The word that Mrs. Bronson is unable to put into the hot, still, sodden air is 'doomed,' because the people you've just seen have been handed a death sentence. One month ago, the Earth suddenly changed its elliptical orbit and in doing so began to follow a path which gradually, moment by moment, day by day, took it closer to the sun. And all of man's little devices to stir up the air are now no longer luxuries—they happen to be pitiful and panicky keys to survival. The time is five minutes to twelve, midnight. There is no more darkness. The place is New York City and this is the eve of the end, because even at midnight it's high noon, the hottest day in history, and you're about to spend it in the Twilight Zone.This sign post is relative:
On January 3rd, 2019, Earth reached the point in its orbit where it's at its closest approach to the Sun: perihelion. Every object orbiting a single mass (like our Sun) makes an ellipse, containing a point of closest approach that's unique to that particular orbit, known as periapsis. For the past 4.5 billion years, Earth has orbited the Sun in an ellipse, just like all the other planets orbiting their stars in all the other mature solar systems throughout the galaxy and Universe.
But there's something you may not expect or appreciate that nevertheless occurs: Earth's orbital path doesn't remain the same over time, but spirals outward. This year, 2019, our perihelion was 1.5 centimeters farther away than it was last year, which was more distant than the year before, etc. It's not just Earth, either; every planet drifts away from its parent star. Here's the science of why.
The force responsible for the orbits of every planet around every solar system in the Universe is the same: the universal law of gravitation. Whether you look at it in terms of Newton, where every mass attracts every other mass in the Universe, or in terms of Einstein, where mass-and-energy curves the fabric of spacetime through which other masses travel, the largest mass dominates the orbit of everything it influences.

Minor exercise in the care and feeding of a nightmare, respectfully submitted by all the thermometer-watchers in the Twilight Zone.
