Global marine life is on the move due to sea temperature rises

In the ocean, tropical species are moving from the equator towards the poles as sea temperatures rise. Meanwhile, temperate species are receding as it gets too warm, they face increased competition for habitat, and new predators arrive on the scene, among other factors.

This mass movement of marine life, termed tropicalization, is changing the ecological landscape of our oceans and leading to a cascade of consequences for ecosystems, biodiversity, and potentially the global economy.
