Climate change threatening the 'conveyor belt of the ocean'

Scientists from across the globe are converging in New Orleans this week for the world's largest ocean sciences conference. It's the first time the event has taken place in-person in four years, due to the pandemic. A key focus this year- how climate change is impacting ocean circulation. It coincides with new study that has found the Atlantic circulation - which helps regulate the global climate system- is at risk of total collapse.
