Ocean temperatures are at record highs in many parts of the world and Antarctic sea ice has reached its lowest level ever for winter, when it should be at its maximum extent. Meanwhile a new study warns that hugely important ocean currents in the Atlantic Ocean could collapse in the next couple of years and UN Secretary-General Antonio Gutteres says we've entered the era of "global boiling".

To make sense of these oceanic climate extremes, we speak to oceanographer Edward Doddridge from the Institute for Marine and Antarctic Studies at the University of Tasmania.
