There is a surprisingly prescient scene in Lucifer’s Hammer.
The astronauts are looking down on Earth, talking about how the national borders aren’t visible from space.
One says it is really dangerous because an ice age is approaching.
The other says it may have started except it is stalled by global warming - and we’re running out of oil.
40 years later, still liberals afraid of peak oil and debating climate change.
I loved Lucifer’s Hammer. I thought it was a good candidate for a miniseries.
