4. HW#2 Please answer the following question using open book research and your own words, max 2 pages (you must provide references): Global conditions are: Increased CO 2 in the atmosphere, the ocean surface temperature increased by 1°C, and pH dropped by 0.2; Describe possible scenarios regarding changes in the ocean carbon pump and effects on the marine life! (Use the carbonate buffering system to describe possible changes and effects on ocean chemistry and biology. Explain if the carbon pump will increase or decrease; and if the pH will stabilize or continue to drop?)
