why have plants and animals have been able to adapt to change in climate in the past?

One major tool for adaptation in nature is migration. This tool has two requirements: Time and space. The species need time to relocate to new areas, and they need the space to establish in new locations. Some species live in close connection to other species at their location, thus the whole ecosystem might need to relocate. This might not be possible due to topographic features or human intervention. This might be a frog living near mountain tops, and an new (and warmer) climate hav no mountains with favourable temperatures. Or there is a farmland preventing a certain grass to migrate to new areas. The other factor was time. The ongoing climate change is fast. If we see a 3 degree temperature increase in this century are there many species that don’t have the time for adaptation to a new climate.
