the aquatic ecosystem especially breeding of the fish (Saad & Jones, 2016). Some species will become extinct while some will move further into the deeper sea. Such occurrences will be a threat to our nation’s food security.
The urban areas should adopt green infrastructure to help in absorption of excess run-off water during rain or hurricanes. This prevents unnecessary flooding and also creates a cooler climate that might counter the effects of heat wave. The people should also be taught on how to reduce carbon (IV) oxide emissions into the atmosphere but instead plant trees (Saad & Jones, 2016). This will help in creating better conditions for practicing agriculture and increase on the output.
What is the most common-sense solution for cutting carbon emissions? Why? What are the strengths and weaknesses of your choice?
Most of the fuels in use in the industries and even in our homes are fossil fuels. These fuels contain a significant amount of carbon that goes into the atmosphere when they burn up. This eventually contributes to the rise in global temperatures due to global warming. However, there are some forms of energy that produce zero emission of carbon into the atmosphere. These sources of energy are known as green energy or renewable source of energy since they can be reused without depletion (Owusu & Asumadu, 2016).
Wind power produces clean source of energy. Wind turbines can be installed in areas that are prone to windy conditions. The turbines are used to drive generators that produce electricity in a similar way that diesel-driven generators work. There are no emissions with this kind of energy since wind is used instead of fossil fuels (Butera 2018). The use of solar panels to harness sunlight to provide electricity is also a clean energy source. Geothermal power is another source of renewable energy. The pressure from the geothermal wells is used to drive generators that produce electricity.
The renewable sources of energy are considered to be an alternative to the fossil fuels such as oil and coal. They are readily available and they do not produce carbon unlike the fossil fuels that emit carbon (IV) oxide into the atmosphere when they burn. The wind and sun are inexhaustible and they safeguard the environment against pollution.
The strengths of using renewable energy is that it safe and clean when compared to the fossil fuels. This means that they do not emit carbon that will contribute in global warming (Owusu & Asumadu, 2016). Another advantage is that multiple forms of renewable energy exist such as sunlight and wind power. One can choose which one to use depending on their convenience.
However, there are some weaknesses in using the renewable energy. One is that they are usually location specific. Although many areas experience windy conditions, wind turbines need to be installed to areas that experience a certain wind intensity that is not available in all areas. Usually the turbines are installed in hilly areas or great plains (Owusu & Asumadu, 2016). The renewable energy sources also require a huge capital in investment and setting up reliable plant to harness the power. This makes it to be available in limited area where people are able to meet the costs of operation.
