Short summary
This study explores how rising CO₂ and increasing temperatures affect the growth of Himalayan fir trees on the Tibetan Plateau, particularly in relation to water availability. We found that, while tree growth in wet, high-elevation areas improved with increased CO₂, growth in dry, low-elevation areas declined due to water stress. These findings suggest that, while CO₂ may boost growth in some areas, the negative effects of drought may outweigh these benefits.
