Executive Summary
Climate-driven sea ice loss is reducing whale prey and slowing recovery, from southern right whales to gray whales across the Southern Ocean and Arctic
- Southern right whales are now calving every four years instead of every three
- The slowdown has been evident since about 2015, according to long term data
- Researchers link the change to Antarctic sea ice loss and shifting marine food webs
- Less sea ice is reducing krill availability and forcing whales to expend more energy feeding
- The study says stronger marine protections and greenhouse gas cuts are needed
- Gray whales in the eastern North Pacific have fallen to about 13,000 in 2025
- Arctic warming and earlier sea ice melt are hurting prey supplies for gray whales
Quick Facts
- What: Climate change is slowing whale reproduction and weakening recovery
- Where: Antarctic feeding grounds, Oregon coast, and Arctic feeding areas
- Why: Sea ice loss disrupts prey webs and reduces food for whales
- Who: Researchers and whale populations in the Southern Ocean and North Pacific
- When: Since about 2015 for southern rights and by 2025 for gray whales
