In tree rings, Concordia researchers examine Quebec’s 19th century climate

Quebec tree rings dating back nearly 200 years indicate snowpack in the Gaspésie mountains has declined considerably in recent decades, Concordia University researchers suggest in a study that could give further insight into dwindling caribou herds and hydro energy forecasts.The tree ring study goes back to 1822, extending by more than 100 years the records otherwise kept by local weather stations and river gauges. It underlines how climate change has already reshaped the region, the study said.
