Rewilding the Arctic with mammals likely to be ineffective in slowing climate change impact

A new study published in PNAS found that large mammals died out at the end of the last ice age due to a warming climate and vegetation expansion. Rewilding efforts with animals like bison and horses are unlikely to reverse this trend, as climate change remains the primary driver of ecosystem changes.
