The great question of global warming is, "What happens to my home? Will it be warmer in the winter, but not the spring? Less snow? No snow? More rain, less rain?"
The answer is complex, but our best bet is that over the past 20 years, most of North America has seen more of the extremes (drought, flood, snow, rain, heat, cold). This unpredictability is pretty much the norm for any chaotic system going through a phase change.
Brian Fagan (an anthropologist interested in cultural records of global warming in the warmer "Middle Ages") was on the Daily Show with Jon Stewart last week. It wasn't terribly detailed regionally, but that is in line with our chaotic change issue. It is interesting hearing how he worked the analysis for a lay audience with no background in medieval climatology. This is truly where the rubber meets the road.
Design for chaos.
