冰川在环境、社会经济和文化方面的重要性促使一些国家对有关冰川和冰川化环境的活动进行管制。然而，专门保护山区冰川的法律直到最近才被纳入国家政治议程。冰川保护法（GPL）起源于采矿破坏冰川的国家，其目的是保护冰冻圈免受有害活动的影响。在这里，我们分析了阿根廷（已批准）和智利（正在讨论中）的GPL，以确定法律限制和遗漏引起的潜在环境冲突。我们的结论是，全球变暖政策忽视了冰川的动态，可能会阻止或推迟减轻冰川灾害所需的行动（例如人工排水冰川湖），从而使人口面临风险。此外，GPL限制可能会阻碍减轻气候变化不利影响的战略（例如使用冰川湖作为水库）。可以说，需要更灵活的GPL来保护我们免受不断变化的冰冻圈的影响。
The environmental, socioeconomic and cultural significance of glaciers has motivated several countries to regulate activities on glaciers and glacierized surroundings. However, laws written to specifically protect mountain glaciers have only recently been considered within national political agendas. Glacier Protection Laws (GPLs) originate in countries where mining has damaged glaciers and have been adopted with the aim of protecting the cryosphere from harmful activities. Here, we analyze GPLs in Argentina (approved) and Chile (under discussion) to identify potential environmental conflicts arising from law restrictions and omissions. We conclude that GPLs overlook the dynamics of glaciers and could prevent or delay actions needed to mitigate glacial hazards (e.g. artificial drainage of glacial lakes) thus placing populations at risk. Furthermore, GPL restrictions could hinder strategies (e.g. use of glacial lakes as reservoirs) to mitigate adverse impacts of climate change. Arguably, more flexible GPLs are needed to protect us from the changing cryosphere.
