The interaction between natural and human systems is a two-way street; the impacts are jointly determined by what happens in both systems and the feedback loops that lead to adaptations and change. Understanding better how humans and environmental systems co-evolve–the likely direction and trends–is vital for allocating scarce resources to protect the earth.

To date many global change questions have focused on a component (e.g. the C cycle or sea level rise). The true outcomes of global change will be dictated by cumulative impacts, interactions and feedbacks. If they’re not addressed we may get some nasty non-linear surprises.
