Hypothesis In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.

Procedure 1. Complete your hypothesis (above). 2. Identify the independent (test) variable and the dependent (outcome) variable: __________________________ 3. Practice using the computer model. Select each marker to see what it does. Here is a summary you can refer back to as you complete your experiment. · Carbon Dioxide Emissions Slider: You will use the arrows to change the amounts of carbon emissions. · Time Step Size: This will allow you to view the data every 5 years or every 10 years. · Start Over: Use this to reset the model if needed. 4. The current carbon emissions are 9.8 gigatons, or 9.8 billion tons. Complete all three scenarios to find out what happens to the global temperature if these emissions stay the same, decrease, or increase over the next century. Follow the instructions in the Data section of this report.

Data For each scenario, record the carbon dioxide emission rate and the global temperature. The data for the years 1960–2010 are already filled out for you. Scenario One: Carbon dioxide emissions stay the same · Set the carbon dioxide emissions rate to 9.8 gigatons. · Set the time step size to 10 years. · Select step forward until you have the data through the year 2110. · Record the data in the table below. Year Carbon Emissions (gigatons) Temperature (Fahrenheit) ........ Maintain carbon dioxide emissions at 9.8 for the rest of scenario one. Scenario Two: Carbon dioxide emissions decrease · Set the carbon dioxide emissions rate to 9.8 gigatons. · Set the time step size to 10 years. · Select the step forward button once. · Decrease the carbon dioxide emissions by 0.2 and press step forward. · Continue stepping forward once, decreasing the carbon emissions each time, until you reach 2110. · Record the data in the table below.

The understanding of Earth's atmosphere and the impact of human activities on climate dynamics is crucial for addressing ongoing environmental challenges. This report explores the effects of carbon dioxide (CO2) emissions on global temperatures through a simulated experiment, examining three scenarios: constant, decreasing, and increasing emissions over a century. The purpose of the experiment was to model how different emission trajectories influence atmospheric temperatures, aiding in understanding the broader implications of greenhouse gases on climate change.

The hypothesis posited that maintaining current CO2 emission levels would lead to an increase in global temperature, decreasing emissions would stabilize or reduce the temperature rise, and increasing emissions would accelerate warming. The independent variable in this experiment was the CO2 emission rate, while the dependent variable was the global temperature. These variables were manipulated using a computer-based climate model, which allowed for scenario testing over simulated timelines spanning from 1960 to 2110.

In the first scenario, where emissions remained constant at 9.8 gigatons, the data indicated a steady increase in global temperature, consistent with the greenhouse effect. The temperature rose incrementally as greenhouse gases trapped more infrared radiation, leading to warming. This supports the understanding that elevated CO2 levels correlate with higher global temperatures. In the second scenario, where emissions decreased by 0.2 gigatons every decade, the temperature increase was less pronounced over time. The decline in CO2 emissions limited the greenhouse effect, which resulted in a stabilization or slight decrease in temperature towards the latter part of the century. Conversely, in the third scenario, with increasing emissions by 0.2 gigatons each decade, the temperature trend showed a sharp and continuous rise. This scenario exemplifies the potential acceleration of global warming if emissions are not curbed.

Results confirmed that the hypothesis was supported: higher emissions correlate with higher temperatures, while reductions tend to stabilize or lower global temperature increases. The greenhouse effect refers to the process whereby greenhouse gases such as CO2, methane, and water vapor trap solar radiation in Earth's atmosphere, preventing it from escaping into space and thus warming the planet. Global warming, however, describes the long-term rise in Earth's average temperature due to increased greenhouse gases.

The level of CO2 directly affects the global temperature because CO2 molecules absorb infrared radiation emitted from Earth's surface, re-radiating it back downward, which enhances the greenhouse effect. This process amplifies atmospheric warming, leading to climatic shifts. Major sources of atmospheric CO2 include fossil fuel combustion (coal, oil, natural gas), deforestation, and industrial processes such as cement production. Reducing emissions from these sources is essential to mitigate the pace of climate change and minimize adverse environmental impacts.
