We’re making it tough for Santa Claus

These days, kids have a lot more to worry about for Santa Claus.

It used to be that young children wondered about the reality of Santa Claus. Would Santa show up on Christmas Eve?  And parents turned the whole controversy to good ends by threatening us that Santa would not show up unless we were good.

These days, kids have a lot more to worry about for Santa Claus. The North Pole is a lot warmer than it was a few decades ago, thanks to the ongoing global warming that we are causing.  The arctic sea ice is a lot thinner than it used to be, and there’s a good chance that Santa’s sleigh will break through the ice and sink in the cold arctic waters.

Reindeer populations are in steep decline over much of the arctic landscape. Santa may be able to keep his team healthy for a few more years, but when he needs some replacements, reindeer may be hard to find. I’ve heard that Dasher has had a few bouts of arthritis.

And forest ecologists, using remote sensing to monitor forest health, report that northern spruce and fir forests have been burning more frequently as a result of hotter, dry summers. The spruce budworm has also attacked a lot of trees. These changes in the environment could lead to a real shortage of Christmas trees for Santa.

Yes, Virginia, there is a Santa Claus, but we better watch out for Santa, the elves, and the reindeer or we’ll not hear those hooves on the rooftop.
