Cool It! is a brainless game of take that! from the UCS (Union of Concerned Scientists). Update: see comments. Pick cards, play the solutions on yourself until you’ve won, or play problems on others to slow them down.

While they sensibly include more solution cards than problem cards so that the game will eventually terminate, I don’t know what kind of message it sends to kids that a) there are more solutions than problems for our environmentally challenged planet, b) I can solve my problems while trying to stop you from solving yours, and c) applying solutions is both simple and a matter of luck.

But what they hey. Welcome to the card game business.
