How does dwarf fortress generate the civilizations while doing world gen?
Does it just pick places (that are not ocean) at random, or is there a more advanced algorithm?

No. You can start a new game in your current world once you quit the current one, or you can start a new world. Dwarf Fortress does not allow for two games to go on in the same world because of the unspecified ways they might interact.
So from what I gather is that you want to create a specific map or decrease the temperature on an already created map. I don't know the latter but I can help with the former:
- Open up DF
- On the main screen select Design New World With Parameters
- Select one of the presets and press the e key
- Scroll down till you see the following (should be the second page):
- Change the Maximum Temperature and Minimum Volcanism values
- good values for Temperature are ~45
- good values for Volcanism are >50
- Finally, to ensure a good Taiga you'll want to play with the Rainfall parameter.

You can get some idea of what happens by opening your generated world in legends mode. There's an option that lets you see the spread of different civs over time on a map.
Basically, the way it seems to work is that the game randomly picks suitable initial city sites for each civ, and they gradually spread out from there, founding new sites. Where the areas of influence of two civs overlap, they may come into conflict. Apparently, this is tied to the history generation, which records things like the founding and fall of city sites, as well as major battles (which might sometimes result in a site changing ownership).
Also, different civs appear to have different requirements for starting sites: for example, elves always start in a forest, while dwarves seem to start near mountains and humans on plains. Evilness, savagery and aridity also seem to affect things; dial those high enough in the worldgen params, and it's quite easy to end up with a world with no playable civs.
