Question 1. How does the distance between South America and Africa compare between the PETM and today? Why do you think that is?
Question 2. Why is the PETM of interest to climate scientists? Need Assignment Help?
Question 3. What was the largest temperature increase during the PETM (give your answer in degrees Celsius)?
Question 4. Which oceanic site (i.e. only site with numbers located in the ocean basins) had the smallest temperature change during the PETM? Which oceanic site had the largest change during the PETM?
Question 5. Based on this data, do you see any patterns in temperature increases with regard to latitude (i.e. do you think there is a difference in the magnitude of warming between the equator and the poles?)? Or do you think there is no discernable pattern with regard to latitude?
Question 6. Compared to modern temperatures, are the ocean sites warmer or colder during the PETM?
Question 7. Which oceanic site (i.e. only sites with numbers located in the ocean basins) has the smallest temperature difference between PETM and modern?
Now turn off the Modern temperature map and turn on the Projected 2100 map and answer the following questions.
Question 8. Comparing this to the PETM where there is no general pattern of warming with latitude, does the 2100 projection have a latitudinal pattern? Yes or No
Question 9. Which latitudes are predicted to have the most significant warming? Why do you think this is?
Question 10. The modern-day rate of carbon emissions was estimated to be 9.795 billion tonnes for 2014 due to fossil fuel use. One study (Cui et. al. 2011) found that the peak rate of carbon emissions during the PETM was 0.3 - 1.7 billion tonnes per year. Considering your answer to #2, what conclusions could you draw about the future (2100 and beyond)?
