Question

8.0 1 In 2016, atmospheric CO2 was at ppm, and oceanic pH was at 8.1 400 600 700 800 positively (or directly) negatively (or inversely) 2 Under the Optimistic scenario, CO2 concentrations in the atmosphere will increase but will remain under ppm through 2090 3. Under the Middle Ground scenario. CO2 concentrations in the atmosphere will get close to, but are not projected to exceed 4. Under the Pessimistic scenario. CO2 concentrations in the atmosphere are projected to exceed ppm by 2090 ppm by 2090 5. Across all three scenarios, ocean pH falls below by 2090 6 From the information in the graphs, you can conclude that oceanic pH and atmosph enc CO2 concentration are correlated 7. Although not reflected in this graph. you can infer that as atmospheric carbon dioxide increases, oceanic carbon dioxide concentrations also increase, suggesting that the two variables are correlated

Explanation / Answer

In 2016, atmospheric co2 was 400ppm and oceanic pH was 8.1. Under Optimistic snenario ... 600ppm by 2090. Under middle... 700ppm by 2090. Under pessimistic.... 800ppm by 2090. Across...pH falls below 8.0 by 2090. From the information in the graphs you can conclude that oceanic pH and atmospheric CO2 are negatively (inversely ) related. Although..... atmospheric and oceanic CO2 are positively (directly ) related.
