24. Questions GLOBE-Carbon Students will try to Answer Is my school, town or country a source or a sink for carbon? Why? How long is this likely to continue? How many acres of trees are needed to offset my own carbon emissions? What will happen to the ecosystems in my area over the next 100 years? What factors are most likely to cause them to change? Why is C exchange higher in Spain than South Africa? How do C estimates at my school site compare to those measured across the globe? How can I help balance the global carbon budget?
