And he's got a lot to be mad about. As played by Downton Abbey's Jim Carter, Santa is fed up with the havoc that global warming is wreaking on his home at the North Pole, and he's recorded this manifesto-style PSA for Greenpeace to plead for assistance.
"I have written personally to President Obama, President Putin – all world leaders," he grumbles. "Sadly, my letters have been met with indifference. Needless to say, these individuals are now at the top of my naughty list."
The image of St. Nick the ad presents is worlds away from the cuddly Santa of legend – he looks more like a Chinese dissident or, as Greenpeace's detractors might say, a terrorist – but the message it sends is certainly striking. Ignore global warming and the real North Pole may turn into just another Santa Clause: a thing we tell our children about, that doesn't actually exist.
