Researchers look to carbon isotopes and cell-level wood anatomy to understand how seismic-induced changes in water availability affect tree growth.
Trees tell of a wetter past along the Brahmaputra River and, combined with climate modeling, suggest heightened future flood risks in one of the world’s most densely populated areas.
Mass spectroscopy of tree ring material indicates a sharp, single-year rise in carbon-14 concentrations consistent with an extreme solar energetic particle event that occurred around 5410 BCE.
A method using nonpooled, continuous stable carbon and oxygen isotopes recorded in oak trees benefits climate reconstructions.
Climate change–induced drought may have had an influence on the Civil War.
The trade-off between tree longevity and life expectancy can mean future carbon uptakes are overestimated in current global climate models.
By analyzing thousands of oak timbers dating from the 4th to 21st centuries, scientists have pinpointed the advent of a forest management practice.
Tree rings reveal how severe cold and political isolation brought disaster to Scotland, inspired a colonization effort in Panama, and helped drive union with England.
An analysis of timber used to construct buildings in Europe hundreds of years ago is giving scientists and historians new insights into the region’s history from the 13th to 17th centuries.
