The main source of the increased levels of carbon dioxide in the atmosphere is the burning of fossil fuels, causing 75% of the increase.

Secondly, together with deforestation of the planet, the burning of fossil fuels is contributing to a measurable increase in the concentration of carbon dioxide in

The major contributors to global warming are four types of greenhouse gases. (Fig. 2). These gases ultimately lead to the greenhouse effect. (Fig. 3). Carbon dioxide is essential to living because when a plant goes through photosynthesis, it is converting Carbon dioxide and water into oxygen that humans need to breathe. (UCSB, 2015) Although CO2 is essential for life, it can have harmful effects. Fossil fuels are any natural fuels that were formed on the Earth’s surface before humans existed. These natural fuels include: Coal, oil and natural gases. Humans have to burn these fuels in order to create vital essentials to life such as energy and electricity. Unlike plants, when we burn these fuels for electricity and energy, Carbon dioxide is released into the Earth’s atmosphere. These gases eventually trap the heat that is supposed to escape the Earth, thus creating higher temperatures on

A) Burning of fossil fuels-This is the most prominent and deadly source of climate change. Burning of fossil fuels can release greenhouse gases ranging from carbon dioxide to ammonia. With massive industrialization currently going on, the amount of fossil fuels burned is increasing. Transport and heating are also major energy sources. Almost 7 giga tonnes of Carbon dioxide is emitted per year. In the U.K three-fourths of energy produced comes from fossil fuels. Mineral fuels like petroleum and coal are major sources of energy. In the last 150 years more than 45 Billion tonnes of carbon dioxide has been emitted .The most problematic factor is that in the last decade; there has been no slowdown in carbon emissions.

Some of the most prevalent causes of CO2 levels in Earth’s atmosphere are the burning of fossils fuels, deforestation, and volcanic degassing. Fossil fuels are naturally formed fuels such as coal or natural gas that are formed by organic material such as plants. When fossil fuels are burned, the carbon that is locked in them is released into the atmosphere to bond to oxygen to form carbon dioxide. This CO2 has nowhere to go except into the air. There are some natural “sinks” that act as nets for greenhouse gasses. Forests and oceans are the largest sinks on the planet. CO2 is absorbed by plants to use for photosynthesis and when forests are cut down, the area available to take in CO2 excess decreases. The ocean can only hold so much CO2 and is currently holding approximately 1/3 of its’ limit. (Pickrell) Volcanic

Today carbon dioxide is the primary greenhouse gas emitted through human actives in the world. Carbon dioxide accounts for nearly three quarter of the greenhouse gas emission. The main source of carbon dioxide emission in the United States are electricity, transportation, and industry. Electricity has a significant amount of emission due to the fossil fuels needed to generate electricity, to power homes, businesses, and industries. The second largest cause of carbon dioxide emission is transportation. Transportation accounts for 31% total of carbon dioxide emission in the United States. Lastly industry is another large part in the emission rising. Many industry process carbon dioxide and the emission through chemical reaction that do not involve combustion. These are the leading carbon dioxide emission today in the world.

smog as well. Uncontrolled plants emit up to 10, 300 tons a year and those with controls

The earth is able to hold many types of gases and is capable of amazing things along with that. Carbon Dioxide is nonreactive with most of the things on earth so we hardly notice the increase in carbon dioxide levels that are occurring. With its non-reactivity it can slowly build up and the only way we will notice the increase of the carbon dioxide here is by the climate change here on earth. Although there many gases and other compounds that have an effect of the climate change, carbon dioxide seems to be the leading compound that is causing climate change on earth. From 1750 to 2005 carbon dioxide the radiative force of carbon dioxide had increased 1.6 which means it is causing the earth to get warmer. There are other gases that have more

However, molecules that are on average neutral (in terms of their electrical charge) can still have localized charges, either some of the time (when they are vibrating) or all of the time. Carbon dioxide is the second most important GHG, producing some 9% to 26% of the greenhouse effect. The carbon cycle describes the ways in which carbon moves through the Earth system; carbon dioxide in the atmosphere is just one of many aspects of the carbon cycle. Carbon dioxide concentration in the atmosphere is quite low; slightly less than 0.04%. It is usually described in terms of parts per million by volume (ppmv); the current value is around 383 ppmv. Natural sources of CO2 include volcanic outgassing, combustion of organic matter, respiration of living aerobic organisms, and fermentation by microbes. About three-fourths of anthropogenic CO2 emissions result from burning fossil fuels for heating, power generation, and transportation. Most of the rest of human CO2 emissions are a result of land use changes, especially deforestation. Processes that remove carbon dioxide from the air are called "carbon

Although many people assume the main cause of greenhouse gasses is the burning of fossil fuels, the main contributor is actually methane emissions produced by livestock. Animal agriculture produces 18% of the total

By driving vehicles, using plants that burn coal, humans are harming the natural system created by the earth. This is causing more CO2, methane, and nitrous oxide to be released. When nitrous oxide is in the atmosphere, it has a lifespan of about 114 years. Methane is approximately 12 years spent in the atmosphere. Carbon Dioxide is a little more difficult to determine its lifespan in the atmosphere due to there being several processes that remove it. About 80% of carbon dioxide is dissolved into the ocean, and can take between 20 and 200 years to do. The other 20% can stay in the atmosphere for possibly hundreds of thousands of years. Methane is created and released by fossil fuels, rice patties, waste dumps, and cow farms. Nitrous Oxide is created and released by the using of fertilization, industrialization, and combustion.

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).

Nevertheless, the cycling of carbon dioxide gas is impacted by both natural and human resources. Natural resources which cause carbon dioxide emission comprises decomposition, ocean release and respiration. The greater percentage of carbon dioxide emission gas is caused human activities including deforestation, mining, transportation, industries, land use, the burning of fuels, just to name a few.

The earth’s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the buildup of greenhouse gases –– primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed. Although uncertainty exists about exactly how earth’’s climate responds to these gases, global temperatures are rising. Go to the Emissions section for much more on greenhouse gases.

CO2 is one the gases in the greenhouse gas family and with “a stronger greenhouse effect [it] will warm the oceans and partially melt glacier and other ice, increasing sea level” (Climate Change). As humans continue to emit greenhouse gases into the air it is inevitable that sea levels will raise, temperatures will increase throughout the globe, and ultimately change the climate drastically damaging many ecosystems and impacting the way in which humans live on Earth. Many make the argument that the reason fossil fuels are the primary source of energy is due to their density amount of energy, but there is another source of energy that has energy even more dense than fossil fuels.
