Time to re-introduce an old word into our modern vocabulary and then propose a modern variant.
a tax raised to pay tribute to the Viking raiders to save a land from being ravaged
Since the raiders today are not Viking [they were just visiting Copenhagen at the time] I propose the word Copengeld. All the tribute money is dressed up with the pretense of being for Copin' with the effects of climate change.
Either way, it's just another shakedown.
