|How might this change marine life populations? What impact could fifty years at this level of emissions have on marine fauna? On marine |
|flora? The more total carbon concentration (smokestack) that people pumped into the atmosphere by burning fossil fuels, the more the |
|oceans would absorb. The ocean would continue to soak up carbon until global warming heated the ocean enough to slow down ocean |
|circulation. Water trapped at the surface would become saturated, at which point, the ocean would slow its carbon uptake. Marine life |
|populations could be affected by the food supply and the temperature. In fifty years at this level of emissions the level of both marine|
|fauna and flora will be severely damaged by high levels. |
|In addition to circulating through the carbon cycle, where else might excess carbon be found? In fifty years, where would you be most |
|likely to see excess carbon? Excess carbon could be found everywhere. In fifty years you may be more likely to see excess carbon in the |
|deep ocean from an excess of carbon in the atmosphere. |
|Which areas are most highly (and quickly) affected by an increase in carbon emissions (and increase in fossil fuel consumption)? How |
|would these
