I don't know when the sharks will move in, but this final sentence of the article points to a broader problem with climate change induced migrations: species don't move at the same pace. Plants move much slower than insects, and insects faster then their predators. This will create imbalances, which will lead to big problems with new diseases and pests.

Eventually things will re-calibrate, but a lot of species may go extinct and we could see a very long period of reduced biodiversity. It takes a long time to adapt.
