Global Warming Has On Our Health Essay

Global Warming is a major world problem that we have but people don’t seem to realize that and it may end all life on earth as we know it. We are causing many problems to the earth that we don’t realize what we are doing we may think everything is ok but it’s not. Global warming is all our fault and we need to stop!

The biosphere consists of a compound infusion of gases; the main components are oxygen, nitrogen, and carbon dioxide. The concentration of these gases have been changing for many years. For the most part, this is influenced by human activity. In a persistent effort to improve the quality and longevity of life, humans (particularly in industrialized societies) have tendencies to negatively impact the environment, and at the same time, we strive to replenish what we have nearly depleted to balance the scale.

Global climate change is more than just raising the concentration of GHG’s in the atmosphere, it’s a serious health threat. Dr. Howard Koh, of the Harvard T.H Chan School of Public Health, has stated that global warming is a threat to human health because of an increase in respiratory and allergy aggravation,

In order to understand the issue of global warming (also referred to as climate change), you must first understand what it means and how it happens. Global warming is a result of a process known as the greenhouse effect, in which the light and heat from the sun are trapped in the Earth’s atmosphere by greenhouse gases; which subsequently raises the average temperature on Earth. The greenhouse gases responsible for this process are carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and tropospheric ozone, all of which are released into the atmosphere through naturally occurring processes (Warrick, R. & Farmer, G., 1990).

Certain threats to human health loom larger with rising temperatures. Extremely hot temperatures can cause heat illnesses and loss of life. Several vector borne diseases only occur in warm areas, and an increase in temperature could mean a spread of these diseases to larger areas. Also, warm temperatures can increase levels of air pollutants, including ozone, which can harm human health.

The burning of fossil fuels such as coal and oil, and deforestation over the last 200 years has caused the concentrations of heat-trapping "greenhouse gases" to increase significantly in our atmosphere. These gases prevent heat from escaping to space. Greenhouse gases are necessary in our lives as they help in keeping the planet 's surface warmer than it would otherwise be. But, as the concentrations of these gases continue to increase in the atmosphere, the Earth 's temperature is climbing above past levels (USEPA, 2014).

Climate change is difficult to communicate by its very nature. Greenhouse gases are invisible, and their accumulating effects (e.g., global warming, precipitation changes, and extreme weather events) can take years before they are felt. Worldwide warming trends are hard for the average person to detect amidst the variability of everyday weather and the causes are far removed, in both time and space, from the impacts. Climate change is thus an example of “hidden hazards”—risks that, despite potentially serious consequences for society, generally pass unnoticed or unheeded until they reach disaster proportions (Kasperson and Kasperson, 1991).

Certain gases released into the atmosphere block heat from escaping. Gases that remain semi-permanently in the atmosphere and do not undergo physical or chemical changes in response to temperature are described as “forcing” climate change while those gases that respond physically or chemically to changes in temperature are termed “feedbacks” (National Aeronautics and Space Administration (NASA), 2016). Known gases that contribute to the greenhouse effect (global warming) include water vapor, nitrous oxide, methane, carbon dioxide and chlorofluorocarbons (CFCs). As water vapor (the most abundant greenhouse gas) increases, the Earth’s atmosphere warms and the possibility of clouds and precipitation increases too. Nitrous oxide is produced by soil cultivation practices especially through the use of commercial and organic fertilizers, fossil fuel burning, nitric acid production and biomass burning. It is a powerful greenhouse gas. Methane is produced through natural sources and human activities. Some of which include the decomposition of wastes in landfills, agriculture and ruminant digestion and manure management. Carbon dioxide is released through natural processes such as respiration, and volcanic activities and through human activities such as deforestation, fossil fuel burning, and land use changes. Studies have shown that humans have

Global warming, or what is now called climate change, is caused by the sunlight coming through the Earth’s atmosphere, containing greenhouse gasses, and becoming cemented between the Earth’s crust and Ozone layer. This causes an uncontrollable heating in the territory between them (“Global Warming Science”). “Even though these greenhouse gases hold the heat from the sun the greenhouse effect is what keeps the Earth’s temperature suitable for life. Without the greenhouse effect Earth would be frozen and no one would be able to live on it” (“Global Warming- Britannica”). Many people believe that climate change is a myth and that it is not true due to the consequences are too harsh for a normal person to think of, the

Alteration of this natural barrier of atmospheric gases can raise or lower the mean global temperature of the Earth”(Greenhouse Gas).

In addition, human also partake in activities that help destroy the planet. Over the past century global warming trend is also caused by human expansion of the "greenhouse effect"- warming that occurs when the atmosphere traps heat radiating from Earth toward space. Gases in the atmosphere block heat from escaping. This is called the greenhouse effect. However, while greenhouse gases increase, the climate changes and result into effects that is dangerous to human health and ecosystems. The gases that have an influence on the atmosphere are water vapor, carbon dioxide and

gases are known to be contributing factors to global warming. This is a serious issue and

Scientists who believe in global warming say that global warming is the result of carbon dioxide and other air pollutants collecting in the atmosphere like a thickening blanket, trapping the sun’s heat which causes the earth to heat up. In fact, according to Amber Jenkins, site editor for "Global Warming: Vital Signs of the Planet," meteorologists at NASA (National Aeronautics & Space Administration) have reported that “Earth is the hottest it has been in at least 400 years, and possibly even the last 2,000 years. Studies indicate that the average global temperature has increased by approximately 0.5-1.0°F (0.3-0.6°C) over the last century” (Jenkins).

The issue of global warming should be on the list of our top priorities. Studies show that the average of global temperatures have risen since the Industrial Revolution began. Since the Industrial Revolution, human emissions has quadrupled the frequency of certain heat extremes and many scientists have warned that a failure to bring greenhouse gases under control could eventually lead to a 62-fold increase in extreme heat blasts (Gillis Justin A17). Most of the increase is due to human activities, especially the burning of fossil fuels and deforestation. These activities contribute to a build-up in carbon dioxide and other gases in Earth’s atmosphere. The Earth’s atmosphere is made of gases like nitrogen, carbon dioxide and oxygen. These gases act as a blanket that covers and gives us warmth, but once these gases such as carbon dioxide absorbs heat, but does not release it back into space in which causes the increase in global temperature. This is called the greenhouse effect because it only traps heat but does not release it.

Global warming is the constant increase of temperature in the earth’s atmosphere that is caused by the increase of carbon dioxide, chlorofluorocarbons, greenhouse gases and many other pollutants. Chlorofluorocarbons are any type of compounds of carbon, hydrogen, chlorine, and fluorine which are harmful to the ozone layer. Global warming can affect many things, one example is the rising of temperature which can result in different types of disasters like storms, heat waves, floods, and droughts. Global warming also causes Higher death rates, Dirtier air, Higher wildlife extinction rates, the increase of Acidic Oceans, and Higher seas levels. In this essay, I will provide information that will show how harmful global warming can be to not only the earth but to humans and animals, and what we can do to prevent it from increasing.
