Why is the entropy of the universe always positive? And why does a larger temperature mean it has a smaller change in entropy?

I think you mean "change in entropy." The reason why entropy is always increasing in the universe is because of the big bang theory and how the universe is always expanding, and therefore occupying a forever increasing number of possible states.

The change in entropy of the universe is always positive because some form of energy is always released (whether that may be from the system or the surroundings), even if it's endothermic.
