Concordia researchers unveil Quebec’s 19th-century climate history via tree rings

Two studies from Concordia University use centuries-old tree rings to extend Quebec’s climatic record back to the 19th century. By analyzing growth patterns, researchers have detected significant shifts in snowpack and environmental conditions over nearly 200 years. These findings offer crucial insights into historical climate variability and the long-term impacts of environmental change in the region.
