Britt Stephens examines how the Earth's biogeochemical systems, such as forests and ocean regions, respond to natural and human-induced perturbations. He is an expert at building new instruments and adapting new technologies to study the global carbon cycle and has worked on research expeditions in forests, at sea, and aboard aircraft. His goals include improving predictions of and strategies for mitigating future climate change. Stephens is a researcher in NCAR's Earth Observing Laboratory.
