Globalne zmiany klimatu sprawiają, że coraz częściej pojawiają się ekstremalne zjawiska atmosferyczne - i są one coraz gwałtowniejsze. W rejonie Morza Bałtyckiego zaczynają się pojawiać silne wichury, podobne do huraganów i tornad występujących na Atlantyku. Jak zjawiska te wpływają na linię brzegową?

Due to the ever-changing global climate, the frequency and intensity of extreme atmospheric phenomena are increasing. Strong winds, similar to hurricanes and tornados observed on the Atlantic, are starting to appear in the region of the Baltic Sea. How are they affecting Poland's coast?
