Climate-sensitive periods of tree growth are advancing in cold and delaying in dry climates
Global warming alters the strength of tree-growth responses to climatic variability, but changes in the timing and duration of critical climate-sensitive periods (CSPs) remain uncertain. We quantified CSP dynamics using an extensive extratropical tree-ring network (2,907 sites across six Köppen–Geiger climate zones) together with daily climate data for 1950–2010. In cold-limited regions, CSPs shifted earlier, with both earlier onset (-4.6 ± 0.3 days decade⁻¹) and earlier end (-3.8 ± 0.3 days decade⁻¹), consistent with spring and early-summer warming and associated phenological advances. In contrast, water-limited sites showed a later CSP end (0.5 ± 0.2 days decade⁻¹) and an overall lengthening of the CSP (1.3 ± 0.1 days decade⁻¹), likely because intensifying drought increases water stress and delays peak climate sensitivity. These shifts in the magnitude and timing of tree climate sensitivity are likely to continue under ongoing warming, with direct implications for forest carbon dynamics and their projection.
