"Save Christmas"? I thought "Christmas" was about the Birth of Christ. If we compare the climate of today versus the time of Christ, we see there is little to worry about.
According to a peer-reviewed temperature reconstruction of the last 2,000 years, temperatures when Jesus walked the earth were about the same as today! That is known to climatologists as the "Roman Warm Period" and was a time when civilization was making great progress.
Temperatures then fell as did the Roman Empire when people relocated to escape the cold. The world then warmed with temperatures warmer than today during the MWP = medieval warm period.

So, if today's temperatures are about the same as at the time of Christ, I don't think we need to be too worried about "saving Christmas."
Based on the historical record, humanity should fear global cooling much more than warming. I'll have more on that topic next week.
