Climate change must be felt to be understood. Depends what you're trying to demonstrate. I think the greenhouse effect is cool. Carbon dioxide is useful, it's just not in the right place. How might we build a bunch of rooms with different amounts of carbon dioxide in them. And big lamps. In the rooms with low carbon dioxide, it's cool. With rooms with lots of carbon dioxide, it getd hotter and hotter. Even a simple physicics simulator app would be cool, different ppm of carbon dioxide, and showing the change/temperature stability. I remember fooling around with a physics simulator as a kid, springs and boxes, then you hit go and they all move with gravity. Power it with data from the open climate API at http://carbondoomsday.com http://carbondoomsday.com Keep the ideas coming!
