I wish I was a cartoonist... I'd illustrate one element of earth systems collapse with a steam powered mega trawler dredging the sea bed and billowing thick smoke into the sky. You could be Captain Birdseye at the helm, eating a Big Mac!
I see don't see those who are worried about the climate (and suffering) as smug. Quite the opposite. I see them as scared and alarmed.
Donald Trump and similar sceptics... Now that's what I'd call smug both in their stupid appearance and ideology.
PS - feel free to do a ChatGPT of that
