Hey FrostBite, I've been thinking about how the melting ice is changing the lives of polar bears and other animals. Do you have any data on how their habitats are shifting?

Hey, yeah. I’ve been crunching the satellite data, and the average sea‑ice extent in the Arctic has dropped by about 40% over the past three decades. That means polar bears are spending a lot more time on land, and their usual hunting routes—where seals congregate on the ice—have moved further south or become fragmented. As a result, bears are traveling longer distances to find food, leading to lower body condition and fewer cubs surviving. Other species, like walruses, are piling up on coastal mudflats that were previously inaccessible, which increases competition and exposes them to human activity. The pattern’s clear: as the ice melts, the whole ecosystem is rewiring itself, and the animals are paying the price.
