Climatology ?

[Wizjolnir]

The Pathfinder products lack of structured information about the climate in Golarion.

How you handle the climate in Golarion?

They have said many times, as they lack the scientific knowledge for some of these things, they made Golarion as close to Earth as possible. So that you could use real world climate information, Based on the inner sea region being europe/eygpt

This answer is not precise enough not to say it is vague.

For example what are the latitudes on the map?

Where is the line on the map between the cold, temperate, tropical and subtropical climates?

An so on.

There is no need to be a scientist to answer this question.
