国际科学家警告，由南极冰盖融化驱动的海平面上升将对中国富裕的沿海城市（包括香港和上海）造成比全球平均水平高15%至20%的冲击。他们表示，南极冰盖缩小导致的引力变化会将海水重新分布向中国人口密集的海岸线。
International scientists warn that sea-level rise driven by melting Antarctic ice will hit China's wealthy coastal cities, including Hong Kong and Shanghai, 15 to 20 percent harder than the global average. They say gravitational shifts from shrinking Antarctic ice redistribute ocean water toward China's densely populated coastlines.
根据国际科学家的最新评估，中国沿海地区的海平面上升速度将显著高于全球平均水平。香港和上海等城市可能经历的海平面上升幅度比全球平均水平高出15%至20%，因为南极冰盖持续融化。
Sea levels along China's coast are set to rise significantly faster than the global average, according to a new assessment by international scientists. Cities such as Hong Kong and Shanghai could see increases 15 to 20 percent higher than the worldwide figure as Antarctic ice continues to melt.
研究人员表示，这种差异源于引力变化：随着南极冰盖质量减少，其对海水的引力减弱，导致海水重新分布，包括向中国人口密集的东部海岸线迁移。这一效应叠加了建在低洼三角洲城市已有的洪水和下沉风险。
Researchers say the disparity stems from gravitational shifts: as the Antarctic ice sheet shrinks, its reduced mass pulls less ocean water toward the pole, redistributing that water elsewhere, including toward China's densely populated eastern coastline. The effect compounds existing flood and subsidence risks in cities built on low-lying deltas.
科学家警告，即使实现《巴黎协定》最雄心勃勃的目标——将全球变暖限制在1.5摄氏度以内——也无法完全抵消中国沿海经济中心面临的加剧风险。研究结果给政策制定者带来压力，要求他们在未来几年加快沿海防御和气候适应规划。
Scientists caution that even meeting the Paris Agreement's most ambitious goal of limiting warming to 1.5 degrees Celsius would not fully offset the elevated risk facing China's coastal economic hubs. The findings add pressure on policymakers to accelerate coastal defences and climate adaptation planning in the years ahead.
