Fig. 4 — FVC trends estimated by the stepwise multiple linear regression (SMLR) model from 2015 to 2050 under different shared socioeconomic pathway (SSP) and representative concentration pathway (RCP) scenarios (i.e., SSP1-2.6 a, SSP2-4.5 b, and SSP5-8.5 c) from the Coupled Model Intercomparison Project Phase 6 (CMIP6) model experiments and their corresponding trend lines d. The stippling in a–c marks regions with significant trends (passed the Mann-Kendall test at the 95% significance level). The line referred to as Obs-predict in d was estimated based on the SMLR model and historical environmental factors. All scenario simulations were modified by removing the errors between the simulated and observed data during the reference period of 1982–2014 (Supplementary Note 4), and the differences among the three scenarios are shown in d since 2014.
