Q4.23. Some researchers have hypothesized that the feedback loop pictured below influences the carbon dynamics of Arctic ecosystems as follows: Elevated atmospheric CO2 levels cause the climate to warm, thawing permafrost. Nitrogen mineralization is then stimulated as thawed permafrost decomposes. The resulting increase in soil ammonium then stimulates primary production, which pulls CO2 from the air. What kind of feedback loop is described? Temperature-Mineralization Feedback Co, Level us Primary Production Temperature N- Mineralization A positive feedback loop that amplifies the...

4. In studying climate, scientists are often concerned about positive feedback loops: two or more pro- cesses that amplify each other, creating a system of amplification that leads to a vicious cycle. One example is the interaction of water vapor with global temperature. If global temperature increases, the capacity of the atmosphere to contain evaporated water vapor also increases. If water resources are available, this would result in an increased amount of water vapor in the atmosphere. Water vapor is...
