When the Oceans Come for Your Tap

The oceans are changing, but they are not changing alone. Many evident impacts ofchanging sea level occur on the surface, and we oftentimes miss the silent companion beneath the surface. Saltwater intrusion, the underground salinization of coastal fresh groundwater, is already and will be widely rampant across global coastlines. Recent analysis shows that by 2100, more than 75% of the world’s coastal regions will experience some form of saltwater intrusion, driven by changing rain patterns on land or sea level.

海洋正发生变化，但其变化并非孤立存在。海平面变化的诸多显著影响均显现于地表，而我们往往忽视了地表之下的隐秘伴随现象。海水入侵（Saltwater intrusion）——即沿海淡水地下水发生的地下盐渍化——目前已在全球沿海地区广泛蔓延，未来这一态势亦将持续加剧。近期分析研究显示，到2100年，全球超过75%的沿海区域都将遭遇不同程度的海水入侵，其驱动因素包括陆地降雨模式改变与海平面变化。
