Increased drought frequency causes the extra-compensation of climate wetness on tree growth to fade across inner Asia

•Temporal changes of wetness compensation effects on tree growth were investigated.•Compensation effects in Inner Asia was 2.5 times higher than the global average.•Spatio-temporal patterns of growth response to climate extremes became divergent.•Extra-compensation of tree growth by climate wetness was fading since 1980s.•Uncompensated decline in tree growth is important for the future carbon dynamics.
