CNN —It’s not just ocean heat that’s affecting marine life – new research shows extremely cold events are welling up and causing mass mortalities. And the same planet-warming pollution that’s driving the climate crisis is likely to blame for these “killer events” on the other end of the temperature spectrum. The world’s oceans have been plagued by unprecedented heat over the past year, fueling concerns for marine life. “Climate change is actually really complex,” said Nicolas Lubitz, lead author of the study and a researcher at James Cook University in Queensland, Australia. He said seasonal upwelling events are common in that area, with water temperature dropping quickly.
