近日，巴拿马运河管理方宣布提高对船舶最大吃水深度的限制，并将运河每日通过的船舶数量降至32艘。在雨季期间，这条占世界贸易量约3.5%的水道平均每天有35至36艘船只通过。但由于旱季延长和蒸发率增加，运河的水位受到影响，当局不得不采取积极措施，应对气候变化对该地区天气和供水可能造成的长期影响。值得注意的是，下调船舶最大吃水深度意味着船舶需要减少载货量，这可能会引发对船舶营运效率和盈利能力的担忧。同时，限制船舶通行数量可能会对依赖运河快速高效通行的全球贸易和供应链带来问题。

The Panama Canal will extend restrictions on ships'maximum depth, and it has limited average crossings to just 32 ships a day. During Panama's rainy season, this canal, which accounts for about 3.5% of this maritime trade, has an average of 35-36 ships typically cross it each day, the authority has said. Due to the extended dry season and higher evaporation rates, the canal’s water levels have been affected. The canal authorities have taken proactive steps, these measures are aimed at preparing for possible long-term effects of climate change on the region’s weather and water supply. If the depth limit were raised, ships would have to carry less cargo to stay afloat, which could impact their efficiency and profitability. This slowdown in traffic can cause problems for global trade and supply chains that rely on the canal’s quick and efficient passage.
