Dendrochronologist Brendan Buckley’s usual occupation is drilling straw-like cores from old trees and extracting information about past climates by studying their rings. To extend the record beyond the time of living trees, he sometimes takes samples from long-dead trees, or even from timbers in ancient buildings. In 2010, the Lamont-Doherty Earth Observatory scientist was part of a team that traveled into the remote Cardamom Mountains of southern Cambodia to investigate human burials contained in coffins carved from entire logs.
Tree-Ring Lab (TRL) scientists are dedicated to expanding the use and application of tree-ring research around the world to improve our understanding of past climate and environmental history. Current research concentrates on the use of tree-ring data networks to study regional climate, global climate teleconnections and anthropogenic impacts on forest growth.
Exploring new species in new regions, building collaborations around the world, and developing new quantitative techniques, TRL researchers are committed to advancing dendrochronology and paleoclimatology, as well as the ethic of good science

“I was deeply saddened by the loss of one of our most beautiful trees on campus during the last storm. It had perfect symmetry and such a beautiful color display late in the fall,” wrote geochemist Martin Stute, after a highly unusual heavy October snow felled a 22-year-old Bradford pear at Lamont-Doherty Earth Observatory, where he works. The tree had stood since 1989 in front of the Seismology/Marine Biology building–for many, a shady regular lunch spot, and stately natural contrast to the squat, corrugated-metal architecture of the human structure behind it. Stute emailed Lamont colleagues his brief eulogy, with an attached picture of the tree in happier days. Dozens replied.

Scientists have long known that large volcanic explosions can affect the weather by spewing particles that block solar energy and cool the air. Some suspect that extended “volcanic winters” from gigantic blowups helped kill off dinosaurs and Neanderthals...

The seasonal monsoon rains in Asia feed nearly half the world’s population, and when the rains fail to come, people can go hungry, or worse. A new study of tree rings provides the most detailed record yet of at least four epic droughts that have shaken Asia over the last thousand years..

Decades of drought, interspersed with intense monsoon rains, may have helped bring about the fall of Cambodia’s ancient Khmer civilization at Angkor nearly 600 years ago, according to an analysis of tree rings, archeological remains and other evidence.
