Being originally from California, I have enjoyed the longer, cool but sunny fall weather we have had in Minnesota in the past few years.
True Minnesotans, however, are anxious for snow and the colder weather that goes along with skiing and sledding. Instead we have scenes like this through most of November now.
I think we all realize that weather patterns are changing, and this graphic below summarizes those changes nicely to show the overall warming trend in a northern U.S. state. Minimum temperatures (overnight lows) have risen faster than maximum temperatures, with the result that winter temperatures have risen more than the average.
And the effect of those temperature changes is what we see happening all around us: delayed leaf drop, delayed snowfall, decreased winter precipitation, earlier ice-out on the lakes, etc.
What will happen (or is happening) to the biota adapted to a previously colder climate?
