image: Fraction of the ocean surface annually experiencing extreme heat, grouped by a, Northern Hemisphere and b, Southern Hemisphere and Indian ocean basins. The Point of No Return (PoNR) occurs when each series surpasses and remains above 50% (dashed grey line), or when the historical baseline of extreme heat becomes ‘normal’. This first occurs in 1998 in the South Atlantic basin and for the global ocean occurs in 2014. view more
