Rui Guo and colleagues combined limited historical river flow observations, climate model simulations, and paleohydrologic reconstructions from tree ring proxy data to examine how hydrological ...

Rings are a well-known way to figure out a tree's age. But they also hold clues scientists use to reconstruct the climate of the past, estimating temperatures and precipitation over a tree's lifetime.

The study revealed that blue rings were more common in pine trees than in junipers, appearing in 2.1 percent of the trees' rings compared to 1.3 percent in shrubs. Notably, 1902 and 1877 stood out ...

But for their study, Waddle and her coauthors used tree rings—in the form of tree cores, or centimeter-wide rods extracted from living tree trunks—a little differently. “What we did, which has not ...

An international team of researchers has now examined tree rings of species native to the Peruvian Amazon to determine if trees could be used to show approximately where and when atmospheric ...

Cobb Landmarks is planning to date metro Atlanta's oldest remaining structures by collecting tree ring data in collaboration with the University of West Georgia and other local entities.
