These days, all it takes is a web address to concoct any organization one can imagine and label it international (or intercosmic) if one wishes.

There appear to be legitimate organizations called:
The International Trombone Association
The International Ergonomics Association
The International Dyslexia Association
The International Downtown Association
The International Jugglers' Association
The International Twins Association
The International Zinc Association
The International Nanny Association
The International Hedgehog Association and
The International Polka Association.

Why, therefore, would there not be an International Permafrost Association?
