How did a warming climate 12000 to 1 years ago impact the paleo-indians living in the americas at the time

The most significant difference was that with a warmer climate they were able to gather more of different berries and all the different nuts and seeds that one could find in a warmer environment. Another thing was that there was also more animal meat to be hunted because of the warmer climate, other animals were also able to sustain themselves more easily, enabling the Paleo-Indians a relatively easier life.
