I think you may have not entirely understood where he was going with that. It's a metaphor for entropy. It's actually a much more poignant and beautiful topic than something as short-term and universally inconsequential as climate change on earth.

That is indeed a more interesting interpretation. Thank you for making this already great story even greater to me!

I like the way the narrator-hero is trapped in a sinister bell jar world and yet works optimistically to improve his knowledge of it. Regardless of outcome he sees no malevolence built into reality.

Also a metaphor for the Simulation Hypothesis!

I disagree- these mechanical people are well-nigh immortal and will leave to see the end of their world, no one alive today on earth will live to see the heat death of the universe. However, we might just get to experience the effects of climate change.

The beauty of literature is we can both the right - our interpretations of the work is what matters. Additionally, while they are inspired by them,authors do not necessarily do a 1:1 mapping of real world issues to their stories

Do you remember how they were talking about pressure equalization or looking for other universes that existed at a lower pressure? It's a pretty direct mapping from the story to (neg)entropy; it's not related to climate change except in the very vaguest sense.

More than a metaphor, it is actually about entropy.
