What is climate change? To understand climate change, we must first know what climate is and how it is different from the weather. Weather is what we see change on a day to day basis. We can see and feel the changes in weather: sunny one day, rainy the next, and back to sunny again. Weather also is the change in temperatures: sometimes it is hot, and sometimes it is cold, depending on the time of year or the place that you are in. Climate, on the other hand, is the usual temperature of a place. For example, a regional climate may be wet and cold in the winter, but warm and dry in the summer. There have been anomalies–extremes where it has snowed year round. Not all climates are the same. The global temperature has been rising each year; however, climate change is much more than just that. In addition to the climates of individual places, there is also Earth’s climate, which is the result of combining all of the climates around the world together. Climate change is often referred to as global warming. Climate change is defined as changes in the usual weather found in a place. This could be a wide range of changes like how much rain a city gets in a year, snowing in places it does not usually snow, or most commonly, changes in a place’s usual temperature. Earth’s climate is also subject to climate change. The planet can experience rising temperatures, or it is possible for rain and snow patterns to shift, causing it to do so in places it would not usually.
Simply put, weather changes in a matter of hours or less, whereas climate takes hundreds of years to change.
In the past 100 years, Earth’s temperature has increased about one degree Fahrenheit. This may not seem detrimental on the surface, but minute changes in Earth’s climate has had massive effects. While Earth’s temperature rises independently, humanity plays a contributing role in speeding up the process of rising temperatures that influence the stasis of the Earth’s atmosphere, at an alarming rate. The Earth’s atmosphere consists layers, made of nitrogen , oxygen, argon, neon, helium, carbon dioxide, and methane. Key components in climate change like greenhouse gases contribute to the dismantling of the atmosphere, a term coined “the greenhouse effect” because of the absorption and transmittance of infrared radiation. Greenhouse gases impact the ozone layer. When it comes to climate change, the ozone layer is a layer in the Earth’s stratosphere that contains high amounts of ozone. Ozone absorbs most of the ultraviolet radiation emitted from the sun, and prevents it from reaching Earth. Since the Industrial Revolution, there has been a 40% increase in carbon dioxide in the Earth’s atmosphere. The largest contributing factor of the emissions of greenhouse gases is the burning of fossil fuels by factories and industries, such as coal, oil, and natural gas. Doing so pollutes the air, and releases these harmful gases into the atmosphere, counteracting the Earth’s natural greenhouse process. As it stands, the Earth’s surface temperature could reach record-breaking temperatures by 2047, which would cause ecosystems to fall apart and the livelihoods of people worldwide would be effected. If humanity continues to emit the amount of greenhouse gases into the air as we currently are, there could be dangerous consequences.

Based on Figure 1 (above), it is easy to see that the causes of climate change are far outweighed by the consequences. There are very few man-made causes, but they each have many effects on Earth’s climate.
The Clean Air Act is known as the most successful act in place to protect the environment. Passed in 1970 with the purpose of reducing the air pollution in the country by limiting the amount of pollution put into the air by industries, like chemical plants and steel mills. Under the Obama Administration, the Clean Air Act was used to help reduce the output of carbon dioxide and other greenhouse gases into the air. The National Environmental Policy Act requires federal agencies to take into consideration the environment when making important decisions, such as building a highway or deforestation. It requires agencies to prepare an Environment Impact Statement to report how the actions may affect the environment. This act also assembled the Council on Environmental Quality to advise the President on environmental issues. While these laws have been effective in reducing the damages on the Earth’s ozone layer put out by the United States, the integrity of the ozone layer is still at stake. Recent studies have found that the ozone layer shows signs of healing.
The Universal Declaration of Human Rights (UDHR) and its relation to Climate Change
Under Article 22 of the UDHR, everyone has the right to security and economic welfare. The effects of climate change infringe upon this right because it jeopardizes environmental integrity. Climate change effects us all, and is supported by scientific evidence around the globe. It transcends political parties, race, and social class.
Everyone on Earth shares the same climate.
In the wave of executive orders issued out by President Trump, he re-initiated the construction of the Dakota Access Pipeline (DAPL), a controversial project that was halted by the Obama Administration. The DAPL was originally routed through Bismarck, North Dakota, but after the mostly-white residents refused to allow construction on the grounds of “polluting their water supply”, it was rerouted through Standing Rock. The pipeline’s construction threatens to destroy the Standing Rock Sioux Tribe’s historic, religious, and cultural sites. It also contributes to climate change and may cause untold damage to the environment, such as water pollution–presently acknowledged by the Bismarck community–and explosions. The DAPL effects the health and security of the Sioux Tribe.
Another prime example of climate change infringing upon the health of people is the smog currently plaguing China, which is a result of burning massive amounts of coal. The emissions coming from China’s most industrialized areas were five times the national average in 2016 compared to 2015. Citizens of China are having to wear face masks to combat “serious aggravation of heart or lung disease and premature mortality in persons with cardiopulmonary disease and the elderly; serious risk of respiratory effects in general population.” While measures have been taken to reduce the pollution, such as wind-mill farms, the smog still continues to get worse because of the amount of coal being burned. Schools have been shut down, flights are being cancelled, and people are afraid to leave their homes because of the smog.
There have been many observable effects of climate change on the environment. Endangered species, both animal and plant, across the globe are dwindling in numbers due to the fluctuating temperatures in their habitats. Lakes and rivers are drying up or reaching low levels. The glaciers are melting, ocean levels and temperatures are rising. Here in Alabama, we suffered a drought this past summer and an oil leak this fall. The effects that scientists had predicted would happen due to climate change have started to occur.
Climate Change Effecting the Refugee Crisis
According to the Global Military Advisory Council on Climate Change (GMACCC), climate change has been noted as the “greatest security threat of the 21st Century”. The council has also said that climate change will cause a refugee crisis of “unimaginable scale”, as the effects of climate change have already pushed many refugees into Europe. There are claims that a lack of natural resources due to climate change may have been a contributing factor in the Syrian War, namely oil. Despite the abundance of oil in the Middle East, the over-excavation of oil brought about a ecosystem collapse, resulting in the dispersion of greenhouse gases into the atmosphere. The land began losing its integrity which affected the economic output as Syrians were unable to produce goods due to the ill-suited climate.
If the Earth’s temperature continues to rise causing the glaciers to melt, causing a rise in sea levels, 20% of Bangladesh will flood, creating additional climate refugees. The potential is over 30 million people forced to evacuate and relocate their lives and families as a result of climate change. In light of this potential threat, Bangladesh is asking wealthier countries to be ready to accept millions of displaced families.
“Climate change could lead to a humanitarian crisis of epic proportions. We’re already seeing migration of large numbers of people around the world because of food scarcity, water insecurity and extreme weather, and this is set to become the new normal.” – Brig Gen Stephen Cheney, member of the US Department of State’s foreign affairs policy board and CEO of the American Security Project
The United States’ impact on the Earth’s climate is profound. As an industrial country, we have a notable carbon footprint. In other words, what we do largely impacts those around the globe as it effects Earth’s climate, just as what China does impacts us and others even if they are across the globe. It is important to be aware of the growing concerns stemming from climate change, whether it is down the street or thousands of miles away. As I mentioned, we all share the Earth’s climate, so we are all effected by the changes in some form or another. Lives and families are being torn apart across the world due to changes in the climate. We as humans are responsible for destroying families’ homes, land, and countries. We must prevent the refugee crisis from growing at all costs. Climate change is not a “hoax”, it is a reality, and it is effecting us all. It is killing people directly and indirectly. It is killing our planet. This is why it is very important for us to all take part in slowing the effects of climate change. When the US began to reduce its waste, other countries followed suit.
Climate change is more than an environmental issue. It is a public health issue. It is an economic issue. It is a security issue. It is a racial issue.
There are many ways to reduce our carbon footprints and slow the climate change process; I will focus on four. First, reduce fossil fuel use. this may be something more for factories, it is important to know the effect that burning fossil fuels has on the environment, and the small things we can do to help reduce it. It can be reduced on the domestic level by using less electricity, and using more energy-efficient appliances. Converting from gas-powered appliances to electric can also have a large impact. Second, plant trees. Carbon dioxide is the most important greenhouse gas. Planting trees or any kinds of plants can aide in the conversion of carbon dioxide to oxygen. By planting trees, we are combating the effects of deforestation. Third, reduce your waste by recycling. The decomposition of garbage in landfills produces harmful gases like methane, which absorbs the sun’s heat, and increases the Earth’s temperature. Reducing your consumption habits and reusing or recycling items when possible largely decreases your carbon footprint, as it reduces the need for new items to be made, and prevents items from being placed into landfills. Recycling metals, plastic, glass, and paper helps decrease the greenhouse gasses from being emitted into the air, as it takes less energy to make an item from recycled materials than it does as opposed to making materials from scratch. In Birmingham, you can order a recycling bin by phoning 205-254-6314. Additionally, in Birmingham, the recycling center is located at 4330 1st Avenue South, Birmingham, AL 35222. Lastly, conserve water. The conservation of water is essential to the reduction of climate change. Water purification requires a lot of energy to complete, which in turn increases the mission of greenhouse gasses. By saving water, less energy is used. Turn off water at home when you are not using it, and pay close attention to pipes that may leak to ensure that unnecessary amounts of water are not used.
