Description
Yang and colleagues track two decades of plant growth in China's Gaoligong Mountains in 2026, asking how extreme weather has helped or hurt the region's greenery. They fused satellite records into a sharp vegetation dataset at 30 meter resolution covering 2000 to 2022, then modeled net primary productivity, the carbon plants lock away after breathing costs. Thirteen extreme climate indices, covering heat, cold, and downpours, were tested against the growth record.
Productivity climbed overall across the 23 years, rising at a trend slope of 1.5 units per year in the team's model, with the sharpest monthly gain in January. The mountains warmed clearly, with six extreme temperature measures rising significantly while extreme rainfall measures barely moved over the study period. Plants answered extremes late, with effects lagging one to two months behind, and hot-day measures like warm-night frequency and daily temperature range explained growth best.
