In 1990, the Paleoclimatology Program of the National Oceanic and Atmospheric Administration (NOAA) took over the operation of the ITRDB with the establishment of the World Data Center - A for Paleoclimatology at the National Geophysical Data Center (NGDC) in Boulder, Colorado, USA.

Dendrochronology and its related subfields (e.g., dendroecology and dendroclimatology) have proven invaluable disciplines for investigating spatial and temporal aspects of processes in the earth sciences that operate at annual to centennial time scales.

These efforts allow researchers to (1) develop and test new hypotheses that investigate the effects changes in regional and global-scale atmospheric circulation processes could have on human behavior, pattern, adaptation, and response, and (2) place current changes in global climate processes, often attributed to anthropogenic influences, in context with previous changes in past climate.

The rapid development of large numbers of tree-ring chronologies across the globe was addressed by dendrochronologists attending a workshop in 1974, who subsequently established the International Tree-Ring Data Bank (ITRDB), a professional organization that provides the only central repository for all types of dendrochronological data from around the world.

For years, the ITRDB operated exclusively as a "grass roots" organization, largely dependent on the time and efforts of volunteers.

Modest funding was supplied by the United States National Science Foundation as a supplement to research support for Dr. Fritts, the founder of the ITRDB, at the Laboratory of Tree-Ring Research, The University of Arizona.

Dendrochronology is currently practiced worldwide in laboratories at academic, government-funded, and private institutions by nearly one thousand practitioners, which has resulted in the development of thousands of tree-ring chronologies from sites around the world.

These data sets are increasingly being used to assess past changes in Holocene climate to place the global dynamics of present and future climate change in historical context.

Recent, intensive efforts have focused on the development of millennium-length tree-ring chronologies to investigate not only short-term, intradecadal (100 years) secular trends.

Spatial networks or grids of tree-ring chronologies have been or are currently being developed to provide information about past climate on regional and global spatial scales.
