Research Highlight:Northeastern North America as a potential refugium for boreal forests in a warming climate

Novus participant Neil Pederson (Harvard) and colleagues recently published a new study in Science on the potential for future boreal forest climate refugia in North America. The study compiled growth records from 16,450 tree-ring records spanning 583,000 square kilometers of boreal forest in Québec, Canada. The authors found that below 49°N, growth decreased under future temperature and precipitation; however, above 49°N, increases in temperature resulted in increased growth even under drier conditions. Consequently, the authors concluded that northeastern North America may serve as boreal forest refugia under future climate scenarios.
