Population range shifts including migrations are common adaptations to climate changes across multiple time scales and ecological systems in the past and in response to current warming . Poleward expansions and retractions  as well as migration upslope and downslope in response to warming and cooling were common adaptations . During warming periods, diversity loss was common near the equator , while diversity gains and forest expansion occurred in high latitudes . Comparison of contemporary shells and skeletons with historical collections in museums  and the analysis of skeletons of long-lived organisms  indicate significant climate-induced change in organismic growth rates today .
