Short summary
Tree rings are long-term recorders of past climate variations, but the origin of the climate signals imprinted is difficult to interpret. Here, using a complex model we show that the temperature signal recorded in tree rings from two species from North and South America is likely related to processes occurring at the leaf level. This result contributes to the quantitative interpretation of these proxies for their future exploitation for millennium-scale climate reconstructions.
