In the world today, global warming and climate change are one of the main issues with the earth. This issue affects everyone and everything in this world, and even though it seems to be a big problem, most people do not seem to care. The most familiar term is global warming and climate change, but greenhouse gases is one of the main causes and is never mentioned. Greenhouse gases are gases that absorb and emit radiation in the atmosphere, hence makes the earth warmer. The importance of this knowledge of greenhouse gases is so the world will know one of the main causes of global warming and climate change and possibly some
Greenhouse gases keep heat close to the earth’s surface making it liveable for humans and animals. However, global warming is happening largely due to an over-emittance of these gases and fossil fuels (natural oil, gasoline, coal)
The Sun is responsible for all of the energy that enters the Earth’s atmosphere. The Earth 's energy is in balance when Earth emits the same amount of energy as it absorbs (Schneider, 1987). But today, the Earth is absorbing more energy than is what is being released due to increases in greenhouse gases in the Earth’s atmosphere (Herbert, 2007). Out of the total energy entering the Earth’s atmosphere, as seen in Figure 1, only 30% is being reflected back into space due the Earth’s albedo (Schneider, 1987). The other 70% of this energy is being absorbed by the Earth’s surface and atmosphere (Schneider, 1987). Here we are going to discuss how increasing greenhouse gas concentrations leads to climate change, some consequences that come with climate change and what can be done about it.
Global warming is caused due to the presence of the gasses in the atmosphere, mainly carbon dioxide, methane, chlorofluorocarbons and nitrogen oxide
a) Greenhouse effect is the direct natural result of Sun powering climate on the Earth. Sun’s radiation is passing through the Earth’s atmosphere which in turn causing the Earth’s surface to warm up. As an estimation, about 30% of the solar energy is bouncing back to the space as a results of the Earth’s atmosphere. The other 70% of solar energy is attracted by the Earth’s surface and atmosphere. In order to create a balance, Earth has to reflect this extra amount of energy back to space but, part of this reflection is absorbs by Earth’s atmosphere and will be sent back to Earth. This process is warming up the Earth’s surface and prevents the temperature on the Earth’s surface to drop below zero Celsius degrees. This is called natural Greenhouse effect but, due to various human activities such as deforestations and fuel burning and other factors have exacerbate this natural process of Greenhouse effect in which created the global warming . The primary greenhouse gases are water vapor (H2O): from the water on the Earth’s surface. Carbon Dioxide (CO2): its increase in the atmosphere is due to the fuel burning process. Methane (CH4): its increase in the atmosphere is due to several reasons such as melting permafrost, landfills generate CH4, and when ocean temperature rises causes release of Methane. Nitrous Oxide (N2O): agriculture and soil cultivating cause increase in the amount of N2O in the atmosphere. Chlorofluorocarbon (CFC): released to the earth’s atmosphere
There are four major gases that cause the greenhouse effect. These chemicals are Chloroflourocarbons (CFC’s), Nitrous Oxide (N2O), Carbon Dioxide (CO2), and Methane (CH4). “CFC’s destroy ozone molecules by the thousands, causing a smaller amount of ozone in the ozone layer. This allows more UV rays hit the Earth’s surface, causing a slight increase of the Earth’s temperature. The more ozone molecules destroyed, the more UV rays enter the Earth’s atmosphere, making the temperature even higher”(What Is The Greenhouse Effect).
To begin with, it is important to discuss the common causes of climate change. The most prominent and well-known cause is what is known as the “Greenhouse Effect.” The effect is the result of various gases becoming trapped within the Earth’s atmosphere, which alters the reflection and absorption of sunlight. As the levels of the gases increase in the atmosphere, more sunlight is absorbed, causing warming of the Earth. These “greenhouse gases” include carbon dioxide, methane, nitrous oxide, and “F-gases.”
Many climate scientists accept the main source of the existing global warming is human increase of the “greenhouse effect”. The greenhouse effect is a natural course that heats the Earth’s surface. When the energy of the sun reaches the Earth’s atmosphere, some of it is reflected to space and the rest gets absorbed by the land, ocean, greenhouse gas. Now the absorbed energy heats up the surface of the Earth and atmosphere to maintain Earth’s temperature and make the planet habitable, however, in the current atmosphere, the problem is human activity
The greenhouse effect plays an essential role in preventing the planet from entering a perpetual ice age: Remove the greenhouse gases from the atmosphere and the earth’s temperature would plummet by around 60 degrees Fahrenheit (F). However, scientists who have elaborated on Arrhenius’s theory of global warming are concernced that increasing concentrations of greenhouse gases in the atmosphere are causing an unprecedented rise in global temperatures, with potentially harmful consequences for the environment and human health.
It is widely agreed that the most relevant greenhouse gases emitted into the atmosphere are: Water Vapor (H2O), Methane (CH4), Nitrous Oxide (N2O), Ozone (O3), and most commonly, Carbon Dioxide (CO2). What needs to be made known is, air spreads worldwide, and globally-speaking there is no place/country with significantly more greenhouse gases than another does (EPA). All humans are subjected to the same amount of global warming, even if one lives in an area that does not release much greenhouse gas in comparison to a country like the United States.
Global Warming is caused by extreme quantities of greenhouse gases emitted into Earth’s near-surface atmosphere, (Deborah White). Greenhouse gases are produced by both man and occur naturally. These gases consist of carbon dioxide, methane, nitrous oxide, chlorofluorocarbons. These gases are what cause global warming or the greenhouse effect. Carbon dioxide is produced by volcanic eruptions, natural fires, fossil fuel combustion, deforestation and land use changes (such as converting forests to urban development. Methane is another greenhouse gas which is produced by the decay of organic substances in landfills, wetlands, and rice fields; also enteric fermentation in the digestive tracts of ruminant animals. Nitrous Oxide is produced by the use of
Another important point the author explained in his article is the Greenhouse effect and its contribution to global warming. Earth’s atmosphere acts as this blanket because it contains small amounts of carbon dioxide methane nitrous oxide and other gases in the atmosphere known as greenhouse gases. These gases help retain heat through a vital process called the greenhouse effect. The greenhouse effect occurs when sunlight passes through the atmosphere and strikes the earth some of the light is reflected and some is absorbed, and that absorbed light warms the surface of the earth. This is a natural process that is required to keep planet sustainable. Without the greenhouse effect, the Earth would be too cold for human beings, or any other living thing, to survive. Due to the burning of large amounts of coal oil and natural gas, the amount of greenhouse gases in the atmosphere has
The greenhouse effect is what allows life on Earth and the atmosphere contains trace gases which are designed to retain heat. The gases that are present in the atmosphere are water vapor, carbon dioxide, methane, ozone, and nitrous oxide. These gases act as a global insulator and help control the Earth’s atmosphere. It all begins with sunlight which is a form of energy that is mostly absorbed by land, oceans, and a portion of the sunlight is reflected back to the atmosphere. Once the earth warms up, it then gives off energy in a different form which is called infrared radiation or electromagnetic radiation. The planet need some of the greenhouse gases because without them the
These Greenhouse gases mainly consist of water vapour. As we know, this isn’t directly caused by humankind in significant amounts. However, any increase in the atmospheric levels of carbon dioxide can cause a substantial increase in the Earth’s temperature. And guess whose fault this is: ours. Human beings have risen the CO2 concentration levels by 30%, which is an extremely
Earth’s temperatures are largely determined by the balance between the amount of sun energy entering the atmosphere and the amount of energy lost from the earth into space. The natural greenhouse effect is a band of gases that trap heat emanating from the planet’s surface. These gases are water vapour, methane, nitrous oxide, chlorofluorocarbons, tropospheric ozone and mainly carbon dioxide. These gases allow visible sunlight energy to penetrate deep into the atmosphere; they are then absorbed by oceans and land masses. When this stored energy is released back to space as infrared radiation and heat, the greenhouse gases act as an insulating blanket in helping to maintain warm temperatures needed for basic human survival. This is what scientists call the “greenhouse gas effect” Without it; scientists estimated that our planet would be 35 degrees cooler than usual, which would be too cold for an eco-system to sustain. We are contributing to the release of these greenhouse gases by burning waste, wood products, and fossil fuels that emit carbon dioxide into the atmosphere. Our farmers use synthetic fertilizers that emit nitrous oxide and methane is produced in our processes of composing waste in landfills, and last but not least the natural population growth increases our usage of these greenhouse gases when there
