Here, we present a compilation of five MXD chronologies from Corsican pines that contain high-to-low frequency variability between 1168 and 2016 CE and correlate significantly (p < 0.01) with the instrumental April-July and September-October mean temperatures from 1901 to 1980 CE (r = 0.52-0.64). The growth-climate correlations, however, dropped to0.13 to 0.02 afterward, and scaling the MXD data resulted in a divergence of >1.5 degrees C between the colder reconstructed and warmer measured temperatures in the early-21st century. Our findings suggest a warming-induced shift from initially temperature-controlled to drought-prone MXD formation, and therefore question the suitability of using Corsican pine MXD data for climate reconstruction.
