The Dictionary of the Climate Debate (DCD)


Briffa, Keith






(1952) A scientist at the University of East Anglia's CRU, he's one of the world's very few celebrity dendro-climatologists. Skeptic bloggers have accused him (see YAD06) of fiddling with tree-ring data to try to suppress the Medieval Warm Period.

Briffa on the MWP

"For the record, I do believe that the proxy data do show unusually warm conditions in recent decades. I am not sure that this unusual warming is so clear in the summer responsive data. I believe that the recent warmth was probably matched about 1000 years ago. I do not believe that global mean annual temperatures have simply cooled progressively over thousands of years as Mike appears to and I contend that that there is strong evidence for major changes in climate over the Holocene (not Milankovich) that require explanation and that could represent part of the current or future background variability of our climate."
