The molecular formula of carbon dioxide is CO2. Carbon dioxide is a naturally produced nontoxic gas that has no smell. Carbon Dioxide is the most abundant greenhouse gas on the planet next to water vapor. In solid form it is commonly known as dry ice. It is a gas that is mandatory to the survival of most, if not all, living organisms on this planet. Terrestrial animals naturally create carbon dioxide in their lungs when the breathe out Humans alone do not physically or directly need carbon dioxide to survive though. Humans need carbon dioxide to survive because it feeds the plants which produce oxygen for us to breathe. Carbon dioxide in the atmosphere also allows for a warmer temperature so that conditions on Earth allow it to be inhabitable. Today we hear that carbon dioxide in the atmosphere is becoming a problem even though it is a naturally occurring gas. This is because humans have been interfering with the natural cycle of carbon dioxide.
Carbon dioxide is created through many different processes, both natural and unnatural. It is created through respiration, the burning of fossil fuels, the burning of wood, and many other ways. Carbon dioxide is absorbed by many different things. For example, plants absorb carbon dioxide through photosynthesis. However, the soil releases some carbon dioxide back into the air. The ocean has a similar process. The ocean absorbs carbon dioxide that falls into the water and some is released through evaporation. Most of the carbon dioxide emissions actually come from the generation of electricity. 38% of carbon dioxide emissions in the United States comes from the burning of fossil fuels like coal to heat up water in order to power steam powered turbines. This generates electricity. The next...

...of agricultural supply. This theory is similar to people being born because the quality of life slowly begins to degrade as more carbon is put into the atmosphere. The quality of life will degrade because too much carbon dioxide is dangerous to both plants and animals. If we look at Venus today, it is further from the sun than Mercury but yet somehow seems to be much hotter. This is because the atmosphere is much thicker than Mercury’s. An extreme amount of carbon in the atmosphere of Venus is what makes the temperature so high. The temperature of Venus is approximately 864 degrees Fahrenheit and Mercury is approximately 800 degrees Fahrenheit. This is all while Mercury is closer to the sun than Venus. If carbon dioxide is put into the atmosphere at the rate it currently is, then it is only a matter of time before Earth’s atmosphere becomes like Venus’ atmosphere.
Carbon Dioxide (CO2) is a colorless gas, which was first discovered in 1577 by Van Helmont who detected it in the products of both fermentation and charcoal burning. CO2 is used in solid, liquid, and gas forms in a variety of industrial processes. These include: beverage carbonation, dry ice, welding and chemicals manufacturing. It is produced by the combustion of all carbonaceous fuels and can be recovered in an abundance of ways. It is widely used today as a by-product of synthetic ammonia production, fermentation, and from flue gases by absorption process. CO2 is also a product of animal metabolism and is important in the life cycles of plants and animals. It is present in the atmosphere only in small quantities (.03% by vol.)
Antarctic’s ice melt and accelerating sea level rise, the growing number of large wildfires, intense heat wave shocks, severe drought and blizzards, disrupted and decreased food supply, and extreme storm events are increasing to happen in many areas world wide and these are just some of the consequences of global warming. The fossil fuel we burn for energy coal, natural gas, and oil plus the loss of forests due to disforestation, in the southern hemisphere are all contributors for climate change. In the past three decades, every single year was warmer then the previous year and the warmest 12 years were recorded since 1998. We are overloading our atmosphere with carbon dioxide and trapping the heat and recently, the carbon dioxide level in the atmosphere reached 400 pmm. Not just environmental issues are rising due to carbon dioxide increase but more and miscellaneous issues are appearing as climate change becomes more severe. For example, regional models and local analyses agree that Mongolia has become noticeably warmer and the climate change effect is damaging their millennial of historic nomadic lifestyle and even came to the peek of extinction. The Mongolian nomadic pastoralists became highly vulnerable to many an unusual climate impacts and extreme temperature fluctuation that have led to inadequate pasture land and loss of enormous number of livestock, often faces hostile environmental conditions that led o entrenched pastoral poverty. This essay focuses on how the climate change impacts the qualitative and quantitative value of indigenous culture and nomadic life style, and how the economy struggles in the magnitudes of massive migration of nomads to urban area while it fails to value t...
From Venus’s atmosphere, we can see that a stronger greenhouse effect would create a barren, volcanic wasteland unable to sustain life. Such a greenhouse effect could even be man-made through the human production of CO2 and Earth has already noticed a greenhouse effect forming, though it is much less damaging than Venus’. Similarly, Mars’ lack of an ozone layer shows us what our own thinning ozone layer could mean for hydrogen atoms within Earth’s atmosphere and water, and also demonstrates how a planet’s size and distance from the sun could have affected Earth and made life on it impossible. Through the thinning of our atmosphere, Earth could suffer from the same effects plaguing its neighbor, Mars
Mankind’s industrialization of the world has caused a drastic increase in temperature. This rise in temperature is caused by solar radiation remaining in our atmosphere because of gases produced by humans through the burning of fossil fuels, land clearing, agriculture, and other human activities. These gases block the radiation from escaping into space therefore warming our planet. The result is raising of ocean levels, extinction of species and threatening of children’s health because of disease and less freshwater to drink. While many view climate change to be a more natural occurrence than others do, scientists have proven the average temperature rise of the Earth between 0.4 and 0.8 °C over the last 100 years.
When people burn fossil fuels to accumulate and produce energy a substance called carbon is produced. Carbon is released into the air in a form known as carbon dioxide. Carbon moves throughout the biosphere on the planet as it is recycled and reused. Carbon exists in the earth’s atmosphere in two common forms which are methane and carbon monoxide. These gases absorb and retain heat in a process known as the greenhouse effect. The Planets natural greenhouse effect makes life possible by regulating our temperature. It turns out that adding too much to the greenhouse effect can have horrible consequences on the environment. Each year, five and a half billion tons of carbon is released by burning fossil fuels and of that three billion tons enters the atmosphere. The remaining carbon usually gets absorbed by the oceans.
Over the course of recent history, much concern has been raised over the industrial revolution and the potential climate changes that it might be causing. It has been stated by global warming theorist that C02 emissions caused by human technologies are causing the world to warm, which will cause negative climate changes. The Earth may be experiencing a global warming trend and climate change; however, the process of climate change is outside of human control because human activity can barely account for any of the C02 level increases. Attempts to reduce human C02 emissions is needlessly expensive, and will have a negligible role in preventing or slowing any climatic changes such as global warming or an impending ice age. People must be prepared to adapt to the climatic changes that occur, because it is unlikely that human intervention will postpone them or limit the impact of their arrival.
Carbon dioxide or CO2 is known to be one of a number of gases that are astonishingly transparent to the visible light that falls on the Earth from the Sun, but it absorb the infra-red radiation that emitted by the warm surface of our Earth, to prevents its loss into space. Moreover, CO2 has varied considerably and this affected the Earth’s temperature. Most common source of this CO2 is known as the fossil fuel. Fossil fuels are primarily coal, hydrocarbons, natural gas, or fuel oil that formed from the remains of the dead plants and also animals. The burning fossil fuel that has been created by humans is the largest source of emissions of the carbon dioxide.
Air pollution and greenhouse gases are the reason for the planet as it is today; the reason why we see campaigns flooding the media informing us to ‘switch off’, ‘save the planet’ and ‘turn down the heat’ and the reason why the government is trying to develop a successful scheme, such as the carbon tax scheme, to reduce air pollution caused by major industries. Air pollution and greenhouse gases are the two immediate causes of global warming and climate change. Air pollution occurs when chemicals or particulate matter enter the atmosphere. They can cause damage to living organisms on the planet, as well as destruction to the natural and synthetic environment (Energy Environment.net 2008). Greenhouse gases are gases in the atmosphere that absorb infrared radiation emitted from the earth. They trap infrared radiation in the form of heat, and hence contribute to global warming. Anthropogenic greenhouse gases are a direct result of air pollution. They are the physical gases emitted that cause air pollution. Naturally occurring greenhouse gases also have an influence on the earth’s atmosphere, though it is not as conspicuous as anthropogenic causes. Together, air pollution and greenhouse gases are intensifying climate change and global warming on a world-wide basis.
The emission of carbon dioxide has contributed to 80% to the heating of the earth atmosphere. Carbon dioxide is produced due the burning of fossil fuels such as natural gas, coal and oil. The burning of fossil fuel is very important in our society today, because it is used for cooking, used to produce electricity, for heating, for cooling and also for transportation. The industrialization has led to the use of fossil fuel for running machines and driving cars. The building of fossil fuel contributes towards 80-90% of the carbon dioxide we find in our atmosphere today. When the ecosystems are altered and vegetation is either burned or took out, the carbon stored in them is relinquished to the atmosphere as carbon dioxide (What causes global climate change, 2005). Methane is another gas being produced in the process which all have served to increase the greenhouse effect in our atmosphere. Methane is produced from the cultivation of rice, from the burning of coal and from cattle, it has increased by 145% due to human
The commonly debated “greenhouse effect” refers to “the global average temperature increase that has been observed over the last one hundred years or more” (Spencer). President Barack Obama addressed the issue in an effort to highlight its severity, "We have to all shoulder the responsibility for keeping the planet habitable, or we’re going to suffer the consequences – together” (Leader). The earth’s increasing atmospheric and oceanic temperatures result in climate changes due to cumulative amounts of carbon dioxide (CO2) in the atmosphere. As an outcome, researchers around the globe have established that the by-product of burning fossil fuels is the main culprit of the increasing temperatures. Global carbon emissions from fossil fuels have significantly increased since 1900, as shown above from a study carried out by the Carbon Dioxide Information Analysis Center.
Carbon Dioxide is a colorless, odorless gas that occurs in small quantities in the earth's atmosphere naturally. The earth's ocean, soil, plants and animals release CO2. The formula of Carbon Dioxide is CO2. The CO2 molecule contains 2 oxygen atoms that each share 2 electrons with a carbon atom to form 2 carbon - oxygen double bonds. The atoms are arranged as so (OHT). This is called a 'linear molecule'.
This “greenhouse effect” on Venus happened completely naturally, however the greenhouse effect that we see happening on Earth is ultimately man made. Yes, Co2 is found on Earth at natural levels due to volcanic eruptions and it is what living things exhale, however there is a difference between natural Co2 and burned fossil fuels, the Co2 emitted from volcanic activity is slightly heavier and only makes up two percent of the thirty billion tons made by human activity each year (Tyson). While Co2 is naturally occurring on the Earth, our burning of fossil fuels are causing the Co2 levels to spike, which can have a terrible and irreversible outcome if we do not fix it soon. The climate change that the Earth is experiencing is undeniable, it is important to understand the factors that affect climate change, the repercussions if it is ignored, and how we can prevent it from happening at

Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased evacuation of greenhouse gases. “Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface while long-wave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases.” (2)
The carbon dioxide, also known as a greenhouse gas, remains in the air trapping heat and gradually warming the planet. Other greenhouse gases such as: methane, nitrous oxide, and water vapor also contribute to this slow warming. According to Live Science, The state of these gases being trapped is called the greenhouse effect, which is one of the leading causes of global warming (Lallanillia). All the gases are created differently and have different effects on the earth.
