Keith Briffa

Keith Raphael Briffa was a climatologist and deputy director of the Climatic Research Unit. He authored or co-authored over 130 scholarly articles, chapters and books. In his professional work, he focused on climate variability in the late Holocene, with a special focus on northern portions of Europe and Asia. Briffa's preferred method was dendroclimatology, which is a set of procedures intended to decode information about the past climate from tree rings. Briffa helped develop data sets from trees from Canada, Fennoscandia, and northern Siberia which have been used in climate research.
