Penguin Sentinels
We travel with conservation biologist Dee Boersma to the Galapagos Islands where she works to support a population of penguins that are being impacted by climate change in this video from QUEST. Boersma has been studying these penguins for over 30 years.
Her studies have revealed that the biggest threat to the survival of these temperate penguins is climate change. Global climate change has increased the frequency of weather patterns called El Niño events. El Niño events produce stronger and more frequent storms, and they reduce upwelling; which occurs when cold oxygen and nutrient rich waters are brought up from the deep ocean.
