I highly recommend it for everyone - it will probably convince those that are on the fence or haven't been interested, and it will deepen the understanding of those who have been paying attention. In the first room of the exhibit was a large, unequivocal statement on the wall to the effect that the current warming of the planet is caused by humans.
My only caveat regards the cost of a visit to the museum: $24 for adults, $18 for seniors. I don't know the price for children and students. The ticket gets you into the whole museum, where most of the other exhibits are open to visitors, whereas the Climate Change Exhibit requires the ticket to enter. So I recommend going with time and energy to take advantage of other exhibits, spending as much time there as possible. We only had four hours between buses and weren't able to go through other amazing areas that just caught our eyes in passing: Primates, Animals of Asia, Civilizations of Asia, and much more.
