Here's my American-centric hot take. People here feel powerless. This isn't a problem which can be dealt with on the personal level. The politicians are largely useless. One party completely denies there's a problem and actively derails any governmental attempt to address it. The other party is often timid, scared of its own shadow, and only proposes weak remedies.

Furthermore, most of us here agree that it's happening and don't argue much about the root causes. All of that adds up to lack of discussion. Can't do much about it. Have had little luck influencing those that can. There's little for amateurs to discuss regarding the underlying science. It's sometimes cathartic to publicly pronounce one's feelings of fear & loathing in threads like this, but that also doesn't lead to good conversation.

And so we end up talking about silly things like flying taxis because that lets us avoid the soul-crushing doom for another hour.
