<p>A two degree difference is massive for the environment in given climates. This is mainly because higher latitudes have larger changes than lower latitudes. For example, a two degree global change would mean maybe 7-8 degrees in places like northern Europe and Canada, with minimal change at the equator.</p>
<p>Anyway, this isn’t a climate lesson. As far as comfort goes, a 5 degree difference isn’t much. Whether it’s between 20 and 25 or 50 and 55 or 80 and 85, it’s not much.</p>
<p>Also, I’d argue that Detroit is probably sunnier than Ann Arbor considering A2 gets more of the precipitation dumped on it from the west before it reaches Detroit. Probably not much of a difference, though.</p>
