Marine species increasingly can’t live at equator due to global heating

Study suggests it is already too warm in tropics for some species to survive

Global heating has made the ocean around the equator less rich in wildlife, with conditions likely already too hot for some species to survive, according to a new study.

Analysis of the changing locations of almost 50,000 marine species between 1955 and 2015 found a predicted impact of global heating - species moving away from the equator - can now be observed at a global scale.
