The Antarctic Peninsula and the adjacent South Shetland Islands show a significant atmospheric warming trend. Increase in air temperature is commonly associated with glacier melting. However, there is a dearth of documentation about the glaciers of Greenwich Island. This study fills a knowledge gap about glacier melting on Greenwich Island by focusing on four glaciers located on the northern part of it. We also update the temperature trends and analyze the relationship between glaciers melting and temperature changes. We used airborne, optical and SAR satellite sensors along with in-situ measurements over the 1956–2019 period to map glaciers extent changes. The total ice cover of these glaciers decreased from 10.01 km² in 1956 to 7.97 km² in 2019, i.e. 20.4%. The results suggest a glacier loss rate of 32359 m²/year (−0.32%/year). This rate of loss is coherent with other measurements made in the South Shetland Islands. We also update the air temperature rising trend in this area to +0.23 °C/decade between 1966 and 2018 at Chile's Arturo Prat base. We do however find two significant trends over the last sixty years: +0.36 °C per decade between 1966 and 1998 and a sharp decrease between 1998 and 2015 of −0.6 °C per decade.

南极半岛和邻近的南设得兰群岛显示出明显的大气变暖趋势。气温升高通常与冰川融化有关。但是，关于格林威治岛冰川的文献很少。这项研究通过集中研究位于格林威治岛北部的四个冰川，填补了有关冰川融化的知识空白。我们还将更新温度趋势，并分析冰川融化与温度变化之间的关系。我们使用了机载，光学和SAR卫星传感器以及1956–2019年期间的原位测量来绘制冰川范围变化的地图。这些冰川的总冰盖从1956年的10.01 km ²减少到7.97 km ²在2019年，即20.4％。结果表明，冰川损失率为32359 m ² /年（-0.32％/年）。该损失率与南设得兰群岛的其他测量结果一致。我们还将1966年至2018年之间智利Arturo Prat基地的该区域气温上升趋势更新为+0.23°C /十年。但是，我们确实在过去六十年中发现了两个重要趋势：1966年至1998年期间，每十年+0.36°C，1998年至2015年期间，每十年−0.6°C急剧下降。
