King penguins on Possession Island are experiencing increased chick survival rates due to climate change, which has led to earlier breeding seasons and an abundance of lanternfish, their primary food source. Research indicates that the penguins began breeding about 19 days earlier in 2023 compared to 2000, resulting in a 62% chick survival rate, a significant increase from 44% in 2000. This is attributed to warmer waters boosting plankton growth, which in turn supports a larger lanternfish population.
