Diverse responses of radial growth to climate across the southern part of the Asian boreal forests in northeast China

•Diverse growth-climate responses driven by local climate exist across the study area.•Limitations to radial growth varied in relation to the latitudinal climate gradient.•Warming negatively affects tree growth in the southern part of Asian boreal forests.•The percentage of trees threatened by warming will increase by 46%–64% by 2100.•Regionally-specific measures are urgent to take for sustaining forest productivity.
