Hate to tell ya but seen much more from north sawyer glacier in Tracy arm just south of Juneau and Aialik glacier outside of Seward on boats I worked on.😉
No, ice falling into the sea is just like the rain falling. I suppose that, every time it rains, you complain that Planet Earth is running out of water. Every time you see a river, you burst into tears, wailing, "We are losing our water! Boo-hoo-hoo!!!"
