## Whale season ends early
Brazil’s humpback whale season ended with fewer calves than usual.
## Fewer calves recorded
Calves accounted for 3.35 percent of observed whales this year, down from 9.98 percent since 2014.
## Climate change impact
Global warming may be reducing krill availability in Antarctica, affecting whale food sources.
## Whale breeding challenges
Whales that don’t feed properly become less fertile and risk losing calves during migration.
## Stranding patterns shift
Santa Catarina and São Paulo recorded more strandings than usual this year due to fewer calves.
## Krill availability link
Low krill availability in Antarctica correlates with increased strandings in 2010, 2017, and 2018.
## Future risks
If krill availability continues to decline, more whale deaths may occur next year due to cumulative effects.
## Key takeaway

Brazil’s humpback whale season ended with fewer calves due to climate change affecting krill availability.
