<p dir="ltr">Warming can alter the temporal stability of aboveground net primary productivity in grasslands. However, it remains unclear how ANPP stability responds to long-term warming. Through a 10-year in-situ manipulative warming experiment conducted in an alpine meadow on the Qinghai-Tibetan Plateau, we found warming initially enhanced ANPP stability and the positive effects of warming on ANPP stability tended to decline as the duration of the experiment was extended.</p>
