DATA ANALYSIS PROJECT
THE RELATIONSHIP BETWEEN CARBON DIOXIDE AND ANNUAL MEAN TEMPERATURE IN THE U.S.

Date: 05/10/2013 I Background
There is one of the most sensitive global climate issues for years, which is global warming. In general, we know that the origin of global warming is the emission of Carbon Dioxide. It was verified that the relationship between Carbon Dioxide and temperature: when there is more Carbon Dioxide the temperature gets warmer.
According to the 2007 Fourth Assessment Report by the Intergovernmental Panel on Climate Change, global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 20th century (Keppler). Because of the tendency of rising temperature during 20th century, we step forward and collect more data from 1990 to 2009, which is more representative for us to find out the relationship between Carbon Dioxide and Annual Mean Temperature, especially in the U.S. II Questions * Is there a relationship between Carbon Dioxide Emissions and Annual Mean Temperature in the U.S.? * If there is, whether the relationship is positive or negative? III Analysis
Data collected below is the Carbon Dioxide Emissions and Annual Mean Temperature in the U.S. from 1990 to 2009. Year | U.S. Carbon Dioxide Emissions | U.S. Annual Mean Temperature | 1990 | 5040.9 | 53.16 | 2000 | 5900.3 | 53.57 | 2004 | 6031.3 | 54.12 | 2005 | 6055.2 | 54.63 | 2006 | 5961.6 | 53.42 | 2007 | 6059.5 | 54.66 | 2008 | 5865.5 | 53.31 | 2009 | 5446.8 | 53.39 | 1. Analysis 1: Scatterplots & Correlation
Pair the data into the order of (x, y), which x value represents the value of U.S. Carbon Dioxide Emission and y represents U.S. Annual Mean Temperature. (5040.9, 53.16) | (5900.3, 53.57) | (6031.3, 54.12) | (6055.2, 54.63) | (5961.6, 53.42) | (6059.5, 54.66) | (5865.5, 53.31) | (5446.8, 53.39) | Input all the data into TI-84 Plus

The second cause of global warming is attributed to man. Human activities such as burning fossil fuels have contributed greatly to global warming. When these fuels are being burned, toxic gases are being released into the atmosphere such as carbon dioxide. When these gases are released, the solar energy is trapped which automatically causes the temperature to increase.…

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…

Greenhouse Gases: Carbon dioxide (CO2) is a greenhouse gas in the atmosphere that may raise average temperatures on Earth. The burning of fossil fuels could be responsible for the increased levels of carbon dioxide. If current trends continue, future concentrations of atmospheric carbon dioxide in parts per million (ppm) could reach the levels shown in the accompanying table. The CO2 concentration in the year 2000 was greater than it had been at any time in the previous 160,000 years.…

“The global atmospheric concentration of carbon dioxide has increased from a pre-industrial value of about 280 ppm to 379 ppm in 2005. The atmospheric concentration of carbon dioxide in 2005 exceeds by far the natural range over the last 650,000 years (180 to 300 ppm) as determined from ice cores. The annual carbon dioxide concentration growth rate was larger during the last 10 years (1995–2005 average: 1.9 ppm per year), than it has been since the beginning of continuous direct atmospheric measurements (1960–2005 average: 1.4 ppm per year) although there is year-to-year variability in growth rates .”…

Introduction 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.…

There is evidence that global warming is becoming worse primarily due to rise in carbon dioxide concentration in the atmosphere. In 1950s, the concentration of carbon dioxide was at 315 parts per million. Currently, the concentration is about 385 parts per million. To discover an increase in concentration of carbon dioxide throughout history, scientists have used bubbles of air trapped in ice and results show that the current concentration of carbon dioxide is the highest and has been, for more than 10,000 years (Maslin, 2007).…

According to the U.S. Energy Information Administration, in 2000-2013, California was ranked as the second largest producer of CO2 emissions in the United States, behind Texas. Air pollution is an extremely difficult form of pollution to bring into the public eye for two reasons. One, because it is the introduction of microscopic molecules into the atmosphere, it is invisible and often goes unnoticed. Secondly, the effects of these pollutes can take decades of exposure to accumulate and see the true extent of its effects. Over long-term exposure, Carbon emissions speed up the greenhouse effect by trapping more heat in the atmosphere, increasing the risk for prolonged droughts. This process is largely linked to global warming, and is beginning to have devastating effects on California’s already dry and warm climate. CO2 emissions derive from human activities like the burning of gas, coal, oil, and fossil fuels, as well as through intensified land use for agricultural purposes (Castro, Huber…

You probably know that Carbon Dioxide, a greenhouse gas, is the main pollutant that is warming the Earth. Let me tell you that Carbon Dioxide represents 85 percent of all gas emissions caused by human sources. Globally, the largest source of carbon emission is the combustion of fossil fuels like coal, natural gas and oil for energy. On the other hand, electricity production is the biggest generator of carbon emissions; transportation comes in the second place, followed by industry, cars, planes, power plants, and other human activities that involve the burning of fossil fuels, such as gasoline and…
