How did a change in climate cause the beginning of the Neolithic Revolution?

It caused humans to have to settle down.

Explanation:

When the climate grew warmer, the need to build places to settle in also grew. Before, people roamed freely all the time. This climate change also influenced the start of farming. It became much easier to begin farming, and building a house next to your farming area. Thus, began an agricultural revolution and a modern way of living. All-in-all, people had to adapt to the warmer temperatures, which lead us into our set-up of modern civilization.
