Summary

Story summary

Polar bears in Norway's Svalbard archipelago have gained body fat despite shrinking sea ice.
A study of 770 bears from 1995–2019 links this to land-based prey, including reindeer and walruses.
These prey rebounded after over-hunting, supporting higher body condition after 2000 despite ongoing ice loss.
Scientists caution continued ice loss could threaten health and survival, even as the findings challenge the universal decline narrative.

History

Historical Context

Since 2000, conservation efforts have aimed to protect polar bears, whose populations are threatened by climate change and habitat loss. The International Polar Bear Conservation Plan emphasizes their ecological importance in the Arctic. Recent studies indicate that polar bears in Svalbard have adapted by gaining body fat from land-based prey, yet ongoing ice loss remains a critical threat to their survival.
