An official climate debate could be great

I would welcome a public debate on global warming. Let them make their best case, and then watch them try to tap-dance around the actual facts. 

EPA Administrator Scott Pruitt’s proposal to hold a TV debate on climate change science makes a lot of sense.

This idea is very different from the Red Team exercise that he mentioned previously, which has seen a great deal of discussion, such as here and here. The Red Team exercise would be a highly technical scientific debate. In contrast a TV debate would be designed to, as Pruitt puts it, reach the American people. It could also be a great teaching tool.

How to design such a debate raises some challenging issues. These include how many debaters should participate and who should they be, what the format should be, and at what education level should the scientific issues be discussed?
