Russ,
This is a real possibility. There has been some theorizing regarding the decline of Fraser fir (Abies fraseri) by the Balsaam Woolly Adelgid in the higher elevations of the Appalachians, that the effects of acid rain may be weakening the trees allowing the adelgid to finish them off. Kind of a two-fronted attack! Most of the effected natural stands tend to be facing the Tenn. Valley where air pollutants tend to migrate to. I suspect that there are other examples out there as well.

It is an extremely common tree in areas far south of New England and most generally the trees appear to be healthy. Because we are closer to the sources of acid deposition and pollution from coal fired power plants that are causing great harm the north woods I would at least want to consider that air pollution rather than climate change is a major factor in northern sugar maple decline.
