A Masterclass with Ed Cook, Ewing Research Professor, Lamont-Doherty Earth Observatory of Columbia University, 28 Feb 2013
Precisely dated annual growth rings of trees provide a wealth of information about environmental variability and change that is frequently related to influences of climate on tree growth.
Because of this sensitivity to climate, long tree-ring records have largely rewritten our understanding of past climatic variability and change for large areas of the world over the past millennium.
In so doing, they have provided the critical long-term context for evaluating and comparing 20th-21st century trends in global warming to the past, as well as serving for tests of the causes of past and present temperature changes.
This masterclass reviewed the principles and practices of tree-ring research, known more formally as dendrochronology, with an emphasis on crossdating, series replication, and the statistical processing of these records into a form suitable for studies of past climatic and environmental change.
Professor Ed Cook is a 2013 Gledden Visiting Senior Fellow at The University of Western Australia.
