Summary

Story summary

A study published in Science Advances shows king penguins on Possession Island breed 19 days earlier than in 2000, with chick survival rising from 44% to 62%.
Researchers attribute the shift to warmer ocean conditions that increase food availability.
However, warming oceans could push vital feeding zones farther away, complicating hunting for penguin parents.
The researchers warn that, although adaptations are beneficial now, future ocean changes may threaten this progress.
