- A study revealed that blue whale vocalizations have decreased by approximately 40 percent over six years, raising concerns among scientists.
- This reduction in singing is attributed to the disappearance of their main food source, krill, caused by a marine heatwave dubbed 'The Blob'.
- Originating in 2013, 'The Blob' was a dense pool of warm water that significantly raised Pacific Ocean temperatures, in some places by over 4.5 Fahrenheit.
- The elevated temperatures fostered toxic algae blooms, which decimated krill populations and other marine life.
- Scientists suggest blue whales ceased singing due to the immense stress of spending all their energy searching for food, a situation exacerbated by climate change.
