Science Questions

Q1. How does the structure and organization of the landscape control the storage and flux of carbon and nutrients in a changing climate?

Q2. What will control rates of CO2 and CH4 fluxes across a range of permafrost conditions?

Q3. How will warming and permafrost thaw affect above- and belowground plant functional traits, and what are the consequences for Arctic ecosystem carbon, water, and nutrient fluxes?

Q4. What controls the current distribution of Arctic shrubs, and how will shrub distributions and associated climate feedbacks shift with expected warming in the 21st century?

Q5. Where, when, and why will the Arctic become wetter or drier, and what are the implications for climate forcing?
