A survey of climate change in theater here and in the UK in the New York Times focuses mostly on "This Clement World," a new musical play by Cynthia Hopkins, and includes a telling quote from the writer:
“Alcoholism is an excellent metaphor for the climate change crisis,” she announces at one point onstage. “We’re addicted to behavior that is making us sick.”
Idea makes sense, if you think that denial is central to alcoholism and our culture's response to climate change.
Here's a trailer, narrated by the playwright.
I admire the thoughtfulness, but what sticks with me is the kazoo.
