Other properties of the annual rings, such as maximum latewood density (MXD) have been shown to be better proxies than simple ring width. Dendroclimatology is the science of determining past climates from trees primarily from the properties of the annual tree rings. ONE AUGUST AFTERNOON IN 2010, Michael Mann was opening mail in his office at Penn State University when a dusting of white powder emerged from an envelope. Every year, a tree forms a new ring subdiscipline plays in broader research on climate change. But trees can keep a much longer record of Earth's climate. Dendrochronology, the scientific method of studying tree rings, can pinpoint the age of archaeological sites using information stored inside old wood.

Each tree tells the story of its life! The "DRL team" are particularly focused on the reconstruction of extreme climate events such as drought and flooding. Andrew Ellicott Douglass from the University of Arizona first used this specialized branch of science in the early 1900s. In order to conduct blue intensity measurements, the tree ring core is first scanned using a flatbed scanner. Initial Results The Initiative produced the most comprehensive tree-ring record ever collected for coast redwoods and giant sequoias, allowing us to see how climate events such as droughts, fire and flooding have affected redwoods' growth across history. The color and width of tree rings can provide snapshots of past climate conditions. "Dendrochronology, for a century, has been looking at the relationship between the width of these rings and the climate conditions that the rings were formed under," Evans said. Subscribe. "This is a central question in ecology, and it has become even more important with climate change," said study co-author Margaret Evans, assistant professor of dendrochronology in the UArizona . Generally, dendroclimatologists use large databases of tree ring data to compare the records of many trees, and interpret when, where, and how quickly climates have changed. Michael Mann Fought Climate Denial. t Once the rings' variations are deciphered, they can help determine climate for times when there are no records. Dendrochronology is a relatively young and dynamic branch of science based on the extensive record of the past environment and climate that is evident in the biological growth of trees. Working in collaboration with Chris Guiterman (University of Arizona), Navajo Forestry, and the BIA, we are using tree rings to identify and assess the vulnerabilities of Navajo forests to climate change. One way scientists are learning about past climate is by studying tree rings. Dendrochronology is a scientific method that uses the annual growth rings on trees to find out the exact year the tree was formed, which helps scientists date events, environmental change, and archaeological artifacts.
