The Antarctic Peninsula has experienced considerable anthropogenic warming in recent decades. While cryospheric responses are well defined, the responses of moss-dominated terrestrial ecosystems have not been quantified. Analysis of Landsat archives (1986–2021) using a Google Earth Engine cloud-processing workflow suggest widespread greening across the Antarctic Peninsula. The area of likely vegetation cover increased from 0.863 km² in 1986 to 11.947 km² in 2021, with an accelerated rate of change in recent years (2016–2021: 0.424 km² yr⁻¹) relative to the study period (1986–2021: 0.317 km² yr⁻¹). This trend echoes a wider pattern of greening in cold-climate ecosystems in response to recent warming, suggesting future widespread changes in the Antarctic Peninsula’s terrestrial ecosystems and their long-term functioning.

近几十年来，南极半岛经历了相当大的人为变暖。虽然冰冻圈的反应定义明确，但以苔藓为主的陆地生态系统的反应尚未被量化。使用 Google Earth Engine 云处理工作流对 Landsat 档案（1986-2021 年）的分析表明，整个南极半岛普遍存在绿化。可能的植被覆盖面积从 1986 年的 0.863 km² 增加到 2021 年的 11.947 km²，近年来（2016-2021：0.424 km^{2 yr-1}）相对于研究期间（1986-2021：0.317 km^{2 yr-1}）的变化速度加快。这一趋势与寒冷气候生态系统为应对近期变暖而进行的更广泛的绿化模式相呼应，表明南极半岛陆地生态系统及其长期功能的未来将发生广泛变化。
