Santa Claus has taught reindeer to circumnavigate the globe and non-union elves how to make iPods, but is he adequately aware of the threat global warming poses to his North Pole compound? New Jersey Senator Robert Menendez hopes so. That's why he's written Santa an open letter on the Huffington Post warning that climate change could threaten Santa's North Pole home. The letter contains some harsh climate truths, and, of course, an invitation to visit New Jersey. (What is it with New Jersey politicians and inviting people to come to New Jersey?) Some highlights:

Dear Santa Claus,

I am writing out of concern, because you may have to move from the North Pole due to the dramatic melting of Arctic sea ice
...
Scientists overwhelmingly agree that polar ice is melting because of greenhouse gas pollution and I am working hard to reduce these emissions. But there is probably nothing we can do in time to save the North Pole. I am worried about your safety and your ability to deliver billions of Christmas gifts if the ice cap on the North Pole no longer stays frozen all year. What will happen to your house, your workshop, the elves' houses and your reindeer barns?
I want you to know that if you want to relocate to the beautiful state of New Jersey, I would be proud to assist you. But given the climate you are accustomed to, I will understand if you would like to relocate to the South Pole. Just be sure not to move to the Antarctic Peninsula or West Antarctic ice sheet, areas that are also experiencing rapid ice melt.
Please know that I will work to mobilize the U.S. federal government to assist when you relocate. I am sure we can both agree that on a warming planet, we need to do all we can to save Christmas.
We're guessing Menendez is going to have to wait a few days for that response.
