Most terrestrial species in biodiversity hotspots in North America have been projected to be negatively impacted by climate change . About ~80% of projections for assessed species showed a negative impact of climate change, with ~25% at very high risk of extinction . Alterations to vegetation that would have ecosystem-wide impacts, such as a shift from oak-dominated forests to predominantly hickory and maple species in the Appalachian Forests   or the continued shrinking of tundra ecosystems, have also been projected. Range shifts have been projected for a variety of plants  and vertebrate taxa . Sizeable range loss, which particularly affects endemic species, is projected with higher levels of climate change. Adaptation in the agricultural sector poses an additional risk to remaining wildlife habitat .
