The Environmental Impact of Carbon Dioxide (CO2)
Carbon Dioxide (CO2), a chemical made up of one carbon atom and two oxygen atoms, is a non-flammable, odorless and colorless gas that exists naturally in the atmosphere. CO2 is one of the greenhouse gases, amongst methane, nitrous oxide and other gases, which keeps the Earth’s temperature habitable (UCAR). Without it, the Earth will be inhospitably cold. However, ever since the mid-nineteenths century, humans have significantly increased the amount of CO2 emitted into the atmosphere, creating an imbalance. The gradual increase in CO2 concentration have been driving what is called global warming, which describes the current phenomenon of the increase in temperature of the Earth's surface and

However, since the Industrial Revolution began in 1750s, the discovery of utilizing fossil fuels have significantly increased the amount of CO2 emitted into the atmosphere, upsetting the balance (EPA). According to UCAR (University Corporation for Atmospheric Research), there was about 270 parts per million volume (ppmv) of CO2 in the atmosphere in the mid-19th Century, and now there is about 398 ppmv of CO2. This gradual increase have caused the greenhouse effect to strengthen, changing the Earth's climate, causing global warming.Carbon dioxide accounts for 72% of the warming effects of the emitted greenhouse gasses, therefore making CO2 emission a very significant cause of global warming. The main source of CO2 is the combustion of fossil fuels, which accounts for around 94% of the gas’s emission. In this process, the fossil fuels releases the carbon it contains into the atmosphere, which are compelled to combine with the oxygen molecules, creating carbon dioxide. Currently, the CO2 concentration in the atmosphere is rising at the rate of about one part per million per year. Meteorologists have estimated that the average temperature of the Earth will increase by 2.5 degrees celsius over the next century if this continues …show more content…
This includes resulting a change in weather. Emerging evidences shows that global warming is already causing heat waves, droughts, and intense precipitation. Overall, a more extreme weather pattern. Also, according to the Intergovernmental Panel on Climate Change (IPCC), sea levels are estimated to rise 1.2 meters by 2100 as glaciers melt and warming sea water expands. All of these changes will greatly impact the ecosystem, as all species have their natural habitats where they are able to co-exist and survive, and when the environment around them changes, they will have to migrate or adapt. If they are unable to do so quickly enough, the species will face extinction (NASA). For example, the shifting seasons have already cause the lifecycle of bees to fall out of sync with flowering plants. The mismatch have already caused around 30 percent of the bees to die off per year in the last decade (McDonnell). It is estimates by the IPCC that 20% to 30% percent of all species will be at risk of extinction over the next century if the temperature indeed increases by 2.5 degrees

    Over the past years, carbon dioxide has been at the center of debates in regards of the negative effects it has on the environment. CO2 is considered as a pollutant, it has the ability to turn fresh air into toxic air. Industries and automobiles are two of the major entities known to cause CO2 pollution. Automobiles emit CO2 by burning fossil foil for energy. The most frequent utilized fossil fuel worldwide are coal and oil. “Over 90 percent of the fuel used for transportation is petroleum based, which includes gasoline and diesel” (EPA). In addition to being a pollutant, CO2 is considered as a greenhouse gas. This means that it has high tendency to cause on climate change.…

    Carbon dioxide is the main pollutant that warms our planet Earth. Living things produce carbon dioxide when they breathe. However, carbon dioxide is considered to be a harmful pollutant when linked with any vehicle, trains, power plants, as well as other various human activities that involve burning fossil fuels such as gasoline and natural gas. Studies have shown that In the past 150 years, such activities have released enough carbon dioxide into the atmosphere to raise its levels higher than they have ever been before.…

    Climate change is one of the emerging issues for global environment. It may be defined as the long-term change in average weather conditions, including temperature, precipitation and wind. This is already apparent as evidenced by higher temperatures, rising sea levels, increased ocean acidity and ice melt. Global surface temperatures, alone, have increased by roughly 0.74 °C (1.33 °F) between the start and the end of the 20th century. Natural causes alone cannot explain all of these changes. Most of the warming of the past half century has been caused by human emissions of greenhouse gases. This gases act like a blanket or glass roof around the earth, trapping in heat that would otherwise escape to space – this is commonly referred to as the “greenhouse effect”. From the end of the last Ice Age about 10,000 years ago to the end of the 18th century, the levels of greenhouse gases in the atmosphere remained fairly constant and at a level sufficient to sustain life as we know it today. Since the Industrial Revolution 200 years ago, mankind has been releasing unprecedented amounts of greenhouse gases into the atmosphere, which trap more heat, amplifying the natural greenhouse effect. Carbon dioxide (CO2) is the most significant greenhouse gas released by human activities and is emitted mostly from the burning of fossil fuels like coal, oil and natural gas. Other greenhouse gases include methane and nitrous oxide. Without effective action to halt the rise and then reduce the levels of greenhouse gases released by human activity, countries worldwide and their citizens face significant changes in food and water resources, health and living standards as they are forced to adapt to a changing climate. It is predicted that society will face disruption from extreme weather, with more frequent storms and flooding, more severe droughts and heat waves, which will result in a loss of agricultural land and biodiversity. In many regions agriculture will be adversely affected by…

    This has been the warmest decade since 1880. In 2010, global surface temperatures tied 2005 as the warmest on record, according to the National Oceanic and Atmospheric Administration. Scientists say that the earth could warm by an additional 7.2 degrees Fahrenheit during the 21st century if we fail to reduce emissions from burning fossil fuels, such as coal and oil. This rise in average temperature will have far-reaching effects on the earth 's climate patterns and on all living things. Many of these changes have already begun. Increasing global temperatures are expected to disrupt ecosystems, pushing to extinction those species that cannot adapt. The first comprehensive assessment of the extinction risk from global warming found that more than 1 million species could be obliterated by 2050 if the current trajectory continues.…

    Carbon dioxide is naturally present in the atmosphere as part of the Earth 's carbon cycle. Yet human-related emissions are responsible for the increase in CO2 emissions. The use of electricity accounts for 37% of total U.S. emissions, while transportation 31%, industry accounts for 15%, residential and commercial 10%, and other non-fossil fuel combustion 6%. That is 99% of the total globe greenhouse gas emissions. Carbon dioxide (CO2) emissions in the United States increased by about 7% between 1990 and 2013. (EPA, 2015) Not leaving out pollution also a contributor of increases in anthropogenic CO2. These things are the cause of the earth heating up, or global warming. Trees and plants help soak up the CO2 in the atmosphere but with the tearing down of trees to build industry buildings, residential and commercial buildings there are fewer trees and plants to take in CO2 for photosynthesis.…
