How Killer Whales are Changing the Arctic

Life in the frozen North is changing. ❄️Due to climate change, seasonal pack ice extends much less than it previously did, meaning that once closed-off waterways like Eclipse Sound are now open to visitors almost all year round. And when those visitors are highly skilled predators like killer whales, the entire ecosystem could be turned on its head...

Shot in the Canadian Arctic, our latest video explores the effect that rising sea temperatures are having on iconic polar species like orcas and narwhals. We explore the importance of ice in shaping local ecosystems and find out why killer whales are the perfect predators.
