B54C:
Integrated Understanding of Climate, Carbon, Nutrient Cycles, Human Activities, and Their Interactions in Terrestrial Ecosystems III

Submit an Abstract to this Session



Session ID#: 31725

Session Description:
Assessments of coupled climate–carbon cycle simulations indicate that terrestrial carbon cycle feedbacks are highly uncertain and could significantly alter the rate of atmospheric CO2 increase and, therefore, climate change over the next one hundred years. The terrestrial carbon cycle is directly affected by increasing atmospheric CO2 levels and by climate change, and, further, is altered indirectly by feedbacks from potentially limiting nutrients (e.g., nitrogen and phosphorus). Changes in CO2 concentration and climate can affect the availability of these nutrients, and anthropogenic disturbances—such as tropospheric ozone, nitrogen deposition, and land cover and land use changes—also influence the carbon cycle, nutrient cycles, climate change, and the strength of their interactions. This session will focus on an integrated understanding of carbon, nutrient cycles, climate change, human activities, and their interactions and feedbacks to climate in terrestrial ecosystems.
