Story summary

A University of East Anglia study finds polar bears in southeastern Greenland showing genetic changes linked to climate change.
Researchers report increased activity of "jumping genes" tied to heat stress, metabolism, and aging, suggesting adaptation to warmer conditions.
More than two-thirds of polar bears are projected to face extinction by 2050, underscoring the need for conservation and reduced emissions.
