 Air conditioning is kind of a Jekyll and Hyde situation. It really is holding us back, and it's undercutting our ability to mitigate climate change, but it's going to be necessary for adaptation to climate change. So the less of it we use now, the less of it we're going to need in the future. Jekyll and Hyde, or damned if you do, damned if you don't. Yeah, can't live with it, can't live without it.
