•temperature extremes

Among the existing climate classification methods, the Köppen scheme only needs temperature and precipitation (and their annual cycle pattern) to define and has strict classification standards, clear boundaries, which allowed it to become one of the most widely used methods.  

Explanation:

temperature extremes, humidity, and precipitation, though vegetation types may vary. Maybe soil. latitude and longitude for direction. But mainly temperature and precipitation because those factors never change.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
