Each year, over 7.2 billion tonnes of carbon dioxide is released into the atmosphere by human activity. That is the equivalent of 110 million airplanes all being in the air at once! These disturbing numbers are the foremost cause of global warming, and have been steadily growing over the past few decades. Global warming is caused by this recent surge of greenhouse gasses which consists primarily of carbon dioxide.
Carbon dioxide isn’t harmful to the atmosphere in the amount that is produced naturally from decaying trees, volcanic eruptions, etc., because the forests act as a natural recycling system. However, humans burning fossil fuels, demolishing forests, and using chemical fertilizers are causing an enormous surplus of carbon

The core purpose of carbon dioxide existing in the atmosphere is to trap the heat acquired from sunlight and not let it past the atmosphere. It’s because of the carbon dioxide in the atmosphere that Earth's atmosphere is warm enough to sustain human life. When there is a large increase in the proportion of carbon dioxide in the air, the quantity of heat caught by the carbon dioxide also increases. This in turn contributes to the total rise in the surface temperature of the earth. Due to this rise in temperature in ice in the Arctic is melting, which is causing the sea level to rise.
Dr. Leonard Berry from the FAU Climate Change Initiative stated that “The ocean has risen six inches over the course of the last twenty-five years” (“Water…” n.pag.).
A major contributor to global warming is fossil fuels. Fossil fuels are used for everything from generating electricity from turbines to powering vehicles. In the last few centuries the economy has been growing so rapidly that the need for energy from fossil fuels has reached new heights. Upon the burning of fossil fuels, numerous gases like carbon dioxide, methane, nitrous oxide, etc., are released. A substantial amount of carbon dioxide being released into the atmosphere is from the burning of fossil fuels. Evidence acquired from several studies report that since the early nineteenth century, there has been over a 30 percent increase in the carbon dioxide content in the atmosphere.
Consider the following information: Every time we use fossil fuels, we release carbon dioxide into the atmosphere. Fuel must be burned to extract oil from the ground and process it; and then more fuel must be burned just to transport the fuel to where we buy it! Scientists believe that it is carbon dioxide emissions that are responsible for climate change, specifically the global warming effect.
The main source of the increased levels of carbon dioxide in the atmosphere is the burning of fossil fuels, causing 75% of the increase.
Main Point - Despite the fact that a specific amount of carbon dioxide (CO2) happens naturally in the Earth's atmosphere, there are many human activities that boost the levels of the greenhouse gases causing it to be harmful to Earth`s climate.
Carbon dioxide is very important in the atmosphere, however only in moderation. For centuries humans have been burning coal, oil, and fossil fuels therefore releasing tons of carbon into the air. The problem with this is that this can cause a problem known as global warming. This is a major climate problem, which has series results on people and the environment. The result on people can be very deadly. Too much carbon in the air can cause cancer.
The result is that humans are adding ever-increasing amounts of extra carbon dioxide into the atmosphere. Because of this, atmospheric carbon dioxide concentrations are higher today than they have been over the last half-million years or longer.
Carbon Dioxide is a dangerous, poisonous gas, carbon dioxide is a greenhouse gas that is appearing more in the atmosphere. The human body and most other species on earth need oxygen to live and breath. Without enough oxygen in the air we would suffocate and so would most other spices. Now there is a way to reverse the amount of CO2 in the air. The answer to this issue, is plant more trees! Trees and other vegetation take in CO2 and convert it to oxygen. Not only could we have CO2 levels on the rise but another big kill around the world is cancer is In 2012, there were an estimated 8.2 million deaths from cancer in the world. Cancer is the second leading cause of death around the world. Im
Every time we burn fossil fuels such as gas, coal or oil, carbon dioxide is released into the atmosphere. Naturally, carbon dioxide (CO2) is absorbed by plants and trees and exceeded as oxygen. However, humans are burning fuels quicker than the plants and trees are able to soak them up.
The combination of these and other trends was an estimated average sea-level increase of 1.5mm per year between 1961 and 2003, which reached 2.4mm per year in the decade from 1993 to 2003. The decades prior to this trend showed only minor fluctuations in sea-level, suggesting that the current rate exceeds what could be caused by natural cycles. While the exact impact of rising oceans is difficult to determine, it is certain that the consequences will include some degree of flooding, integration of salt water into water tables, and a loss of land due to coastal erosion and submersion.6
Recent scientific evidence indicates that humans have upset the carbon cycle, leaving more carbon dioxide and other greenhouse gases in the atmosphere. Burning fossil fuels such as oil and natural gas, burning biomass such as ethanol and wood, creating cement and releasing other chemicals into the atmosphere is upsetting the natural flow of carbon.
Every year, almost 7 billion tons of carbon dioxide is released into the atmosphere by human activity. That is the equivalent of 107,700,000 jet airplanes being in the air at once! This harrowing figure is the main cause of global warming, and has been increasing for the last 50 years. Global warming is caused by the increase of greenhouse gasses, carbon dioxide and methane primarily, in the earth's upper atmosphere directly caused by human burning of fossil fuels, industrial, farming, and deforestation activities. Global warming is defined as an increase in the average temperature of the earth's atmosphere (especially a sustained increase that causes climatic
“CO2 gas emissions” is a mystical term which everyone should pay attention to. C02 gas is a colorless, odorless gas that is present in the atmosphere and is formed when any fuel containing carbon is burned. Plants and trees are using it in the process of photosynthesis. Carbon dioxide is also used in refrigeration, fire extinguishers, and carbonated drinks. In other words this is the gas we need to fight with! By using fossil fuels in almost everything we do, we make a huge cloud of gas and this is warming up the world. By doing this, we cause serious damage to the nature and we may have an irreversible effect on it and the future.
The United States releases twenty tons of carbon monoxide per person per year. Carbon Monoxide release is a result of burning fossil fuels with an insufficient amount of oxygen that causes the formation of carbon monoxide that pollutes our environment. Everyday fuel is burnt by cars, airplanes, large factories and manufacturing plants. This is causing a very large and deadly problem for our environment. When gases used on earth are released into the atmosphere they act as a blanket and trap radiation that is then redirected to earth. This concept is called the Greenhouse Effect (Bad Greenhouse, 1).
Carbon dioxide is the greenhouse gas naturally found in the atmosphere. Since the advent of the Industrial Revolution in the 1700s, humans have devised many inventions that burn fossil fuels such as coal, oil, and natural gases, which, along with other human activities such as clearing land for agriculture or urban settlements, help some of these greenhouse gases accumulate in the atmosphere that in turn trap more heat radiation in the atmosphere causing the Earth’s climate to become warmer than it would naturally (Mastrandrea). This unnatural phenomenon is termed global warming by scientists and they blame it for an increase in the Earth’s surface temperature of about 0.6°C (about 1°F) over the last 100 years (Mastrandrea).
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.
Deforestation, the cutting and burning of a forest, also increases the amount of carbon dioxide into the atmosphere. A NASA page says that “when a forest is cut and burned to establish cropland and pastures, the carbon that was stored in the tree trunks (wood is about 50% carbon) joins with oxygen and is released into the atmosphere as CO2. CO2, is, of
