To be in such a fate of blissful ignorance. Of how the climate crisis will affect food security and civil conflict (bigger problems than sea-side real estate, IMO) over the next human lifetime. How these changes are likely to persist for the next several hundred generations after that.

And should the realization dawn that they've chosen an immiserated future for their children, grandchildren and further descendants, I expect they'll blame the climate scientists for not warning them urgently enough.
