Solar Radiation Management (SRM) is a climate intervention strategy aimed at mitigating global warming by reducing incoming solar radiation. We investigate the potential influence of SRM on Andean glacier-wide surface mass balance, as glaciers are crucial for downstream ecological functions along the west coast of South America. We numerically simulate the surface mass balance response of thousands of glaciers to SRM and other climate change scenarios throughout the 21^st century. Results indicate Pan-Andean negative mass balance, irrespective of the scenario or glacier-climate regimes. However, SRM tends to modify interannual variability and temperature sensitivity in several regions. Our findings also suggest that if SRM had been implemented in the late 1980’s, it would have been effective in avoiding the negative trajectory seen today. The Andes feature nearly all mountain hydroclimatic regimes, representing a globally relevant example of SRM impacts. These findings emphasize the urgency of drastic emissions reduction.

太阳辐射管理 （SRM） 是一种气候干预策略，旨在通过减少入射的太阳辐射来缓解全球变暖。我们研究了 SRM 对安第斯冰川范围表面质量平衡的潜在影响，因为冰川对南美洲西海岸的下游生态功能至关重要。我们以数值模拟了整个 21^世纪数千座冰川对 SRM 和其他气候变化情景的表面质量平衡响应。结果表明，无论情景或冰川气候状况如何，泛安第斯山脉都存在负质量平衡。然而，SRM 往往会改变几个地区的年际变率和温度敏感性。我们的研究结果还表明，如果在 1980 年代后期实施 SRM，它将有效地避免今天看到的负面轨迹。安第斯山脉几乎具有所有山地水文气候状况，代表了 SRM 影响的全球相关示例。这些发现强调了大幅减排的紧迫性。
