Global Warming Essay

What is the main source of the increased levels of carbon dioxide in the atmosphere?

When the atmosphere is warmed it emits IR radiation, with a portion of the energy acting to warm the surface and the Earth?s atmosphere. As a result the average surface temperature of the Earth is higher than it would normally be without the atmospheric absorption and re-radiation of IR energy. This is known as the ?Greenhouse effect?. The predictions of the future of these greenhouse gasses being in our atmosphere is based on how much we put into the atmosphere and how much is consumed. One thing is for certain, there are still large controversies on how much of these gasses that are let into the atmosphere are by natural or man made processes. (2-453-454)

The greenhouse effect on earth results from a higher concentration of carbon dioxide, water vapor and methane in the atmosphere.

Carbon dioxide (CO2) is a type of odorless and colorless gas that can be either manmade or naturally made. Carbon dioxide is a vital greenhouse gas; in moderation. Since the beginning of the Industrial Revolution, the concentration of carbon dioxide has increased significantly. The concentration of carbon dioxide in the air is leading to global warming, ocean acidification and a multitude of many problems. In a report released from NASA, the scientist state that “that human-made carbon dioxide (CO2) continues to increase above levels not seen in hundreds of thousands of years: currently, about half of the carbon dioxide released from the burning of fossil fuels remains in the atmosphere and is not absorbed by vegetation and the oceans”. The current assessment of carbon dioxide in the air is 402 parts per million (ppm). One PPM is equivalent to one microgram/one kilogram (0.6 of a mile). Scientist claims that it needs to be brought down to 350 ppm to even start

These gasses trap warmth and reason the planet to warm through a procedure called the greenhouse effect. Since 1751 around 337 billion metric huge amounts of CO2 have been discharged into the climate from the using of fossil fills and concrete generation, expanding air CO2 from the pre-mechanical level of around 280 ppm (parts per million), to a high of 400 ppm in 2013. Methane, which is expanding in the climate because of farming and fossil fuel use, traps 84 times as much warmth as CO2 for the initial 20 years it is in the environment, and is in charge of around one-fifth of a dangerous atmospheric climate change since 1750. Nitrous oxide, fundamentally discharged through farming practices, traps 300 times as much warmth as CO2. Over the twentieth century, as the convergences of CO2, CH4, and NO2 expanded in the air, the earth warmed by pretty nearly 1.4°.

Five gas molecules that attribute to the Greenhouse Effect are: Water Vapour (H2O), Nitrous Oxide (N2O), Methane (CH4), Carbon Dioxide (CO2) and Chlorofluorocarbons (CFCs). Carbon Dioxide is the most significant of these gases. This is because it is the most common of all the gases and acts as a very effective blanket to keep heat trapped in the Earth’s Atmosphere. Nitrous Oxide and Methane act in similar ways, but to a lesser extent since they aren’t produced as much. Water Vapour is also abundant like Carbon Dioxide, and it increases as the Earth’s temperature does due to the process of evaporation. This

Scientists attribute a huge percentage of the gas accumulation to the human activities using fossil fuels and whose operation leads to the release of significant amounts of carbon dioxide and other toxic gasses into the air. The rate of temperature rise since the industrial revolution shows a significant change of 38% due to the constant emission of toxic gasses from human activity (Lonnie, 153).

3. Methane is a colorless, odourless and non-poisonous gas. Its vapors are lighter than air and is slightly soluble in water but fairly soluble in ether and alcohol [5].

Carbon dioxide is one of the major greenhouse gases, and is one of the most common gases found in the earth’s atmosphere. Carbon dioxide is released into the atmosphere in mass amounts by human activities and then absorbed by our oceans. The main way that carbon dioxide is added to the atmosphere is by the burning of fossil fuels and deforestation. Increased energy composition and with the industrialization age, beginning in the 18th century, has led to a drastic spike in the burning of fossil fuels and therefore the release of carbon dioxide into the atmosphere. The main emitters of carbon dioxide are cars, airplanes, and factories

From the ‘age of dinosaurs’, some 200 million years ago (mya), methane - a greenhouse gas many times more potent than carbon dioxide - lay sequestered, safely locked away from the atmosphere three kilometers down in shale, two in sandstones, and one in coal seams, as life evolved overhead.

• Carbon dioxide (CO2) is a greenhouse gas that warms the atmosphere. • Since pre-industrial times, atmospheric CO2 concentrations have increased from about 280 parts per million (ppm) to over 380 ppm. Current concentrations of CO2 and other greenhouse gases are unprecedented in at least the last 650,000 years, based on records from gas bubbles trapped in polar ice. • Independent measurements demonstrate that the increased CO2 in the atmosphere comes

Light radiates from the sun into the Earth’s atmosphere and then to its surface in the form of solar or short wave radiation. The Earth’s surface then re-radiates the heat from the sun’s light back into the atmosphere in the form of infrared or long wave radiation. However, the infrared radiations do not easily penetrate beyond the Earth’s atmosphere because certain gases, called greenhouse gases, trap these radiations in the atmosphere. These greenhouse gases include carbon dioxide, methane, water vapor, and ozone. When the greenhouse gases in the atmosphere traps the infrared radiations, heat is released, and global warming results.

Humans are polluting our atmosphere causing the Greenhouse Effect.  What’s the Greenhouse Effect?  “The Greenhouse Effect can be visualized as follows: imagine that Earth has been encircled by a giant glass sphere.  The heat of the sun penetrates through the glass.  Some of the heat is absorbed by the Earth, and some is radiated back towards space.  The radiated heat reaches the glass sphere and is prevented from dispersing any further”(Global Warming The Facts).  This makes the heat bounce back towards the Earth, which heats it up tremendously.

Energy from the sun drives the earth’’s weather and climate, and heats the earth’’s surface; in turn, the earth radiates energy back into space. Atmospheric greenhouse gases (water vapor, carbon dioxide, and other gases) trap some of the

Greenhouse gases are compounds in the atmosphere that can trap and hold extra heat, which increases the temperature in the atmosphere. Greenhouse gases is the cause of the greenhouse effect that leads up to global warming. The greenhouse effect is the trapping of the sun’s warmth in the lower atmosphere that is due to the visible radiation from the sun. The solar radiation reaches the Earth’s atmosphere, then the rest of the sun's energy is absorbed by the oceans and lands which result in the heating of the Earth. After that the heat from the Earth goes towards space, some of the heat is trapped in the atmosphere by greenhouses gases which make the Earth warm enough to tolerate living life. The burning of fossil fuels and land clearing start to increase the number of greenhouse gases which travels into the atmosphere. The result of trapping extra heat cause the Earth’s temperature to rise. Scientist's has proven that the constant increase of heat in the atmosphere is caused by humans. The reason humans are proven guilty for the increase of global warming is because of the amount of carbon that is put into the atmosphere. Carbon is released from burning coal, oil, and gas or cutting down and burning forests. Carbon (CO2) is known as the main source of heat-trapping gas which is mainly responsible for the increase of warming over the years. The removal of trees is another cause of global
