1 BACKGROUND The Arctic is warming four times faster than the global average (Rantanen et al., 2022), thus we expect to see the earliest and most significant effects of climate change in Arctic ecosystems. The increase in spatial extent and duration of the Arctic Ocean's ice-free season is of particular concern. All credible emission scenarios predict that Arctic summers will be ice-free by the mid-20th century (Kim et al., 2023).

AbstractThe Arctic is the fastest-warming region on the planet, and sea ice loss has opened new habitat for sub-Arctic species such as the killer whale (Orcinus orca). As apex predators, killer whales can cause significant ecosystem-scale changes, however, we know very little about killer whales in the Arctic. Setting conservation priorities for killer whales and their Arctic prey species requires knowledge of their evolutionary history and demography.
