Science Nation - Lord of the Tree Rings

submitted by: nsf
David Stahle travels to ancient forests around the world, collecting tree rings to learn more about major climate and historical events dating back hundreds and thousands of years. With help from the National Science Foundation, he uses Dendrochronology, or tree-ring dating, to get a snapshot of climate change over time. Stahle can also determine things like the socioeconomic impact of droughts. In fact, in 1998, he made the front page of the New York Times with his discovery that drought...

Collaborative studies on tropical Asian dendrochronology: Addressing challenges in climatology and forest ecology

submitted by: UP Los Baños
A report on the Asia Pacific Network Global Change Research-funded project aimed to (1) establish tree ring laboratories in the region, (2) conduct reconnaissance of indigenous tropical Asian tree species with clear distinct growth rings, (3) conduct preliminary work to find if tree species with distinct growth rings have relevance to reconstructing past events, and (4) to establish and maintain a xylaria.
