If only half of the flora (plants) in the world existed in 2110 (perhaps due to deforestation), what do you predict the atmospheric carbon level would be? 2. What is the relationship between increased carbon in the ocean and increased carbon in the soil? How else might carbon be transferred to soil? 3. Step 2: What is the general trend between fossil fuel consumption (oil, gas, and coal combined) and atmospheric carbon?

Set the fossil fuel consumption to “None.” Without any fossil fuel consumption, which parts of the cycle have improved their carbon levels in comparison to previous data? 2. Which sections of the cycle have improved from the previous levels you have recorded but still are increasing their carbon levels? 3. What effect does a high carbon level have on the deep ocean? Why might it be important to keep an eye on the deep ocean carbon levels? What could that one number tell you about the cycle as a whole? 4. Step 2: Try reducing the level of fossil fuel percentage increase and decrease deforestation to 0 GT per year. Predict what will happen to the atmospheric carbon levels and record it in your Data Table. Run the simulation to test your hypothesis. Were you correct? Were you surprised by the result? What about your result surprised you? DATA TABLES: CARBON CYCLE LESSON 3 (5 points) Lesson 3: Step 1 To Year 2010 2070 2090 2110 Atmospheric Carbon (GT) Net Def.

By 2110, how has the terrestrial flora (plant) carbon changed over the 100-year span? 2. What is the increase in carbon level in the soil over the 100-year span? 3. Compare this chart to the first one you made. By 2110, how are soil carbon levels different? Is this a big change? Compare this to the change in atmospheric carbon levels. 4. Assume that, in this hypothetical scenario, the tundra melting is inevitable and there is a 2% increase in fossil fuel consumption. Which of the two rates of melting would have a greater impact on coastal seaweed populations in 2110? ...
