A discussion of the changes that [increased CO2] will bring to the climate? as in, the likely range of temp. increase if we don’t mitigate? I was there last month, & I don’t remember mention of anything like this:

(When I was there, in the “humans change the world” nook, the 2 panels adjacent to the “CO2 concentration” chart (only the last inch or two of which showed the present-day upward CO2 shoot – were displays of “you are an ecosystem” and a pure “art” one; perhaps these two panels have been replaced? If you’ve got photos of the “discussion” part, I’d love to see what it said.)

(I’d especially be interested to know if it lays out what our options are, for addressing climate change.)

[CZ: I can't give a definitive summary, because there was too much stuff to take in deeply in one visit. But the climate theme is strong throughout, with human evolution tied to changes in the climate. At the end of the exhibit, when it turns to the future of humanity, there are charts showing increased carbon dioxide concentrations and a discussion of the changes that will bring to the climate. The irony that the man who gave the hall his name has also funded global-warming denialists is rich and thick.]
