Reply #5: Snow does not necessarily mean the temperature is colder in the

region. It does reflect that the precipitation is higher and an increase in precipitation is a symptom of global weather change.

... an increase in the average global temperature is very likely to lead to changes in precipitation and atmospheric moisture because of changes in atmospheric circulation and increases in evaporation and water vapor.

If I am not mistaken, the temperatures in these regions are not above normal, the snowfall/blizzards are caused by an increase in precipitation in the regions. If it weren't freezing the areas would be experiencing higher than normal rainfall.
