据初步预测,1990年的风暴潮和海浪灾害发生的次数均较海洋灾害较为严重的1989年偏少。这是上海海洋环境预报区台近日发布的海洋灾害预报。虽然1990年的天文潮年极值比去年偏低20厘米,但自二十世纪三十年代以来,由于二氧化碳“温室效应”,导致两极冰盖范围缩小,全球海平面缓慢上升;同时随着地下水及其它资源的不断开采,地面在缓慢 According to preliminary forecasts, the number of storm surges and wave disasters in 1990 were both slightly lower than those in 1989, the more serious the marine disasters were. This is a forecast of marine disasters recently released by Shanghai Marine Environment Forecasting Station.

Meanwhile, as the groundwater And other resources continue to mining, the ground is slow
