Less than half. That is what a 2023 review of climate-driven range shifts found — less than half of displaced species follow any predictable direction. Barnacle geese rerouted their entire migration in less than a generation because the grass in a Norwegian archipelago came up early. Arctic caribou face rain-on-ice events crusting the tundra so vegetation locks underneath. Polar cod — the fish that channels over 70% of energy transfer between zooplankton and whales, seals, seabirds — is being displaced. Researchers call it borealization. We are watching ancient food webs unspool thread by thread.
