I can only guess that this is related to the infestation by druids.. or possibly a side effect of hosting Cenarius. He is a God isn’t he?

No, he’s not. Though he may be able alter the weather, he’s not a god. Or at least, not a full one. Cenarius is the son of Malorne, the aspect of the Stag, and Elune, the Goddes of the Moon, making him a Demi-God.

Also, another thing to consider is what impact Warm Oceanic Currents have on the ecology. Consider for a second that the southern tip of Greenland is only about two degrees away from the northern tip of Scotland. Yet the difference in climates is far too much to justify just from those two degrees. Due to the Gulf Steam sending water into the North Atlantic Current, this causes warm water to raise the average temperature in Europe, making it a similar climate to the United States, despite the huge differences in latitude.

Areas like Darkshore, despite their far northern locations are much more temperate than they should be. I would imagine that this is due to a warm oceanic current coming from the south, carrying it’s heat up to Darkshore.

You really have a sense of humor or just too much time on your hand to thing of stuff. Yet makes for interesting reading.

It interesting to think that since Winterspring is in the north and snowy. Where is the snow lands of both the southern continents assuming the world of Azeroth is round and have a north and south pole. Maybe there is missing lands maybe dunno.
