Abstract

Glaciers are often portrayed as an important water resource in scientific research and public debate. However, the scientific literature calls for caution when presenting this idea. While melting glaciers can increase water insecurity, their contribution to runoff is often minor and other factors like excessive groundwater pumping for irrigation or surface and groundwater contamination pose much greater threats to water availability. As we consider the wide range of environmental impacts due to glacier changes, we must also question the “glacier as water resource” narrative that may unnecessarily contribute to public anxiety.

呼吁将冰川准确地描述为水资源
在科学研究和公共辩论中,冰川经常被描绘成一种重要的水资源。然而,科学文献呼吁在提出这一观点时要谨慎。虽然冰川融化会增加水的不安全,但它们对径流的贡献往往很小,而其他因素,如用于灌溉的过量抽取地下水或地表水和地下水污染,对水的可得性构成更大的威胁。当我们考虑到冰川变化对环境的广泛影响时,我们也必须质疑“冰川是水资源”的说法,这可能会不必要地引起公众的焦虑。
