a Aerial view of the whole-soil-profile warming experiment conducted at the Haibei Alpine Grassland Ecosystem Research Station on the Qinghai-Tibetan Plateau, China. The experiment involved two climate treatments, namely warming vs. ambient temperature, arranged into eight plots, with four replicates for each treatment. Each plot was equipped with a PhenoCamera. b A three-dimensional layout diagram depicting the arrangement of 20 heating rods, each 100 cm deep, around a plot with a diameter of 3.5 m, along with two circular heating cables situated 5 cm below the soil surface at radii of 0.5 and 1 m from the plot center. This method resulted in an average warming effect of ~2.2 °C for the surface soil (5 cm) and 4.0 °C for deeper layers of the soil profile (10–100 cm). Temperature and moisture sensors were used to monitor soil temperature and water content, respectively (Supplementary Fig. 1).
