Pray for global warming - no matter the cause. It can get real cold out there and has been for most of earth's history according to this chart. We are in one of just a few peak temperature cycles which historically have been hotter and have not lasted long (relatively speaking).
Judging from the graph, if one were to normalize the tempurature, it would be about 5 degrees below the 1996 nominal that was chosen as a baseline for the graph. Immagine the average tempurature 5 degrees colder on average. Winter would start in Early Novemeber and last until mid April. 6 full months of winter as opposed to 3 1/2 months.
